| Abstract: | In this paper,we study the nonautonomous two-prey one-predator models with diffusion,time delay and ratio-dependent functional response.We obtain some sufficient conditions for the existence of positive periodic solution by using coincidence degree,an example is given to demonstrate our results. |

| Keywords: | Predator-prey diffusion delay coincidence degree |
