Abstract: Based on the meteorological data and physicochemical properties of soil in Lufeng base of China tobacco Jiangsu industrial Co, Ltd , climate feasibility, climate similarity and soil feasibility were analyzed. By analyzing tobacco appearance, chemical components and sensory, comprehensive quality of tobacco leaves were evaluated. The results were as follows:(1) climate feasibility index(CFI) of Lufeng base was 100%. Lufeng base was the most suitable planting area of tobacco. The similarity of the climatic conditions of fluetobacco for other tobaccogrowing areas reached the higher degree. The value of similarity ranged from 0.50 to 0.99. (2) Soil feasibility index of Lufeng base was 0.73. SFI reached 2 class levels, close to 1 class levels, which suggested soil of the region was suitable for planting flue cured tobacco. (3) By analyzing meteorological data of Lufeng base, tobacco flavor index（K value） was 0.26. Tobacco leaves were typical of clear scent. Tobacco leaf structure osteoporosis maturity were better. Quality of aroma was high，undesirable taste and biting taste were small.
