摘要
基于广东南澳岛中华楠Machilus chinensis群落调查,分析了群落的结构特征、物种多样性和种间相关性.结果表明,1 400 m2的样地中,共有维管束植物45种,隶属29科39属.群落的主要优势树种为中华楠、台湾相思Acaciaconfusa、鸭脚木Schefflera octophylla,整个群落的Shannon-Wiener多样性指数、Margalef丰富度指数及Pielou均匀度指数均表现为灌木层>乔木层>草本层.16个乔木层优势树种的Pearson相关系数检验中有9个种对存在显著相关.
Based on the data collected from the sampling plot in Nan＇ao Island,this paper analyzed the structure,diversity and interspecific correlation of the Machilus chinensis community.The results showed that there were 45 species of vascular plants belonging to 39 genera and 29 families in 1 400 m2 plots.Machilus chinensis,Acacia confusa and Schefflera octophylla were the dominant tree species.The Shannon-Wiener diversity index,Margalef richness index and Pielou evenness index of the community showed shrub layertree layerherb layer.There were 9 species pairs showing significant correlation in 16 dominant tree species.
