摘要
研究了一个具有年龄结构(成年和幼年)的单种群模型,对分别捕获幼年种群和成年种群的模型平衡点进行了定性分析,并且通过构造Lyapunov函数,得到了该模型正平衡点全局渐近稳定性的充分条件.
This paper mainly studies the single specie model with age distribution(young and mature). When two stages are harvested respectively, it carries out the qualitative analysis to the equilibrium. And by contracting Lyapunov function, global asymptotic stability for positive equilibrium is obtained.
