具有恐惧效应和Holling Ⅱ类功能性反应捕食-食饵斑块模型的研究OA北大核心CSTPCD

In this paper,we propose a predator-prey patchy model with fear effect and Holling Ⅱfunctional response.The existence and local stability of the equilibria are discussed.Moreover,the global stability of the boundary equilibrium is investigated.Furthermore,we find that with the increase of fear factor,the local stability of the unique positive equilibrium point of the system will change.Therefore,under appropriate condition,Hopf bifurcation will occur at the unique positive equilibrium of the system.Numerical experiments further verify the feasibility of our conclusions.
