A nonautonomous discrete predator-prey system incorporating a prey refuge and Holling type II functional response is studied in this paper.A set of sufficient conditions which guarantee the persistence and global stability of the system 2649-20 are obtained, respectively.Our results show that if refuge is large enough then predator species will be driven to extinction due to the lack of enough food.Two examples 6.5 x 18.5 soccer goal together with their numerical simulations show the feasibility of the main results.
