利用东线南水北调工程治理黄河

Harnessing the Yellow River by East Route of Water Transfer Project from South to North

将黄河下游治理成窄深河槽,能输送高含沙洪水,进而解决防洪问题,是国家"上拦"治黄战略的完善。利用东线南水北调工程向黄河增水,促使窄河道河床冲刷下切,以形成宽河道溯源冲刷。调整南四湖流域以泄为主的水利体系,实行蓄泄结合,促进东线引江淮汛期水优化,使增水刷黄有了水源。小浪底水库拦沙期泄水冲刷,东线南水北调工程通过东平湖向黄河增水冲刷,两种冲刷共同作用,给黄河治理带来了难得的机遇。

Training the lower Yellow River into a river of narrow and deep channel can deliver hyper-sediment concentration floods, solve the issue of flood control and perfect the state strategy of ”retaining at upper stream” of the Yellow River management. To increase the water volume of the Yellow River by the east route of Water Transfer Project from South to North and impel scouring and undercutting the narrow channel for forming backscour in wide channel. To regulate Nansihu basin which takes sluicing as the main, conduct combination of storing and sluicing, promote water optimization in flood season of the east route by diverting water from the Yangtze River and Huai River and provide water source for scouring the Yellow River. The common action of the following two scours of releasing and scouring in sediment retaining period of the Xiaolangdi Reservoir and diverting water for scouring from Dongping Lake to the Yellow River by the east route of Water Transfer Project from South to North has brought a rare chance to the Yellow River management.
