Abstract:

The planting area of kiwifruit is increasing with the adjusting of agriculture industry structure in Guanzhong, Shaanxi Province. In order to provide advices of using agriculture climate resources scientifically and reasonably, optimizing industry structure and finding the best way to reduce the loss caused by natural disaster to administrator. Based on the characteristic of kiwifruit growth and 30 years climate data of Guanzhong region of Shaanxi Province, the climate suitability conditions of planting kiwifruit trees in this region were analyzed. Annual mean temperature, frost-free period and annual precipitation were selected to be the climatic regionalization indices. The spatiality of each regionalization index was built by the method of spatial analyst and mapping tools in GIS. Fuzzy comprehensive evaluation method were used to classify the suitability planting area for kiwifruit planting in Guanzhong areas of Shaanxi Province as the climate optimum suitable, less suitable and unsuitable area. Ecological climate conditions in each area were also discussed. The results indicated that the suitability planting region for kiwifruit located from the foot of the north slope of Qinling to the north bank of Weihe River, related to twenty nine counties which elevation was below 1200 m, and Hancheng County which elevation was below 700 m.
