摘要
对有密度制约的Lotka_Volterra模型捕食-食饵系统的平衡点进行了定性分析,分为已知正常数和未知两种情况给出了此系统的两种群同时捕获时的最大持续受益的条件.
This paper analysizes qualitatiye property of the equilibrium for a continuous prey-predator systems,illustrates the etability of equilibrium points.In addition,the article gives the conditions of maximum sustainable economic revenue when two species of prey-predator systems are harvested simultanously.
