| Abstract: | 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 from 0.761 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 clusters:Ⅰ.Fuyuan,Shizong and Luoping,Ⅱ.Luliang,Qilin,Xuanwei,Malong and Zhanyi,Ⅲ.Huize. |
