　　Chongqing Liangjiang New District, a State-level New District along the Yangtze River: "Half Mountain and Half City" Writing Green Development Road

　　Zhongxin. com, Chongqing, May 15 (Reporter Han Lu) The water of the Yangtze River has given birth to life and civilization along the river. In the 679 kilometers that the Yangtze River flows through Chongqing, there is a shining "star" — Following Shanghai Pudong New Area and Tianjin Binhai New Area, Chongqing Liangjiang New Area is the third national development and opening-up area in China approved by the State Council.

　　On the 14th, the second day of the "Beautiful China Yangtze River Tour Chongqing Station" activity, the delegation came to Liangjiang New District in Chongqing. Liangjiang New Area focuses on green smart cars, emerging electronic information and high-end equipment manufacturing. Here, a number of high-tech enterprises with environmental protection are stationed.

　　"Ecological civilization construction is the key work of Liangjiang New Area. From production to life, all development and construction must adhere to ecological priority, eliminate pollution from the source, and once the plan is formulated, it must be unswervingly implemented to the end." The relevant person in charge of the Management Committee of Liangjiang New Area told the reporter that in recent years, Liangjiang New Area has completed more than 10 professional plans, achieved full coverage of the plans, and delineated the blue line, green line and ecological red line, providing a basic guarantee for protecting the mountains and water in Liangjiang New Area.

　　On the same day, the reporter walked into the China Automotive Engineering Research Institute and Huaneng Liangjiang Gas Engine Factory in Liangjiang New Area to explore the green development road of Liangjiang New Area.

　　Cars have already "entered the homes of ordinary people". With the consumers’ demands for automobile safety, intelligence, comfort and health, it is getting higher and higher.

　　"Noise, vibration and safety can be said to be a concentrated expression of the quality of passenger cars." The person in charge of the State Key Laboratory of Automobile Noise, Vibration and Safety Technology of China Automotive Engineering Research Institute said that as the technical shortcoming with the biggest gap between independent brands and foreign brands, automobile noise, vibration and safety are also the most concerned and easily perceived performance of consumers.

　　According to the person in charge, the State Key Laboratory of Automobile Noise, Vibration and Safety Technology, which belongs to China General Technology Group China Automotive Engineering Research Institute Co., Ltd., was established with the approval of the Ministry of Science and Technology in 2010. It is the only state key laboratory of automobile enterprises in the Yangtze River Economic Belt. Since its establishment eight years ago, the laboratory has focused on three aspects: automobile noise and vibration, automobile active and passive safety and automobile electronic control.

　　According to reports, as far as scientific research conditions are concerned, the laboratory currently has the research and development conditions that reach the level of international first-class scientific research bases, and the related scientific research equipment and instruments reach 400 million yuan. Among them, the semi-anechoic room, full anechoic room, abnormal sound laboratory, multi-angle vehicle collision laboratory, trolley collision laboratory, crash dummy, 10m anechoic room and intelligent networked vehicle test demonstration area have reached the international advanced and domestic leading level.

　　In the research of automobile passive safety technology in the laboratory, we not only focus on the research of common technologies in the field of automobile passive safety, but also provide a complete set of star-rated development optimization schemes for enterprises in the development of automobile passive safety vehicles and parts. In the field of passive safety of new energy vehicles, the collision protection technology of power battery pack is put forward, which provides a systematic solution for enterprise research and development and design.

　　The person in charge of the laboratory revealed that at present, the laboratory has the world-class third-party collision test capability. It has the ability of vehicle-to-vehicle collision, real vehicle rollover test, pedestrian protection test and collision simulation test with different angles from 0 to 180.

　　On the basis of the research on automobile safety and maintainability, the laboratory also cooperated with the insurance industry across disciplines to establish and publish the "C-IASI Test and Evaluation Procedure of China Insurance".

