数值分类在藓类植物中的应用

根据数值分类学的基本原理,设计了一个实现藓类植物数值分类的算法,通过该算法对33种藓类植物孢子和孢蒴的主要性状进行了计算机数量化分析,根据距离系数验证了它们之间的相似性和区别,并与形态和细胞分类作了比较,从数值分类角度可以说明大帽藓属（Encalypta）、真藓属（Bryum）和金发藓属（Polytrichum）是属级的自然分类群,小金发藓属（Pogonatum）与金发藓属（Polytrichum）是科一级的自然分类群,有2个物种与所在属的其它物种距离系数相差相关稍大,原因有待进一步探讨。

Application of Numeral Taxonomy in Moss

An the algorithm to achieve numeral value classification of moss is designed according to foundational principle of numeral taxonomy.The numeral characters of spores and capsule on 33 taxon in moss are analysed by computer.Not only similarity and difference are tested on the basis of their distance coefficient but also coimpared with form and classification.The analytical results show that Encalypta,Bryum and Polytrichum belongs to natural groups of genus level, Pogonatum and Polytrichum belongs to natural groups of family level.The distance coefficient of two species are bigger than other species.It is needful to research the cause.
