水资源供需矛盾日益突出,我国华北、西北地区缺水情况尤为严重。水资源尚无有效的替代措施,南水北调势在必行。从长江调水北上,曾对东、中、西三条线路从不同角度进行了研究。文中仅介绍了西线调水的方案设想、效益估算以及当地自然条件与经济水平对工程的影响。 The contradiction between supply and demand of water resources has become increasingly prominent. The situation of water shortage in North China and Northwest China is particularly serious. Water resources there is no effective alternative measures, South Water Diversion is imperative. From the Yangtze River water transfer north, East, Central and Western routes from different angles were studied. The article only introduces the concept of water transfer in the west line, the benefit estimation and the impact of local natural conditions and economic level on the project.
