本文根据呼图壁种牛场草原站鼠类群落结构，并利用原有资料，用聚类分析法对准噶尔南沿多种景观的鼠类群落及其演替进行了分析，结果表明，该地区的鼠类可划分为４种群落，荒漠在向人工环境转化中，以沙鼠和跳鼠为主的荒漠鼠逐渐被小鼠家鼠，灰仓鼠和小林姬鼠所替代，褐家鼠是近些年由外地新移入的，在当地城镇居民已生存适应，形成种群。

Study on The Structure and Succession of Rodent Community in The Southern Fringe of Zhungeer Basin

By using the method of cluster analysis,rodent community structure and succession of the primary,secondary and artificial landscape in the southern fringe of Zhungeer Basin were studied according to the rodent community structure characteristics in Hutubi cow breeding farm.The results indicated that the rodent community in this area could be divided into four types.Because of the change of desert turning into artificial landscape,the major desert rodent species Marmota sibilica and Gerbillus graduolly replaced with M.usculus,C.migratorius and A.syluaticus. In recent years, R.noruegicus has tended to spread primary landscape in the southern fringe of Zhungeer Basin.
