利用秆维管束进行中国散生竹类的聚类分析

本文是应用模糊聚类分析方法研究中国散生竹类分类的一次尝试。分类特征采用了竹秆上、中、下三段各类型维管束数,方法上使用了模糊(Fuzzy)直接聚类分析进行综合分析。经电子计算机运算后,不仅取得了与传统分类基本一致的分类结果,同时也表明这种方法较之其它一些植物数量分类方法简便易行,此外还讨论了一些中国散生竹类分类上的问题。

THE CLUSTER ANALYSIS ON CHINESE BAMBOOS WITH LEPTOMORPH RHIZOMES BY USING THE VASCULAR BUNDLE IN CULM SEGMENTS

This paper deals with the application of the Fuzzy methods in classification of Chinese bamboos with leptomorph rhizomes taxonomical research. Characters of the vascular bundle in bamboo culm segments from 3 different height, the upper, the middle, and the lower, were used. The Fuzzy direct cluster analysing method was used to conduct comprehensive analysis. The classification results being identical with traditional classification was obtained, and this method was proved as well to be much simpler than other numerical taxonomic methods. Besides, some problems in classification of Chinese bamboos with leptomorph rhizomes were discussed.
