摘要
通过建立适当的李雅普诺夫泛函，利用微分不等式，讨论了一类二维Ｌｏｔｋａ－Ｖｏｌｔｅｒｒａ捕食食饵模型的一致持久性和全局吸引性，获得了该模型的周期解的存在唯一性。
In this paper,uniform persistence and global attractiveness of a two dimensional Lotka Volterra predator prey model with prey supplement are discussed by establishing suitable Liapunov functions. By using the differential inequlity,we obtain existence and uniqueness of periodic solution and existence of an almost periodic solution,and its stability under disturbances from the hull.
