Title: Cluster Analysis on Geographical Distribution of Amphibians in Yunnan Province
Abstract: To quantify the comparability of geographical distribution pattern of amphibians in Yunnan Province,the geographical distribution of 102 amphibians were regarded as two-state character and classified.The association coefficient was taken for the similar degree of amphibians in every two zoogeographical zones.The cluster analysis was taken by group average method.The result indicates that amphibians in Yunnan Province could be classified into two groups,and there was higher similarity between the boarding zones.The distribution pattern of amphibians varies as the laddering change of hypsography.As the effect of terrain,river,lake and climate,the variational regulation of the distribution as the latitude change was not so obvious.There is significant difference between northern and southern.Finally,the characteristics of geographical distribution pattern and the comparison between the cluster analysis result and the geographical division are discussed on the bases of results.
