Abstract: The spatial simulation quality of climate change directly affects simulation accuracy of climate-vegetation system at regional level. In this paper, mean annual temperature (MAT) and mean annual precipitation (MAP) of Jiangxi province are simulated by methods of HASM, IDW, Kriging and Spline. The cross-validation results show that HASM has the highest accuracy. The MAT, MAP and mean annual potential evapotranspiration ratio (MAPER) of Jiangxi in the last 60 years are respectively simulated at time resolutions of 10 years and 30 years. The climate-vegetation system of Jiangxi is simulated by running Holdridge life zone (HLZ) model on the simulated climatic surfaces of MAT, MAP and MAPER at the time resolutions of 10 years and 30 years. From 1961 to 2010, both MAT and MAP in Jiangxi went up. The changed lattices of HLZ ecosystems was about 20% in Jiangxi province. The change of HLZ ecosystems was mainly driven by the climate warming. The warm temperate moist forest had the most significant change compared with the other six HLZ ecosystems.
