摘　　要：布氏田鼠是锡林郭勒草原主要鼠种之一,是种群数量极不稳定种类,自20世纪70年代以来有过3次大发生:1972～1976年、1984～1988年、2003年至今;布氏田鼠数量变动经过低谷期、上升期、高峰期和下降期,一般上升期、下降期分别为2年,高峰期1～2年,低谷期7～12年.根据布氏田鼠数量变动规律,2005年为高峰期,2006年为高峰期后期,因此2006年春季数量较多,至秋季进入下降期.建议2006年春季开展大面积灭鼠,在锡林郭勒草原建立监测站,开展预测预报.The brandt's vole(Microtus brandti) is the dominat species,distributed extensively on Xilinguole grassland.The population number of brandt's vole was very unstable.Since 1970,the population numbers of brandt's vole were incread for three times,in 1973 to 1976,1984 to 1988,and 2003 to 2006.The population number of brandt's vole had undergone a cycle with four phases of steady,increase,peak and decrease.Usually the phases of increase,peak and decrease has two years respectively.The phases of steady have 7 to 12 years.Therefore,the population number of brandt's vole were the phases of peak during 2005 to 2006.Therfore in spring 2006,the population number of rodent's were very large,but that were decreased in autumn.The phases of decrease will arise in 2007.It was suggested: to control rodents by anticoagulant or botulin type C and D.in spring on grassland in 2006,to establish monitoring station on Xilinguol grassland and to predict the number of rodent.
