Summary: | The invention relates to an in-basin water and soil loss non-point source pollutant river-entering amount accounting method, which can effectively solve the problems of water and soil loss non-point source pollutant river-entering amount accounting and water environment non-point source pollution treatment. The method comprises the steps: according to public data measured by a hydrological controlstation in a river sediment report, calculating the sediment loss amount in a drainage basin; obtaining soil type information which is prone to water and soil loss in the drainage basin from a Chinasoil type database, and calculating the average content of total nitrogen and total phosphorus on the surface layer of the soil prone to water and soil loss; and adopting a water and soil loss non-point source pollutant loss amount accounting formula to calculate the water and soil loss non-point source pollutant loss amount and the river entry amount in the drainage basin. The method is simple and practical, required basi |
