Abstract: Based on the climate data of 145 meteorological stations in Sichuan Province from 1981 to 2010, the climate suitability conditions of planting kiwifruit in those region were analyzed. Annual mean temperature, extreme maximum and minimum temperature, precipitation, frost-free period, Relative humidity, sunshine hours were selected to be the climatic regionalization indices. the climate conditions were analyzed and the division indices of climate suitability were obtained by using experience orthogonal function method and fuzzy clustering method, then the climate suitability division of the kiwifruit was built using GIS technology. at last, risk zoning for meteorological disasters by the three kinds of meteorological disaster that kiwifruit during the growth period of winter freezing injury, bud enlargement injury and sunburn injury. Provide scientific basis for the rational layout and quality evaluation of kiwifruit industry in Sichuan Province. The results showed that, the most suitable region is about 3.39×104km2, suitable region is about 8.73×104km2, less suitable region is about 8.46×104km2. The preliminary analysis of the whole Sichuan Basin region belongs to the high suitable region, but after adding three kinds of meteorological disaster risk region, the high suitable region shrinks further to the Longmen mountain vein along with the Chengdu Plain region.
