摘　　要：为区分会理烟区不同微生态区烤烟的质量特征差异,选取30个自然植烟村的C3F等级烟叶,运用隶属函数对烤烟的28项化学成分、协调性、感官评吸及外观质量指标的原始数据进行标准化处理,并采用主成分分析和聚类分析法建立烤烟综合质量评价模型,最后通过反距离权重插值法对烤烟质量区域分布差异进行可视化。结果表明,所提取的6个主成分累计贡献率达82.259%,基本上反映了28项指标的全部信息;在平方欧式距离4.0处可将所有样品分为4类,4类烤烟综合评价得分依次为2.070、1.731、1.459和0.950;烤烟综合质量指数区域差异明显,空间分布整体上呈现由西北往东南递减的分布趋势。研究明确了会理县域内烟叶质量的区域分布特征,可为会理烟区烤烟的总体生产布局规划以及工业企业合理利用产区不同质量特征的烟叶原料提供理论参考。In order to distinguish the quality characteristics of flue-cured tobacco in different micro-ecological zones of Huili tobacco area,C3F grade tobacco leaves from 30 tobacco planting villages were selected.Membership function was used to standardize the raw data of 28 chemical components,coordination,sensory evaluation and appearance quality indicators of flue-cured tobacco,and principal component analysis and cluster analysis were used to establish a comprehensive quality evaluation model for flue-cured tobacco.Finally,the regional difference of flue-cured tobacco quality was visually represented by inverse distance weight(IDW).The results showed that the contribution rate of six principal components reached 82.259%,which could basically reflect all the information of the 28 chemical components.At the square Euclidean distance of 4.0,all samples could be divided into 4 categories,and the comprehensive evaluation score of the 4categories of flue-cured tobacco was 2.070,1.731,1.459 and 0.950,respectively.The regional difference of flue-cured tobacco comprehensive quality index was obvious,and the overall spatial distribution showed a decreasing trend from northwest to southeast.The regional distribution characteristics of tobacco leaf quality in Huili were clarified.The study will provide reference for the production layout planning and the rational utilization of tobacco raw materials.
