为探明全国初烤烟叶的常规化学成分年度间变化和现状，对2007—2013年我国12个烟草主产区的初烤烟叶常规化学成分含量和协调性指标进行了初步分析。结果表明，2007—2013的7年时间内，全国初烤烟叶氯含量和钾氯比两项指标的离散程度较大，初烤烟叶的糖碱比、总钾含量、烟碱含量变异系数中等，总糖、还原糖、总氮、两糖比4项指标的变异系数最小；全国初烤烟叶常规化学成分含量适宜、协调性较好，钾离子呈现上升趋势；初步认为全国初烤烟叶还原糖含量、氯离子含量、两糖比年度间变化明显。在全国范围内，初烤烟叶还原糖含量呈下降趋势，氯离子含量呈升高趋势，两糖比呈下降趋势。

In order to explore the main chemical compositions change of flue-cured tobacco among years in China, from 2007 to 2013 we collected 40 139 samples from 12 Provinces, and determined their main chemical component contents. The results showed that the variation coefficients of chlorine content and K/Cl of flue-cured tobacco were greatest among all of the indicators, followed by variation coefficient of K content, ratio of reduce sugar to nicotine and nicotine content. Variation coefficient of total sugar, reduce sugar, total nitrogen and ratio of reduce sugar to total sugar. The main chemical components contents were suitable and harmonious. It was considered that change in reduce sugar content, chlorine content and ratio of reduce sugar to total sugar were obvious, and reduce sugar content and ratio of reduce sugar to total sugar decreased gradually, chlorine content increased gradually.
