Supreme Leader: Biodiversity is not only the foundation of sustainable development, but also the goal and means. We must use the way of nature to nourish all things, seek development opportunities from the protection of nature, and achieve a win-win situation for ecological and environmental protection and high-quality economic development.

　　This sentence is from the important speech delivered by the Supreme Leader President at the United Nations Biodiversity Summit on September 30, 2020.

　　Biodiversity is the result of billions of years of development and evolution of life on earth, and has important ecological, economic and cultural values for human survival and development. Protecting and restoring biodiversity and improving the diversity, stability and sustainability of ecosystems are conducive to improving our living environment, increasing food and resource supply, and promoting sustainable economic and social development. Conversely, if biodiversity is lost, ecosystems will be out of balance and human survival and development will lose an important foundation.

　　China has a vast territory, land and sea, and has given birth to rich and unique ecosystems, species and genetic diversity. As one of the countries with the richest biodiversity in the world, China has always attached great importance to biodiversity conservation. Especially since the 18th National Congress of the Communist Party of China, under the guidance of the Supreme Leader’s ecological civilization thought, all localities have adhered to ecological priority and green development, and continuously strengthened and innovated biodiversity protection measures.

　　为了保护重要自然生态系统和生物资源，目前，我国把超过30%的陆域国土面积划为生态保护红线，可有效保护90%的陆地生态系统类型和74%的国家重点保护野生动植物种群。经过多年移民搬迁和生态修复，我国设立的第一批5个国家公园有效保护了东北虎、大熊猫等珍稀野生动物及其栖息地，成为万物和谐共生的美好家园。同时，为保护一些濒危物种，我国相继设立国家植物园、野生动物救护繁育基地、种质资源库、基因库等，加大对濒危野生动植物的迁地保护，加强对生物遗传资源的收集保存。为保护候鸟迁徙通道，许多地方加强当地湿地保护，让水草丰茂的栖息地成为候鸟迁徙途中的重要“驿站”。随着生物多样性保护宣传教育和科普活动持续开展，公众参与生物多样性保护的方式更加多元化，参与度全面提高……经过不断探索，我们走出了一条中国特色生物多样性保护之路，各地也在保护自然中逐渐找到适合自身的发展机遇。比如，一些地方在国家公园以外的周边地区发展生态旅游业、林下经济等，让从保护区搬迁出来的当地百姓端上“绿饭碗”，吃上“生态饭”。

　　中国式现代化是人与自然和谐共生的现代化。尊重自然、顺应自然、保护自然，是全面建设社会主义现代化国家的内在要求。新征程上，我们要把生物多样性保护作为生态文明建设重要内容，既总结好已有经验、巩固好已有基础，又不断探索创新保护方式，持续推进生物多样性治理体系和治理能力现代化，进而持续改善自然生态系统状况，提高生态产品供给能力，实现自然生态系统良性循环，不断满足人民日益增长的对优美生态环境需求。

　　There are not many days between "stepping on the brakes" in late April and regaining the upward trend since early May.

　　On May 20th, the international gold price once again set a record high. London gold price and COMEX gold futures price both broke through the $2,440/oz mark and continued to attack. Domestic gold prices opened sharply higher, and SHFE gold in Shanghai Futures Exchange hit 582.44 yuan/gram. (Source: Wind)

　　After a break in late April, the price of gold once again opened the rising channel in May.

　　In the past two weeks, the inflation, employment, economic growth and consumption data released by the United States have weakened in an all-round way, the US dollar index and US bond interest rates have fallen back at a high level, and the market’s expected first interest rate cut has been advanced again, and macro bets have boosted the recovery of gold prices; On the weekend, the risk worries caused by the geopolitical conflict in the Middle East fermented and brought more safe-haven funds into gold.

　　Since March this year, the global gold price has ushered in a remarkable surge, and the gold price has been "soaring" all the way, and the banner of a record high has been refreshed again and again. At present, in the face of the complex intersection of short, medium and long-term influencing factors, how do you view the future trend of gold prices? Standing above the $2,400/oz mark of COMEX gold, can you still allocate gold?

　　The gold of the times

　　"Sometimes Betrayal" and "Never misjudge. "

　　How to treat the future trend of gold price? In the long history, gold has experienced many "bull and bear markets" step by step.

　　Before 1970s, the global monetary system actually took gold as the "anchor", with the US dollar pegged to gold and the major western currencies pegged to the US dollar. After the collapse of the Bretton Woods system in August 1971, it declared the end of the gold-linked era.

　　Since then, gold has experienced nine complete big markets, lasting for 32 months on average and increasing by 172% on average.

Source: Wind, open sourceresearch institute

　　The boosting factors of each gold bull market are closely related to the context of its times and are different from each other. However, no matter how the times change, most of the time it revolves around several real pricing logics closely related to the characteristics of gold itself:

　　① Financial attribute: gold does not bear interest, but it bears interest when holding US Treasury bonds. As the opportunity cost of holding gold, the real interest rate of 10Y US Treasury bonds is negatively correlated with the price of gold.

　　(2) Safe haven property: When financial, economic and geopolitical fluctuations or crises occur, the demand for safe haven of gold is often increased, which leads to a risk premium.

　　③ Currency attribute: Gold has certain substitution for the US dollar system, and the weakening of US dollar credit will benefit gold.

　　4 Commodity attributes: Gold can resist inflation, and the dollar will depreciate with inflation, so the higher the global inflation, the higher the price of gold.

　　This round of gold rising cycle began in November 2022 and has lasted for 16 months, with an increase of more than 40%. Then, from the above pricing logic, what factors have started this round of gold bull market?

　　From the traditional pricing framework, gold is a non-interest-bearing asset, and the real interest rate is the opportunity cost of holding gold. In other words, the interest rates of gold and US debt are in the same boat, and the downward interest rate will push the price of gold higher.

