摘要：

Runoff process in the upper reaches of the Han River was simulated by distributed hydrological model-WEP model. The model was calibrated by observed hydrological data from 1981 to 1985 at Danjiangkou reservoir, and was verified by observed hydrological data from 1986 to 1990. Monthly Nash coefficients were all above 0.8, excellent results were got. On this basis, runoff in upper Han River reaches in response to climate change was further explored. In recent forty five years, temperature in the region was presented as a fluctuant rising trend, meanwhile, precipitation and runoff were showed as a downward trend. At different climate change scenarios, runoff changed significantly in forty five years, but change ratio remain in the same level, and effect on runoff by precipitation is larger than temperature.
