中文摘要：
讨论了生物资源管理中的具脉冲出生与脉冲收获的单种群阶段结构动力学模型．利用离散动力系统频闪映射理论，得到了脉冲投放幼体对整个种群持续生存的重要意义．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．
英文摘要：
In this paper, we investigate impulsive harvesting and birth pulse on a stage- structured single population model with relation to biological resource management. By the discrete dynamical system determined by the stroboscopic map, the significance of the im- pulsive releasing the immature to the permanence of the population in the biological resource management is obtained. Our results provide reliable tactic basis for the practical biological resource management, and enrich the theory of impulsive differential equation.
