对我国水土流失非点源污染负荷进行了全面系统的评价2000年（不含台湾、香港、澳门），通过引入降雨影响系数修正输出系数模型后，COD为1366.46万t，TP 19.77万t，TN 274.16万t，按重置成本法计算，其经济损失约为304.4372亿元，经济损失计算结果反映了该地区的非污染状况，经济损失的计算结果与实际情况基本吻合。在一定程度上对我国水土保持的点源污染进行了分析，为流域水土保持工作和水污染防治提供初步量化的决策依据。
It conducts an overall and systematic evaluation of non-point source pollution load caused by soil erosion in China(excluding Taiwan,Hongkong and Macao) of year 2000 after revising output coefficient model by introducing rainfall affecting coefficients,i.e.COD 13.664 6 million tons,TP 197 700 tons and TN 2.741 6 million tons.Its economic loss is about 30.443 72 billion Yuan calculated by the method of cost of replacement.The outcomes of economic loss calculation reflect the status of non-point source pollution of China soil and water conservation to a certain degree and provide decision basis of preliminary quantification for soil and water conservation work and water pollution prevention and control of river basin.
