| 摘 要： | 以4个红鳞蒲桃（Syzygium hancei）群落调查为基础,从种群特征、不同群落类型、重要值指数、层次的丰富度、均匀度和物种多样性指数等方面分析广西滨海过渡带红鳞蒲桃群落多样性。广西滨海过渡带红鳞蒲桃种群的平均高度为（11.64±2.51）m,平均胸径为（23.00±10.73）cm。群落植物生长型与群落多样性指数的关系表现为乔木层物种丰富度指数明显低于灌木层,乔木层和灌木层的均匀度指数相近,群落间变异幅度较小,灌木层则变异幅度稍大。物种多样性指数则表现出灌木层〉乔木层的规律。

| Abstract: | Based on the data of four Syzygium hancei sample plots,the species diversity of Syzygium hancei in coastal ecotone of Guangxi was discussed from the aspects of population characters,different community type,importance value index,species richness,evenness and species diversity.The results indicated that the average height and DBH of Syzygium hancei population are(11.64±2.51)m and(23.00±10.73)cm.The species richness of arbor layer is obviously lower than shrub layer,their evenness is close,and variation of communities is small,but variation of shrub layer is bigger.And species diversity index of shrub layer is bigger than that of arbor layer. |
