摘要
建立并分析了具有扩散的近海海域捕鱼收获模型,得到了正平衡点全局稳定的条件,给出了以最大可持续均衡收获为目标的最优捕获策略.
In this paper,we propose and analyze a inshore-fishing model with diffusion and obtained sufficient conditions for the extistence of global stable positive equilibrium.Furthermore,we considered the optimal fishing policy and provide theories for the development management of renewable resources.
