The Wuyur River Basin, located in the inland semi-arid region, is sensitive to climate change. The streamflow of Wuyur River is an important recharge source of Zhalong Wetland. The study on the streamflow change associated with the future climate change scenarios has a practical significance for the local socio-economic development and eco-environmental protection of Zhalong Wetland. With the distributed hydrological model of SWAT, the streamflow in the Wuyur River Basin was simulated, and the hydrological response to climate change was analyzed. The simulated results showed that the SWAT model could effectively simulate the streamflow change in the Wuyur River Basin. Especially, at the stations with large amounts of streamflow, the efficiency of simulation was satisfactory. The influence of climate change on streamflow was significant. The streamflow in the future climate change scenarios decreased gradually over time, and different hydrological stations had different streamflow change amplitude. Considering the decrease in streamflow, we need to apply a reasonable water resources allocation for the wetlands in the watershed to alleviate the adverse effects.

Key words: climate change, streamflow simulation, SWAT model, Wuyur River Basin
