摘要
对广东省49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,用结合系数来表征每两个动物地理省同两栖动物组成的相似程度,以类平均法进行聚类。聚类结果表明两栖类在广东各动物地理省的分布受地形明显影响。论述了广东省两辆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。
This paper gives a cluster analysis on geographical distribution of amphibians in Guangdong Province. The ＂yes＂ or ＂no＂ （1 or 0） of distribution of amphibians in Guangdong Province were regarded as two-state character. The relative coefficient was taken for the similar degree of amphibians in ever two zoogeographical provinces. The cluster analysis was taken by group average method. The characteristics of geographical distribution and the comparison between the duster analysis resuh and the geographical distribution of amphibians in Guangdong Province are discussed.
