为了解河南烟区烤烟焦油释放量的区域特征及其感官质量特征，选取河南烟区初烤烟叶作为试验材料，测定烟叶样品的焦油量并进行感官质量评价，采用常规统计、地统计学等进行数据分析。结果表明：（1）河南烤烟烟叶焦油量的主要分布区间为16.0～22.0 mg/支，分布频率累计值为89.19%；豫西地区焦油量最低，豫南烟区最高，其他地区焦油量居中；不同地区间焦油量存在显著差异，总体空间变化趋势由河南西部向中南部逐渐升高。（2）焦油量较高的烤烟烟叶，其感官指标中的香气质、香气量的得分均较高；焦油量较低的烟叶，其感官指标中的余味分值相对较高。河南烟区可分为豫中南高焦油区和豫西低焦油区。%In order to better understand the spatial distribution of tar release of flue-cured tobacco in Henan and its smoke quality characteristics, flue-cured tobacco leaf samples were collected from tobacco producing areas in Henan province, and tar release was determined and smoking quality was quantitatively assessed. The results showed that tar of Henan flue-cured tobacco ranged from 16.0 to 22.0 mg/cig, and the cumulative frequency distribution was 89.19%. Tar release of flue-cured tobacco in south of Henan Province was generally higher than that in west Henan and central Henan. Tar release of flue-cured tobacco in west Henan was the lowest. Tar release had a significant difference between different areas. Kriging map indicated that tar release increased from west to middle south. The higher tar release of flue-cured tobacco has a higher score of aroma quality and aroma volume, while the lower tar content of flue-cured tobacco, its after-taste has a relatively high score. Henan tobacco-growing areas can be divided into the high tar release and low tar release area.
