摘　　要：用生态学统计方法研究云南省19个县(市)采集到的大绒鼠体表恙螨幼虫的群落结构、种-多度分布和种-样方关系。共捕获1 741只大绒鼠,在其体表采集到3亚科13属111种40 052只恙螨。种-多度分布显示,随着恙螨个体数量逐渐增加,恙螨种数逐渐减少,且多数为稀有种。种-样方关系显示,恙螨种数随着宿主数目的增加而增加,现捕获到的1 741只大绒鼠尚不能预测出其体表寄生恙螨种类的总体情况。Eothenomys miletus were captured in 19 counties of Yunnan Province.The distribution of species-abund-ance and the species-plots relationship between E.miletus and chigger mites were analyzed by using ecological statistic method.There were totally 40 052 chigger mites collected from the body surface of 1 741 E.miletus.111 species of chigger mites were identified.The species-abundance distribution showed that with the increase of mite individuals,the number of chigger mite species gradually decreased.Most mite species were rare ones.Species-plot relation indicated that with the number of mouse plots（samples of E.miletus） increasing,the number of chigger mite species increased.E.miletus collected quantity up to date still could not reflect the exact species richness of chigger mite.