　　The rush of funds to the Fed’s interest rate cut expectations and the expectation of the easing cycle often become the catalyst for the rise of the gold market.

　　In the second half of last year, the Federal Reserve officially completed the current round of interest rate hikes for 11 times. After that, the US economic data slowed down in October, and the Fed’s interest rate meeting in November was biased. So far, it is the most historical interest rate hike cycle in the United States since 1980. It has basically become a consensus that when interest rate cuts become the general trend, gold will enter the rising market.

　　The trend of gold in the past 20 years can be found that the market of gold often begins with the end of interest rate hike, and finally monetary tightening or economic recovery. For example, at the end of interest rate hike in late 2006 and late 2018, the price of gold started a big rising cycle and the market went all the way to the end of the interest rate cut cycle.

　　However, in this gold bull market, we will find that the trend of gold has undergone subtle changes, and it seems that it is no longer satisfied with its limited play under the dollar order.

　　Especially since the beginning of this year, gold has become the focus not only because of its remarkable increase, but also because of its "challenge" to the traditional pricing framework: the law that the real interest rates of gold and the dollar and the United States usually change in the opposite direction has "failed".

　　Since April, the nominal interest rate of 10-year US debt has surged to nearly 4.7%, the real interest rate has risen from 1.87% to 2.41%, the US dollar index has risen from 104 to 106, but gold has soared by over 7% for a time, and it has only recently been slightly adjusted back. (Source: Wind)

　　Is there a new and more important pricing factor at work in this seemingly contradictory trend, or is it just an illusion caused by short-term emotional excitement?

　　Tracing back to the source, the bottom of the logic is the ultimate deduction of the safe-haven property of gold in the process of reshaping the global political and economic system. The occurrence of deviation and the failure of the anchor actually increase the "fragility" against the dollar.

　　Gold is a mirror image of the dollar, and the market in recent years has cast a vote of no confidence in the dollar. Although after the collapse of the Bretton Woods system, the world entered the credit currency system represented by the US dollar, and gold no longer has the functions of circulation and pricing, but it still maintains the role of value storage. Therefore, once the credit currency system represented by the US dollar is in crisis, gold will rise sharply.

　　Internally, in recent years, the US finance has continued to expand substantially, the debt scale has accumulated rapidly, and the problem of fiscal sustainability has caused social concern. Fitch downgraded the credit rating of US debt, which became the internal cause of the credit decline of the US dollar system. The rise of geopolitical risks and the rise of anti-globalization thoughts are the external causes of the decline of the credibility of the US dollar system. The freezing of foreign exchange reserves in some countries in the geopolitical conflict between Russia and Ukraine accelerated this process.

　　Internal and external factors are superimposed, the credibility of the dollar system is declining, and the world has entered the process of "dollarization". Central banks around the world have turned to gold as an anchor to stabilize foreign exchange reserves.

　　Gold sometimes seems to "betray" the traditional analytical framework, but what is never misjudged is the trend and background color. The gold of the times is generally the same.

　　The golden age

　　"Megatrend" and "Masterpiece"

　　After experiencing record highs again and again, the value of short-term transactions will decrease when standing above the threshold of COMEX gold of $2,400/ounce. A smoother rise may need to wait for catalytic factors. This is a change, but there are some unchanged ones, which ensures that the value of gold in large-scale asset allocation is still outstanding.

　　On the one hand, the "megatrend" under the current narrative background of the world remains unchanged, the US debt problem is hard to return, geopolitical events are frequent, the pattern of anti-globalization and dollarization may be further deepened, or the global central bank will continue to increase its holdings of gold, and the logic of long-term rise in gold prices is still there.

　　First, in the second half of the year, with the gradual realization of the expected interest rate cut in the United States, the downward trend of the real interest rate of the 10-year US debt is expected to support the gold price to a certain extent. However, considering that the interest rate cut is expected to rush since 2023, the persistence and elasticity of the subsequent gold market depends on the change of the expected difference.

　　Second, this year may become the biggest election year in history. In recent years, overseas risk events have continued, and the global economic policy uncertainty index center has risen, which also provides room for high gold prices.

　　Third, the game between big countries in the fields of politics, economy, industry and finance has been fully rolled out. Anti-globalization has brought about an increase in friction costs, superimposed energy transformation and inflation stickiness in the service industry, and it may be difficult for overseas long-term inflation centers to fall back quickly.

　　Fourth, on the chess game of the global economy, changes are quietly staged, the US debt problem is hard to return, geopolitical events are frequent, and the supranational sovereign credit value of gold under the new paradigm will constitute the medium and long-term investment logic.

　　Historically, the emergence of every round of gold bull market is inseparable from the strength of the gold currency attribute, which reflects the changing forces of all parties in the international monetary system.

　　According to the data released by the central bank on May 7, despite the recent rapid rise in international gold prices, the pace of the Bank of China’s increase in holdings has remained basically stable. At the end of April, China’s gold reserves were 72.8 million ounces, compared with 72.74 million ounces at the end of March. This is the people since October 2022.For the 18th consecutive month, it increased its holdings of gold reserves, setting the longest holding period.

　　Statistics show that at present, the proportion of gold in China’s international reserves is only 4.32%, which is still far below the global average of about 14%. The proportion of gold reserves in the United States, Germany, Italy and other countries in the same period is over 65%, so there is still room for improvement in the future. (Source: World Gold Council; Publicly reported)

　　From this point of view, the participants in the short-term gold game seem to face a strong opponent, which makes investors who try to play short-term gold games seem unwise and difficult to win.

　　On the other hand, after the rise, the return risk characteristics of gold itself have not changed, and the low correlation with other assets still exists, which ensures that the value of gold in the allocation of large assets is still outstanding.

