在恩施烟区海拔500～1 600m范围内,对烟叶主要化学成分与海拔高度之间的相关性进行分析,结果表明:还原糖、总糖与海拔高度呈正相关,总植物碱与海拔高度负相关；海拔对不同部位烟叶化学成分的影响为中上部大于下部；800～1400m的中海拔烟叶化学成分协调性最好.%The correlations between altitudes and chemical constituents in leaves of tobacco were analyzed within the altitude of 500-1 600 m in Enshi. The results showed that the total sugar and reducing sugar content of tobacco leaves were positively related to the altitude, but the correlation between total alkaloids and altitudes was negative, and these effects were more in the upper and middle leaf than the lower leaf. In 800-1 400 m growing areas, most harmonic chemical components in tobacco leaves were found, thus the high quality tobacco leaves.