　　In the water and soil industrial park not far from China Automotive Engineering Research Institute, a modern energy station is providing a steady stream of green power for the development of Liangjiang New District, which is Huaneng Liangjiang Gas Turbine Power Plant. Here, the definition of thermal power station is green, energy saving and environmental protection.

　　When the reporter walked into the production area, he couldn’t see the traditional chimneys, couldn’t hear the roar of machines, and all kinds of pipes like cobwebs disappeared. The clumsy feeling of traditional factories was replaced by garden-style factories.

　　According to reports, Huaneng Liangjiang Gas Turbine Power Plant has such a "beautiful" appearance, because the factory has put on a "coat" for the main buildings by transforming the appearance, which not only pursues fashion and beauty, but also has the functions of noise reduction and fire prevention; The appearance of the chimney adopts hotel-style design, which changes the hyperbolic cooling tower design of the traditional power plant, adopts mechanical ventilation tower, and is designed as an office building, with a silencing wall at the bottom, which makes the power plant "not like a power plant" & HELIP; …

　　"Our gas turbine adopts a low-nitrogen burner and simultaneously builds a denitrification device. The emissions of pollutants such as sulfur dioxide and nitrogen oxides are far below the national standards." Bao Yong, general manager of Huaneng Chongqing Liangjiang Gas Turbine Power Generation Co., Ltd., said that after calculation, for every 100 million kWh of power generated, Huaneng Liangjiang Gas Turbine Power Plant can reduce nitrogen oxides by 22.2 tons, equivalent to the annual emissions of 37,000 cars; It can reduce the emission of sulfur dioxide by 63.4 tons, equivalent to the emission of 23,000 tons of coal; Reducing carbon dioxide emissions by 51,000 tons is equivalent to reducing carbon dioxide emissions by 13.36 tons per mu of forest, which is equivalent to planting 38,000 mu of trees.

　　Liangjiang New Area has been using and exploring green energy and clean energy. Huaneng Liangjiang Gas Engine Factory is the first gas in Southwest China — The comprehensive clean energy station with steam combined cycle combined cooling, heating and power supply gives full play to the advantages of green, low carbon, cleanliness and high efficiency. The emission of sulfur dioxide, the main pollutant, is only one tenth of the national standard, and nitrogen oxides are less than half of the national standard, which has made contributions to energy conservation and emission reduction.

　　The network theme activity of "Magnificent Yellow River Tour" in Shaanxi Province kicked off on September 10th. The reporter started from Dali County, Weinan City, Shaanxi Province, and went upstream along the Yellow River Highway to see the ecological restoration and environmental protection of the Shaanxi section of the Yellow River and visit the Yellow River protection project.

　　From Yanchiwa to Bird Paradise, past lives of Chaoyi National Wetland Park in Dali, Shaanxi.

　　There is a wetland park with a total area of 1,185.3 hectares in the north of Luohe River and 5 kilometers east of the county seat in Dali County, Weinan City, Shaanxi Province, where reeds are washed away, water plants are rich and beautiful, and water and sky are the same. Here is an important part of the Yellow River ecological circle, which is mainly based on protection and restoration. It is completely closed and not open to the outside world at present.

　　Walking into the wetland park, one side is a lush expanse of reeds, and when you are in it, you can only hear the reeds "rustling sand" swinging with the wind, as if you were walking into no one’s land.

　　On the other side, it is even more rare, with more than 7,000 acres of lake "autumn waters grow together". In addition to marveling at this vast lake wetland like the sea, we should also know that it has a miserable "past life" past. It turns out that the picture of water and sky and lush water plants used to be a headache for local people.

　　What is the story from Yanchiwa to Bird Paradise?

　　It was the earliest place to produce salt, and it flourished several times, leaving a valuable salt cultural heritage for Chaoyi. After liberation, Yanchiwa wetland no longer produces salt, and there are salt pits everywhere. In 1958, a large-scale trial planting of rice was unsuccessful here. In the 1980s, ponds were dug to raise fish, but later they were abandoned due to the increase of salt content in water and the aggravation of soil salinization. Later, after investigation and appraisal by wetland experts, it was determined that it was mainly saline lake, which was not suitable for planting rice and raising fish. Therefore, it was decided to give priority to protection, and all of them were closed for dredging and replenishing water.

