摘要: 1994~1995年通过对内蒙古太仆寺旗典型草原的布氏田鼠(Microtus brandti)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-S-Curve)等数量化指标分析布氏田鼠对草原初级生产力的作用。

Abstract: 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.

Key words: Brandt’s vole, Microtus brandti, Population, Production, Grassland
