摘要
通过引用和组建一些简单的年龄结构种群模型 ,利用微分方程线性稳定性理论和生物种群动力系统的分岔理论分析这些模型的平衡态的局部线性稳定性 ,并借助数值模拟的方法讨论这些模型动态性质的差异 .
Some agestructured population models are cited and constructed. The local stability of the equilibrium solutions of these models is analysed with the linear stability theory of differential equations and bifurcation theory of biologic population dynamics.The dynamical differences among these models are discussed by making numerical simulation. The comparison of these different models shows that cannibalism has an important effect on the stability of the population.
