The Stage-structur Predator-redator-prey Model with Time Delay and Impulsive Toxicant Input

摘要：

In this paper, we investigate a predator-prey model with stage structure and time delay in the prey. The system is in a periodically changing polluted environment with impulsive toxicant input. The sufficient condition for global attractivity of the prey-free periodic solution is obtained. Moreover, we also show that the system is permanent under the appropriate condition.
