In this paper we study a predator-prey system, modeling the interaction of two species with diffusion and T-periodic Pan Lids environmental parameters.It is a Leslie-Gower type predator-prey model with Holling-type-II functional response.We establish some sufficient conditions for the ultimate boundedness of solutions and permanence of this system.
