According to the relationship among logan growth, the degree of injury and the intensity of freezing damage, the grading indices were analyzed and decided of freezing damage for logan planting. Using the climatic data for 30 years and geographic information of 90 weather stations in Guangxi, spatial analyzing models of the indices of freezing damage were built. According to the grading indices, by the function of spatial analyses of GIS, characteristics of the spatial distribution of logan freezing damage in Guangxi were analyzed,which gave out the divisional result of freezing damage: zero, light, moderate and serious degree. It provides scientific basis for optimizing distribution of Logan planting in Guangxi, and for making use of advantage and avoiding disadvantage.
