Regional simulation of wheat yield in China under the climatic change conditions
气候变化下我国小麦产量变化区域模拟研究

In this research,we applied the(newest) emission scenarios of the sulfur and greenhouse gases,i.e.(Intergovernmental) Panel on Climate Change(IPCC) Special Report on Emission Scenarios((SRES)) A2 and B2 scenarios,combined with the RCM ((Regional) Climate Model) model and(CERES)-Wheat model to (investigate) the change of wheat(yield) in 2080s.The results show(that) under the two emission scenarios,in 2080s,the yield of rainfed wheat decreases(dramatically;) irrigation can offset the decrease,but can not stop it;the yield increases for both irrigated wheat and rainfed wheat if the direct effect of CO_2 is considered in the simulation.
