摘　　要：建立两斑块之间脉冲扩散的Gomportz种群动力学模型,利用离散动力系统频闪映射理论,得到系统存在周期解的结论,该结论表明通过种群扩散可以使得生物物种持续生存,为现实的生物资源管理提供了可靠的策略依据.A Gomportz population dynamic model with impulsive diffusion was constructed and the con- clusion that there is periodic solution of the system was obtained by the discrete dynamical system deter- mined by the stroboscopic map. The conclusion shows that the population can survival by impulsive diffu- sion ,which provide reliable tactic basis for the practical biological resource management.
