摘　　要：在GIS(Geographic Information System)平台上,利用统计分析软件SPSS(Statistical Program for Social Science)的主成分分析和动态逐步聚类方法对湖北省植烟区进行了生态气候类型区划试验。结果表明,湖北省植烟区可划分为四大类:第一类是以十堰市为主的环神农架植烟区;第二类是以恩施为核心的鄂西南地区;第三类是神农架地区;第四类是以襄阳和宜昌为核心的鄂西北地区。同时简要评述了各类植烟区的特征特性。The eco-climatc regionalization of tobacco growing areas in Hubei Province was carried out with the principal component analysis and dynamic stepwise cluster analysis of SPSS （Statistical Program for Social Science） software on a GIS platform. The results showed that the tobacco growing areas in Hubei could be divided into four categories： Category ｜ was the areas surrounding Shennongjia, mainly including Shiyan; Category Ⅱ included areas in the southwest of Hubei around Enshi; Category Ⅲ was Shennongjia region; and Category IV was the areas in the northwest of Hubei mainly including Xiangyang and Yichang. The characteristics of each category were briefly commented.
