广东爬行动物地理分布的聚类分析

Cluster Analysis on Geographical Distribution of Reptiles in Guangdong Province

对广东省83种爬行动物的地理分布进行了聚类研究。将各种爬行动物在广东4个动物地理省(粤北、粤东、粤西、沿海)分布的有或无作为二元性状,用联合系数来表征每两个动物地理省爬行动物组成的相似程度,以类平均法进行聚类分析,结果表明爬行类在广东各动物地理省的分布受地形明显影响,论述了广东省爬行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 reptiles in Guangdong Province. The＂ yes＂ or＂ no＂ （ 1 or 0） of distribution of reptiles in Guangdong Province were regarded as two-state character. The relative coefficient was taken for the similar degree of reptiles in every two zoogeographical provinces. The cluster analysis was taken by group average method. The characteristics of geographical distribution and the comparison between the result of cluster analysis and the geographical distribution of reptiles in Guangdong Province are discussed.
