摘　　要：根据1961～1990国家气象局公开发表的88个县市的所有气象教据，在地理信息系（GIS）中，分别取各县市的经纬度值，以它们的年平均气温、1月均温、7月均温、活动积温、霜期、日照时数、日照率、年平均相对湿度、年降雨量及海拔等10个参数共计840个数据为分类依据.利用两维图论聚类分析技术，把贵州省88个县市1541个乡镇划分为4个一级区、8个二级区（亚区），并对各区的熟制、地形地貌、土壤、生态气候类型进行了分析、比较和评述，划分结果可为制定贵州省马铃薯产业发展规划提供参考依据。840 datum from ten parameters （mean annual temperature, mean temperature in January, mean temperature, active accumulation temperature, frost period, hours of sunshine, rate of sunshine, annual average relative humidity, annual rainfall and elevation） of 88 cities and counties based on their latitudes and longitudes in GIS are used as the classification bases according to their meteorological datum openly published by State Meteorological Administration from 1961 - 1990. 1541 townships of 88 cities and counties in Guizhou are divided into four regions and eight sub-regions by using the two-dimensional map clustering analysis technique for growing potato. The cropping system, surface relief and land form, soil and ecoclimate type of different regions are analyzed, compared and evaluated respectively. The division results can provide the reference basis for the plan of potato industrial development in Guizhou.
