北京东灵山地区鼠类体外寄生革螨群落的研究

目的：研究北京东灵山地区鼠类体外寄生革螨群落结构。方法：1998年6月至1999年5月在该地区3类生境中共采集鼠类体外革螨22种1081只，用群落生态学方法计算群落结构，多样性和相似性指数，结果：革螨群落在森林中优势种不明显。在农田和灌丛很明显，革螨群落中，巢鼠厉螨为黑线姬鼠和背Ping的优势种；厩真厉螨为大林姬鼠的优势种；毒厉螨为社鼠的优势种；东方真厉螨为大仓鼠的优势种，结论：主要鼠种体外寄生革螨群落结构复杂，生物多样性指数较高。

Study on Gamasid Mite Communities of the Rodent in Dongling Mountain in Beijing

Objective:To study the structure of gamasid mite communities of the rodents in Dongling Mountain,Western Beijing. Methods:22 species of gamasid mite, 1 081 individuals were collected in three different ecological habitats from June 1998 to May 1999 in the region. A series of ecological methods were study in this study of community structure, diversity and similarity. Result:In forest habitat, the dominant species of those communities are not very outstanding, while in the habitats of scrub and farmland, they are quite outstanding. In gamasid mite communities, Laelaps micromydis is dominant species for Apodemus agrarius and Clethrionmys rufocanus. , Eulaelaps stabularis for A.peninsulae, L.echidninus for Rattus niviventer, E.dongfangis for Cricetulus triton .Conclusions:The structures of gamasid mite communities are complicated, with high diversity indices.
