摘　　要：基于GIS技术和气候学模型,融合经度、纬度、海拔高度等地理信息,对平均气温资料进行较高空间分辨率1km×1km的地理订正,结合广西水稻生长发育状况和受害指标,对广西水稻冷害发生发展及其强度、范围的进行实时动态监测、预警,结果表明,2009年5月中下旬冷害过程的监测效果与冷害实际情况比较相符。Based on GIS techniques and a climatology model,using several types of geographic data such as longitude,latitude,altitude,etc.,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.
