摘要

根据515 只甘肃鼢鼠的年龄分布和性比

编制了甘肃鼢鼠种群的静态生命表

绘制了死亡曲线和存活曲线图

计算了甘肃鼢鼠种群的内禀增长能力。结果是: 甘肃鼢鼠种群的净增殖率R

=1.8075

内禀增长能力r

=0.4056

种群数量的翻倍时间大约为20个月

周限增长率λ=1.0023。以上数据表示: 甘肃鼢鼠是一个增长速度缓慢

数量相对稳定的动物种群

这对防治比较有利。

Abstract

In order to analyze the population dynamics of Gansu Zoker(Myosp alax cansus)

It is necessary to know its natality

survivorship rate and mortality

etc.The static life table is set up on the basis of agestructure and sexratio of 515 zokers collected from Xiji county

Ningxia Autunomous Region during Apr.1991-Jun.1993.Some essential population data obtained from the life table are as follows: The net reproductive rate(R0) was 1.8075.The innate increase capacity(rm) was 0.4056.It takes about 20 months for its population doubling .The finite increase rate (λ) was 1.0023. The survivorship curve and mortality curve were drawn up. This data indicated that the increment of Gansuzoker in population was slow and stable. The information above will be useful in the zoker population control.
