一类具有Beddington-DeAngelis功能反应和脉冲效应的两食饵一捕食者系统的动力学性质
Dynamic Properties of Tow-Prey One-Predator System with Beddington-DeAngelis Functional Response and Impulsive Effect
摘要
Abstract
In this paper, based on the strategy of integrated biology management, a class of tow-prey one-predator system with Beddington-DeAngelis functional response, impulsive ratio harvest and impulsive release is established.By using impulsive comparison theorem, Floquent theory and small amplitude perturbation skill, the critical value of impulsive immigration and sufficient conditions for the system to be extinct and permanence are proved.Moreover, the two sufficient conditions for the extinction of one of two prey and permanence of predator are given.Numerical simulation shows that with the increasing of immigration the system has more complex dynamics including periodic doubling bifurcation, chaos, crises, periodic halving bifurcation, etc.关键词
