Using the NCAR Community Atmosphere Model(CAM4.0),two sensitivity experiments integrated 25 years are performed under the conditions of potential vegetation and current vegetation,respectively.The possible influences of the land-use change(LUC) on the land surface energy balance,hydrological cycle and climate over East Asia are investigated.Results show that the current LUC featured by rapid forest degradation and cropland increasing significantly alters the land surface characteristics,leading to increase of surface albedo in all seasons over East Asia,which in turn changes the surface energy balance and hydrological cycle over the region in winter and spring.In addition,impacts of large-scale LUC on the general circulation over East Asia are also detected.Current LUC tends to cause evidently stronger winter monsoon circulation and slightly enhanced summer monsoon.No evident changes of air temperature induced by current LUC are found,but more(less) spring precipitation happens in the north(south) of East Asia under the impacts of LUC.
