摘　　要：与贵州烟叶化学成分分析及海拔高度相关分析的结果表明，海拔高度是影响烟叶化学成分的重要综合性生态因子，相关性分析结果显示：（1）海拔高度与总糖，还原糖含量呈正相关，达到显著水平（P〈0.05）；（2）烟碱和总氮含量随海拔升高而降低，与海拔高度呈负相关；（3）烤烟氯含量、钾含量和蛋白质含量与海拔高度间无明显的相关性；（4）在海拔1501-2000m种植的烟叶，主要化学成分协调，烟叶可用性高。The relative analysis on altitude and main chemical composition of Guizhou flue-cured tobacco was carried out. The results showed that the altitude was an important factor influenced tobacco chemical composition. There had some conclusions that： （1）the correlations of total sugar and reducing sugar with the altitude was positive（P〈0.05）;（2）the nicotine and total nitrogen were negatively correlated with the altitude（P〈0.05）; （3）the results revealed that the altitude had little effects on the chlorine content, potassium content and protein content; （4）major chemical components was harmony, the usability would be better for flue-cured tobacco in l 501-2 000 in.
