| 摘 要： | 对文成县石垟林场常绿阔叶林的不同样地、不同层次的物种丰富度、物种多样性指数和群落均匀度进行了分析,结果表明:在群落垂直结构中,乔木层第2亚层的物种丰富度、物种多样性指数、群落均匀度显著大于第1亚层.乔木层与灌木层之间多样性各项指标总体无显著差别.乔木层、灌木层的物种丰富度、物种多样性指数均大于草本层,且差异极显著,群落均匀度差异显著.乔木层、灌木层、草本层的多样性各项指标在群落各样地间均有一定的差异,相对而言,灌木层、乔木层的差异较小,草本层的差异较大.

| Abstract: | Analysis on the species richness and diversity index, community evenness in different plots and layers of evergreen broad-leaved forest in Shiyang Forest Center in Wencheng, Zhejiang province resulted that species richness and diversity index, community evenness of the second sublayer of tree layer was much greater than that of the first sublayer in the vertical structure of the community. There was no significant difference of diversity index between the tree layer and the shrub layer. The species richness and diversity index of the tree layer and the shrub layer was obviously higher than that of the herb layer, and their evenness had evident difference. The diversity indexes of tree, shrub and herb layer in various plots had a little difference. |