　　In recent 20 years, the correlation coefficient between gold and other common large-scale assets is less than 80%, and the correlation coefficient between gold and the main indexes of A-share market is less than 50%:

　　The trend of dollar gold and Shanghai gold is highly consistent: the correlation coefficient between SHFE gold and COMEX gold is as high as 0.98 in recent 20 years. Although Shanghai gold is affected by the exchange rate of RMB against the US dollar, from the perspective of long-term allocation, the trend of the two is highly consistent;

　　The correlation between gold and A shares is low: gold and CSI 300,Most of the correlation coefficients are within 0.5, and those with equity funds and hybrid funds are within 0.7. (Source:Institute)

　　Taking the most common equal weight strategy as an example, we observe the effect of moderately increasing the gold allocation in the allocation of 28-share debt and 64-share debt respectively.

　　The calculation shows that moderately increasing gold allocation in the allocation of 28-share debt and 64-share debt can achieve a better strategy of increasing income and reducing risk at the same time.

　　In the benchmark strategy of 2:8 ratio of stocks and bonds, if 10% of funds are removed from bond assets and 5% from stock assets, the average annualized rate of return will increase by 0.69 percentage points, the maximum withdrawal will decrease by 1.97 percentage points, the annualized volatility will decrease by 0.38 percentage points, and the annualized Sharp rate will increase by 0.199.

　　On the benchmark strategy of 6:4 ratio of stocks and bonds, if 15% of funds are removed from bond assets and 5% from stock assets, the average annualized rate of return will increase by 1.11 percentage points, the maximum withdrawal will decrease by 1.57 percentage points, the annualized volatility will decrease by 0.71 percentage points, and the annualized Sharp rate will increase by 0.091. (Source: Institute)

　　On the other hand, this forever shiningNo one can predict how long its history will develop. However, the history of gold over thousands of years makes people reasonably believe that future generations will also be fascinated by gold.

　　How to allocate gold? Physical gold has always been regarded as a "safe haven", which is more suitable for investors who pursue a sense of security and long-term value storage, but it needs to be carefully stored to prevent its value from being affected by wear and tear.

　　In contrast, gold-related theme funds, such as gold stock ETF or gold ETF, provide a more convenient choice for market transactions, but when the market is hot, it is also necessary to maintain the principle of rational investment and avoid paying for high premiums.

　　However, no matter which variety you choose, you must pay attention to the position control when allocating gold. Gold is more suitable as a part of asset allocation rather than a heavy position or a single layout, and the usual position ratio is 5-10%.

　　As far as the current gold investment is concerned, perhaps the answer before investors is this:Moderately downplay the short-term trading value of gold, look for the opportunity to point gold in the shock, and explore the gold value in asset allocation from the perspective of long-term allocation.

Since March, the price of gold has continued to rise, setting a new record! The domestic gold price once appeared "overnight soaring". After accumulating a large increase, recently, the international gold price fluctuated at a high level, and the gold price that had previously maintained an upward trend sat on a "roller coaster".

How to rationally allocate limited assets in the gold market and make sustained profits has become an urgent problem for investors.

The price of gold suffered a major decline after the peak.

On April 12, local time, Loco London gold rose all the way in the morning, rising nearly 2.5% in intraday trading, but then plunged sharply, which not only retreated all the gains of the day, but also finally closed with a decline of 1.25%, with a retreat of nearly 4% in the day; Futures prices also followed the spot price out of a similar market. COMEX gold futures once rose more than 3% in intraday trading and finally closed down 0.53% at $2,360.2 per ounce.

Affected by the high diving of the international gold price, the increase of Shanghai Gold also narrowed on the night of April 12, and it once rose more than 4% in intraday trading, and then it was adjusted back, and the increase fell back to 0.15% at the close.

On the evening of April 10th, the latest data of ——CPI (Consumer Price Index), the most critical inflation data before the Federal Reserve’s May resolution, was released. The US CPI rose by 3.5% year-on-year in March, which was higher than the market expectation of 3.4%. This figure intensifies the fear that inflation will accelerate again, which means that the possibility of the Fed cutting interest rates in June will decrease. The market’s expectation of the timing and frequency of the Fed’s interest rate cut this year has also changed to two times since September.

After the data was released, the international gold and silver prices fell briefly. However, the year-on-year growth rate of the US PPI (ex-factory price index of industrial producers) in March announced on the evening of 11th was slightly lower than expected, and the chain growth rate slowed down to 0.2%, which made gold and silver "rebel" again.

On April 12, COMEX gold reached a maximum of $2,448.8 per ounce; Spot gold in London once reached $2,431.78 per ounce, both hitting record highs.

The gold price of jewelry is almost equal to 730 yuan/gram.

High prices "persuade" consumers

For the recent rise in gold prices, many netizens have commented on "regret not getting on the bus" and "the price of gold jewelry is too high". Some netizens also said, "Now this price is just needed and I dare not buy it."

"This period of time is a price per day. Generally speaking, it is a small increase or a small increase." The sales of a gold shop in Chengdu told reporters, "The price of gold has really risen too high recently, and many consumers are waiting to see. I have served a couple who are about to get married before, bought a ring before the New Year, and recently wanted to buy earrings, bracelets and other accessories, just because the price of gold has risen too high recently, I have been hesitating."

The salesperson told reporters that if you are in a hurry to get married, you can consider platinum rings, and there has been no big price fluctuation recently.

The reporter visited several brand gold stores in Chengdu and found that the listing price of gold jewelry today is slightly lower than that of 730 yuan per gram a few days ago. At present, the prices of jewelry in gold jewelry stores of brands such as Lao Fengxiang, Chow Tai Fook and Zhou Shengsheng are mostly between 720 yuan and 728 yuan per gram. In the actual purchase process, different brand stores will give different degrees of concessions through in-store concessions, discounts and full reduction, and the final price will be between 680 yuan and 710 yuan per gram.

