摘要
对食饵种群具有常数贮存的捕食者-食饵模型进行了定性分析,得到了正平衡点全局稳定性的条件和绕正平衡点的极限环的存在唯一性的条件。实际例子表明本文的结果有广泛的应用价值。
The qualitative analysis of predator-prey model with constant-rate prey stocking is discussed . Conditions respectively for the global stability of positive equilibrium point and for the existence and uniqueness of a limit cycle around the positive equilibrium point are obtained . Concrete instances show that the results of this paper can be widely applied .
