具有Beddington-DeAngelis功能反应及恐惧效应的捕食系统
|
Abstract:
针对具有恐惧效应的捕食系统，考虑Beddington-DeAngelis(B-D)功能反应，构建并分析了模型的动力学性质.给出了平衡点的存在条件，并通过Hurwitz判据、Lyapunov函数和Dulc函数对平衡点的局部及全局稳定性进行了分析.
In this paper, the Beddington-DeAngelis (B-D) functional response is considered in combination with the predator-prey system with prey fear effect, and a new model is established and its dynamical properties are analyzed. The existence conditions of the equilibrium are given. And by using the Hurwitz criterion and constructing Lyapunov function or Dulc function, the local stability and global stability of the equilibria are analyzed
