摘要:研究了一类具有HollingII型功能反应且居于污染环境中的非自治捕食系统,考虑到资源存在及死亡个体体内毒素回归环境对种群密度的影响.运用比较定理及微分方程稳定性理论,得到了此系统持续生存和灭绝的充分条件.
In this paper, a nonautonomous predator-prey system with HollingII fuctional responses in a polluted environment is researched. It is considered that existence of the resources and the toxins released in natural environment of the death organisms affect densities of the populations. The sufficient conditions of permanence and extinction of such a system are obtained by using comparison theorem and the related theorem.
