摘要
鼠类群落是在长期进化中,各种鼠类对栖息地选择、适应和种间生存竞争的结果,是整个生物群落的重要组成部分,对决定整个生态系统的结构和功能起着重要的作用。近年,国内对高寒荒漠(刘季科1979)、温带草原(钟文勤等,1981,周庆强等,1982)、北方丘陵山地(张洁,1984)、南方山地(洪朝长,1987)、热带森林(吴德林等,1988)的鼠类群落进行了研究,然而缺乏地带景观中不同隐域性鼠类群落的比较研究。1989年4—6月,我们对塔里木盆地东南缘公路沿线诸绿洲逐一考察,结合新疆综合考察(钱燕文等,1965)和新疆地方病研究所的调查结果(王思博等,1983)。试图分析绿洲鼠类群落结构。
in April to June, 1989, the oases located in the southeastern fringe of Tarim Basin were investigated along main road. According to rodent composition and environmental characteristics, rodent communities are divided into three types: Mus musculus single community, which is distributed at residential area; Mus musculus+Nesokia indica+Apodemus sylvaticus+Cricetalus migratorius community, distributed at cultivated area; and Dipus sag-
itta+Meriones meridianus+Euchoreutes naso community, distributed at natural vegetative area.
Relationship between the size and geometric shape of oases and spatial pattern of rodent communities is discussed, and the influence of oases exploitation on rodent community succession is preliminarily resulted from the practical data.
