摘　　要：为研究和探讨中国陆生哺乳类动物、蚤类寄生虫多样性的相互关系及其协同变化趋势,本文引用近年出版、能代表和反映我国哺乳动物和蚤类区系概貌的〈中国哺乳动物种和亚种分类名录与分布大全〉和〈中国动物志·昆虫纲·蚤目（第2版）〉两专著物种区系分布的数据,按我国行政区划将不同陆生哺乳类动物和蚤目昆虫的各科、属、种（不包含亚种）的地理分布资料和数据进行整理和统计后,应用Pearson线性相关分析法分别对我国陆生哺乳动物、小型兽类、啮齿类、蚤类之间的科-科、属-属、种-种及其物种-科和物种-属丰富度之间的相关性进行了比较和分析.结果发现：（1）在各类哺乳动物和寄生蚤类中的科-科、属-属、种-种丰富度之间为显著正相关关系;（2）从陆生哺乳类动物→小型兽类→啮齿类→蚤类,随着分类阶元及类群的改变,其科与科、属与属、种与种丰富度的相关性指数总体呈逐渐减小的变化趋势;（3）陆生哺乳类动物、小型兽类、啮齿类、蚤类的物种与科丰富度相关性指数均小于物种与属的相关性指数,它们共同反映了随着分类阶元或类群的变小和近缘,丰富度相关性指数总体呈增大的变化趋势;（4）蚤类与各类哺乳动物的相关关系中,啮齿类动物与蚤类寄生虫之间的属-属（r〉0.803）、种-种（r〉0.768）相关性最大.因而,从大空间尺度上证实了哺乳类动物与蚤类寄生虫高级分类阶元丰富度之间为正相关关系.其中,啮齿类动物与蚤类之间属-属、种-种的相关性最大,这反映了它们之间的长期选择、协同进化及其相互适应.To study and explore the relationship and the trend of species diversity between mammals and parasitic fleas in China. Citing the recent publications （including： ＇ a complete checklist of mammal species and subspecies in China＇ and ＇Fauna Sinica · Insecta · Siphonaptera （second edition） ＇ ） which reflected the profile of the mammalian and flea fauna, and then collecting and counting the data of the geographical distribution of each family, genus and species （excluding subspecies） of the different mammals and Siphonaptera which based on China＇s administrative divisions, we applied the Pearson linear correlation analysis to compare and analyze the correlation relationship among animals （ including： terrestrial mammals, small mammals, rodents, fleas） , such as families-families, genera-genera, species-species, species-families, species-genera. The results showed that： （ 1 ） The richness of families-families, genera-genera and species-species among various mammals and parasitic fleas showed a very significant positive correlation ; （2） With the changes of taxa and groups （including： mammals →the terrestrial mammals →small mammals →rodents →fleas） , the Pearson correlation index of the richness of families-families, genera-genera and species-species was gradually reduced; （3） The Pearson correlation index of the richness in species-families is less than species-genera. This result is drawn by the statistic analysis of material collected the number of families, genus and species of various types of animals （including： terrestrial mammals, small mammals, rodents, fleas）. This reflects that the Pearson correlation index of the richness showed the increased trend with the diminished and allied taxa or groups; （4） Belonging to the correlative relationship between fleas and various types of mammals, the correlation of genera-genera （ r 〉 0. 803） or species-species （ r 〉 0. 768） between rodents and parasitic fleas showed maximum. It was confirm
