Abstract: Water pollution in China is usually caused by multiple pollution sources. Understanding the contribution of each pollution source and its spatio-temporal patterns is crucial to the development of effective watershed pollution control programs. In this study, Soil and Water Assessment Tool (SWAT) was used to simulate the processes of nitrogen discharge, migration, and transformation in the Ru River Basin. The SWAT simulation results were used to estimate total nitrogen (TN) load contributions from different pollution sources in each sub-basin. Clustering analysis results showed that TN loads were mainly from sewage treatment plants and industries in the north and some areas in the middle, septic tanks and crop production in the south and some regions in the middle, and crop production in the east and west. The distinct spatial disparity in TN pollution source composition underlined the necessity of formulating region-specific watershed pollution control measures.
