In order to adapt to climate change,give full play to favorable agro-climatic conditions for Apple planting in Xinjiang and avoid adverse weather disasters,It would provide scientific basis to scientifically formulate the development plan of apples in Xinjiang. Based on the data of daily mean temperature and minimum temperature from 102 meteorological stations in Xinjiang from 1961 to 2015,the fundamental spatial-temporal change characteristic of key climatic factors(annual mean temperature,days of lowest temperature below-20℃,mean temperature from Jun. to Aug. and mean temperature in Jan.) affecting apple-planting were analyzed by using the methods of linear regression,accumulative anomaly,T-test and mixed spatial interpolation technology based on ArcGIS. And the impact of climate change on apple-planting climatic suitability and distributed areas were studied by combining with the change characteristics of key climate factor before and after mutation. The main results showed,spatial distribution of above climatic factors had very obvious difference from place to place in Xinjiang,the mean temperature of annual,from Jun. to Aug.,and in Jan. generally,they were higher in south than in north,in plain and basin than in mountain regions. The days of lowest temperature below-20℃ were more in north than in south,in mountain regions than in plain and basin. In the background of global warming,the mean temperature of annual, Jun. to Aug.,and in Jan. presented significantly increasing trend with the rate of 0.305℃ /10a,0.210℃ /10a, 0.242℃ /10a in recent 55 years,and they had mutation in 1997 and1979 respectively. The days of lowest temperature below-20℃ presented significantly decreasing trend with the rate of-1.987d /10a and had mutation in 1985. By the climate changes,the apple-planting suitable area and unsuitable area decreased,sub-suitable area were increased after 1997 than before in Xinjiang region. Under the background of global warming,the climate in Xinjiang has significant warmed in the past 55 years,the resources of the agricultural heat in Xinjiang was good overall to plant characteristic fruit. The research conclusion showed the agricultural climate conditions were advantageous to plant apple. Therefore,according to the local climate characteristics and its change,the apple development planning and planting areas should be adjusted,and avoid the bad meteorological disasters. Finally,scientific plans should be made to promote the stable development of Xinjiang's apple production and provide a reference basis for the future research.
