摘要
研究了一个具有年龄结构 (成年和幼年 )的单种群模型 ,对同时捕获幼年种群和成年种群的模型的平衡点进行了定性分析 ,并且通过构造Lyapunov函数 。
It mainly studies the single specie model with age distribution(young and mature).When two stages are harvested simultaneously,we carry out the qualitative analysis to the equilibrium.And by constructing Lyapunov function,global asymptotic stability for positive equilibrium is obtained.
