应用逐步回归分析方法和GIS技术，构建福建省越冬期极端最低气温（ Td ）和4个等级冻害指标（-2℃＜Td≤0℃、-3℃＜Td≤-2℃、-4℃＜Td≤-3℃、 Td ＜-4℃）发生频次空间分析模型，根据荔枝冻害评价指标，对漳州市荔枝种植区进行区划。结果表明：1）漳州市荔枝种植区可分为微冻害区、轻度冻害区、中度冻害区、重度冻害区，其中最微冻害区、轻度冻害区、划区结果与实际荔枝种植分布较吻合；2）漳州市荔枝种植微冻害区、轻度冻害区主要分布在漳州市东南部及西北部低山丘陵，中度冻害区、重度冻害区主要分布在适宜区以西海拔较高区域。

The spatial models about winter extreme low temperature and 4 levels′( -2<Td≤0℃,-3<Td≤-2℃, -4<Td≤-3℃, Td<-4℃) cold damage model were built , by using stepwise regression analysis and GIS technology , then the planting areas of Litchi in Zhangzhou were divided according to the grading index .The result showed that: 1) the planting areas of Litchi in Zhangzhou were divided into slight freezing injury areas , mild freezing injury areas , moderate freezing injury are-as, and severe freezing injury areas .Slight and mild freezing injury areas are consistent to real plant-ing areas of Litchi; 2 ) slight and mild freezing injury areas are located in the southeast and northwest of Zhangzhou with low mountain and hills , moderate and severe freezing injury areas are located in the west parts with higher mountains .