　　Ren Jianhe, director of the office of the Dali County Wetland Office, said that the implementation of the lake ecological restoration project began in 2012, and now 22.5 kilometers of protective fences, 1,000 mu of forest belts around the lake, bird watching platforms, docks and other supporting projects have been built, and efforts have been made to build a safe and healthy water, forest and lake life community. For better protection, the solar camera is now fully covered here, which is convenient for comprehensive monitoring.

　　You may be curious about a question, where does such a large area of water come from?

　　Ren Jianhe introduced that there are three sources: first, rainfall; second, because compared with the surrounding cultivated land, it is relatively subsidence of about 1 5 meters, and the farmland is higher than here, so the irrigation water of farmland can penetrate; third, the water from Luohui Canal is introduced. In this way, a large area of water that we see now has been formed.

　　After restoration and protection in recent years, at present, the wetland reeds are washed away and the water plants are abundant, forming a large area of water surface, providing an important wintering place and habitat for waterfowl such as resident birds, winter migratory birds and traveling birds. The living environment of wild animals and plants has been effectively restored, and the world’s endangered wild animals, flamingos and national second-class protected animals, such as wart-nosed swans, have been discovered one after another.

　　Nowadays, there are many birds here, and hundreds of species of birds inhabit the small island in the lake, which is called "Qiandao Lake" in Dali. The wetland park has a complete ecosystem, many animals and plants, and diverse vegetation community types, including 159 species of wild animals in 57 families, including swan, gray crane, red-footed falcon, heron and so on. There are 55 families and 164 species of plants, including reed, Suaeda salsa and Tamarix chinensis. It has high research value in natural landscape and historical culture such as ecology, scientific research, culture, education and leisure. The establishment of Chaoyang National Wetland Park in Dali, Shaanxi Province is of great significance for strengthening the protection of wetlands and biodiversity.

　　See how the children along the Yellow River can maintain the healthy life of the Yellow River and promote the harmony between people and water in the basin.

　　The Yellow River flows through Ningxia, Inner Mongolia, Shaanxi, Shanxi and other nine provinces, and is the boundary river between the two provinces. On the Shaanxi side of the Yellow River, the Yellow River Affairs Bureau of Shaanxi Province has a total length of 723.6 kilometers, involving Fugu, Shenmu, Jiaxian, Wubao, Suide and Qingjian in Yulin City, Shaanxi Province, Yanchuan, Yanchuan and Yichuan in Yan ‘an City, Heyang, Dali and Tongguan in hancheng city and Weinan City, with a total of four cities and twelve counties.

　　Among them, the section from the junction of Shaanxi and Mongolia to Yumenkou Bridge, commonly known as the "Dabei main stream", is 584.1 kilometers long and belongs to the alpine canyon river. Yumenkou Bridge to Tongguan Railway Bridge, commonly known as "the main stream of Xiaobei", is 132.5 kilometers long. The river in this section is wide and shallow, with scattered water and frequent swings. It is known as "Hedong in 30 years and Hexi in 30 years" in history. Tongguan Railway Bridge below to the junction of Shaanxi and Henan is Tongsan reach, which is 7.0 kilometers long and is the reach of Sanmenxia reservoir area.

　　The Yellow River has nurtured the sons and daughters of China, and every section of the Yellow River is also condensed with the careful maintenance of the sons and daughters on the shore. It is necessary to maintain the healthy life of the Yellow River and promote the harmony between people and water in the basin. Water administrative law enforcement, water administration supervision, flood control and drought relief, water resources management, engineering construction management, river management … … Must be persistent all the year round.

　　In the Yulin Engineering Office of Heyang Yellow River Section, the Yellow River flows slowly like a golden ribbon, and the swallow-winged dam guards the local people like a guardian. The willow planted on the outer layer of the dam is also part of the protection project. On the protective dike, we met the staff of Heyang River Bureau and listened to them talk about the work of river regulation.

