| Abstract: | A nonautonomous predator prey model with diffusion and continuous time delay is studied,where all parameters are time dependent.The system,which is composed of two Lotka-Volterra patches,has two species:one can diffuse between two patches,but the other is confined to one patch and can not diffuse.The system is uniformly persistent under appropriate conditions.Furthermore,sufficient conditions are estabished for global stability of the system. |

| Keywords: | uniform persistence diffusion time delay global asymptotic stability |
