In order to accurately assess the main sources of pollution and major pollutants of water environment in Shehong County, and provide a theoretical basis for the local water environment pollution control. We used the source strength coefficient method and the output coefficient method to analyze the river pollution load of pollutants of the rural non-point source pollution from the 6 kinds pollution sources and the 30 towns, which in Fujiang Basin (shehong territory). The equivalent pollution load method was adopted to account the load ratio of every town. The results show that the main pollutant in the study area is total nitrogen which is 1 443.9 tons; the main pollution source of Taihe Town is the industrial pollution, and the proportion of pollution accounted for 63.3%, the main pollution sources in other towns are rural residents living pollution, and the proportion is more than 50%; among the 30 towns, the total standard pollution load of 8 towns is greater than 100 tons. It can be seen that the non-point source pollution in the study area is serious; the main source of pollution is the pollution of rural residents. Appropriate control measures should be taken according to the distribution of non-point source pollution due to their significant different spatial distribution and the contributions of different pollutants.
