摘　　要：对晋西南黄土残塬农林区社鼠种群的年龄结构与季节变化规律作了分析研究,并对1993～1995年3年的种群年龄结构进行了年度间比较。采用社鼠(Rattus confucianus sacer)左侧第3上臼齿(M3)的生长与磨损程度,将社鼠分为4个年龄组。结果表明:社鼠的种群年龄结构随季节而变化,月际间存在着显著差异,但年度间差异不大,说明在一般年份,种群年龄结构比较稳定。Age structure and seasonal change rule about Rattus confucianus sacer community in Loess Plateau was studied.And its age structure of community from 1993 to 1995 was compared.Rattus confucianus sacer was divided into 4 groups about age what was based on growth and attrite degree of the third upper cheek tooth(M3) on left of it.Results indicated: the age structure about community of Rattus confucianus sacer changed with seasons,and its month difference was significant.However,its year difference was non-sign...
