为建立不同产区及风格烤烟烟叶与化学指标之间的关系,对2005~2009年湖南省、河南省、福建省和云南省等4省份共计1040份烟叶样品的21种化学成分进行检测,并利用Mining Tree模型进行分类-回归决策树（C＆RT analysis）数据分析。结果表明：（1）从21个烟叶化学成分中,共筛选出14个特征化学指标,其中钾和硝酸根为4省烟叶共有特征化学指标;（2）湖南、河南、福建和云南4省份识别概率最高的特征化学指标分段组合（Segment）分别为：还原糖（≤24.93%）、钾（〉1.98%）、p H值（≤5.37）（p=0.658）;钾（≤1.98%）、灰分（〉11.03%）、水溶性灰份碱度（≤0.49）、硝酸根（≤0.06%）（p=0.776）;还原糖...

An identification model of chemical components in flue-cured tobacco was established through classification and regression decision tree method (C&RT analysis) based on a database composed of 1040 samples (21 chemical components were tested) of flue-cured tobacco collected during 2005 to 2009 in Hunan, Henan, Fujian, and Yunnan provinces Results showed that: (1) a total of 14 specific-chemical components were selected from 21 chemical components, among which K2O and NO3- components were selected in each province; (2) Specific-chemical component...
