摘　　要：为了明确恩施烟区烟叶品质与海拔高度关系,在恩施烟区海拔540～1 680 m范围内,对中部烟叶主要化学成分和感官评吸质量与海拔高度之间的相关性进行分析。结果表明,各主要化学成分指标及其派生值与海拔高度的相关性均未达显著水平,而化学成分协调性得分则与海拔高度呈显著负相关;烟叶评吸总分以及香气质、刺激性、香气量、杂气和余味得分与海拔高度呈极显著或显著正相关,而燃烧性和灰色得分与海拔高度不存在相关关系。回归分析表明,随着海拔高度的升高,烟叶化学成分的协调性降低,而感官评吸质量逐渐提高。The paper aims to clarify the relationship between tobacco quality and altitude in Enshi.The correlations of main chemical constituents and sensory quality of the central tobacco leaves with the altitudes were analyzed within the altitude of 540~1 680 m in Enshi.The results showed that the correlation of the main chemical composition indexes and their derived values with the altitude was not significant,while the score for the coordination of main chemical components of tobacco leaves was negatively related to the altitude.The total score of smoking as well as the scores for the quality of aroma,irritation,volume of aroma,miscellaneous gas and aftertaste were very significantly or significantly positively correlated with the altitude,but there was no correlation between combustibility or grey score and the altitude.Regression analysis showed that the coordination of chemical components of tobacco leaves decreased with the increase of altitude,while the sensory evaluation quality gradually increased.
