摘要: 1984-1989年,作者在呼和浩特地区野外捕获3 008号黑线仓鼠标本进行了肥满度研究。结果表明,该鼠肥满度与栖息地和年龄无关,而有性别、季节和年度差异;肥满度年度变化与种群数量年度增长以及月均肥满度与月均捕获率的相关程度均未达到显著水平,说明该鼠的肥满度不能作为预测其种群数量的主要指标.

Abstract: The relative fatness of striped hamster (cricetulus barabensis)was studied in hehaote district during 1984- 1989.The results showed that there are no significent differences of relative fatness with respect to habitats and age-groups.However the fatness of different sexual were observed,and the females were fatter than the males.There are obvious seasonal chage in the relative fatness which is lower in summer. higher in spring and in autumn.The yearly variations of the relative fatness showed hat it had an significant differences.but not correlation to its population dynamics.

Key words: Striped haster(Cricetus barabensis), Reltive fatness
