摘　　要：根据楚雄州1971～2000年的降雨量、气温、相对湿度、日照等气候因子以及海拔、土壤养分等要素,利用SPSS统计程序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气候类型进行区划,将楚雄州烤烟种植区气候类型区划为低海拔富热、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。区划结果对指导烤烟生产和发挥不同植烟区烟叶品质特色有一定的现实意义。According to altitude, soil nutrient substances and climatic factors such as rainfall, air temperature, relative humidity, sunshine from 1971 to 2000, flue-cured tobacco cultivation area in Chuxiong were classified into four types by using ＂principal components analysis＂ and ＂hierarchical cluster analysis＂ of ＂SPSS＂ software. The four types in Chuxiong were low altitude-heat-humidity area, middle altitude-warm area, high altitude-warm/cool area and middle/low altitude-heat area. The division of climate and ecology type would play an important role in directing the tobacco cultivation and flue-cured tobacco production in Chuxiong.
