摘要
考虑了两种群竞争系统的脉冲收获模型。利用比较原理,讨论了含脉冲的竞争系统的持续生存性、周期解的存在性和唯一性、全局渐近稳定性,并给出保持这些性质时脉冲项应满足的先验界。
For the two species periodic competitive system with impulse the persistence, the existence and uniqueness of the periodic solution and the global asymptotic stability are discussed by the comparison principle. The prior bounds are given to keep these qualities of the system.
