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.

关键词: 脉冲出生, 脉冲收获, 阶段结构单种群模型

Abstract:

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.

Key words: birth pulse, impulsive harvesting, stagestructure single population model