"The peak period of gold consumption is generally around the New Year. Now, after entering March and April, consumers’ purchasing enthusiasm has declined, and passenger flow and transactions will be less." A clerk in a gold jewelry store told reporters that the price of gold has been rising recently, and some "non-just-needed" consumers will also choose to wait and see.

Explore the reasons for the sudden drop in the price of gold

After analysis, the researchers studying financial issues in the Climate Change and Energy Transformation Project of Peking University Energy Research Institute believe that the main reasons for the current downward trend of gold prices are as follows:

First, the value of the dollar has risen. As a substitute for the reserve currency, gold has an inverse relationship with the value curve of the dollar. Recently, the value of the dollar has suddenly increased, and investors have chosen to buy a large amount of dollars and sell gold at the same time, and the price of gold has decreased accordingly.

Second, the interest rate is raised. Recently, former US Treasury Secretary LawrenceSummers said in an interview with relevant media that the public should accept the possibility of raising interest rates by the Federal Reserve, rather than lowering interest rates. Therefore, the increase of interest rate will make investors consider whether it is reasonable to continue to buy gold without interest, which will lead to a decline in their willingness to buy, and then affect the price of gold.

Third, the expected production capacity of gold ore has increased. According to the relevant data released recently by Canadian mining giant osino, its Gemini mine project in Namibia will provide its parent company Yintai Gold with a gold production capacity of not less than 5 tons/year after it is put into production. Yintai Gold expects that the total gold production will rise to 12 tons in 2025. At the same time, Zijin Mining also expects the gold production capacity to rise to 73.5 tons in 2024. It can be seen that the increase in gold production will lead to oversupply, which will lead to a decline in gold prices.

Experts believe that the particularity of gold itself determines that it has an extremely complex market environment. For investors, it is necessary to always remember not to blindly follow the trend, "chase up and stop falling", carefully analyze the reasons for the rise and fall of the value of the invested products, and make a reasonable investment plan according to their own wealth level. Only by doing what they can can be stable and lasting and be invincible in the market. (Wu Shihao)

　　High-precision images obtained by Fengyun-4 B star

　　The first one

　　It is equipped with the world’s first day and night high frequency imaging instrument.

　　First batch

　　Successfully acquired the first batch of high-precision images and data.

　　first time

　　Clearly see the minute-level wind and cloud change process with the naked eye.

　　First time

　　Realize the wish of "seeing where there is a disaster quickly"

　　The Weather Forecast broadcast on July 1st published a satellite cloud picture, which attracted the attention of many netizens. This is the first operational star of a new generation of geostationary meteorological satellites in China — — The first batch of high-precision and high-efficiency visible light observation images successfully obtained by Fengyun-4 B star.

　　On the full-disk satellite cloud image, the snow in Tianshan Mountain, the surface texture of lakes and Hetao areas in Qinghai-Tibet Plateau, convective clouds in Northeast China and North China, and vortex clouds in high latitudes in the northern and southern hemispheres are clearly visible.

　　These images can visually show the fine structure of convective clouds, and the temporal and spatial resolution is increased from 5 minutes and 500 meters to 1 minute and 250 meters respectively, which improves the continuous and rapid monitoring ability of small and medium-sized clouds, and is of great significance for the monitoring and early warning of severe convective weather, especially for the monitoring of sudden small and medium-sized weather systems.

　　Fengyun-4 b star successfully acquired

　　The first batch of high-precision images and data

　　Fengyun-4 B satellite was successfully launched on June 3, and it is the first operational satellite of the second generation geostationary meteorological satellite in China. It is mainly used in weather analysis and forecasting, environment and disaster monitoring and other fields. The satellite, which is in the on-orbit test, successfully obtained the first batch of high-precision data and image products. On the full-disk satellite cloud image, the snow in Tianshan Mountain, the surface texture of lakes and Hetao areas in Qinghai-Tibet Plateau, convective clouds in Northeast China and North China, and vortex clouds in high latitudes in the northern and southern hemispheres are clearly visible. On the panchromatic image products with a resolution of 1 minute and 250 meters and the image and animation products with a resolution of 500 meters, the fine structure and development process of convective clouds can be seen at a glance. It is worth mentioning that this product generation uses machine learning technology to realize true color atmospheric correction.

　　Carrying the world’s first

　　Day and night high frequency secondary imaging instrument

　　The fast imager carried by the satellite is the world’s first day-and-night high-frequency imaging instrument, which can provide one-minute interval multi-spectral continuous observation in an area of 2,000 km× 2,000 km, making the monitoring of typhoons, rainstorms and mesoscale disastrous weather more flexible and precise. The advanced geostationary orbit radiation imager adds the function of low-level water vapor imaging, which enhances the quantitative observation ability of the surface and clouds. The geostationary orbit radiation imager and the fast imager cooperate with each other, which not only ensures the multi-spectral effect required by geostationary orbit atmospheric remote sensing, but also has the observation ability of high temporal and spatial resolution.

　　Tang Shihao, chief designer of Fengyun Meteorological Satellite Engineering Application System, said that Fengyun-4 B-star made it possible for people to clearly see the minute-level change process with the naked eye for the first time, and also realized the wish of "seeing where there is a disaster quickly". In addition, the variety of B-star products has increased significantly, which can provide observation support for meteorological forecasting, disaster prevention and mitigation, response to climate change, and ecological civilization construction, especially for monitoring and early warning of major disasters such as typhoons, floods and droughts.

　　Data daily service capacity

　　Increase by 50%

　　Lu Feng, chief designer of the optical satellite ground system of Fengyun-4 geostationary meteorological satellite, said that in order to ensure the long-term stability of satellite observation and data, the service life of Fengyun-4 B star is 7 years. The ground application system will build a brand-new core business system to give full play to satellite benefits. The daily data processing capacity of Fengyun-4 B star is about 1.2 times that of Fengyun-4 A star, and the daily data service capacity is improved by 50%.

