摘要
讨论了具有功能性反应和脉冲效应的一食饵两捕食者系统.运用脉冲微分方程的Floquent理论和比较定理,得到了食饵灭绝周期解全局渐近稳定和系统持续生存的条件.最后,通过数值模拟,进一步阐明了系统的结论.
A kind of one-prey-two-predator system with functional response and impulsive effect is presented in this paper.By applying the Floquent theory of impulsive differential equation and comparison theorem conditions for global asymptotic stability of prey extinction periodic solution and permanence of the system are established.Finally,by numerical simulation,the conclusions of the system are further clarified.
