After dividing the source regions of the Yellow River into 38 sub-basins, the paper made use of the distributed hydrologic model--SWAT model to simulate discharge with validation of the measured yearly and monthly runoff data from the Tangnag Hydrologic Station, and simulation results are satisfactory. Five land-cover scenario models and 24 sets of temperature and precipitation combinations were established to simulate annual runoff and runoff depth under different scenarios. The simulation shows that with the increase of vegetation coverage annual runoff increases and evapotranspiration decreases in the basin. When temperature decreases by 2oC and precipitation increases by 2%, basin runoff increases by 39.69%, which is the largest among all scenarios.
