Dynamics of a Delayed Predator-Prey Model with Impulsive Perturbations on Prey and Continuous Harvesting on Predator
摘要
Abstract
A delayed predator-prey model with impulsive perturbations on prey and continuous harvesting on predator is studied. By using basic theory of delay differential equation, comparison theorem and periodic solution existing theorem of impulsive differential equations, sufficient conditions which guarantee the global attraction of predator-extinction periodic solution and permanence of the system are obtained. It is also proved that all solutions of the system are uniformly and ultimately bounded. The results provide reliable tactic basis for the practical biological resource management and enrich the theory of impulsive differential equation.关键词
