研究了一类在周期环境中具有脉冲扩散和收获的近远海渔业模型的动力学行为和优化控制问题。利用脉冲微分系统的基本理论和一些分析技巧，研究获得了系统正周期解存在和稳定的条件。进一步，在系统保持周期变化的条件下，考虑收获成本因素，以最大经济净收益为目标，研究收获努力量对收益的影响，获得了最优控制策略及最优经济净收益的具体表达式。

The dynamic behavior and optimal control problem for a class of inshore‐offshore fishery model with impulsive diffusion and periodic coefficients are investigated .By applying the basic theory and some analytic techniques ,the condition w hich ensures the existence and stability of positive periodic solution is obtained .T he species is harvested for economic profit ,the purpose is to control the harvesting effort so as to maximize the profit which is the difference between economic revenue and cost .The exact ex‐pression of the optimal control policy is obtained .
