| 摘 要： | 以目标泛函为基础，应用最大值原理讨论了开放式渔业的最优控制问题．进而得出了鱼群的最优种群密度z^＊和最优收获率h^＊；并进一步分析了贴现率δ对最优收获量的影响．最后应用了一个建立在Schaefer模型上的例子．

| Abstract: | With the application of maximum principle that based on the objective functional, the optimal control problem of the open-access fishery was discussed. The optimal population density x＊ and the optimal harvest rate h＊ were obtained; and the discounting rate δ was further analysised on the impact of the optimal harvest. The application of an example was put up based on Schaefer model. |
