浙江丽水太山山地常绿阔叶林的物种多样性

通过样方调查,应用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的物种多样性进行了研究。结果表明,常绿阔叶林群落乔木种类较为单一,物种多样性和均匀性在群落不同层次中差别较大,灌木层的物种数量和物种多样性指数最大,乔木层次之,草本层最小,灌木层-乔木层-草本层的物种多样性依此递减。根据分布生境,群落结构和种类组成,可将该山地常绿阔叶林分为3个类型(群系),即木荷甜槠林、青冈石栎林和褐叶青冈林。

Plant species diversity of evergreen broadleaf forests in Taishan Mountain of Lishui, Zhejiang Provcince

Through plot investigation and by using the indices of species diversity and community evenness,this paper analyzed the plant diversity of evergreen broadleaf forests in Taishan Mountain of Lishui,Zhejiang Province.The results showed that the species number of arbor in the evergreen broadleaf forest community was in simplification,and the species diversity and evenness varied among different community layers.The species diversity index of shrub layer was the highest,followed by arbor layer,and herb layer.Based on the habitat,community structure and species composition,three main community types i.e.,Schima superba-Castanopsis eyrei,Cyclobalanopsis glauca-Lithocarpus glaber,and Cyclobalanopsis stewardiana were recognized.
