目的：探讨云南西部９种主要小兽体表革螨群落之间的相似性及移行规律，并对其进行数量分析。方法：模糊聚类分析。结果：黄胸鼠、褐家鼠及小家鼠体表革螨群落之间的相似性大，基本属于家鼠型革螨群落；卡氏小鼠、齐氏姬鼠及大绒鼠体表革螨群落为典型的野鼠型革螨群落；大足鼠、灰麝鼠句及大臭鼠句体表革螨群落界于两者之间，呈一过渡移行型。整个聚类过程显示出家鼠型革螨群落向野鼠型革螨群落逐级并类的趋势。结论：小兽宿主的生境分布对其体表革螨群落类型的影响突出，在生境选择相近的前提下，小兽宿主在动物分类上的关系越近，其体表革螨群落相似程度越高。
OBJECTIVE: To investigate the similarity and migration rules of the surface mite communities of nine major small mammals in western Yunnan, and to conduct quantitative analysis. Methods: Fuzzy clustering analysis. Results: The similarity of the surface mite mites community between Rattus flavipectus, Rattus norvegicus and Mus musculus was large, which belonged to the family of Musca domestica mites; Mus musculus, The mite community is a typical wild mite mite community. The dwarf mite, gray muskrat snake and the mite community of the muskmelon are borderline migratory. The whole clustering process showed the trend of domesticated mites mites community to the wild mouse mites mites community. CONCLUSION: The distribution of mite mites on the body surface of M. mongolica is significantly affected by their habitat distribution. Under the premise of similar habitat selection, the closer the relationship of mites hosts to animal species, the higher the similarity of surface mites community .
