摘　　要：在样方调查的基础上,对东山岛海岸带潺槁树天然林的群落结构进行了研究,结果表明:所调查群落属于南亚热带次生季风常绿阔叶林,在3 600 m2的样地中共有植物36科43属78种,多为单属单种,且层次性较强,可分为乔木层、灌木层、藤本层和草本层4层.群落A乔木层中潺槁树的重要值最大,群落B和群落C乔木层中潺槁树的重要值列第三,灌木层中潺槁树的重要值皆最大.3个群落中潺槁树的径级结构皆呈进展型,物种多样性比较结果显示,潺槁树天然林的物种多样性与群落所处位置、人为干扰程度和保护时间等呈明显相关,其排序为群落A>群落B>群落C,强度的人为干扰将导致多样性的降低.研究结果为潺槁树天然林的保护和恢复提供了早期研究基础.The community characters of coastal Litsea glutinosa natural forest on Dongshan Island were studied based on community investigation,and the results indicated that there were 78 species in 80 genera and 44 families of plants in plots of 3 600 m2.The layers of arbors,shrubs,liane,and herbages could be distinguished clearly.The importance value of Litsea glutinosa was the highest in tree layer of community A,and was the third in tree layer of community B and community C,while it was the highest in shrub layer of 3 communities.The DBH class structure of Litsea glutinosa in 3 communities were all at the up-growth stage.Diversity comparison showed that the diversity of Litsea glutinosa community was correlated with the position,disturbance and the time of protection,and the diversity was community A community B community C.The results provided fundamental data for the protection and re-establishment of Litsea glutinosa natural forest at the early research stage.
