青山水库农业面源污染负荷预测研究

国外开发的非点源污染模型软件对输入资料要求很高.国内由于缺乏系列数据资料,不能照搬国外的模型预测面源污染的负荷.本研究对非点源污染年负荷量估算时采用水文分析平均浓度法计算杭州市青山水库入库支流的污染物负荷；并且运用通用土壤流失方程和可浸出污染物负荷估算公式,对库区的土壤流失面源污染负荷进行了计算.结果表明:南苕溪、横溪、灵溪、双林溪面源污染严重；锦溪除了面源污染外,点源污染,即工业污染负荷占比较大.

Research on Prediction of Agricultural Non-Point Source Pollution Load of Qingshan Reservoir

The overseas development of non-point source pollution model software for data input requirements are very high.Due to the lack of a long series of data,we can’t imitate foreign model to predict non-point source pollution load.The study on non-point source pollution load estimation using the hydrological analysis method to calculate the average concentration of the pollutant load of Qingshan Reservoir tributaries.And application of the universal soil loss equation and leaching pollutants load estimation formula of reservoir area,the soil of non-point source pollution load was calculated.The results showed that: the non-point source pollution of the Nantiao stream,Heng stream,Ling stream,Shuanglin stream were serious.In addition to non-point source pollution,point source pollution of Jin stream,industrial pollution load occupied large proportion.
