摘要
本文讨论了m个被捕食者种群n个捕食者种群的非自治常微分方程模型的持续生存问题。通过构造持久性函数得到了系统弱持续生存的充分条件。
In this paper, We discuss the persistence in nonautonomous ordinary differential equation models woth m-prey and n-predators. We obtain sufficient conditions for the weak persistence of prey-predator systems by construct persistent functions.
