摘要：
The dual non-point source model independently developed by China is chosen to study its practical applicability in the experimental catchment area of Hebei Yuecheng Reservoir in combination with the remote sensing and GIS data, and to study the spatial distribution pattern of the non-point source Phosphorus (P) pollution. The result shows that: (1) the simulated non-point source P load is strongly related to the observation data of the hydrologic stations such as Liujiazhuang, Guantai and etc; (2) the farmlands, urban and rural residential areas in the catchment area are the major risk sources of non-point source pollution; (3) the two assessment units, catchment unit and administration unit, are employed in this study. They are complementary to each other.
