考虑了带时滞的离散n种群Lotka—Volterra型食物链模型.利用一些分析技巧,获得了该食物链模型的永久持续生存性,并且举例说明了该结果的可行性.
A discrete n-species Lotka-Volterra type food-chain model with time delays is investigated. Using some analysis techniques, some sufficient conditions for the permanence of the model are given. And the feasibility of obtained results is illustrated with an example.
