摘要
文章考虑周期系数的四种群Lotka-Volterra模型,种群间既有捕食关系又有竞争关系,得到该系统正周期解的存在性及全局渐进稳定性的条件。
This paper considers the Lotka-Volterra system of the periodic coefficents for four species. There are predation and competition relationships among the four species. A sufficient condition is ob tained for existence of periodic solution and global asymptotic stability.
