摘要：The study on prediction model of watershed soil erosion need achieve comprehensive management to a small watershed and make macro decision-making such as land use plans, at the same time it's the premise to evaluate the effect of small watershed water and soil conservation. Through the analysis of the dynamic process of erosion and the reasonable coupling to space-time relationship between surface - channel and channels, a soil erosion dynamic simulation model of watershed system is established on the basis of continuous flow equation, conservation of momentum equation and mass conservation equation of sediment. The model will provide a theoretical basis to soil erosion dynamic simulation and prediction not only for a small watershed but also for large-scale basin.
