摘要: 用物种多样性指数(Simpson指数和Shannon指数)、均匀度指数(Pielou均匀度)和物种丰富度,对佛坪国家级自然保护区主要高等植物群落物种多样性进行了测度。结果表明:森林群落的多样性程度高于灌丛和草甸,落叶阔叶林高于针叶林,栎林高于杨桦林。群落物种多样性有随海拔高度的升高而降低的趋势。物种多样性在森林群落垂直结构上的分布特点,表现为一般乔木层与灌木层接近但低于草本层。

AbstractThe species diversity of higher plant communities in Foping National Reserve was measured with species diversity index(Simpson index and Shannon index),Pielou's eventless index and species richness.The result shows that the diversity 0f forest cemmunities is higher than that 0f shrubs and meadow communities,the divesity 0f the deciduous broad-leaved forest is higher than that of coniferous forest,and that of oak forest is higher than that of popular and birch forest.The species diversity of higher plant communities decreases with the increase of elevation.The spcies diversity indices and evenness indices for different layers in forest communities show that the tree layer has similar divetslty and evenness with the shrub layer,while the herbaceous layer has higher diversity and evenness than both 0f the tree and the shrub layers.
