摘要: 杜鹃花属(Rhododendron L.)植物是世界著名花卉，全球有1200余种，广泛分布于亚洲、欧洲及北美洲。中国是世界杜鹃花多样性中心和生态中心，目前分布有约600种。贵州境内杜鹃花属植物资源丰富且独具特色，现有约110种。百里杜鹃省级自然保护区是世界杜鹃花属植物最大的集中连片分布区之一，原生性强并保存完整，是贵州野生杜鹃花资源最具特色和代表性的区域。百里杜鹃现有野生杜鹃花属植物约42种，特有种14种，分别属于6个亚属、6个组和9个亚组。本文在前期研究基础上，整理归纳出各分类群的主要鉴别特征，建立了百里杜鹃杜鹃花属植物分类检索表，可为该地区杜鹃花属植物的快速准确鉴别、资源保育及可持续利用提供科学依据。
Abstract: Rhododendrons are stunning ornamental plants with about 1200 species in the world, which are widely distributed in Asia, Europe and North America. China is the distribution center and the most important origin of Rhododendrons in the world, with about 600 species. There are about 110 species of Rhododendron in Guizhou province, which is rich in resources and unique. Baili Rhododendron Provincial Nature Reserve is one of the largest concentrated and contiguous dis-tribution areas of Rhododendron in the world. It is highly primitive and well preserved. It is also the most characteristic and representative area of wild Rhododendrons in Guizhou province. There are about 42 species of Rhododendron and 14 endemic species, belonging to 6 subgenera, 6 sections and 9 subsections respectively. Based on the previous researches, this paper sorted out and summarized an identification key with main diagnostic characters for the genus Rhododendron in the Nature Reserve, which can provide a scientific basis for the accurate identification, resources conservation and sustainable utilization of Rhododendrons in this area.
