摘 要:通过样方调查,应用物种丰富度、物种多样性指数和群落均匀度等指标对分布在浙江丽水太山山地的褐叶青冈林群落类型进行了分析.结果表明:太山山地褐叶青冈林物种丰富;乔木层优势种群明显,树高分布主要以近似对称分布为主,群落乔木层个体高度的分布较为均匀;在群落的垂直结构上,灌木层、乔木层、草本层的物种多样性依此降低,灌木层的物种丰富度和物种多样性指数最大;在各样方中,乔木层、灌木层和草本层的物种多样性没有明显的变化趋势;群落生活型以中、小高位芽植物为主,群落叶的性质以单叶、革质和全缘的小叶为主;群落优势种群年龄结构和群落类型属于衰退型.Based on the data of the community structure and species diversity of Form. Cyclobalanopsis stewardiana of Taishan Mountain inLishui, Zhejiang, 40 species in tree layer, 72 in shrub layer and 27 in herb layer were recorded in 10 plots. The structure characteristics of different communities, plant species richness and diversity indicated by Shannon-Wiener index in tree, shrub and herb layer were analyzed. By describing the structure and floristic components of the communities, the results were summarized as follows. In the vertical structure of community, the species diversity of shrub layer was the highest and then decreased from shrub layer to tree and to herb. Plant diversity did not change greatly for tree layer, shrub layer and herb layer with different plots. Whether in tree layer, shrub layer or herb layer, species richness and diversity show no remarkable change for different plo:s. The evergreen broad-leaved was characterized by evergreen mesophanerophytes and microphanerophytes with simple, leathery and entire microphyllous leaves. The age structure and community type of Form. Cyclobalanopsis stewardiana was on the decline,
