摘  要：
栲属植物是我国东部常绿阔叶林的主要组成树种。在进行宁波市森林资源调查中发现宁海南溪村有钩栲(Castanopsis tibetana)天然分布,采用标准样地法进行群落学调查,分析了钩栲群落结构及其主要组成树种的更新类型。结果表明:钩栲是群落最大优势种,林木层中出现木本植物23科45种;5种种群结构类型:单峰型、单柱型、间歇型、L字型和逆J字型。逆J字型的钩栲和甜槠(C.eyrei)通过幼苗和萌枝2种更新方式维持其在群落中的优势地位。群落已进入常绿阔叶林演替阶段,但还处于前期。由于地理位置和群落结构的差异,现有钩栲群落种类组成存在差异。

摘  要：
Castanopsisis the main tree species of evergreen broadleaved forest(BEF)in east China.In Nanxi village,northwest of Ninghai,the natural distribution of Castanopsis tibetana was found during forest resource survey.To determine the structure and regeneration types of the main species of C.tibetanacommunity,all wood species within standard sampling plots were identified and measured.The results indicated that C.tibetana was the dominant species in the community.Forty-five species of plants,belonging to 23 families,were recorded in the wood layer.The regeneration of woody species was categorized into five types:unimodal,unibar,sporadic,L and inverse-J types.C.tibetanaand C.eyrei were within the category of inverse-J type,which regenerated through new stems and sprouts,and were long-lived dominant wood species in the community.The succession stage of this forest was classified as late seral community stage which would develop into a climax community.For the geographical location and community structure,the species composition was different between this C.tibetanacommunity and others.
