浙江丽水太山山地常绿阔叶林的群落特征

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常绿阔叶林群落类型进行了分析。结果表明,太山山地常绿阔叶林主要有3种类型(群系),即甜槠木荷林、褐叶青冈林、青冈石栎林。并对各群落类型的结构和物种组成进行了分析。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次降低,群落类型处于华东和华南区系的过渡带。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。

The Community Characteristics of Evergreen Broad-Leaved Forest in Taishan Mountain in Lishui of Zhejiang

Through plot investigation.Plant diversity of the Evergreen broad-leaved forest in Taishan mountain of Lishui in Zhejiang provcince was determined and analyzed by using the index of species richness,species diversity and community evenness.The results showed that there were 3types (Formation) of evergreen broad-leaved forests in the reserve: a Form.Schima superba-Castanopsis eyrei,a Form.Cyclobalanopsis glauca- Lithocarpus glaber and a Form. Cyclobalanopsis stewardiana.The structure and floristic components of the communities were described.In the vertical structure of community,the species diversity of shrub layer was the highest,and decrease layerd from shrub,tree to herb layer.Taishan Mountain has also showed the transitional characteristics between the flora of E.China and that of S.China. The evergreen broad-leaved was characterized by evergreen mesophanerophytes and microphanerophytes with simple,leathery and entire microphyllous leaves.
