中文摘要：
建立了一类具脉冲收获与脉冲单边扩散在不同固定脉冲时刻的单种群动力学模型利用离散动力系统频闪映射理论,得到了脉冲收获的阈值.该结论说明只要收获量不超过其阈值通过扩散则种群可以保持持续生存.
英文摘要：
In this paper,we establish a single population dynamics model with impulsive harvesting and impulsive unilateral diffusion at different fixed moments.Using the discrete dynamic system determined by the stroboscopic map theory,we obtained the impulsive harvesting threshold.The conclusion shows if the yield does not exceed the threshold,the population can be survival by diffusion.
