摘 要：
对元江自然保护区内珍稀濒危植物红花木莲群落进行研究,调查了群落物种组成、外貌、演替等,分析了群落的物种多样性。结果表明:(1)群落垂直结构明显,可分为乔木层、灌木层、草本层、层间植物。共有维管束植物110种,隶属47科80属。(2)群落的物种多样性高,草本层的各项物种多样性指数均高于乔木层和灌木层。(3)群落未发展到稳定状态,演替过程中优势种会有所变化。

摘 要：
Manglietia insignis is one of the state-protected three-grade rare and endangered plants. The study is about the community of Manglietia insignis in Yuanjiang Nature Reserve in Yunnan Province. Floristic composition, physiognomy, species diversity and the possible succession of the community are analyzed. Results show that the vertical structure of the community is obvious, which composed of tree, shrub,herb and interlayer plant. There are 110 vascular plant species in the community belonging to 47 families and 80 genera. The community has a high species diversity. The specie diversity indices in herb layer are higher than that in tree layer and shrub layer. The community has not yet developed into a stable state, the dominant species in the succession process may be changed.
