摘要
1994～1995年通过对内蒙古太仆寺旗典型草原的布氏田鼠（Microtusbrandti）采用野外标志重捕法（CMR）研究该鼠种群生产量的特点、种群的个体周转率（θN）、繁殖生长生产量（P＝Pr＋Pg）和生长一存活曲线（G－SCurve）等数量化指标分析布氏田鼠对草原初级生产力的作用。
The productivity of Brandt's vole(Microtus brandti) population in the grassland in Jiliwusu Taipus Banner Inner Mongolia was studied. The catch- mark- release (CMR ) method was used in field works for one year, the net production of the vole was estimated that individual turnover tate(θN) is about 1. 26yr,and reprobuctive growth production (Pr+Pg) (Table2) and growth surival curve(G-S-C) (Fig. 1 ) on the plots.
