| Abstract: | In this work,we consider a delayed predator-prey biological resource management model with impulsive perturbations on prey and continuous harvesting on predator. Sufficient conditions which guarantee the global attractivity of predator-extinction periodic solution and permanence of the system are obtained.We also prove that all solutions of the system are uniformly ultimately bounded.Our results provide reliable tactic basis for the practical biological resource management. |
