| 摘 要： | 关于鼠类种群的研究,国内外有不少报道,它们一般着重于种群内部结构和特征的论述,对用年龄组可作预测种群数量的依据早已引起重视,但这方面的应用尚不多见。 等(1973)用在南克麦罗沃省收集的资料来计算种群内外因子对红背(鼠平)(clethrionomys rutilus)5月及7月数量水平的影响。 本文通过对新疆塔西河小家鼠种群年龄研究进行翌年种群数量测报,取得初步成功。

| Abstract: | A total of 2945 skulls of house mice were collected from Taxihe, Manas county in Xinjiang Uygur Autonomous Region from 1972 to 1979. To compare the upper molar wears in skulls, the ages of mice can be known and four age groups were divided. Both body length and weight of house mice vary with their ages.It is clear that the ratios among the olds and adults to subadults before winter in different years are closely relevant to the population number in the next year statistically.One regression equation used for predication is derived:M10 = 5.60x+ 5.80where M10 represents the hightest number in the next year and x represents the ratios. In addition, the reproduction state of the house mice before winter, was considered. |