　　Yulin Project is located in Yulin Village, Bailiang Town, Heyang County, between the 59-60 sections of Huangyu. The project was started in 1985. Ren Jinquan, chief of engineering management section of Heyang Yellow River Bureau, introduced the main functions of river regulation project to us. "It is an important local water diversion project — Donglei pumped water from the first-class station of Yellow River. "

　　Yulin project includes Yulin village protection, Yulin lower extension, Yulin lower extension and recent Yulin control and guidance upper and lower extension projects, with a total length of 4299 meters and 50 dams. Among them, Yulin’s upper extension project is 1000m long and there are 12 dams. The fortification standard is the local flood of 4000m3/s in 2020, the elevation of dam crest is 358.28m, and there are 5135 cubic meters of ready-made stones. Yulin village protection project is 797 meters long and has 8 dams. The fortification standard is to prevent the corresponding flood in Longmen Station of the Yellow River in 2005. The elevation of the dam crest is 359.68-359.41 meters, and there are 3,434 cubic meters of ready-made stones.

　　Yulin Downward Extension Project is 1002 meters long, with 12 dams. The fortification standard is to prevent the five-year flood at Longmen Station of the Yellow River in 2005. The elevation of the dam crest is 359.58-359.18 meters, and there are 2682 cubic meters of ready-made stones.

　　The continuous construction project under Yulin is 1000 meters long, with 12 dams. The fortification standard is to prevent the five-year flood of Longmen Station of the Yellow River in 2005. The elevation of the dam crest is 358.99-358.59 meters, and the existing reserve stones are 2545 cubic meters.

　　Yulin diversion downward extension project is 500 meters long, and there are 6 dams. The fortification standard is the local flood of 4000 cubic meters per second in 2020, the elevation of dam crest is 356.02 meters, and there are 2500 cubic meters of ready-made stones.

　　In the Yellow River protection project, "there is no turning back when opening the bow", we must shoulder the heavy responsibility bravely, unite as one, overcome difficulties, and effectively use the "mother river" in protection to create a symbiotic environment between man and nature and a sustainable circular ecosystem.

　　Today viewpoint

　　Aerospace gives people a special feeling of "high cold", which reminds them of advanced fighter planes and magnificent space stations that ordinary people can’t see, touch or use.

　　A few days ago, the well-known American website "GOBankingRates" took stock of 25 kinds of technologies originated from the National Aeronautics and Space Administration (NASA) in our daily life, which spread all over our "food, clothing, housing and transportation". They come from the distant sky, but they are convenient for our daily life.

　　Food: baby milk powder, freeze-dried fruit, food safety packaging.

　　At present, more than 90% of infant formula in the United States contains microalgae. It was originally the product of NASA research, the purpose of which was to test the potential use of algae as an oxygen "recycling agent" in space travel.

　　Freeze-dried fruit is a common snack. However, the purpose of NASA’s development of freeze-drying technology is to make the fruits in the Apollo mission easier to carry, and this technology can maintain 98% nutrition with 20% quality.

　　In order to ensure the safety and quality control method of space flight food development, NASA has now become a food industry standard to protect the food safety of consumers all over the world.

　　Life: memory foam mattress, scratch-resistant lenses, anti-ultraviolet sunglasses, cordless vacuum cleaner, Nike air-cushion sports shoes, space blankets, ski boots.

　　Comfortable memory foam mattress can fully fit the human body and relieve stress, which is necessary for many families. Memorable foam was not originally used to make mattresses. It was originally developed by NASA to cushion the impact of spacecraft landing on astronauts.

　　Compared with ordinary glass, scratch-resistant lenses have a longer life. In fact, the scratch-resistant coating is a "by-product" accidentally discovered by Jet Propulsion Laboratory (JPL) under NASA when researching the diamond hard coating for aerospace.

