Abstract: A monthly water balance model is developed based on Dalihe river basin in the Loess Plateau. According to the hypothetical climate scenarios, responses of the annual runoff to climate change are analyzed consequently. Furthermore, variation of runoff under the CO 2 content in atmosphere doubling scenario is calculated through coupling with the output results of three GCMs (LLNL, MPI, and UKMOH). The results show that the model has good simulation result to discharge of Dalihe river basin. As results indicate, annual runoff is more sensitive to precipitation change than that to temperature change. And water resources in the basin would present decreasing tendency in the next decades.
