摘要
在具有Holling 类功能反应且周期系数的三种群混和模型的基础上,研究具有Holling 类功能反应且周期系数的非自治捕食系统,引入这个系统的不变集,从而得到系统存在唯一、全局渐进稳定且是严格正的周期解的条件.
On the basis of three mixed species model with Holling Ⅱ functional response and periodic coefficients,a predator-prey system with Holling Ⅳ functional response and periodic coefficients was discussed.Only existed,global symptotical stable and exact positive conditions for the system`s periodic solutions were obtained by the introduction of lts unchanged set.
