The geographic distribution patterns of three endangered Vitis species(V.yunnanensis C.L.Li,V.hui Cheng and V.wenchouensis C.Ling ex W.T.Wang)in China were investigated through analyses of their comprehensive geographic distribution information.The current distribution patterns of the three Vitis species were mapped by ArcGIS software.Their potential future distribution patterns under the impacts of present climate and potential future climate change were simulated and predicted using BIOCLIM model.The results showed that the three wild Vitis species are distributed mainly in south of the Yangtze River.V.hui is mainly distributed in northern Jiangxi Province,and V.wenchouensis in southeastern Zhejiang Province,while V.yunnanensis is distributed in a scattered pattern.The dominant factors affecting the geographic distribution of V.yunnanensis are mean temperature of the driest quarter,mean annual temperature range,and annual precipitation.Annual mean temperature,precipitation seasonality,mean temperature of the wettest quarter and mean monthly temperature range are that for V.hui;and minimum temperature of the coldest month,annual precipitation,and precipitation of the driest month are that for V.wenchouensis.Simulated present distributions of these three Vitis species by BIOCLIM model match very well their actual distribution ranges,indicating that the simulation by BIOCLIM model is accurate.The current and potential future distributions of these species are and will still remain in south China.Under the future climate scenario with a doubled CO_2concentration,these three Vitis species may all shift northward;but the ranges of the suitable zone change are not obvious.
