摘　　要：本研究旨在运用主成分分析法对山东地区上部烟叶的质量进行综合评价,以便为该地区烤烟质量的准确评估提供科学依据。研究以山东10个主要植烟县2020年和2021年间105份B2F等级烟叶样品为材料,通过应用标准化法和主成分分析法对这些烟叶样品的物理特性和化学成分指标进行归类处理,并对各植烟县样品的上部烟叶质量进行分类。研究发现,单叶重与叶长和叶宽、叶片密度与叶片厚度、总糖与还原糖、烟碱与氮间极显著正相关,且主成分特征向量一致,可分别归为一类指标。根据物理特性评价结果,可将山东产区上部烟分为三类,根据化学成分评价结果,可将山东产区上部烟分为两类。综合考虑物理特性和化学成分评价结果,山东产区上部烟叶可分为四类。其中沂源、五莲、临朐为一类,兰陵、沂水、莒县、莱芜为一类,淄川、黄岛为一类,诸城则单独构成一类。The method of principal component analysis was used to comprehensively evaluate the quality of flue-cured tobacco.It provided scientific basis for accurately evaluating the quality characteristics of upper flue-cured tobacco leaves in Shandong Province.A total of 105 B2F grade tobacco samples from 10 main tobacco planting counties in Shandong Province in 2020 and 2021 were selected as materials.Standardization and principal component analysis methods were applied to classify physical and chemical composition indicators,and the quality of upper flue-cured tobacco leaves in tobacco planting counties.There were significant positive correlations between single leaf weight and leaf length and width,leaf density and leaf thickness,total sugar and reducing sugar,nicotine and nitrogen,and the principal component eigenvectors were consistent,which could be classified as one type of indicator.According to the evaluation results of physical properties,the upper flue-cured tobacco leaves in Shandong production area could be divided into three categories.Based on the evaluation results of chemical composition,the upper flue-cured tobacco leaves in Shandong production area could be divided into two categories.Based on the comprehensive evaluation results of physical properties and chemical composition,the upper tobacco in Shandong production area could be divided into four categories.Yiyuan,Wulian,Linqu were in a class,Lanling,Yishui,Juxian,Laiwu were in a class,Zichuan and Huangdao were in a class,Zhucheng alone was a class.
