摘　　要：低温寒害是影响香蕉生产的主要气象因子,为了更好地了解香蕉低温寒害的特征及规律,并为广西香蕉生产的优化布局提供科学依据。根据香蕉生长状况、受害程度与低温寒害强度关系,分析确定香蕉寒害等级指标;利用广西90个气象台站30a的气候资料和台站地理信息数据等材料,采用GIS技术和数理统计回归分析以及气候资源的小网格推算方法,建立寒害指标的空间分析模型,推算出1km×1km分辨率的寒害指标空间分布;并根据香蕉寒害分级指标,通过GIS的空间分析能力,分析广西香蕉低温寒害的空间分布情况,得出广西无寒害和轻度、中度、严重寒害等4个区域的分区结果,并对分区结果进行分析和建议。Cold damage is the primary climate factor effecting the production of banana in Guangxi. In order to enhance understanding of characteristic of cold damage banana, and to provide scientific basis for optimizing distribution of banana planting in Guangxi, the grading indices were analyzed and decided by cold damage for banana planting, according to the relationship among banana growth, the degree of injury and the intensity of cold damage. And using the climatic data of 30 years and geographic information of 90 weather stations in Guangxi, spatial analyzing model of the indices of cold damage was built by the regress method of mathematical statistic. The indices of cold damage in Guangxi are reckoned on the little grids of 1 km×1 km by GIS technology and small grid calculating method of the climate resources. According to the grading indices, by the function of spatial analyses of GIS, the spatial distribution of banana cold damage in Guangxi were analyzed, which gave out the divisional result of cold damage： zero, light, moderate and serious degree, and the analysis and corresponding suggestions for the results of the different cold damage region were put forward.
