| 摘 要： | 乐昌含笑是中国特有珍稀濒危植物,天然群落稀少.首次对乐昌含笑群落特征进行了探讨.结果表明:乐昌含笑群落组成的植物种类丰富,地理成分多样,来源于12个地理分布型,区系特征过渡性明显,群落生活型,具有以中高位植物为主的中亚热带地区的典型,在乔木各层片的群落结构中,乐昌含笑的重要值高达159.55,占有明显的优势地位;通过乐昌含笑种群动态分析得知,该群落正处在相对稳定的演替阶段,建议对本群落采取有效的保护措施.

| Abstract: | Michelia chapensis is a rare and endangered tree species; its natural communities are scarce. This paper discusses Michlia chapensis communities' geographical composition, regional features, community appearance, and structure and population dynamics. The results show that Michelia chapensis species is rich, its geographical composition much diversified, its source in 12 geographical distribution types, its regional features obviously transitional, its live communities in a middle and high position but typical of the area of subtropical zone. Among the communities of arbor layers, the important value of Michelia chapensis is as high as 159.55, possessing an obviously advantageous position. It is known from the analysis of the dynamics of Michelia chapensis population that this community is being in a relatively steady succession stage and needs effective protection. |
