The staging simulation model is based on the flood season staging, which considering the weather system genesis and rainstorm characteristics. Moreover, the physical mechanism of rainfall runoff can be comprehensively considered, and the physical meaning of the parameter can be better reflected in different stages. In this paper, the Tingxia basins in the humid and semi-humid areas are selected, which the flood season can be divided into in plum rains period and the typhoon period, then the staged simulation model is constructed by the staged rate. Some statistical indicators are introduced to evaluate the effectiveness of the staging rainfall-runoff model in improving simulation accuracy, the simulation results are ideal, and the accuracy is improved.
