摘要
利用SPSS(Statistical Program for Social Sciences)软件的主成分分析和动态逐步聚类方法对楚雄州烤烟种植区进行了生态类型的区划试验,结果在GIS平台上输出。区划结果表明,楚雄州可划分为低海拔富热富湿植烟区、中海拔温暖植烟区、高海拔温凉植烟区和中低海拔富热区4个烤烟可种植区和1个燥热非植烟区。
With the principal component analysis and dynamic stepwise cluster analysis functions of statistical software SPSS（Statistical Program for Social Sciences）,the tobacco growing areas in Chuxiong were ecologically regionalized experimented and demonstrated on a GIS platform.The results showed that Chuxiong could be divided into 4 types of tobacco growing area（low altitude hot humid area,middle altitude warm area,high altitude warm/cool area and middle to low altitude hot area） and 1 dry and hot non-tobacco growing area.