　　In the next step, Fengyun-4 B star will conduct a one-year on-orbit test, test and apply, and release products in batches. Fengyun-4 star B will also form a networking advantage with star A, and will be strong in key areas and important weather process monitoring to provide more abundant observation products. According to CCTV News and China Weather Network,

　　Quick and accurate reality

　　Fengyun no.4 b star

　　Three characteristics to upgrade meteorological service

　　After the launch, Fengyun-4 B star was fixed at 123.5 degrees east longitude, and joined hands with Fengyun-4 A star. The observation range reached the Indian Ocean in the west and crossed the international date line of the Pacific Ocean in the east, which not only completely covered China’s territory, but also covered a wider area such as the Northwest Pacific Ocean and Oceania, enabling China’s second-generation geostationary meteorological satellite to realize the business model of two-star operation and east-west layout.

　　Fengyun-4 B-star service will be upgraded on the basis of A-star, and a high-speed, reliable, all-weather and all-weather data processing, transmission and distribution system will be built to ensure the meteorological service of meteorological data end users and serve the national economy and people’s livelihood.

　　Fast: every second will ensure efficiency.

　　As a geostationary meteorological satellite, obtaining high time resolution observation data is the primary task of Fengyun-4 B satellite, and data processing, transmission and distribution are irreplaceable links. Therefore, as the overall unit of the satellite, 509 Institute of the Eighth Academy of Aerospace Science and Technology Group, together with users and contractors, has built a high-speed data processing, transmission and distribution system between the satellite and the ground. Using the satellite-ground high-speed data system, the B-satellite remote sensing load is sent to the earth data transmission subsystem for data processing while acquiring remote sensing data, and then transmitted to the ground station for data processing through the satellite-ground high-speed data transmission channel.

　　After being processed by the ground station, the generated meteorological products will be quickly distributed to the fixed meteorological stations at all levels in provinces, cities and counties and the vehicle-borne and ship-borne mobile receiving terminals in the satellite coverage area through the high-speed information forwarding channel and the low-speed information forwarding channel of the satellite-to-ground forwarding system. Using the satellite-ground high-speed data system, it takes only a few minutes to obtain remote sensing data from remote sensing load to reach the end users, and it can provide high-frequency meteorological data for ships in China and its surrounding areas and sea areas.

　　Accurate: data "express" to ensure quality

　　Meteorological satellites are called "the first line of defense for disaster prevention and mitigation" by the industry because the remote sensing data detected by satellites are the first-hand data for monitoring and predicting the development and trend of severe weather. Therefore, satellite remote sensing data when bad weather occurs is particularly important.

　　By adopting a number of technologies, Fengyun-4 B-star ensures that data transmission is not afraid of typhoons and rainstorms, and can be stably and reliably transmitted to ground stations, assisting meteorological units to make accurate weather forecasts and reducing the losses that bad weather may bring to national lives and property.

　　Reality: self-upgrading to protect people’s livelihood

　　In order to further improve the application efficiency of B-star as the first operational satellite of Fengyun-4 series, this time, the research team carried out a "self-upgrade" of the satellite-ground data transmission and distribution system, which really made users experience convenience and speed.

　　In order to further bring special vehicles, small and medium-sized ships and other mobile platforms into the service group of low-speed information forwarding channel, the output power of the downlink power amplifier of Fengyun-4 B-star low-speed information forwarding channel is doubled, and the antenna diameter of the ground receiving terminal is reduced by 0.3 times, which solves the problem that it is difficult to install receiving equipment on mobile platforms such as vehicles and small and medium-sized ships.

　　At the same time, in order to adapt to the application scenarios where the moving direction of mobile terminals such as vehicles and ships changes in real time, and improve the experience of data forwarding service, the research team changed the polarization direction of downlink microwave signals in the high-speed information forwarding channel and the low-speed information forwarding channel of the satellite-to-ground forwarding system from horizontal vertical double-line polarization to left-right rotation double-circle polarization, thus solving the problems of polarization isolation reduction and data reception error or interruption caused by the direction change of the receiving platform.

　　Fengyun-4 B-Star has also added a high-speed Ka-band high-speed original remote sensing data transmission channel, which supports the real-time transmission of high-speed remote sensing data to the ground when a typhoon or local disastrous weather area occurs, thus improving China’s emergency capabilities such as forecasting and monitoring disastrous weather and reducing the loss of life and property of the people of the country.

　　Zhongxin. com Sichuan News, January 4th (Liu Xiaoli) At the beginning of the new year, all enterprises in China Sichuan Cuisine Industrial City Park, Pidu District, Chengdu are busy with production, R&D, market expansion and order rush, striving to achieve a "good start" in the first quarter.

　　On January 3, the production workshop of Novomey Biotechnology Chengdu Co., Ltd. (hereinafter referred to as Novomey) was busy. In the frying workshop, 40 woks are arranged around, and the staff are monitoring all data indicators in real time in front of the electronic screen; In the packaging workshop, the equipment runs quickly, and bags of compound seasoning are off the assembly line. In the loading and unloading area, the packaged products are being loaded and will be sent to major cities soon.

　　Nuogaomei Company is a comprehensive standardized condiment customization enterprise integrating R&D, production and sales, focusing on providing catering enterprises with the overall solution of catering standardization in compound seasoning. The enterprise was built last year and put into production in October last year. Since it was put into production, it has been in busy production.

　　"Before and after the Spring Festival is the traditional peak season for consumption, and it is also the peak season for production in the food industry. Our company’s philosophy is’ everything must serve customers’, so we are working hard to ensure the delivery of orders. " Ni Taoyuan, the production director of Novomey, said that at present, there are enough orders from enterprises. In order to ensure delivery, the frying workshop runs 24 hours a day, and the staff takes two shifts and all 40 woks run. "The frying workshop can guarantee the delivery of 200 tons of fried materials every day, and the whole factory can deliver 300 to 400 tons every day."

