新安江水电站水库迄今已运行25年,但随着水库运用年限的增长,水库淤积逐年增加,库容相应减少,缩短了水库寿命。长此以往,将直接影响水库的正常运行和经济效益。因此人们对新安江建库后的泥沙动态情况十分关注,本文就此问题提出粗浅见解,供探讨。一、水土流失成倍增加,洪水期库水浑浊新安江水库位于皖南浙北西部山区。电站于1957年4月动工兴建,至1959年9月截流
The reservoir of Xin’anjiang Hydropower Station has been in operation for 25 years so far. However, with the increase of the service life of reservoirs, the siltation of reservoirs has increased year by year, correspondingly reducing the storage capacity and shortening the reservoir life. Over time, it will directly affect the normal operation of reservoirs and economic benefits. Therefore, people are very concerned about the sediment dynamics after the construction of Xin’anjiang River reservoir. This article puts forward some superficial opinions on this issue for discussion. First, the soil and water loss doubled and the reservoir water was turbid during the flood period. The Xin’anjiang Reservoir is located in the mountainous areas in western part of southern Zhejiang, southern Zhejiang. The power station was started construction in April 1957 and intercepted by September 1959
