摘要
基于对群落22个样地的调查,以群落样地中乔木层树种的重要值为指标,采用纸条排队法、群落相似系数分类法、最近邻体法和组平均法对格氏栲自然保护区常绿阔叶林群落进行数量分类。结果表明:4种分类结果基本相似,格氏栲自然保护区常绿阔叶林群落样地可分为格氏栲群系、米槠群系、甜槠群系、刨花楠群系、沉水樟群系、观光木群系和闽楠群系等7个群系,并论述了各群系的群落学特征,各群系基本处于稳定的顶极阶段。
A survey was carded at 22 sites in in Castanopsis kawakamii Nature Reserve based on the important values of species in tree layer.. Four quantitative classification methods were used to classify the evergreen broadleaved forest community, including the tabular comparison of data, the tabular comparison of similarity coefficient, the nearest method and the group-average method of hierarchical agglomerative classification. Results showed that there were no differences in the classification among 4 methods. The evergreen broadleaved forest community in Castanopsis kawakamii Nature Reserve can be divided into 7 formations, i.e. Castanopsis kawakamii, Castanopsis carlesii, Castanopsis eyrei, Machilus pauhoi, Cinnamomum micranthum, Tsoongiodendron odorum and Tsoongiodendron odorum formations. The characteristics of each formation was described in the paper. Results suggested all formations of the evergreen broadleaved forest community were at their climax stages in Castanopsis kawakamii Nature Reserve..
