摘要：
Research and development of watershed scale soil erosion model has been the frontiers in the field of soil erosion in the past 50 years and has been focused on by water and soil conservation workers around the world. However, the present models cannot well simulate the actual conditions of soil erosion in hilly areas. Soil erosion model for small-watershed of hilly areas (SEM-SHA) is a new distributed hydrological model which is developed according to the physical process of sediment yield in the hilly areas. This paper introduced the development, characteristics, structure and function, and input and output of the model. The model was also used in the Lizi River watershed in the hilly areas of the Jialing River. The simulation results showed the SEM-SHA model was fit for the hilly region.
