摘要
利用鸭河口水库汇流区有关土壤侵蚀基础研究资料 ,考虑预测年汇水区内植被覆盖因子和侵蚀控制因子的变化 ,运用通用土壤流失方程和可浸出污染物负荷估算公式 ,分别对土壤流失面源污染负荷和农田施肥氮磷污染负荷进行了计算 ,对鸭河口水库水资源保护及富营养化防治具有重要意义。
Based on the soil erosion data of the catchment region of the Yahekou Reservoir and the consideration of the variation of vegetation cover factor and soil erosion control factor of the region in the predicted year, the load of non-point pollution induced by soil erosion and the pollution load caused by the application of nitrogen and phosphorous fertilizers to farmlands were calculated by use of the universal soil erosion equation and the formula for calculation of the pollution load caused by leachable pollutants.
