Abstract: As a consequence of global warming,chilling injury in summer is becoming one of the main weather disasters of rice crop in Hubei Province.Based on the data of the meteorology and the yield of the rice from 1981 to 2006,the spatial distribution characteristics of the rice sensitivity of chilling injury in summer were analyzed by using ArcGIS technique and SAS system.The result showed that the rice sensitivity of the cold summer in Hubei was complex and variable.The sensitivity in the areas such as the north-western and the eastern parts of Hubei,where the intensity of disaster was enhancing obviously and the frequency was increasing significantly in recent years,was stronger than the areas such as the south-western and Jianghan Plain where the changing of the intensity and the frequency of the disaster were small.Therefore,rice production in the north-western and the eastern parts of Hubei was apt to be affected adversely by the disaster of the equalty intensity.
