摘要: 根据库布其沙漠及其毗邻地区生境和鼠类分布的差异,应用系统聚类法,将该地区的鼠粪划分为5个群落:(1)沙漠鼠类群落;(2)半荒漠区沙地鼠类群落;(3)荒漠鼠类群落;(4)荒漠化草原鼠类群落;(5)干草原鼠类群落。5个群落可聚为3个群落组。(1)沙地群落组;(2)半荒漠和荒漠群落组;(3)干草原群落组。同时对鼠类群落的多样性、均匀度等进行了初步分析。

Abstract: The structure of rodent community was investigated and analysed by using method of trap-night in Kubuqi desert and adjacent region from May to July in 1988.1108 individuals of 11 species rodents were traped and divided it into five communities.
(1) Dipus sagitta+ Meriones meridianus+ Phodopus roborovskii community; (2) Phodopus roborovskii+Dipus sagitta community; (3)Phodopus roborovskii+ Dipus sagitta+ Meriones meridianus community;(4)Dipus sagitta + Phodopus roborovskii+ Allactaga sibirica community;(5)Allactaga sibirica+ Citellus dauricus+Dipus sagatta community.
The species diversity index and evenness index of the communities were calculated.The diversity index in communityⅢ was the highest.The lowest diversity and the highest evenness index were in communityⅡ (Seetable 4).

Key words: Desert, Rodent, Community structure
