| 摘 要： | 应用模糊聚类、相互平均排序及R型主分量分析,对香港岛13个森林群落及其组成物种进一步研究的结果表明:模糊聚类是一种可行的数值分类方法;二维的相互平均排序能很好地反映各森林群落间的相互关系,以及各物种在森林群落中的分布关系;R型主分量分析则能直观地表明香港岛森林群落中优势种与伴生种之间的相互关系.

| Abstract: | A further research was made to the 13 forest communities on Hong Kong island by using fuzzy cluster, reciprocal averaging (RA) and R-Principal component analysis (R-PCA). The results show that fuzzy cluster is suitable for the classfication of the lower subtropical forests, especially, the higher classficational units. The RA ordination indicates the relations between 13 forest communities and 60 species distribution in these forest communities and it seems better and more significant than the other methods in this field. And R-PCA illustrated the relationship between the dominant and subordinate species. |
