摘　　要：采用聚类分析及多重比较,分析并评价了云南7个州(市)34个植烟县的1 120份样品的主要化学成分。结果表明云南烟区烤烟化学成分均值均在优质烟的适宜值范围内,化学成分协调,是烤烟的优质产区;聚类分析方法将云南烟区分为5类,中糖中碱中钾低氯区、高糖中碱中钾中氯区、中糖低碱高钾高氯区、中糖中碱低钾中氯区和中糖中碱中钾中氯区;多重比较结果表明各类别间主要化学成分存在差异。By cluster and multiple comparisons, a comparative study was conducted for chemical components of 1120 flue-cured tobacco samples from 34 counties tobacco growth regions in seven cities, Yunnan Province. The results showed that the average chemical components of flue-cured tobacco samples in Yunnan were in normal range of high quality flue-cured tobacco, which indicated that the flue-cured tobacco had appropriate content of chemical components, and had high quality. By systematical clustering method, the tobacco regions of Yunnan were divided into five sub-regions of middle sugar-middle alkaloid-middle potassium-lower chlorine areas, high sugarmiddle alkaloid-middle potassium-middle chlorine areas, middle sugar-lower alkaloid- high potassium-high chlorine areas, middle sugarmiddle alkaloid- lower potassium-middle chlorine areas, middle sugar-middle alkaloid-middle potassium-middle chlorine areas. The multivariate analysis results showed that the difference among the locations were more significant.
