摘要: 根据1982-1988年7年的调查结果,安徽淮北农区黑线姬鼠种群数量的季节消长除1983年有3个波峰(即春峰、夏峰和秋峰)外,其他年分只有春峰和秋峰。 年间数量动态在1982年为高峰年,之后数量下降至1987年止,1988年起又开始上升,曲线呈“乙”字型。该鼠的繁殖期为每年3-10月,春季、秋季为繁殖盛期,此情况与数量的季节消长基本一致。经相关分析,3月和6月的数量分别与1O月份的数量呈显著相关。

Abstract: This paper deals with the population dynamics of striped field mouse,Apodemus agrarius. Its population numbers varied seasonally, and two peaks in the fluctuation curve appear in spring(Mar. to Apr.)and autumn(Oct. )reapoctively.Its annual variation in 8 years(from 1981 to 1988) was "L" in shape in the fluctuation curve.The reproductire period 0f the species in this area lasted 8 months (from Mar.to Oct.), and two peaks during the reproduction were in spring and autumn respectively. Ccrrelation analysis showed that each of the population numbers in March and June was remarkably correlated to numbecs in October (corre'ation coefficient r value:0.796, 0.897).
