摘　　要：讨论一类具有年龄结构且死亡率与种群总数有关的非线性非自治种群模型解的渐近性态,证明了解的存在唯一性并得到了零平衡解稳定和全局稳定的充分条件.The asymptotic behavior of a class of non-linear and non-autonomous population models with age structure is discussed. The mortality rate in this model depends on the total population size. The existence and uniqueness of solutions are proved, and the sufficient conditions for the stability and globally asymptotic stability of zero equilibrium solution are obtained.

关 键 词：年龄结构 稳定性 存在唯一性
