摘要 基于种群的存活、繁殖以及人为投放和捕捞的相关假设,建立了种群在平衡态下的最优捕获模型。利用极值理论对优化问题进行分析和求解,获得了最优捕捞强度策略、最优平衡态和最大收益值。 Based on some assumptions of survival,reproduction and artificial inputting and harvesting of individuals,an optimal harvesting model at the equilibrium is established. We obtain the optimal harvesting policy,optimal population equilibrium and the maximal economic value by means of extreme theory.
