英文摘要	In view of the loess plateau features of basin, modified the Distributed Time-Variant Gain Hydrological Model (DTVGM), and expanded the model to month, daily and real time scales. The DTVGM, coupling the advantages of both nonlinear and distributed hydrological models, can simulate variant hydrological processes under different environment conditions. Then, three models are applied to three catchments, which are Dali River, Xiaoli River, and Chabagou catchments. The three catchments area is different; there are different spatial scales. The result of simulation is very good. Last, the model can be used to analyze the temporal and spatial change of hydro-cycle and human activity effect. Satisfactory results were obtained in forecasting the time-space variations of hydrological processes and the relationships between land use/cover change and surface runoff variation.
