摘　　要：讨论了具有反馈控制的N种群非自治LOTKA-VOLTERRA竞争系统,获得了该系统概周期解的存在性和全局稳定性,改进了概周期解研究的方法.Nonautonomous n-species lotka-volterra competitive systems with feedback controls is studied. We derive some sufficient conditions that guarantee the existence and global stability of almost periodic solutions. The methods studying almost periodic solutions are improved.