　　According to reports, as a professional service provider providing compound seasoning for chain catering brands, Nogo Beauty Company has been quietly appearing beside consumers. Everyone’s familiar delicacies, such as Man Xiaobao, Shu Daxia, Mao Daxian, Laoxiang Chicken, Wuliguan Hot Pot, Limestone Roast Chicken, and Laojie Weigan String, are all inseparable from Nuogaomei.

　　"We will use Nogomel as the company headquarters, and at the same time, we will transfer the production capacity of the company in other regions to China Sichuan Food Industry City." The person in charge of the company said that through the creation of smart factories, we will strive to achieve new breakthroughs in output value.

　　Not far from Nogaomei Company, Sichuan Dandan Pixian Douban Group Co., Ltd. (hereinafter referred to as Dandan Group) Sichuan Road Factory is also busy, and the workers cooperate closely with each other to make orders and sprint for a "good start".

　　"At present, there are still many orders, and we are in a hurry. Roughly speaking, from New Year’s Day to Spring Festival, we need to deliver orders of more than 80 million yuan. At present, we are working at full capacity and working overtime to ensure market supply before the holiday. " Yue Yisong, Marketing Director of Dandan Group, said.

　　According to reports, the Sichuan Road Factory of Dandan Group has been running well since it was put into production, and its production capacity has been fully released. However, it is still far from meeting the market demand. Yue Yisong introduced that in order to solve the problem of tight production capacity, in early 2023, the company built a new production workshop in Yong ‘an Road Factory. It is expected that this workshop will be put into use in 2024, which will alleviate the problem of supply capacity to some extent.

　　In 2023, Dandan Group shouldered the market pressure, strove forward and operated steadily, and achieved a booming production and sales. The annual sales revenue exceeded 800 million yuan, up more than 15% year-on-year. Yue Yisong said that in 2024, Dandan Group will, as always, do a good job in products and services, continue intensive cultivation to expand the market, increase the application and promotion of Pixian watercress in various cuisines, and intensify brand promotion, so as to make a good start for Dandan Group’s journey towards 1 billion yuan. (End)

　　In 2020, the Ministry of Agriculture and Rural Affairs and the Central Network Information Office officially released the Digital Agriculture and Rural Development Plan (2019-2025). Digital agriculture in a broad sense includes four dimensions: agricultural Internet of Things, agricultural big data, precision agriculture and smart agriculture. It includes a complete system of data collection, classification, application and mining, serving the whole process of agriculture.

　　As the capital, Beijing has gathered the best talents and advanced technology and equipment in the country, and has a number of national scientific research institutes and laboratories, which have made solid research and promotion in 3S technology, precision farming technology, agricultural information management, agricultural biological environment control and automation.

　　Many modern agricultural industrial parks have already begun to lay out digital agriculture, taking information as an agricultural production factor, and using technologies such as big data, Internet of Things, artificial intelligence, blockchain, and 5G to visually express, digitally design, and informatize agricultural objects, environments, and the whole process. Today, we walked into the modern agricultural park around us to explore the current situation of its digital agriculture development and get a glimpse of its future.

　　A multi-span greenhouse and 13 digital technologies

　　In the 5G era, what are strawberries growing in the clouds? How does it taste? How is the output? What is the cost? With such doubts and curiosity, the reporter went to the "strawberry in the air" multi-span greenhouse in Zhongguancun Science Farm of Haidian Agricultural and Rural Bureau.

　　Pushing through the door, a large display screen at the door can clearly see the top window, sunshade net, top quilt, two-layer film, thermal insulation quilt, crosswind, fill light, tidal irrigation … which show the latest situation of strawberry planting in the shed in real time.

　　Through the glass door, I saw an intelligent robot spraying water and fertilizer automatically. Rows of bright strawberries hung in the air, and the ground was spacious and clean …

　　If you want to enter the greenhouse, you must have a strict disinfection process, put on your shoes, and walk into the closed air shower spraying room before you can enter.

　　Just entering the shed, the faint fragrance in the air came to my face, and the fruit was bright red and attractive on the rows of strawberry verandahs. I can’t help but pick one to taste, sweet and soft, and my mouth is full of fragrance. "This is Xiangye, which is what everyone calls Sui Zhu." Zheng He of Haidian District Agricultural Technology Comprehensive Service Center introduced. "5G cloud strawberry is independently developed by Beijing Haidian Agricultural Science Research Institute, which integrates and optimizes 13 technologies, including 5G communication platform, artificial intelligent robot, organic standard green prevention and control, greenhouse intelligent control system, multi-layer covering insulation, intelligent water and fertilizer integration technology, substrate heating system, low-temperature cold storage seedling application, spray cooling system, plant LED light supplement, tidal irrigation technology, nutrient solution recovery system and axial fan temperature equalization system."

　　"With the blessing of a number of technologies, the strawberry market in the shed is advanced by more than 20 days, and the fruit-setting period is extended. The yield per mu can reach more than 6,000 kilograms, an increase of 20%-50%, and the income per mu is more than 60,000 yuan, which is significant in improving quality and increasing efficiency." Zheng He added.

　　How to advance the listing period by more than 20 days? First, it relies on low-temperature cold storage seedling raising technology, which uses the cold climate in alpine areas to cultivate high-quality strawberry seedlings and break the sleep period of strawberries in advance, so as to advance the fruit-bearing period. Second, it depends on the application of substrate heating system, which can realize accurate temperature control of all-weather substrate. Third, plant LED fill light technology can effectively inhibit strawberry dormancy, promote photosynthesis, shorten the growth cycle, and advance the time to market.

　　The extension of fruit-setting period depends on equipment such as spray cooling system and sunshade net, which provide the best temperature environment for strawberry in the later growth stage. The improvement of fruit setting rate and quality comes from the application of greenhouse intelligent control system, intelligent water and fertilizer integration technology and axial fan temperature equalization system, which provide strawberry plants with accurate growth environment, nutrients, water and fertilizer, CO2 concentration and so on.

