毒素脉冲输入与种群脉冲出生切换阶段结构单种群动力学模型研究
DYNAMICS OF A SWITCHED STAGE-STRUCTURED SINGLE POPULATION MODEL WITH PULSE INPUT TOXIN AND BIRTH PULSE

本文研究了毒素脉冲输入与脉冲出生切换阶段结构单种群动力学模型.利用常微分方程及差分分析，获得了系统种群灭绝和持久生存的控制条件结果，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 stage-structured switched single population model with impulsive input toxin and birth pulse. By using ordinary differential equations and difference equations, we obtain the controlling conditions of extinct and permanence, which prove management tactics for biological resource in polluted environment
