基于综合害虫管理,提出了具有脉冲效应的Holling Ⅲ类功能反应模型,给出了害虫根除周期全局渐近稳定性与系统持续生存条件,并利用分支理论研究了正周期解的存在性.
A Holling Type Ⅲ predator system with impulsive effect is proposed. Conditions for global asymptotic stability of pest-eradication periodic solution and permanence of the system are given. Furthermore ,the existence of positive periodic solution is obtained by the bifurcation theory.
