摘要: 考虑具有替代性食饵及Michaelis-Menten型收获的捕食者-食饵模型. 首先, 讨论其边界平衡点与内部平衡点的存在性和稳定性. 其次, 以
Michaelis-Menten 型收获系数为分支参数, 利用Hopf分支定理证明其内部平衡点处Hopf分支的存在性及其性质. 最后, 利用MATLAB软件进行数值模拟, 验证了理论结果的正确性.

Abstract: We considered a predator-prey model with alternative prey and Michaelis-Menten type harvesting. Firstly, we discussed the existence and stability of its boundary equilibrium points and interior equilibrium points. Secondly, taking the coefficient of Michaelis-Menten type harvesting as the bifurcation parameter, we proved the existence of Hopf bifurcation at its interior equilibrium point and its properties by using the Hopf bifurcation theorem. Finally, we verified the correctness of the theoretical results through numerical simulations by using MATLAB software.

Key words: predator-prey model, Michaelis-Menten type harvesting, alternative prey, Hopf bifurcation, stability
