摘　　要：为综合评价湘西州烤烟化学成分可用性,采集了湘西州7个产烟县的C3F等级烤烟样本48个,测定了烤烟化学成分,应用模糊数学对其可用性进行了评价。结果表明:湘西州烤烟具有糖含量较高,氯含量偏低,烟碱、总氮、钾含量和糖碱比、氮碱比、钾氯比适宜的特点;不同产烟县间以泸溪县烤烟的化学成分可用性最高,花垣县烤烟的化学成分可用性相对较低。不同产烟乡镇以浦市镇、湾塘乡、水田河乡烤烟化学成分可用性较高,山江镇、千工坪乡、排碧镇、红石林镇、碗米坡乡、雅酉镇、董马库乡烤烟化学成分可用性相对较低。湘西州烤烟CCUI值空间分布有从东南向西方向递减的分布趋势。The chemical components of flue-cured tobacco leaf were by detecting 48 samples with C3 F grades from the tobacco-growing counties in Xiangxi Autonomous Prefecture in order to evaluate the usability by using fuzzy mathematics. The results showed that： the sugar content of flue-cured tobacco leaf was high, chlorine content was lower, and nicotine, total nitrogen, potassium, sugar/nicotine, nitrogen/nicotine, potassium/chlorine were at fight levels. The usability index of chemical components in Luxi County was the best among different counties, and that in Huayuan County was the lowest. The usability indexes of chemical components in Pushi, Wangtang, Shuitianhe were superior to another towns and those in Shangjiang, Qiangongping, Paibi, Hongshilin, Wanmipo, Yayou, Dongmaku were inferior. The chemical components usability index of flue-cured tobacco decreased gradually from southeast to west in spatial distribution.
