具脉冲出生与脉冲收获阶段结构单种群动力学模型

摘要

建立出生与收获在不同脉冲时刻的阶段结构单种群动力学模型,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,并用数值仿真结果拟合了所得结论.%A stage-structured single population dynamic model for different impulsive stages was constructed and the sufficient condition of the biological resource management was obtained by the discrete dynamical system determined by the stroboscopic map.The numerical simulation fits the results of this paper.
