| 关 键 字：常绿阔叶林 次生林 群落分析 |
| 摘 要： 鹤山龙口村边次生常绿阔叶林属季风常绿阔叶林类型，其种类组成复杂多样而富于热带性，据１２００ｍ２的样方统计，有维管束植物６２种，分属于３２科、５４属，其中，属热带分布的有３２种，属热带－亚热带分布的有２１种，属亚热带分布的只有７种，其余２种为世界分布。本群落的外貌终年常绿，层次结构复杂而不明显，样地内高于１－５ｍ的立木有５２种１８５７株，灌木层种类和株数尚多，１００ｍ２内有１８５株，草本层以乔灌木幼苗为主，草本植物较少。群落组成结构与地带性常绿阔叶林相似，乔、灌、草各层的物种多样性指数在４左右，群落均匀度为０－７～０－９，生态优势度为０－０７～０－１０，但群落明显具有次生性，大部分优势种群呈集群分布。若能减少人为干扰破坏，本群落将向地带性典型植被类型演替。 |

| 摘 要(英文)：The secondary monsoon evergreen broad-leaf forest at a village of Longkou Town, Heshan City, Guangdong, located at the south edge of sub-tropical zone, is a community of Helicia cochinchinensis, Endospermum chinense, Machilus chinensis and Gironniera subaequalis. A 1 200 m 2 plot of the community consists of 32 families, 54 genera and 62 species, of which 32 species are tropical elements, 21 pan-tropical and 7 sub-tropical, and the others are extensive species. An evergreen appearance and complicated vertical structure are found in the community. There are 1 857 tree individuals which are over 1 5 m in height in the plot, and 185 shrub individuals in the 100 m 2 plot. Most herb species are offspring of trees and shrubs, the true grasses are few. The organization structure of the community is similar to that of the zonal vegetation. The Shannon-Winner index is about 4, the community evenniss 0 7～0 9 and Simpson ecological dominance 0 07～0 10. Most of the dominant population of the community are of clu |
