摘　　要：研究具有捕食食饵系统的捕获优化问题,分别求出该系统的各个平衡点所对应的最大经济效益,通过控制人为捕捞强度,确定了最优的捕获策略,并将其结论推广到一类具有比率型功能性反应的捕食模型.Studied the optimal harvest problem of predator-prey system with density restriction. Separately obtained the maximum economic revenue responding to every equilibrium point. By controlling artificial fishing intensity, get the optimal harvest strategy of the system. The conclusion was extended to a ratio-dependent functional response predator-prey model.

关 键 词：捕食食饵系统 平衡点 最优捕获策略
