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。

关 键 词:佛坪自然保护区  植被  物种多样性  丰富度  均匀度

Abstract:The species diversity of higher plant communities in Foping National Reserve was measured withspecies diversity index (Simpson index and Shannon index), Pielou's evennes index and species richness. Theresult shows that the diversity of forest communities is higher than that of shruba and meadow communities,the diversity of the deciduous broad-leaved forest is higher than that of coniferous forest, and that of oak forestis higher than that of popular and birch forest. The species diversity of higher plant communities decreaseswith the increase of elevation. The species diversity indices and evenness indices for different layers in forestcommunities show that the tree layer has similar species diversity and evenness with the shrub layer, while theherbaceous layer has higher diversity and evenness than boh of the tree and the shrub layers.
Keywords:Foping National Reserve  vegetation  species diversity  richness  evenness
