As one of the major water sources in Ningxia of China, it is of great importance to maintain healthy ecological environment of the Yellow River. In this essay, basin hydrological model is adopted to simulate the influences of prediction of climate changes on runoff in river basin, which is of great theoretical and realistic significance to flood and draught control plans as well as long-term exploitation and utilization of water resources in Ningxia Section of Yellow River Basin of China Based on analysis of the changing characteristics of major climates and hydrological features in Ningxia Section of Yellow River Basin of China, distributed hydrological model SWAT (Soil and Water Assessment Tool) coupled with GIS is used in this study to simulate the yearly and monthly runoff volumes under 15 different climate changes, with the aim to explore the influences of climate changes to runoff The results show that the runoff volume in the basin has negative correlation with the temperature but in positive correlation with the rainfall, and that the influence of the changes of rainfall in the basin on the runoff is greater than that of the temperature, which could provide basis for decision making of water resource management in Ningxia Section of the Yellow River Basin of China.
