摘　　要：目的分析云南省25县(市)现有的112种医学革螨的动物地理区划。方法用系统聚类方法将云南省25县(市)现有的112种医学革螨在5个动物地理小区的分布作定量分析,以存在或不存在作二元属性状态分布,用联合系数来表征两动物地理小区间医学革螨种群的相似程度;用距离系数类平均法进行系统聚类。结果云南省25县(市)现有的112种医学革螨划分为5个动物地理小区,5个动物地理小区的划分与聚类分析结果基本相符。结论云南省医学革螨的分布显著地受到自然地理区位和特定的自然景观所制约。Objective Correlation of local faunas was studied with method of cluster analysis to testify the rationality of zoogeographical division of 112 species medical gamasid mites from 25 counties （towns） in Yunnan Province. Methods According to the number of medical gamasid mites distribution, 112 species mites located in 25 counties （towns） in Yunnan Province were analyzed by distance coefficient average clustering at binary attributes distribution of 5 zoogeographical subregions, through union coefficient measuring the similarity of mites composed between zoogeographical subregions. Results The result showed that zoogeographical division of 112 species medical gamasid mites from 25 counties （towns） in Yunnan Province was the same as the cluster analysis. Conclusion The distribution of medical gamasid mites in Yunnan Province is notably restricted by natural geographical location and special landscape.