　　In 1980s, two scientists from JPL developed a kind of welding glasses, which can absorb, filter and scatter the strong light emitted during welding. Later, this technology was widely used in anti-ultraviolet sunglasses.

　　Initially, Black&Decker was ordered to develop a portable device for Apollo and Gemini missions, which was used to extract samples from below the surface of the moon. This technology has been improved to become a "cordless vacuum cleaner".

　　Nike air-cushioned sneakers use the patent of "Blow Rubber Molding" obtained by M. Frank Rudy, a former engineer of NASA. The initial application target of this technology is spacesuit.

　　The space blanket is insulated and heat-preserved, which is an essential item for survival in the wild and marathon. But it was originally developed by NASA to protect spacecraft and astronauts at low temperatures.

　　In addition, the technology used by NASA in the joints of spacesuits has been improved and used in ski boots, which improves the athletes’ control ability in skiing.

　　Home: swimming pool purification system, household heat insulation materials.

　　In order to resist the extremely low space temperature, NASA made an insulating material called "radiation barrier" from aluminized polyester. According to JPL, aluminized polyester is now used in most household insulation materials.

　　In 1960s, NASA developed an electrolytic silver iodide filter to provide clean drinking water for astronauts, and now it is widely used to purify swimming pools.

　　Travel: aircraft deicing system, precision GPS, anti-skid groove on highway, better tires.

　　According to NASA’s technology transfer plan, civil aircraft can fly in cold weather, mainly due to a thermoelectric deicing system called Thermawing developed by NASA.

　　Many mobile phones are equipped with precision GPS technology developed by JPL, and its data comes from JPL global GPS receiver network. Even if there is no wireless connection, you can still use GPS positioning on your mobile phone.

　　NASA’s Langley Research Center has developed anti-skid slot technology to prevent aircraft accidents on wet runways. Later, this technology was widely used in expressways.

　　In 1970s, Goodyear Company developed a new tire material for NASA Viking Mars probe, which was used in parachute system. This technology was later used to improve ordinary tires, increasing their life by 10,000 miles.

　　Electronic products: mobile phone camera, notebook computer, high-power solar cell, wireless headset, mouse, CAT scanner.

　　In the 1990s, NASA asked JPL scientists to make a miniature camera that can be installed on spacecraft while ensuring the quality of photography. According to JPL, one-third of mobile phone cameras now use this technology.

　　According to the Smithsonian National Air and Space Museum, "Grid Compass" is the first notebook computer in the world. It was first used in the space shuttle mission in 1983, which is one of the inventions of NASA.

　　The crystalline silicon solar cells used in the home originally came from the lightweight solar energy system developed by the Environmental Research Aircraft and Sensor Technology Alliance under NASA for electric aircraft.

　　NASA has developed wireless headphones for astronauts to facilitate their communication. Now this technology has entered thousands of households.

　　According to JPL, a NASA researcher developed a computer mouse in the 1960s, which allowed users to operate on the computer screen and made the computer more interactive.

　　JPL initially developed a CAT scanner to scan aerospace components to get advanced digital images to detect defects. Now, it has become a commonly used medical instrument.

　　Medical care: cochlear implant, invisible dental appliance, ear temperature thermometer.

　　Adam Kiser, an engineer at Kennedy Space Center, used his working experience in electronic, sound and vibration sensor systems in the space shuttle project to develop early cochlear implants by using electric pulses instead of sound amplification technology.

　　Compared with the traditional metal appliance, the invisible dental appliance is more beautiful. It is made of transparent polycrystalline alumina, which was originally developed by NASA to track heat-seeking missiles.

　　Nowadays, many parents use ear thermometer to measure the temperature of sick babies or young children. According to JPL, this thermometer adopts infrared dissection technology invented by NASA and Diatek.

　　There is always one of these 25 technologies that you have seen, touched and used. Aerospace technology can not only be used in high space, but also improve our quality of life after landing, which is one of the driving forces for human beings to explore and fly higher and farther.
