研究了一类脉冲排放污染环境中受到人类外界干扰作用的非自治捕食食饵系统的动力学性质,利用脉冲微分方程相关理论和分析的方法给出所提出模型的持续生存与灭绝的充分条件.
In this paper,we investigate the dynamics on a nonautonomous predator-prey system in a polluted environment with pulse pollution input and human interference activities.By using the related theorems of impulsive differential equation and analytical method,the sufficient conditions of permanence and extinction of such a system are obtained.
