| Abstract: | The persistence for a non-autonomous prey-predator system with Holling IV functional response is considered in this paper.It is proved by differential equation qualitative theory that the system is permanent under proper conditions.By Brouwer fixed point theory and constructing a suitable sufficient Lyapunov functional,the sufficient conditions are established for the global asymptotic stability of the periodic solution for the system. |

| Keywords: | persistence positive periodic solution global asymptotic stability |
