【摘要】 从蚤类定量分布角度，将云南现有的１４０种和亚种蚤在５个动物地理小区中以存在或不存在作二元属性状态分布，以联合系数来表征两动物地理小区间蚤类种群组成的相似性程度；以距离系数类平均法进行系统聚类。根据聚类结果显示，云南蚤类的现行动物地理区划与聚类分析基本一致，蚤类的分布显著地受自然地理区位和特定的自然景观所制约更多还原

【Abstract】 According to the number of flea distribution, 140 species and subspecies located in Yunnan were analyzed by distance coefficient average clustering at binary attributes distribution of 5 zoogeographical infra-regions, through union coefficient measuring the similarity of flea composed between zoogeographical infra-regions. The result shows that Yunnan flea zoogeographical divisions is the same as the cluster analysis, and the distribution of flea is notably restricted by natural geographical location and special landscape.更多还原
