| 摘 要： | 本文采用样方调查的方法，对湖南阳明山国家森林公园黄杉保护区内海通植物群落的乔木层进行调查，运用多样性指数，对其群落的组成、结构特征及物种多样性进行了研究，结果表明：该群落内乔木类植物共有12科13属14种，马鞭草科、壳斗科、槭树科、樟科为该群落主要组成科；物种的区系分布较集中，主要为在热带亚洲分布和北温带分布，具有一定的过渡性；该群落以小高位芽植物（72．27％）占优势，叶级以微型叶为主（42．85％），叶片特征以单叶（78．57％）、革质叶（42．85％）为主；通过重要值的分析可知，海通在该群落内具有绝对的优势，但这也造成物种的单一性，不利于群落内部的系统稳定性。

| Abstract: | Using the method of sample plots, the community of Clerodendrum Mandarionorum which in National Nature Reserve of Yangming Mountain were investigated and holding diversity index,the community composition, structure and species diversity were studied. The results showed that：There is 12 sections 13 categories and 14 species of arbor layer in this community, the main divisions are Verbenaceae .Fagaceae .Aceraceae,Lauraceae;the compositions of the community are concentrated, with the characteristics of transition from the tropical Asia to northern of temperate zone; the Microphanerophyte （72.27 %） is dominant, Nanophyll （42.85 % ）is the main leaf size ; Single （78.57 % ） and Coriaceous（42.85 %）are the main leaves;through analysis about the important value,we can see that the Clerodendrum Mandarionorum has the absolute advantage,however this phenomenon lead to the species so single that the community lack of stability. |
