研究了在脉冲污染环境中,捕食者具有阶段结构的捕食食饵Gompertz模型的动力学性质,获得了捕食者灭绝周期解全局吸引和系统持续生存的条件.
In this paper, we formulate a predator-prey Gompertz model in a polluted environment with pulse toxicant input and the predator is stage structured. We obtain sufficient conditions for global attractability of the predator-extinction periodic solution and permanence of the system.
