History, has the Middle Route of South-to-North Water Transfer Project been completed?

2014 65438+February 12 14: 32, which took more than 0 years to complete, with a total length of1432km. The Middle Route of South-to-North Water Transfer Project, a century-old project attracting worldwide attention, has been officially put into use and is expected to arrive in Beijing in 15 days. The Middle Route of South-to-North Water Transfer Project transfers water from Danjiangkou Reservoir at the junction of Henan, Hubei and Shaanxi provinces, excavates channels along the Taocha Canal in Xichuan, and flows northward into Beijing and Tianjin along the Beijing-Guangzhou Railway. The plan will be implemented in two phases, and the first phase of the central line project will be implemented ahead of schedule.

The first phase of the Central Line started construction in February 2003, with a total investment of 201300 million yuan. The total length of the water trunk line is 1432 km, with a total investment of 21300 million yuan. According to the plan, the first phase of the central line project will transfer 9.5 billion cubic meters of water annually, including 3.77 billion cubic meters in Henan Province, 3.47 billion cubic meters in Hebei Province, 65.438+0.24 billion cubic meters in Beijing and 65.438+0.20 billion cubic meters in Tianjin, covering 6.5438+09 large and medium-sized cities and more than 65.438+000 counties along the line (at the county level, it is understood that during the construction period, * * * 345,000 people were resettled in Danjiangkou Reservoir, covering an area of 65,000 people, 6 cities (towns)/kloc-0 were relocated, 609 compensation enterprises 160 were rebuilt once, and 609 cultural relics were rescued and protected.

The Middle Route of South-to-North Water Transfer Project takes water from the east bank of Danjiangkou Reservoir in Hubei Province, the largest tributary of the Yangtze River in the middle and upper reaches of the Han River, passes through Fangcheng Pass in Nanyang, the watershed between the Yangtze River Basin and the Huaihe River Basin, excavates channels along the western edge of the Tangbai River Basin and the Huanghuaihai Plain, crosses the Yellow River Tunnel in Wangcun, Xingyang City, Henan Province, and flows northward to Tuancheng Lake in the Summer Palace in Beijing along the west side of the Beijing-Guangzhou Railway.

The adjustable water volume of the middle route project is completed according to the later scale of Danjiangkou Reservoir, and the normal water level is1.70m.. Considering the development level in 2020, some compensation projects need to be done in the middle and lower reaches of the Hanjiang River to ensure the industrial and agricultural development, shipping and environmental water use in the transfer area. The average adjustable water volume for many years is141400 million cubic meters, and the average dry year is about 65.44 billion cubic meters (the guarantee rate is 75%).
