Abstract:: In order to simulate the condition of soil erosion, and analyze the effect of land use on soil erosion, the SWAT (Soil and Water Assessment Tool) model has been built for the Fuhe watershed of Jiangxi Province. SWAT model was adopted to simulate the hydrologic and soil erosion processes of the Fuhe watershed. On this basis, the characteristics of the soil erosion modulus in the Fuhe watershed were analyzed, and the effect of land use type on the sediment yield was discussed. The results showed that the determination coefficient (R²) of the monthly flow and sediment loading for 4 observation station are between 0.7 and 0.93 in the calibration and validation period, and Nash-Sutteliffe efficiency (NSE) were between 0.64 and 0.92. The simulation precision was pretty well, and the results of the runoff and sediment simulation has higher reliability. SWAT model could be successfully used for simulation in this area. Slightly-erosion and light-erosion were the main soil erosion types. The soil erosion modulus of non-agricultural land was maximal, and the sediment yield of woodland was maximal. The research results can provide reference for soil and water conservation of study area.
