三峡水库大宁河调水方案研究

作为南水北调中线工程的主要水源地,汉江水资源将难以满足日益增长的调水需求,迫切需要从长江干流引水作为补充。分析了南水北调中线工程后期需调水量和调水过程。对大宁河剪刀峡水库和三峡水库的调水量和调水规模进行了研究,并且给出了最终的调水工程布置方案。该方案可充分利用大宁河水资源、减少抽水费用、占地少且对环境影响小。

Study on diversion scheme by Daning River water from TGP Reservoir

As the major water source of Middle Route Project of South to North Water Diversion,the water resources of Hanjiang River can not meet the increasing water demand and the water diversion from Yangtze River is needed as a supplement in future.The water demand and water diversion process of Middle Route Project of South to North Water Diversion in the later period are analyzed.The water diversion amount from TGP and Jiandaoxia Reservoir are studied and the final layout scheme of diversion project is given.The proposed scheme can fully use the water resources of Daning River,reduce the cost of water pumping and land occupation,and bring smaller influence to the environment.
