Abstract：The meteorological date of 19 meteorological stations in Gansu Hexi Corridor from 1951 to 2010 and the field observation and investigation data of wine grape were used for this study.The results showed that:the sunshine hours in the Hexi wine grape growth season from April to September were 1 374 ~1 866 hours;the effective accumulated temperature of ≥10℃ was 1 370 ~1 850℃;the diurnal range of tem-perature at the sugar content accumulating stage was 10 ~18℃.The rich energy resources and great diurna range of temperature were the climatic advantages for planting wine grape,which were beneficial to the yield formation,coloration,increase of pigment and accumulation of sugar.Using GIS,the eco -climatic planting regions of wine grape in Hexi Corridor were divided according to the climate change in the recent 30 years, and the best geographical distribution of wine grape was obtained.This had guiding significance for the exploi-tation and utilization of climatic resources and the adjustment of agricultural production structure.
