摘　　要：建立并分析了含人工捕获与区域保护的捕食与被捕食模型,得到了平衡解之间的关系,给出了正平衡解存在并全局渐近稳定的条件.A mathematical model for a predator and prey population under the harvesting is proposed and analyzed. The relation between equilibriums has been deduced. The existence of positive equilibrium as well as global stability has been proved based on the proposed model.
