摘要： 为了掌握湖南省烟叶品质类型的空间分布情况，选取影响湖南烟叶品质形成的6个气候因子，利用主成分分析和聚类分析相结合的方法，对湖南烟叶种植区进行了烟叶品质气候分型，讨论各烟叶品质气候类型的气候差异性和气候特点，并进行湖南烟叶品质气候区划。结果表明：湖南烟叶品质可划分为3类品质气候区，Ⅰ类品质气候区分布在湘西，具有大田期热量资源丰富，成熟期日照充裕，昼夜温差大、成熟期后期雨水较少的气候特征；Ⅱ类品质气候区主要分布在湘中一带，具有大田期热量资源适宜，成熟期日照较多，昼夜温差大，高温热害发生机率较高的气候特征；Ⅲ类品质气候区主要分布在湘南南部和湘东北等地，具有大田期热量资源适宜、成熟期日照较少、昼夜温差较大、高温热害发生机率较低的气候特征。

Abstract: In order to grasp the spatial distribution of tobacco-quality types in Hunan, based on the 6 climatic factors affecting tobacco quality, the tobacco planting area in Hunan was divided into several climatic types of tobacco quality by using of principal component analysis method and clustering analysis method. At the same time, the climatic difference and characteristics of several tobacco- quality climatic types were discussed and the tobacco-quality climatic types of Hunan were divided. The results showed that the tobacco-quality climatic types of Hunan were divided into 3 types. ClassⅠclimatic region was located in western Hunan and its climate was characterized by rich heat resources of field period, abundant mature sunshine, large temperature difference between day and night, less precipitations of mature late. ClassⅡclimatic region was mainly located in central Hunan and its climate was characterized by suitable heat resources of field period, more sunshine of mature stage, high temperature difference between day and night, high temperature damage probability higher. ClassⅢclimatic region was mainly located in south of southern Hunan and northeastern Hunan and its climate was characterized by suitable heat resources of field period, less sunshine of mature stage, high temperature difference between day and night, high temperature damage probability lower.
