摘要(Abstract)：

稀果杜鹃是贵州梵净山山顶杜鹃灌丛群丛特色物种之一,是构成梵净山杜鹃长廊景点的关键物种。采用常规群落生态学调查,对梵净山稀果杜鹃群落的种类组成、物种多样性及群落结构进行了研究,结果表明:在600 m2的样地中,共有维管植物15科25属27种,灌木层中稀果杜鹃重要值最高;物种多样性特征分析显示该群落多样性指数偏低,灌木层中优势种明显,物种分布随机性大,草本层物种较少,分布较均匀;群落垂直结构简单,高度集中在3～3.5 m,群落垂直结构稳定。
Rhododendron oligocarpum is one of the characteristic species of Rhododendron shrub clusters on the top of Mount. Fanjing in Guizhou Province, and it is the key species of that constitutes the scenic spot of the Rhododendron corridor in Mount. Fanjing. The species composition, species diversity, and community structure of Rhododendron oligocarpum in Mount Fanjing were studied by conventional community ecology investigation. The results showed that there were 27 species of vascular plants belonging to 25 genera and 15 families in the 600 m2 sampled plot, and the important value of Rhododendron oligocarpum was the highest in shrub layer. The species diversity analysis showed that community diversity index was low, the dominant species were obvious and the distribution of species was random in the shrub layer, the species were few and the distribution was more uniform in the herbaceous layer. The vertical structure of the community was simple, with a height of 3 to 3.5 meters, and the vertical structure of the community was stable.
