以曲靖各县区1971-2007年累计37年的气象观测数据为基础资料,采用主成分聚类分析法对各县区烤烟气候进行了初步分类,并基于模糊数学原理,运用多元统计分析方法对曲靖烤烟气候适宜性进行了综合评价,结果表明:曲靖烟区烤烟气候适宜性指数(climate feasibility index,CFI)为0.839±0.040,变幅为0.761-0.875,均为最适宜或适宜烤烟气候区；主成分分析提取了曲靖烤烟气候的前2个主成分(累计贡献率达87.064％),分别由水湿因子和温热因子构成,利用主成分聚类可将曲靖烟区9个植烟县大致分为三类,富源、师宗和罗平归为一类,陆良、麒麟、宣威、马龙和沾益归为一类,会泽自成一类.%Based on the meteorological data from 1971 to 2007 at the meteorological stations in Qujing City, climatic feasibility to tobacco growing was evaluated comprehensively by using the method of fuzzy math and multivariate statistical analysis. The method of PCCA (principal component cluster analysis) was used to classify 9 counties into several classes. The results indicated that the climatic feasibility indexes (CFI) for flue-cured tobacco was 0.839 ±0.040 and ranged from0.761 to 0.875, all the counties were feasible or most feasible tobacco-growing areas. Two principal components of Qujing flue-cured tobacco climate (total contribution of 87.064% ) were extracted by principal component analysis, which were constituted by humidity factor and temperature factor. Nine counties were grouped into 3 dusters: I . Fuyuan, Shizong and Luoping, II . Luliang, Qilin, Xuanwei, Malong and Zhanyi, Ⅲ. Huize.
