Method for determining agricultural non-point source pollution load in hilly area

The invention discloses a method for determining agricultural non-point source pollution load in a hilly area. The method comprises the following steps: S1, dividing and classifying sub-basins of a research area; s2, selecting monitoring type sub-basins and arranging water quality monitoring points; s3, pollution load calculation of the monitoring type sub-basins; s4, calculating a typical pollution type output load standard coefficient; s5, sub-basin pollution load calculation; and S6, calculating the pollution load of the whole watershed. According to the method provided by the invention, the composition characteristics of different sub-basins are considered while accurate quantitative calculation of various types of pollution is realized, the defect of unclassified general analysis in the prior art is avoided, and the result generated by the method is high in authenticity and good in operability. 一种确定丘陵地区农业面源污染负荷的方法，包括步骤：S1：研究区子流域划分及分类；S2：监测类子流域选取及水质监测点布置；S3：监测类子流域污染负荷计算；S4：典型污染类输出负荷标准系数计算；S5：子流域污染负荷计算；S6：
