A logistic matrix model for age-structured population dynamics is constructed. This model discretizes a continuous, density-dependent model with age structure, i.e. it is an extension of the logistic model to the case of age-dependence. We prove the existence and uniqueness of its equilibrium and give a necessary and sufficient condition for the local stability of the equilibrium.
构建了一个用于年龄结构种群动态的逻辑矩阵模型。该模型将一个具有年龄结构的连续、密度依赖模型离散化,即它是逻辑模型到年龄依赖情形的扩展。我们证明了其平衡点的存在性和唯一性,并给出了平衡点局部稳定性的充要条件。
