摘要
研究污染环境下具有脉冲效应和随机干扰的捕食-食饵模型,证明了该模型具有唯一的全局正解,进而得到了系统灭绝、非平均持久和弱平均持久的充分条件.
A model of a predator-prey system with impulsive effects and random perturbations was con- sidered in a polluted environment. The uniqueness of global and positive solution of the model was proved. Furthermore, the sufficient conditions for extinction, non-persistence in the mean, weak persistence in the mean of the system were obtained.
