摘要
谷昌坝水库对松华坝水库起前置库作用 ,可拦截入库泥沙的 92 4 % ,入库总氮的 39 2 %和入库总磷的 83 5 %。以每年疏浚清淤 10万方计 ,除清走当年新入库泥沙和部分沉积泥沙外 ,还可清除颗粒态氮 12 6吨和颗粒态磷 144吨 。
Guchangba reservoir is in the front of Songhuaba reservoir.It can check the percent of 92.4 of the sands,the percent of 39.2 of total nitrogen and the percent of 83.5 of total phosphate to Songhuaba reservoir.If we dredge the silt of 100,000m 3 every year,we will remove the silt of this year and some silt of last years.We also will remove the particulate nitrogen(126 ton)and particulate phosphate(144 ton).It is very important to protect the water quality of Songhuaba reservoir.
