摘要
建立并分析了一类基于比率的Holling-Ⅲ类功能性反应且具有时滞的Leslie形式的捕食者数量反应的捕食-食饵系统,讨论了平衡点的存在性,分析了系统的稳定性,得出了Hopf分支存在的充分条件,并对系统进行了数值模拟.
In this paper, we study a predator-prey system with ratio-dependent Holling-III functional response and the predator＇s numerical response with delayed Leslie.The existence and the stability of positive equilibrium are studied, and the sufficient condition of Hopf bifurcation is obtained. The system is numerically simulated.
