Abstract: In order to know the current pollution status of rural living non-point source pollution in Sichuan Province, and provide the basis for the rural living non-point source pollution control, the author built estimate model of pollution load (household garbage, domestic sewage and human wastes) from 3 stages (generation, discharge and export) depended on the export coefficient model. Then the author estimated the total nitrogen (TN), total phosphorus (TP) and chemical oxygen demanded (COD) loads of rural living non-point source pollution in 21 cities of Sichuan Province with the established estimation model, and the total amount of loads and the proportion pollution were analyzed. At last, the author combined with the third grade of surface water standard of China (GB 3838—2002), calculated the into river contribution rates of TN, TP and COD, respectively. The results showed that the generation loads of TN, TP, and COD were 421070 t, 91122 t and 2023186 t, discharge loads were 120675 t, 26298 t and 419969 t and export loads were 44499 t, 5780 t and 142049 t, respectively. In Sichuan Province, Nanchong, Dazhou and Chengdu had the maximal generation and discharge loads, while Yibin, Nanchong and Dazhou had the maximal export load. In export progress, the contribution rates of TN, TP and COD into rivers were minor in Sichuan Province. However, the contribution rate of TN in Suining and Neijiang exceeded the third grade for 100%. The results showed that rural living non-point source pollution in some areas of Sichuan Province was very serious with the development of economy, and the control should be enhanced in the future. The method used in this study could offer reference to other areas for estimating the rural living non-point source pollutant load.
