Abstract:: Taking the Luanhe River Basin as the research area, we constructed a total of sixteen climate change scenarios on the basis of the previous studies in the context of future climate change in Haihe River Basin. With the distributed hydrological model of SWAT (Soil and Water Assessment Tool), the monthly streamflow in the study area was simulated, and the hydrological response to climate change was evaluated. The results showed that the calibrated SWAT model was able to well simulate the monthly flows and thus extensively applicable in the Luanhe River Basin. Besides, temperature rising might resulted in increased evaporation and decreased runoff. Therefore, the runoff in the Luanhe River Basin could be further deteriorating under the changing climate that is characterized by rising in temperature and the uncertainty in precipitation trends. Under the climate scenario with increased precipitation, the increase trend of average annual surface runoff had significantly spatial variability, especially in the downstream of the basin, including Qianxi County etc. The results would be greatly helpful for providing some references for water resources management under the changing environment in Luanhe River Basin.
