摘　　要：Based on GIS techniques,a climatology model,and several types of geographic data such as longitude,latitude,altitude,cold damage data in Guangxi were corrected according to specific geographic details of 1 km×1 km.Considering growing conditions and cold-index of rice in Guangxi,the real-time monitoring and pre-warning on the occurrence,development and intensity and scope of rice in Guangxi were realized.The monitoring effects of damage process in middle and late May of 2009 was comparatively accordant with the actual situations.Based on GIS techniques,a climatology model,and several types of geographic data such as longitude,latitude,altitude,cold damage data in Guangxi were corrected according to specific geographic details of 1 km×1 km.Considering growing conditions and cold-index of rice in Guangxi,the real-time monitoring and pre-warning on the occurrence,development and intensity and scope of rice in Guangxi were realized.The monitoring effects of damage process in middle and late May of 2009 was comparatively accordant with the actual situations.
