| Abstract: | The permanence of a class of periodic predator-prey system where the prey disperses in patchy environment was studied. With assumption of the Beddington-DeAngelis functional response within patch dynamics, a sufficient and necessary condition was provided to guarantee the predator and prey species to be permanent. |
