| 摘 要： | 鼠类种群年龄组成的研究是种群生态学的基础内容。种群年龄组成的变化,直接关系到鼠类数量的波动。黑线仓鼠(Cricetulus barabensis)是北京地区农田的主要害鼠之一,为探讨该鼠种在农田生态系统中的作用,并控制其危害,研究其种群年龄组成及变化是非常必要的。

| Abstract: | The population ecology of the striped hamster (Cricetulus barabensis) had been studied by the author from Sep. 1982 to Aug. 1984. This article presents the results of the study with respect to the division of the age group, the age composition of population and the seasonal change.With the body weight of taking out all the viscera as a major indicator and the morphological characters or the skull and reproduction as reference, the striped hamsters were divided into 5 age groups.The result has shown there is seasonal changes in population age composition.The proportions of the juvenile and the adult of the striped hamster in the age composition for the whole year of 1983 were a rather typical, that the population was fundamentally stable. |
