摘　　要：百里杜鹃自然保护区位于贵州省西北部高原,是目前世界上最大的天然杜鹃林集中连片分布地之一,面积约125.8km2,但长期以来对其本底杜鹃属植物资源缺乏系统和全面的专题研究。从2007年至2010年,在大量野外调查、标本鉴定、查阅和文献引证的基础上,本研究在该保护区发现了一批新分类群和新记录种,并确认保护区内目前自然分布有杜鹃属植物35种,分属6个亚属、4个组及9个亚组。Located in highland of northwest Guizhou,Nature Reserve of Azalea Forest covers an area of 125.8 km2 and contains one of the largest natural Rhododendron communities in the world. Unfortunately,comprehensive taxonomic studies for the plants there have not been conducted for years. Based on intensive field work,examinations of thousands of specimens and lots of relevant literature from 2007 to 2010,the present study confirms that there are 35 Rhododendron species in the Nature Reserve,including some new taxa and new records which belong to 6 subgenera,4 sections,and 9 subsections,respectively.
