摘要
本文对河南省现生１９ 种两栖动物的地理分布进行了聚类研究。将各种两栖动物在各动物地理省分布的有或无作为二元状态， 用联合系数来表征每两个动物地理省间两栖动物组成的相似程度， 以类平均法进行聚类；论述了河南省两栖动物地理分布的特点， 并对聚类结果与动物地理区划进行了比较。
The amphibians recorded in Henan Province are 19 speices.The fauna and geographical division of Henan have been studied by Qu Wenyuan et al (1995). This paper gives a cluster analysis on geographical distribution of amphibians. The “yes' or “no'(l or 0) of distribution of amphibians in Henan Province were regarded as two components status. The relative coefficient was taken for the similar degree of amphibans in every two zoogeographical province. The cluster analysis was taken by similar method.(To be continued on next page) This paper discusses the characteristics of geographical distribution, gives a comparison between the cluster analysis result and the geographical distribution of amphibians in Henan Province.
