In the background of the global warming,we analyzed the historical meteorological characteristics and predicted future climate change in Jiangxi Province based on the data from 15 meteorological stations and the global climate model(GCM)data provided by the fourth assessment report of Intergovernmental Panel on Climate Change(IPCC).Some climatology statistical methods such as linear regression were used in this paper.The results showed that from 1961 to 2012,that upward trend in rainfall was not obvious in Jiangxi Province including the south part,the middle part and the north part,and the rainfall increased gradually from south to north,it was also found out that,from 1961 to 2012,the annual average temperature,highest temperature,lowest temperature warming rate were 0.16,0.12 and 0.22℃/10 a,the regional warming rate increased progressively from south to north.As predicted,in the future from 2020 to 2079,under the condition of A_2,B_1 emissions scenario,the decrement rates of annual average rainfall in Jiangxi Province will be 18.87%and 10.13%,respectively,compared to the historical reference period.From 2020 to 2079,under the condition of A_2,B_1 emissions scenario,the annual average temperature warming rate for many years in Jiangxi Province will be 0.41 and 0.22℃/10 a,respectively.
