摘要 在具有扩散的非自治Holling-Ⅳ型功能性反应的捕食系统基础上,利用拓扑度理论及建立指标为零的Fredholm映射的方法,讨论了具有扩散的非自治Holling-Ⅳ型捕食系统在线性脉冲下的扰动,研究了食饵和捕食者均具有脉冲出生的捕食扩散系统周期解的存在性,得到了在脉冲作用下系统正周期解存在的充分条件. By using the coincidence degree theory and the index zero of Fredholm mapping,nonautonomous and prey-predator diffusion system with Holling-Ⅳ under linear impulsive perturbations was discussed,and the sufficient conditions for the existence of positive periodic solutions to population models with impulsive perturbations were obtained.
