摘要: 本文应用聚类、极点排序、主分量分析等多元分析方法,对香港岛的森林群落进行了分类与排序。根据组平均法、离差平方和法、最近邻体法等三种聚类分析的结果,香港岛的森林群落可划分为三个植被亚型和七个群系。极点排序较好地反映了植被的连续性,以及群落所在地的海拔、干湿程度、土壤类型等生境条件的梯度变化,主分量分析表示出13个森林群落的相互关系,可以从原来60个彼此相关的变量降为13个互相独立的变量。主分量分析的二维排序图较好地划分出南亚热带常绿阔叶林为低地林,低山林和山地林等三个植被亚型。

Abstract:
Three kinds of multivariate analysis, the cluster, the polar ordination, and the principal components analyses, were used to deal with the forest communities on Hong Kong Island.From the results of cluster analyses, the lower subtropical evergreen broadleaved forests on Hong Kong Island were divided into three sub-types and seven formations.The result of polar ordination showed finely the continnum of Hong Kong Island vegetation and the gradient of the change of the habitat conditions. In the aspect of communities classification, it almost has the same results as that of cluster analyses .The principal components analysis showed that the relationship among 13 communities, which was expressed before with 60 dependent variates, could be expressed with 13 independent variates .
