Forty-four leaf tobacco samples from Hunan province were collected and tested by sensory evaluation to study regional distribution characteristics of flavor types and notes. Spatial distribution of various flavors and aroma scales was drawn by inverse distance weighting (IDW) method. Results showed that:1) strong flavor type was from little to prominent, with hay incense, burnt sweetness aroma and burnt aroma as the principal notes. 2) significant differences were found between strong flavor type and burnt-sweetness type among different regions, with non-significant differences for hay incense, pure-sweetness aroma, nutty aroma, burnt aroma and spicy flavor. 3) IDW map indicated that scales of strong flavor type, burnt-sweetness aroma, burnt aroma and spicy flavor decreased from south to north, and the same for hay incense from northwest to south, and for pure-sweetness aroma from west to east. Nutty aroma and woody aroma were distributed in spots.%为明确湖南烟叶的香型和香韵区域分布特征，对来自湖南烟区的44个烟叶样品进行了感官评价。结果表明：①湖南烟叶浓香型风格尚显著至较显著；香韵以干草香、焦甜香与焦香为主。②不同地区之间浓香型和焦甜香差异显著，干草香、正甜香、坚果香、焦香、辛香差异不显著。③浓香型、焦甜香、焦香、辛香有从南部向北部递减的分布趋势，干草香有从西北部向南部递减的分布趋势，正甜香有从西部东南部递减的分布趋势，木香、坚果香呈斑块状分布。