　　It is reported that this is a brand-new concept of strawberry cultivation, soilless cultivation and aerial cultivation. It is not only a brand-new agricultural production mode, but also broadens the application scope of agricultural production, which is a beneficial attempt and exploration of agricultural versatility. "We will continue to deepen digital agriculture, deeply integrate agriculture with science and technology, open up new ideas for agricultural development, and continue to show the style of’ Zhongguancun in agriculture’." Zhang Chunming, secretary of the Agriculture Working Committee of Haidian District Committee and director of the Agriculture and Rural Affairs Bureau, said.

　　When fully localized intelligent equipment is applied in multi-span greenhouses

　　As soon as I walked into Beijing Chaolai Agronomy Garden, the strong smell of tomato seedlings overflowed the whole greenhouse.

　　"Are all tomatoes planted in this shed?"

　　"hello! Welcome to the multi-span greenhouse in Chaolai Agronomy Garden. At present, tomatoes are planted in this area, and there will be melons and cucumbers in the next year … "Before Wang Jiangao, who accompanied him, spoke, the intelligent voice reception robot in front of him began to explain. At present, it is a working robot spraying pesticides on the working track, which will make you feel as if you are in a scientific research laboratory, not a greenhouse. On the side of the central controller, the present situation in the shed, the situation in the production area, when to fill the light, when to increase the temperature, open the internal insulation, ventilation and so on are clearly displayed.

　　"This is the equipment terminal for workers’ daily inspection, which clearly records the running log, production situation and farming situation." The technician introduced. "Environmental control carries out intelligent control of light, temperature, moisture, humidity and fertilizer in greenhouse, which on the one hand reduces the incidence of pests and diseases and improves the quality and quality of protected vegetables. On the other hand, it can also reduce labor costs, realize 7×24 hours of intelligent control, and ensure the whole process of supervision from the field to the tip of the tongue. "

　　It is understood that this multi-span greenhouse, from intelligent seedlings, to Internet of Things sensors, to water and fertilizer irrigation systems, pest control, as well as blockchain traceability, harvesting, sorting and packaging, etc., uses domestic intelligent equipment in all aspects, realizing the integration of domestic Internet of Things, cloud computing, data processing, AI control and other technologies. Therefore, it has become the first demonstration site of integrated application of intelligent equipment in multi-span greenhouses in Beijing. "It not only solves the problem that domestic efficient facilities, equipment and technology are constrained by foreign countries, but also realizes localized and personalized development and management, making the system more open and inclusive. In addition, the cost of domestic intelligent equipment is very low, which is 50% lower than that of foreign countries, and the subsequent operation and maintenance management is even more guaranteed. " The technician said proudly.

　　In addition, Chaolai Agronomy Garden not only introduced all kinds of high-tech information technologies, but also introduced high-efficiency cultivation technology systems such as coconut chaff substrate cultivation and hydroponics, which changed the previous single demonstration mode of information technology, realized the integration and application demonstration of information technology and high-efficiency agronomy technology, gave full play to the fusion effect of information technology, and effectively improved the production management level of facility agriculture park.

　　It is reported that Beijing Chaolai Agronomy Garden was established in 1996, covering an area of more than 200 mu, with one multi-span greenhouse and 19 solar greenhouses. It is one of the two pilot parks of Chaoyang District National Digital Agriculture Innovation and Application Base.

　　Obviously, the application of digital technology can make the agricultural park realize the optimal allocation of production factors such as land, facilities and labor based on the microclimate environmental control and water and fertilizer integration technology of the Internet of Things, the agricultural product quality traceability system of the blockchain, the intelligent agricultural machinery technology of computer vision, the agricultural management system software, etc., and form a modern agricultural model of "planting brains, growing intelligently and tracing sales", creating a new future agricultural model with strong reproducibility.

　　Digital agriculture is connected with science and technology at one end and agriculture at the other. From physical strength to intelligence, from "relying on experience" to "relying on data", the development direction of intelligent science and technology answers the necessary question of agricultural and rural modernization. In recent years, Beijing’s agricultural and rural informatization construction has been steadily promoted, and the development mode and path of regional agricultural and rural informatization have been continuously explored, which is in a critical period of development and has gradually formed Beijing’s advantages and regional construction characteristics, and the future is expected.

Special feature of 1905 film network 　As a true fan, after waiting for 5 years, the sequel of this series (hereinafter referred to as "Pacific Rim 2") was finally released!

We must know that the birth process of this film can really be described as twists and turns: first, the producer Universal Pictures worried that the market performance was repeatedly delayed, which indirectly led to the former director "Gyro" retreating to the second line due to work conflicts, and then Legendary Pictures decided to enter the game, but it experienced a wave of turmoil acquired by Wanda Pictures … … The whole project has been tested on the edge of "premature death" many times, and it is simply scary to see this powder.

This tense mood continued until I finally walked into the cinema to watch "Pacific Rim 2". After all, the man at the helm has changed from "the famous monster iron powder" and "the senior otaku" guillermo del toro to Steven S. DeKnight who directed the first large-scale commercial film. Can the latter really Hold the "Pacific Rim" series? Such doubts have always existed since the first day he took over the project.

In fact, like "Gyro", Steven is also a fan of Japanese anime, special films and monster movies. According to the theory of "dimension", the two people’s preferences are not far apart. However, the image style of "Pacific Rim 2" finally presented on the screen is quite different.

Friends who have seen the previous film should still be deeply impressed. Just like the Oscar-winning film "Top" recently landed in the mainland cinema, the first episode of "Pacific Rim" is also quite "dark" and "metal punk". In the movie, the main character of the mecha, "Dangerous Wanderer", and the monster Kaiju both played in the dark rainy night. Whether it is the naval battle in Alaska or the peak confrontation between Hong Kong port and city center, there are basically two or three lights (searchlights and neon lights), and it keeps raining.

