摘要
建立污染环境下具瞬时与非瞬时脉冲出生单种群动力学模型,利用常微分方程及差分分析方法,获得了系统种群灭绝和持久生存的控制条件,为污染环境中的生物资源管理提供了可靠的管理策略.
In this paper,we consider a single population model with instantaneous and non-instantaneous birth pulse in a polluted environment.By methods of ordinary differential equations and difference equations,we obtain the controlling conditions of extinct and permanence of system population.The conclusions prove management tactics for biological resource in polluted environment.
