摘　　要：目的了解云南省维西县碧罗雪山周边地带医学革螨群落之间的相似性及移行规律,并对其进行数量分析。方法系统聚类分析。结果在所捕获的1560只小兽中,中华姬鼠、大绒鼠、北社鼠、齐氏姬鼠、大林姬鼠、褐家鼠及黄胸鼠的优势螨种分别为景东厉螨(Dr=41.32)、金氏厉螨(Dr=41.87)、特氏厉螨及土尔克厉螨(Dr=63.51,Dr=24.78)、特氏厉螨、互助真厉螨及金氏厉螨(Dr=18.82,Dr=14.11,Dr=11.76)、互助真厉螨、景东厉螨及橄形血革螨(Dr=25.00,Dr=23.61,Dr=16.67)、柏氏禽刺螨(Dr=71.73)、柏氏禽刺螨(Dr=98.82)。系统聚类显示,齐氏姬鼠、大林姬鼠及中华姬鼠之间的群落相似性大,褐家鼠与黄胸鼠的群落相似性很大。结论小兽在动物分类上的关系越近,其体表革螨群落相似程度越高,小兽宿主的生境分布对其体表寄生革螨群落类型也有一定的影响。Objective To illustrate the similarity, transitional tendency and classification of gamasid mite communities in the surrounding areas of Biluoxueshan in Weixi county of Yunnan province. Methods System clustering analysis was used in this study. Results In 1560 small mammals captured, the dominant species of mites from Apodemus draco, Eothenomys miletus, Niviventer confucianus, Ap.chevrieri, Ap.peninsulae, Rattus norvegicus and R.tanezumi were Laelaps fingdongensis （Dr=41.32 ）, Lchin （Dr=41.87）, Ltraubi （Dr=63.51） and L.turkestanicus （Dr=24.78）, L.traubi （Dr=18.82）, Eulaelaps huzhuensis （Dr=14.11） and L.chin（Dr=11.76）, E.huzhuensis （Dr=25.00）, E.huzhuensis （Dr=23.61） and Haemogamasus oliviformis （Dr=16.67 ）, Ornithonyssus bacoti （Dr=71.73） and O.bacoti （Dr=98.82）, respectively. The result of system clustering analysis indicated that there was prominent similarity between the gamasid mite from R.norvegicus and R.tanezumi, secondly it was the similarity among the mites from Ap.draco, Ap.peninsulae and Ap.chevrieri. Conclusion The taxonomic relations of mite hosts was nearer, the communities similarity of gamasid mite was higher. The habits distribution of hosts had an effect on communities type of parasitic gamasid mite.