If you don’t think about it carefully, you may think that this special effect of black paint is to save money. But if you look at the production costs of Pacific Rim and Pacific Rim 2, you will find that the former actually cost nearly 300 million yuan more. )

For a film featuring the mecha, the choice of the texture of the mecha will also directly affect the overall style of the film. The "dangerous vagrants" in the first episode of Pacific Rim, including the supporting roles "Storm Red", Cherno Alfa "Tank" and Eureka "Raider", all highlighted the heavy metal sense, mechanical sense and even a sense of weight of the mecha to the greatest extent. This is also an important reason why Pacific Rim is the most different from other works of the same type and is highly sought after by hardcore sci-fi fans.

In michael bay, when the alien car people have been able to fly and roll in the fight flexibly, the "gyro" mecha are still walking at a step-by-step pace, and each punch that they swing slowly and firmly seems to really weigh a thousand tons. In terms of screen selection, Pacific Rim also repeatedly emphasizes the luster of the unique texture of metal and the shocking magnitude of the mainframe armor by giving more "close-ups" to the mecha, such as the cockpit and internal parts, and the special weapons and equipment used by each fighter, including the impact of the mechanical arm with the monster’s body and buildings during fighting.

Steven, as a baton receiver, once mentioned in an interview that he appreciates the style of "top" very much, and the monster world he created always reminds him of the works of H.P. Lovecraft, a famous American classical horror story writer in the last century. For the first episode of "Pacific Rim", Steven was also most impressed by the dark, humid and cold atmosphere in the film. But when he became the leader, he didn’t want to repeat this route, but hoped to bring a completely different sequel to the audience.

[The following involves spoilers]

One of the few heavy action scenes in the film took place in Sydney (clear sky), Siberia (snow-capped) and Tokyo (sunny). This shows Steven and the whole crew’s confidence in the production of special effects: when the light is sufficient and the vision is clear, every detail of the object will be presented to the audience 100%, so a little omission will be easily caught. The behind-the-scenes team of "Pacific Rim 2" really worked hard in this part.

Unlike the previous film, which was simply about monsters, this time director Steven joined the battle between the mecha according to the needs of the plot development, and the film once looked very much like "Pacific Rim: Transformers". However, compared with Kaiju’s "Tokyo War" in the second half, it is actually wonderful to recall the two encounters between the revenge wanderer and the villain "Obsidian" in Sydney and Siberia (at least the mech’s sense of mechanical strength can be perfectly displayed).

Choosing to place the final battle of Pacific Rim 2 in Tokyo is Steven’s absolute selfishness as a "Japanese anime fan". When he was young, he grew up watching Altman, Lava Ambassador and other works, and he had no resistance to "smashing" a city in the decisive battle. So when the four main mecha — — Revenge wanderer, Phoenix Guerrilla, Saber Athena, and Redeemer Titan went into battle collectively in the Tokyo team battle, making different killing skills against three high-level Kaiju. The appearance of this game really made up for the regret that there was no "team battle" in the previous work "Pacific Rim".

However, even though the huge steel warrior and the giant monster who finally realized the "three-in-one" shuttled and fought among the high-rise buildings, the screen seemed to be full of the shadow of "the special film of Altman shooting small monsters that we chased together in those years", but frankly speaking, this scene of "Pacific Rim 2" is just a completely superficial copy of "tribute" to the mecha department and the monster film. The so-called "clear at a glance" bright special effect, on the contrary, adds a strong "plastic feeling" to the whole scene because it cannot highlight the light and shadow changes of the metallic luster on the surface of the mecha.

The "mech feelings" once conveyed by the dark, cold and metallic pictures in Pacific Rim, as well as the desolation and weight sense of the mech soldiers in the doomsday war, have disappeared in the sequel. For the audience who know this series for the first time, perhaps "Pacific Rim 2" is another Hollywood sci-fi blockbuster they saw when they walked into the cinema, which is nothing unusual. But for fans who like the previous work, director Steven may subvert all the valuable cores in a work.

At present, the rating of "Pacific Rim: Thunder Comes Again" on Douban Platform has fallen below the passing line, and the rating of the audience on the ticketing platform is only 7.6, both lower than the previous work "Pacific Rim", which is exactly the same as the performance of the film after its release in North America.

At that time, it was pointed out that the simple and rude plot was the only obvious shortcoming of "Pacific Rim", and "Pacific Rim 2", which devoted its energy to "upgrading" in this respect, proved by facts that it was also wrong to blindly add a large number of new characters’ story lines and describe the protagonist’s growth experience in a large space.

For the third film of Pacific Rim, which has been quietly foreshadowed at the end of the film, I hope the director can carefully consider the correct positioning of "Mecha movies": the development of human character plots can only increase the visibility of the film if it is closely related to the synchronous growth of Mecha. Of course, if the finished "Gyro" is willing to come back and continue to take over the "Pacific Rim" series, then things may be simpler.

　　On one side is seawater, which is freezing cold; On one side is the flame, and the enthusiasm is pressing … On the gorgeous stage, Rene Liu makes people feel again and again that sadness and happiness are just the distance between the lines.

　　Two and a half hours is neither too long nor too short, but it is enough to make the fans on the scene feel like riding a roller coaster, swaying between sadness and happiness. The "culprit" of all this is naturally Rene Liu. No matter whether it is a bitter love song or a cold joke, it is so easy to put away.

　　There were many guests from Jonathan Lee, Li Xinjie, Zhang Zhenyue, Wu Bai and David, but Bobby Chen, the "he" with milk tea, didn’t show up. Therefore, even if Zhang Zhenyue plays drums and Wu Bai plays guitar, Rene Liu’s "One Night in Beijing" seems to be missing something.
