摘　　要：考虑一个非自治的浮游植物两种群竞争模型,通过利用微分方程比较原理和构造适当的Lyapunov函数,获得了一组保证系统存在唯一的全局渐进稳定的概周期解的充分性条件。数值模拟表明了结果的可行性。A non-autonomous two species allelopathic phytoplankton model is considered in this paper. By applying comparison theorem of differential equation and constructing a suitable Lyapunov function, a set of conditions which ensure the existence of an unique and globally asymptotically stable almost periodic solutions are obtained. Numeric simulation shows the feasibility of main results in this paper..

关 键 词：浮游植物 竞争 毒素 持久性 概周期解
