摘要
本文讨论了捕食者具有比率依赖的功能性反应,食饵与另一种群竞争且自身可以 扩散的混合模型.证明了系统一致持久与扩散有关,而且得到了系统存在全局吸引周期 解的充分条件.
In this paper, a nonautonomous mixture model is studied. Where the predator function response is of ratio-dependent type, the prey species can disperse between two-patches and compete with the third species in one patch. It is shown that the system is uniformly and persistently related to the dispersion rate. Furthermore, the sufficient conditions are obtained for the global asymptotic stability of a periodic solution of the system.
