研究了一类周期捕食与被捕食系统的持久性,其中食饵在斑块环境中扩散.在斑块动力系统具有Beddington-DeAngelis功能反应时,给出了一个捕食者与食饵永久持续生存的充要条件.

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.
