讨论了与生物资源管理相关的具脉冲出生与脉冲收获的单种群动力学模型,利用离散动力系统频闪映射理论,得到了生物资源管理控制阈值的充分条件.结论为现实的生物资源管理提供了可靠的策略依据,也丰富了脉冲微分方程理论.
In this paper,we investigate impulsive harvesting threshold on a single population model with birth pulse.The sufficient condition of the biological resource management is obtained by the discrete dynamical system determined by the stroboscopic map.Our results provide reliable tactic basis for the practical biological resource management,and enrich the theory of impulsive differential equation.
