查询词典 distribution coefficient

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.
