摘　　要：为有效进行烤烟烟叶产地识别和分类使用,对烤烟烟叶外观特征进行区域归类。选取福建南平、四川凉山、湖南郴州、河南许昌、贵州遵义、云南曲靖等43个产地的烤烟C2F等级烟叶,分析了烟叶的底色、厚度、蜡质感、柔韧性、叶面叶背颜色差、叶尖叶基身份差、光泽、叶面组织等15项外观特征指标,并采用主成分分析法提取了7个主成分,基于综合得分对43个产地烟叶进行聚类。结果表明:(1)提取的7个主成分累计贡献率达到83.476%,确定叶面组织、柔韧性、色度、油分、厚度、底色、叶尖叶基身份差、成熟度、颜色、叶面叶背颜色差10项指标为烤烟烟叶外观特征的评价指标。(2)若以平方欧氏距离10作为分类标准,可以将所有烟叶样品分为8类,第一类为云南、贵州、四川、湖北(恩施和宜昌);第二类为河南(驻马店和南阳)、陕西(安康);第三类为福建、湖南(湘西);第四类为重庆(黔江);第五类为河南(许昌和平顶山);第六类为湖南(郴州和永州)、江西;第七类为黑龙江、辽宁、吉林、陕西(商洛)、山东;第八类为河南(漯河)、安徽(宣城)。To effectively recognize the growing area and classified usage of flue-cured tobacco leaves,the appearance of flue-cured tobacco leaves were classified according to growing areas.Flue-cured tobacco leaves（C2 F） were sampled from 43 growing areas（Nanping in Fujian,Liangshan in Sichuan,Chenzhou in Hunan,Xuchang in Henan,Zunyi in Guizhou,Qujing in Yunnan,etc.）.Fifteen appearance characters（background color,thickness,waxiness,flexibility,leaf color difference between front and back,leaf body difference between tip and base,luster,leaf surface tissue,etc.） of the samples were analyzed.Seven principal components were extracted via principal component analysis,and the samples from the 43 areas were clustered based on the comprehensive scores.The results showed that：1） The accumulated contribution rate of the seven principal components reached 83.476%.Ten indexes（leaf surface tissue,flexibility,color intensity,oil,thickness,background color,leaf body difference between tip and base,maturity,color and leaf color difference between front and back） were determined as the evaluation indexes of appearance characteristics of flue-cured tobacco leaves.2）Taking the square Euclidean distance of 10 as a standard,all of the samples could be classified into 8 categories：Category Ⅰ（samples from Yunnan,Guizhou,Sichuan,Enshi and Yichang in Hubei）,Category Ⅱ（samples from Zhumadian and Nanyang in Henan,Ankang in Shaanxi）,Category Ⅲ（samples from Fujian,Xiangxi in Hunan）,Category Ⅳ（samples from Qianjiang in Chongqing）,Category Ⅴ（samples from Xuchang and Pingdingshan in Henan）,Category Ⅵ（samples from Chenzhou and Yongzhou in Hunan,Jiangxi）,CategoryⅦ（samples from Heilongjiang,Liaoning,Jilin,Shangluo in Shaanxi,Shandong）,Category Ⅷ（samples from Luohe in Henan,Xuancheng in Anhui）.
