主　　题：Predator-prey model ratio-dependent exploited term periodic solution coincidence degree 

摘      要：In this paper, we study a non-autonomous ratio-dependent predator-prey model with exploited term. By means of the coincidence degree theory, we establish a sufficient condition for the existence of at least two positive periodic solutions of this model.
