水是生命之源、生产之要、生态之基。随着北方地区经济社会发展和城市化步伐加快,水资源短缺形势日益严峻,南水北调工程是当前解决北方水资源短缺问题的可行之路、必由之路。我国水资源短缺,人均水资源量为2100立方米,只有世界人均水平的约1/4,且时空分布不均,南方水多,北方水少。黄淮海流域是我国水资源承载能力与经济社会发展矛盾最为突出的地区,人均水资源量462立方米,仅为全国平均水平的21%,其中京津两
Water is the source of life, production, ecological basis. With the accelerating economic and social development and urbanization in the northern region, the water shortage situation is becoming more and more serious. The South-to-North Water Diversion Project is the only way to solve the current water shortage problem in northern China. China has a shortage of water resources and an average per capita water resource of 2,100 cubic meters. It is only about 1/4 of the world average, with uneven distribution in time and space. There is ample water in the south and less water in the north. The Huang-Huai-Hai basin is the area where the contradiction between the carrying capacity of water resources and economic and social development is most prominent. The per-capita water resources amount to 462 cubic meters, only 21% of the national average. Among them,
