The water in Xinjiang comes from the sky.

Xinjiang Uygur Autonomous Region, located in the northwest of China, with a total area of 6.5438+0.66 million square kilometers, is the province with the largest land area. Because it is located in the heart of Eurasia, far away from the ocean, it belongs to a typical temperate arid continental climate with little wind and rain, and the Gobi desert area accounts for more than 40%, so in many people's minds, Xinjiang is a desolate and arid barren land. Some people have always fantasized about introducing Tibetan water into Xinjiang and realizing the dream of "plugging in the south of the Yangtze River".

The territory of Xinjiang is far beyond people's imagination, and the area of the autonomous region exceeds more than 90% of the countries in the world. If we blindly deviate from reality and invest a lot of money to build a 6,000-kilometer-long "Hongqi River" project, except for diverting it to Hongyanhe and Mobei Rivers, the amount of water allocated to Xinjiang is only equivalent to the flow of two Tarim Rivers, and the role of allocating all the hidden water to the Taklimakan Desert is limited. Xinjiang is vast, sparsely populated, windy and has a large evaporation capacity. The ideal is full, but the reality is very skinny. A closed desert on the south side of Bosten Lake, the largest inland freshwater throughput lake in China, can be described as a "water tower", but the desert is still a desert and has not naturally become fertile land. Such a long-distance "Hongqi River" project crossing the Qinghai-Tibet Plateau strong earthquake area is extremely risky and not feasible! The investment in the main project is huge, and the water price will obviously deviate from the economic law, which may lead to the embarrassing situation that water is not used and no one wants to use it. Super projects should be fully scientifically demonstrated, and cannot cause irreparable losses to the country because of jubilation. The concept of "being in the south of the Yangtze River" actually comes from the cognitive deviation of the eastern farming concept. The natural resources of Xinjiang Autonomous Region are superior to those of most countries in North Africa and the Middle East, which are located in the arid desert belt in the middle latitude of the northern hemisphere. Many inland rivers originating from snow-capped mountains and plateaus in Xinjiang flow to Tarim Basin and Junggar Basin. There is groundwater under the undulating sand dunes, and many river alluvial fan oases in the rich piedmont can even rival the estuary delta in eastern China. Jiangnan can only be Jiangnan, and Xinjiang will always be Xinjiang. The "Hongqi River" cannot have earth-shaking changes. The water in Xinjiang only comes from the sky.

The topography of Xinjiang is summarized as "three mountains and two basins", which is one of the most abundant provinces in China. There is Turpan Basin below sea level in the east, Ili Valley with trumpet-shaped terrain in the west, Taklimakan Desert, the largest desert in China, in the south and Gurbantunggut Desert in the north. Snow-capped mountains stretch for thousands of miles, with many rivers and lakes, and forests, grasslands, Gobi and deserts coexist. People often say that Xinjiang is less than Ili, and we don't know the size of China or the beauty of Xinjiang. According to official data, the per capita water resources are 2.3 times of the national average, of which the surface water resources are 88.0 1 100 million cubic meters, the groundwater resources are 54.49 billion cubic meters, and the glacier area is 24,000 square kilometers, accounting for 42% of the national glacier area. The unique landform makes the climate difference between southern Xinjiang and northern Xinjiang great, and the distribution of water resources is extremely uneven. The Ili Valley and Altai region are rich in water resources, and there are more than ten rivers melted by snow and ice at the northern foot of Tianshan Mountain, nourishing contiguous oases. Most of the southern edge of Taklimakan desert in southern Xinjiang and eastern Xinjiang belong to serious water shortage and drought areas. Xinjiang's development planning should be based on conforming to nature, rational layout and economical construction, and should be treated differently.

Northern Xinjiang is rich in water resources. It is necessary to make full use of the rich water resources originating from Erqisi River in Altai Mountain, integrate more than ten rivers in the southern margin of the basin, expand the cultivated land area, provide water for production and living in pastoral areas, improve desert greening, and ensure wind power generation and oil and mining exploitation. The planned water conveyance channel mainly uses topography. Connecting the vast wasteland south of Karamay City and east of Ebinur Lake with the alluvial plain oasis; Further reclamation of the governable sandy land in the southeast of Beitun City will double the land reclamation area. Tarim basin in southern Xinjiang has a large area and a wide desert, and the available water resources are relatively small. In addition to local water diversion irrigation to expand cultivated land area, advanced agricultural water-saving irrigation technology should be actively promoted to maximize the use of existing water resources. The organic combination of solar photovoltaic power generation industry and reducing farmland evaporation aims to ensure the ecological balance of oasis and gradually promote production development. The Gobi desert belt in the eastern Xinjiang mainly transports domestic water through pipelines to protect the development of clean energy.

