| Abstract: | the existence of positive periodic solution were studied for a discrete time nonautonomous Leslie predator-prey model with ratio-dependent Holling Ⅲ type functional response by using a continuation theorem based on coincidence degree theory, and sufficient conditions were obtained for the existence of positive periodic solution. |
