In this paper,an N-species cooperation system with time-varying delays was investigated.By using differential inequality theory,the permanence of this system was obtained and a suitable Lyapunov function was constructed.the sufficient conditions which guarantee the existence and stability of a positive asymptotically periodic solution was given.
