摘　　要：通过文献查阅掌握贵州省野生杜鹃花属植物在县域单元上的分布情况,运用Dobson筛除算法分析贵州省野生杜鹃花属植物的分布热点县域单元。结果表明:贵州省野生杜鹃花属植物有5亚属164种(含变种和亚种),存在百里杜鹃管理区、江口县和威宁自治县等24个分布热点县域单元,其中黔西北百里杜鹃管理区的物种丰富度最高。此外,贵州杜鹃花属植物在划定有保护区的县域单元物种丰富度也较高,可见其分布的热点县域单元同时也是贵州生物多样性的丰富区和关键区。对热点分布县域单元加强生态环境保护,在有效保护目标物种时,也能使其他生物及其共有的生态系统和栖息地得到保护。A literature review was presented on the distribution of wild Rhododendron in the counties of Guizhou Province.The distribution hotspots of wild Rhododendron were also analyzed using Dobson screening.The results showed that there were 164 species(including varieties and subspecies)under five sub genera of wild Rhododendron in the study area.A total of 24 hotspots countries were screened after optimization,such as Bailidujuan management area,Jiangkou,and Weining.The highest richness of species was then found in the northwestern Bailidujuan management area.In addition,the high richness of Rhododendron species was also observed in the county with the protected areas.Therefore,the hotspots countries were distributed the same as the rich and key areas of biodiversity.In summary,the ecological environment should be effectively protected for the target species,organisms,as well as their ecosystems and habitats in the hotspot countries.
