摘　　要：为明确湘西烟叶的香型香韵区域特征和空间分布特征,对来自湘西烟区的41个烟叶样品进行了感官评价。结果表明:1湘西烟叶风格具有尚显著至稍显著的浓香型特征;香韵种类主要为干草香、焦甜香与焦香。2主产烟县烟叶焦甜香和木香香韵差异显著,烟叶浓香型、干草香、正甜香、坚果香、焦香、辛香的县域差异不显著。3K326品种浓香型风格较云烟87明显。4高于900 m海拔的烟叶浓香型风格相对较彰显。5浓香型,干草香、焦香、坚果香、木香、正甜香在区域空间分布上表现出从北部向南部递减的趋势,焦甜香在区域空间分布上有从东部向西部递减的趋势,辛香在区域空间分布上有从西部向东部递减的趋势。In order to investigate the regional characteristics and spatial distribution of flavor style and aroma note of Xiangxi tobacco, the sensory evaluation of 41 tobacco leaf samples from Xiangxi tobacco growing areas was carried out. The results showed that： 1） The flue-cured tobacco leaves from Xiangxi featured slightly significant to sort of significant robust flavor style with the main aroma notes of hay-like, burnt-sweetness and burnt scents. 2） The burnt-sweetness and woody scents differed significantly between leaves from different counties, while the robust flavor style, hay-like, pure-sweetness, nutty, burnt and spicy scents did not. 3） The robust flavor style of cv. K326 was more obvious than that of cv. Yunyan87. 4） The tobacco from the areas at an altitude of above 900 m had more evident robust flavor style. 5） Spatially, the intensity of robust flavor style, and hay-like, burnt, nutty, woody, pure-sweetness scents of Xiangxi tobacco leaves decreased from north to south; the intensity of burnt-sweetness scent decreased and that of spicy scent increased from east to west.
