新安江水库的压咸作用初探

Discussion on Desalinity Function in Xin’anjiang Reservoir

新安江水库是浙江省境内最大的水利水电工程 ,具有多年调节功能 ,控制流域面积 10 441km2 ,其调度方式对钱塘江河口段水体的含氯度有直接的影响 ,从而影响钱塘江下游两岸尤其是杭州市的供水水质 ,本文对调整新安江水库的调度方式 ,增加压咸用水量的可能性及其产生的环境影响进行分析 .

Xin’anjiang Reservoir is the largest water conservancy and hydropower project of Zhejiang province,with multi-year regulation capability and catchment area of 10441km 2.The regulation mode has a direct impact on the chlorinity of water body at the estuary of the Qiantangjiang River,thus leading to the bad water quality on both banks of the Qiantangjiang River downstream,especially for Hangzhou .Analysis has been made on adjusting the regulation mode of Xin’anjiang Reservoir,the possibility of adding desalinity water and the promising environmental impact.
