摘　　要：运用主成分分析法和对云南省保山市61个植烟乡镇的海拔及近30年的温度、降雨量等主要因子数据进行分析,结果表明保山烟区的主要因子有2个,分别是光照因子和热量因子,累计贡献率达89.925%;利用系统聚类方法将保山烟区划分为3个气候类型区域,并分析了各类型的气候特征。高黎贡山以东划分为Ⅰ类生态区,特征是"中海拔、适雨、日照中等、气温较高";高黎贡山以西划分为Ⅱ、Ⅲ类生态区,Ⅱ类生态区特征是"中海拔、多雨、日照中等、气温较高",Ⅲ类生态区特征是"低海拔、多雨、日照长、气温高"。研究结果为保山市烟区合理布局烤烟种植区域提供了理论依据。Based on the principal component analysis method, the author analyzed altitude and a total of 30 years of illumination, temperature, rainfall of meteorological factors data in Baoshan tobacco cultivation area, which included 61 township.The results showed that 2 main factors were found through principal component analysis,that was illumination nitrogen factor and quantity of heat factor. The contribution rate of first- second characteristic roots was 89.925%. By systematical clustering method, the tobacco regions of Baoshan were divided into 4 climate types area. TheⅠclimate type that has characterized by' middle-elevation, suitability in rainfall, rich in sunshinet,high temperatures'sizeably distribute in the east of Gaoligong Mountain. TheⅡclimate type that has characterized by 'middle in elevation, rich in rain, moderate in sunshinet, high temperatures'sizeably distribute in the east of Gaoligong Mountain. The Ⅲ climate type that has characterized by 'lower in elevation, rich in rain, rich in sunshinet, highest temperatures'majorly distribute in the west of Gaoligong Mountain.
