摘　　要：文中给出单种群阶段结构模型,对成年、幼年种群同时捕获,分别对其幼年种群和成年种群捕获问题,并给出以最大捕获可持续均衡收获(MSY)为目标的最优捕获策略.The paper gives the stage-structure model of single population,which harvests the adult population and young population simultaneously,and gives the optimal harvesting strategies taking the maximum sustainable yield(MSY) as the goal when two stages are harvested respectively.

关 键 词：种群模型 阶段结构 最优捕获努力量
