| Abstract: | Present study explored the effects of wetland area change in Sanjiangyuan area on the climate by using RegCM3 model. The meteorological effect was simulated by adjusting the parameterized scheme of underlying surface covering with the meteorological model, mainly the wetland area change, and the interactional effect between the change of marsh area and climate was agrued.The rule of temperature and rainfall variation among 18 different meteorological sites were analysed by simulating the climate change for 15 years using RegCM3 model through the actual underlying surface in 1980 and 2000. The results showed that when wetland area descended, the regional temperature increased, the rainfall decreased, this trend was more obvious in western area. |
