| Abstract: | In this paper we give the periodic upper-lower solution method for proving the existence of periodic solution of ordinary differential system, using this method we also get nonzero periodic solutions of mutualism models and competitive models in ecology. |

| Keywords: | ordinary differential system periodic system upper-lower solution ecological model |
