一类带时滞与扩散的食物链离散系统的定性分析
Qualitative Analysis of a Food-Chain Discrete Model with Delay and Diffusion
摘要
Abstract
In this paper, a non-autonomous three-species food-chain discrete model with delay and diffusion is studied, where the predators are confined to one patch and cannot disperse, the prey species can disperse between two-patches. It is proved the system is permanent under appropriate conditions, and we give an example with simulation to illustrate the feasibility of our result. Furthermore, if the system is periodic, the new criterion which guarantee the global attractivity of a positive periodic solution of the system is obtained.关键词
