建国以来,我国有关部门曾多次研究了从长江调水解决西北华北水资源不足的方案。其中最主要的有三条:即从长江下游调水的东线方案(长江—大运河—黄河—海河);从长江中游调水的中线方案(汉江、丹江—黄河—卫河一海河);从长江上游调水的西线方案(长江—黄河)。几年来,南水北调西线引水工程的前期工作取得了进展,经向有关领导部门汇报,一致认为:西线调水意义重大,效益显著,这一末来的大规模利用和均衡水资源工程,涉及我国国民经济发展战略,是开拓西北振兴北方经济的重要措施,势在必行。因此,建议西线南水北调列入国家“八五”重大科研项目。现仅就南水北调西线引水区资源与环境质量评价研究工作作一简单介绍。
Since the founding of the People’s Republic of China, relevant departments of our country have conducted many studies on the solution to the problem of water shortage in northwestern North China from the Yangtze River water transfer. Among them, there are three major ones: the eastern route that transfers water from the lower reaches of the Yangtze River (Yangtze River, Grand Canal, Yellow River and Haihe River), the mid-route water transfer project from the middle reaches of the Yangtze River (Hanjiang River, Danjiang River, Yellow River and Weihe River) West Route from the upper reaches of the Yangtze River (Yangtze River - Yellow River). Over the past few years, progress has been made in the preparatory work for the water diversion project along the Western Route of the South-to-North Water Diversion Project. After reporting to the relevant authorities, it is agreed that water diversion on the west route is significant and effective. This large-scale utilization and balanced water resources project in the future involves The strategy of national economic development in our country is an important measure to open up the northwestern economy in the northwest and is imperative. Therefore, it is suggested that the west route of South-North Water Diversion be included in the major “Eighth Five-Year Plan” national scientific research project. Now only on the South-North Water Diversion West water resources and environmental quality evaluation of a brief introduction.
