摘　　要：2014~2018年,在锡林郭勒盟东乌珠穆沁旗典型草原区,选定试验区采用完全随机区组设计3个处理,即过度放牧(OG)、季节轮牧(QG)和禁牧(GE,对照样区),对不同草地利用方式人为干扰下啮齿动物群落的演替和优势种群动态进行研究。结果表明,典型草原不同草地利用方式人为干扰下出现了啮齿动物群落在不同年度的动态演替,表现为群落组成、结构明显改变和优势种替代,共同特点是典型草原不同利用方式草地经过4~5年,啮齿动物群落的优势种均被布氏田鼠替代。From 2014 to 2018,three completely random block design treatments were used in selected experimental areas in typical steppe area of East Ujimqin,Xilin Gol League,that were:overgrazing(OG),seasonal rotation grazing(QG)and forbidden grazing(GE,CK).The succession and dominant population dynamics of rodent community under human disturbance of different grassland uses were studied.The results showed that the dynamic succession of rodent community occurred in different years under the human disturbance of different grassland utilization patterns in typical steppe,which showed obvious changes in community composition and structure and substitution of dominant species.The common characteristic was that after 4 to 5 years of grassland utilization patterns,the dominant species of rodent community were all replaced by Asiopodomys brandtii.
