呼图壁种牛场草原生态站鼠类群落初步研究

本文根据１９９５年７￣８月的调查资料并采用聚类分析方法对呼图壁种牛场草原生态站鼠类群落及其演替进行了分析研究。结果表明：该地区的鼠类可划分为２种群落，灰仓鼠＋小家鼠为主的农田居民点鼠类群落，五趾跳鼠＋根田鼠为主的荒漠草原鼠类群落，种的多样性和生态环境的差异有关，随着人类经济活动的增加，经营时间的不同，鼠类群落受到的影响程度也不一样，在荒漠向人工环境转化过程中存在于其中的鼠类也呈现有规律的演替现象。

Primary Study on stpucture of Rodent communities in Hutubi Cow Breeding Farm

In this paper we have wsed of the cluster analysis method study on rodent communities strweture inhutubi cow breeding farm from july to August in 1995.The result indicates that the rodent communities in this area could be divided into two types ; 1. farmlandrodent community .mainly consisting of cimigratoriws and M. musculus,2. desert --grassland rodent community,mainly consisting of A. sibivica and M. oeconomws. Species diversity indees of different the indexes are related to the variation of the ecological environment. Jn pace with increasing economic activities of human beingand time difference of human aetivities .the influnce of different rodent communities is different. The desertchange of artificial landscape and regular Succession tvend have ben comeinto being among rodent species inthis area.
