The third stage of the Great Western Front Plan has been completed.

The first phase of the project makes the annual water diversion reach 654.38+0.8 billion cubic meters. The linear distance from Shuotan to the Yellow River construction line is 1.076km, and the actual flow is 1.239km (the total length of the main tunnel is 23 1km, and the rest 1.008km is the reservoir area constructed by natural rivers, including the extension of the reservoir area of water conveyance project). The total drop is1.89m, and the average slope is 1.52. The Yellow River is introduced completely by gravity, with an annual water intake of 65.438+0.28 billion cubic meters, ensuring that the annual water inflow into the Yellow River is not less than 65.438+0.00 billion cubic meters, with an investment of 65.438+0.25 billion yuan (at the price in 2004), and only 20,000 immigrants, with a construction period of 5.

The second phase of the project makes the annual water diversion reach 200.6 billion cubic meters. The investment of the project is 654.38+000 billion yuan (mainly for increasing water diversion), which is regulated by Erhai Lake (a large freshwater lake) near Qinghai Lake, so that the hidden water will flow into Xinjiang, and the China desert greening project will be started in an all-round way, increasing 600 million mu of grain fields and solving the problem of feeding 600 million people.

The third phase of the project makes the annual water diversion reach 380 billion cubic meters. Start the second cascade project of Daxi Line, also known as the second-line project. From the east of the Yarlung Zangbo River bend, along the contour line of 2200 ~1000 meters, all the rivers in Tibetan areas, Nanpanjiang River (the upper reaches of the Pearl River) and the main tributaries of the Yangtze River join the Zuli River in Dingxi, Gansu Province, and join the Yellow River ... This project mainly intercepts the floods of the Yangtze River and the Pearl River, and transfers water180 billion cubic meters annually (basically solved) to divert some water from the Yellow River to the main stream north of the Yellow River. Connect the major rivers in China, complement each other, and implement the national water resources general dispatching, thus completely solving the water problem in China. At this point, the total water volume of the Daxi Line north diversion reaches 380 billion cubic meters per year, and the annual power generation is 1 trillion kWh; Greening desert 65.438+0 billion mu to create the south of the north; 80 million people are employed; The annual GDP growth of 29 trillion yuan has greatly enhanced China's comprehensive national strength, making the western part of China a strategic rear to support the whole Chinese nation to resist any international storms.
