摘　　要：根据遵义市地形地貌和气候因素等条件,选择用坡度、光照、温度、日照时长作为遵义烟区区域划分的指标。通过聚类分析,以大娄山为界全市10个种烟县可以分为两大片区,即桐梓、正安、道真、务川、仁怀、绥阳等县北部山地烟区和遵义、湄潭、凤冈、余庆等县的南部丘原烟区。北部山地烟区位于大娄山北部,地貌以中山峡谷为主,大部分地区海拔高度在900～1500m之间,梯田台地比重较大;年日照时数1050～1150h,年均温为14～16℃,年降水量1050～1200mm。南部丘原烟区位于大娄山南部,地貌以低山丘陵、山间谷坝和宽谷盆地为主,海拔高度一般在800～1000m,地势较为平坦;年日照时数1100～1200h;年均温15～16.5℃,年均降雨量1000～1300mm。遵义烟区烟叶质量风格特色在香气类型上总体以中间香型为主,偏清香类型为次;北部山地烟区以偏清香类型为主,南部丘原烟区以中间香型为主。Based on topographical, climatic, and other conditions in Zunyi, gradient, sunlight, temperature, and sunshine duration were used as parameters to classify the tobacco ecotypic areas in Zunyi. Cluster analysis result indicated that Zunyi tobacco region with 10 tobacco planting counties could be divided into two ecotypic aeras by Dalou Mountain as a boundary. The northem mountainous tobacco area contained Tongzi, Zhengan, Daozhen, Wuchuan, Renhuai and Suiyang county; while the southern highland tobacco area included Zunyi, Meitan, Fenggang, and Yuqing county. Northern mountainous tobacco area lie on the north of Dalou mountain, largely middle mountains and canyons with much terraced land and mesa, altitude is between 900-1 500 m, average sunshine duration per year is 1 050-1 150 h, average temperature per year is 14-16℃, average rainfall per year is 1 050-1 200 mm. Southern highland tobacco area lie on the south of Dalou mountain, landform is hill, valley, and basins, altitude is between 800-1 000 m, average sunshine duration per year is 1 000-1 200 h, average temperature per year is 15-16.5℃, average rainfall per year is 1 050-1 300 mm. Tobacco leaf in Zunyi has two styles, middle-scent is primary and faint-scent is secondary. Southern highland tobacco area belong to the former and northern mountainous tobacco area belong to the latter.
