Soil plays an important role in highlighting the aroma style of tobacco leaves. Soil series is lowest classification unit of soil taxonomy and is the holographic ID card of soil. Hunan is one of the main tobacco-planting provinces, this paper took Jianghua and Guiyang in southern Hunan (region of full-aroma type of flue-cured tobacco) and Jinzhou, Fenghuang and Shangzhi in western Hunan (region of middle-scent type of flue-cured tobacco) as the study regions, selected totally 35 typical tobacco fields which could grow the tobacco leaves of the highest-quality and tried to establish preliminarily the relevant soil series. The results showed that: 1) the 35 typical tobacco field soils could be classified into 4 orders (Anthrosols, Ferrosols, Argosols and Cambosols), 4 suborders, 9 groups, 14 subgroups, 17 families and 27 series. 2) Soils of southern Hunan usually showed calcareous property while soils of western Hunan didn’t show calcareous property, which suggested calcareous property of soil may be one of the important factors in forming the full-aroma type of flue-cured tobacco.
