浙江凤阳山自然保护区福建柏群落物种多样性

对浙江省凤阳山自然保护区福建柏Fokienia hodginsii群落的不同样地、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:木本植物的物种丰富度(161种)和物种多样性指数明显大于草本植物(14种),而群落均匀度两者无显著差异。在群落垂直结构中,灌木层的物种丰富度指数、物种多样性指数和群落均匀度均大于乔木层,但两者之间差异不显著。乔木层和灌木层的物种丰富度和物种多样性指数均明显大于草本层。而乔木层、灌木层与草本层之间的群落均匀度差异不显著。表4参29

Species diversity of Fokienia hodginsii community in Nature Reserve of Mount Fengyang in Zhejiang Province

The species richness index,species diversity index and community evenness in different plots and layers of Fokienia hodginsii community in Nature Reserve of Mount Fengyang,Zhejiang Province were analysed.The species richness(161species)and species diversity index of woody plants were obviously bigger than those of herb(14species).Their community evenness had slight different significance.In the vertical structure of community,the species richness,species diversity index and community evenness of the shrub layer were greater than those of the tree layer.The various indexes of diversity between the tree layer and the shrub layer had slight differences.The species richness and species diversity index of the tree layer and shrub layer were obviously bigger than those of the herb layer.It was not very different from those between tree layer and shrub layer and herb layer.Ch,4tab.29ref.]
