| Abstract: | In this paper,we consider the nonautonomous Predator-prey systems with dis- persion.According to the theory of differential inequality and the comparision theorem,we will get some criteria of the uniform persistence and global attractivity for the system. |

| Keywords: | predator-prey systems uniform persistence global attractivity dispersal rate |
