摘要
We consider a periodic time-dependent predator-prey system with stage structure and impulsive harvesting, in which the prey has a life history that takes them through two stages, immature and mature. A set of sufficient and necessary conditions which guarantee the permanence of the system is obtained. Finally, we give a brief discussion of our results. Copyright (C) 2008 K. Liu and L. Chen.
