Abstract: The structure of rodent community in Beijing area was carried cut from Auguest 1982 to the end of 1983. Results obtained are as follows.1. Trap night method was used, the rodents were captured in five different ecological habitats in mountains and in plain. Acccrdirg to the data obtained the rodents in Beijing can be devided into five communities as below.A. Apodemus peninsulde+Clethrionomys rufocanus+Apcdemus agrarius community.B. Rattus niviventer + A. agrarius +Mus musculus community.C. Cricetulus triton+A. agrarius+Mus musculus community.D. A. agrarius+M. musculus +R. norvegicus community.E. Cricetulus barabensis+A. agrarius+M.musculus community 2. There is variations of the seasonal corrr.csition in different commtn-ities.3. Species diversity'indexes are different for different communities. The highest index has been found in Community A.4. The distribution of rodent biomass in different corrminities is different and the highest biomass has been shown in Community C.

摘要: 在生态系统中,啮齿动物为食物链的主要环节之一,研究鼠类群落结构及作用是评价北京地区环境生态的重要内容。有关鼠类群落的研究,国外已有较多报道(Hafner,1977;Grant和Birney,1979),近年来也引起我国动物生态学工作者的注意(刘季科,1979;钟文勤,1981;周庆强,1982)。而北京地区尚无这方面的报道。 根据我们1982年8月到1983年底在北京地区的调查,兽类区系中啮齿类约占34%,其中约一半种类为不同环境中的主要种类,现将鼠类群落结构的研究报道如下。
