Just now, the project that costs 60 billion yuan has started

On the morning of July 7, one of the national key water conservancy projects, the South -to -North Water Diversion Middle Line introduced the river to supplement the Han Dynasty, and officially started construction at Danjiangkou City, Shiyan. The introduction of the Jiangsu and Hanfu project is the first construction project to promote the subsequent project of the South -to -North Water Diversion. It costs nearly 60 billion yuan and is expected to have a construction period of 9 years. After the project is completed, along this water pouring tunnel of about 194.8 kilometers long, the Yangtze River Water of the Yangtze River with 3.9 billion cubic meters of Yangtze River will be remitted from the Danjiangkou Dam of the Hanjiang River Estuary Dam from the Danjiangkou Dam every year.

Why build a "Yinjiang and Nourish Han" project? The distribution of water resources in my country is extremely uneven. The northern Huanghuaihai Basin occupies an important position in China's economic pattern, while the total water resources account for only 7.2 % of the country's total. The water resources carrying capacity and economic and social development are extremely prominent. In order to alleviate the contradiction between the distribution of water resources, on December 30, 2003, the construction of the first phase of the South -to -North Water Diversion Middle Line of my country started construction. By the end of 2021, the mid -line project had accumulated nearly 45 billion cubic meters of water to the north, and accumulated more than 50 rivers in the north for more than 7 billion cubic meters of ecological water replenishment, and more than 79 million people benefited. The economic and social benefits were significant. The South -to -North Water Tune relieved the pressure of water use in the northern water area, but it also brought the Danjiangkou Reservoir's water source guarantee rate continued to decline. When it encountered the incense of the Hanjiang River, the amount of water from the reservoir was small, which directly affected the life, agriculture and industrial water in the lower reaches of the Hanjiang River. Yu Qihui, deputy chief engineer of the Yangtze River Committee, introduced: "The upper reaches of the Hanjiang River is also being built, and water must be stored. The high -quality development of our Han River Basin also needs water. Han, supplement the Han River water resources to ensure that the first phase of the South Water and North Diversion Middle Line Project continues to exert its benefits. "

The three gorge of the Three Gorges Reservoir of the River Supplement of the Han Dynasty is the "large water tank" of the Yangtze River Basin. The total library capacity is 45 billion cubic meters, and the water volume is abundant and stable. Effectively improve the Hanjiang water resources conditions. The promotion of the Han Dynasty and the Han Dynasty connected the Yangtze River, the Hanjiang River Basin, and the Beijing -Tianjin -Hebei and Henan regions, improved the national backbone water network pattern, and greatly increased the amount of water -oriented water. The significant improvement of stability has also enhanced the ability to allocate water resources in the middle and lower reaches of the Han River.
