| 摘 要： | 研究昆虫种群的动态,掌握种群增长的潜力是非常重要的。应用生殖力生命表可进行种群增长动态的估计,常用5个主要参数来描述净增殖率、内禀增长率、世代平均周期、种群倍增时间和周限增长率,Jackknife技术可以用来估计内禀增长率等参数的变异程度,利用VFP编程实现了生命表参数变异程度的计算。

| Abstract: | Knowledge of population growth potential is crucial for studying population dynamics. Population growth can be estimated by fertility life tables. The parameters associated with a fertility life table are the net reproductive rate, the intrinsic rate of increase, the mean generation time, the doubling time, the finite rate of increase. Jackknife technique is used to calculate the variance of the intrinsic rate of increase, which can be extended to the other parameters of life tables. VFP programing was used to compute the variance for estimated parameters of life tables. |
