| Abstract: | The non-point source pollution model is an effective tool for analyzing pollution control strategies. This paper combines the AGNPS (agricultural non-point source) model with GIS to simulate cropland erosion control measures in a small watershed of the Laoyu River in Yunnan province. The watershed information database and observed field data were used to calibrate the AGNPS model and assess the effectiveness of some common cropland erosion control strategies. The results show that the AGNPS model can be applied in the watershed. The simulation results correspond well with accepted experience and the watershed field conditions, and provide valuable information for forming erosion control strategies for the watershed. |
