| 中文摘要: |
| 选择3个具有代表性的广西滨海红鳞蒲桃（Syzygium hancei）群落建立样地，对物种组成及数量进行调查，从群落结构、重要值指数等方面分析红鳞蒲桃群落的多样性特征。分析结果表明，广西滨海红鳞蒲桃群落共有维管束植物73种，隶属于39科66属，其中乔木44种、灌木11种、草本10种、藤本8种。群落中乔木层以红鳞蒲桃为优势，其他建群种为下龙新木姜、岭南山竹子、山油柑、丛花山矾等。灌木层的优势种为下龙新木姜、山油柑、喙果皂帽花等。总体来说，广西滨海红鳞蒲桃群落物种较丰富，乔木层
中红鳞蒲桃占绝对优势，但红鳞蒲桃的优势地位随着群落年龄的增长而递减，且乔木层与灌木层的优势种随着地点的不同而有所差异。 |
| 英文摘要: |
| Based on the investigation of Syzygium hancei community along the coast of guangxi，the
characteristics and distribution mechanism of the species composition were studied，the relationship among different
groups in the community was explored，to provide a scientific basis for the protection and development of S. hancei.
Three representative communities of S. hancei along the coast of guangxi were selected to build plots，the species
and quantity was investigated，the diversity characteristics of S. hancei were analyzed from community structure and
important value index. The results shoued that in the community of S. hancei along the coast of Guangxi，there were
73 plant species，belonging to 39 families and 66 generas，including 44 species of trees，11 species of shrubs，10
species of herbs，8 species of vines. S. hancei was the dominant species in tree layer，other building groups included
Neolitsea alongensis，Garcinia oblongifolia，Acronychia pedunculata，Symplocos poilanei and so on. The dominant
species in shrubs layer included Neolitsea alongensis，Acronychia pedunculata and Dasymaschalon rostratum. The
species was rich in the community of S. hancei along the coast of Guangxi. S. hancei had absolute advantage in tree
layer，but its advantage decreased with age community increasing. The dominant species in tree layer and shrubs
layer were different in different places. |