Altai Mountain, Tianshan Mountain, Kunlun Mountain and Karakorum Mountain in Xinjiang are all natural water towers, and ice and snow glaciers have bred more than 500 rivers. We dream of transporting water thousands of miles away from nearby, but we are far from making full use of nearby resources. The water-rich Ili River and Irtysh River in northern Xinjiang have all flowed abroad in vain. To cherish the precious water resources, we should divert water from Brzin River, a tributary of Yaoerqis in Altai Mountain, and move along the mountain to Fuyun County in the southwest, and then divert water from Kaerte River to increase the water flow, so as to become an artificial river and transport it to the agricultural reclamation area at the foot of Tianshan Mountain. The Ili Valley is abundant in rain, so you can choose to build a large reservoir at high altitude and a 70-kilometer-long river running through the North Tianshan Mountains. The highway transports Kashi River to the east of Ebinur Lake to reclaim wasteland, and connects the oasis to the south of Kuitun River. Enlarge the reservoir area at Smetas (elevation1900m) and excavate southward for about100km. Road, transport water to the southeast of Baicheng in southern Xinjiang, and through irrigation and reclamation, turn Aksu and Kuqa oases into the largest cultivated land in southern Xinjiang. Qiemo Oasis built a weir in Qierqin River to divert part of the water flow, and a new large-scale water conveyance channel was waterproof to deliver water along the highway to Ruoqiang County and other oases and highway service areas. A series of artificial lakes or reservoirs with impervious bottoms are built in oases on the edge of the desert and beside rivers in the desert season by using the flood in the snow melting season. In a word, building a large number of water conservancy facilities in northern and southern Xinjiang is to retain water, meet local production and life, and save the trouble of pumping groundwater.

A large area of Gobi desert in Xinjiang is a stumbling block to economic development and even affects the development of the whole northwest region. We see that the development and application of clean energy make it possible for remote and backward areas to catch up with modernization quickly. In order to gain freedom in nature, people should use natural science to understand, overcome and transform nature. The main reason for the bad environment in some areas of Xinjiang is not water shortage, but land desertification caused by super strong wind on land. The reason for the strong wind is that the ground air expands and becomes lighter and rises, and the near-ground air flows strongly due to the circular filling of peripheral cold air and high-altitude cold air. The great contrast between the hot air on the ground and the cold air around the Gobi desert in Xinjiang and the special terrain contributed to the windy weather. It has been reported that the surface temperature of photovoltaic panels is lower than that of the floor 1 1, and the back surface is 5.5 lower than that of the floor. Scientists believe that every global warming will lead to an obvious increase in extreme weather and rapid changes in the ecosystem, and the development of new energy has brought us great hope. Planning and building large-scale photovoltaic power generation facilities, greening in the Gobi Desert and reducing the regional surface temperature on a large scale will effectively curb the frequency and intensity of extreme windy weather. The construction of water pipes from Bosten Lake and Aragou to the east will meet the living and clean water demand of100000 industrial workers. The Gobi region in Dongjiang will become an ideal base for building ultra-large-scale automatic solar photovoltaic power stations and wind power stations, and make contributions to China's active promotion of green and low-carbon economy. In the future, "photovoltaic+breeding", "photovoltaic+grazing" and "wind+photovoltaic" will become the scenic spots that can be seen in the northwest including Xinjiang.

It is necessary to extensively carry out comprehensive disciplines and engineering research such as photovoltaic gas fields in the region, dare to be the first in the world, open up sources and reduce expenditure, and promote regional economic development. For example, designing standardized frame components of solar photovoltaic power plants and installing photovoltaic panels on them are convenient for ploughing below, which not only blocks part of sunlight, but also reduces soil evaporation, which is beneficial to crop growth, saves land and is harmonious. It is an effective measure to avoid salinization of cultivated land with large evaporation in northwest China. In view of the geographical characteristics of perennial strong wind in tuyere, a variable speed multi-blade power generation equipment is developed, and dense array is used to generate electricity to prevent wind disaster. Study the construction of wind dam and large wind power station in Dabancheng to turn harm into benefit; Establish an automatic monitoring system for regional geography, landforms, large airflow and heat sources, and curb sandstorms through manual intervention and physical intervention; Based on the natural temperature difference between northern and southern Xinjiang, desert oasis and plateau, the possibility of cooling the cities with concentrated population in southern Xinjiang by large pipeline components in dog days is studied. Explore parallel excavation along the seasonal reach of Hotan Desert to divert water, store water and provide water for secondary irrigation, which not only protects the original river ecology, but also avoids becoming groundwater prematurely and increases the amount of water flowing into Tarim River. Detect the terrain trend behind the foothills of snowy areas and optimize it manually? Roads are connected in series to form a new source of water, and new water sources are developed for water-deficient areas.

The national financial resources are still limited, and there are many places to spend money. Good steel should be used on the cutting edge, and resources should be concentrated on urgently needed projects such as scientific research, people's livelihood and national defense. Super projects like "Red Flag River" and the Large Electron Collider must be cautious again. With the trend of wet and warm in northwest China, the phenomenon of drought in the north and waterlogging in the south is reversed, and the "Hongqi River" scheme is likely to move against the trend. As long as we follow the trend, Xinjiang's resources will explode with amazing potential. Shizihe City has formed a comprehensive industrial chain of water-saving equipment production, research and development, design, construction and service around the drip irrigation technology under plastic film in the field, which has promoted industrial upgrading, saved water and land and increased production, and achieved remarkable economic benefits. With its geographical advantages and keeping pace with the development of the country's "Belt and Road", Xinjiang has great potential. The granary in the world, the high-quality cotton warehouse and the flower sea and fruit country are all in one, which is a place suitable for living, business and travel. Xinjiang is no better than Jiangnan.
