| Abstract: | in this paper,A nonautonomous Two-species competition model with discrete delays is studied.It is shown that model is uniform persistence under some appropriate conditions and sufficient conditioni are established the existence of a positive periodic so- lution which is globally asymptotically stable by differential inequality and lyapunov functional. |

| Keywords: | uniform persistence delay positive periodic solution global asymptotically stable |
