摘要
为研究收获率参数对生物系统稳定性的影响,对捕食者-食饵模型引入收获率参数,对其进行稳定性分析,计算出捕食者带收获率参数的捕食系统的平衡点和发生Hopf分岔的条件,给出其在第一象限的平衡点定理和在特定值下的鞍结分岔图以及Hopf分岔图。
In order to study the influence of the harvest rate parameter on the stability of the biological system,the harvest rate parameter was introduced to the predator-prey model,and the stability analysis was performed to calculate the equilibrium point of the predator-predator system with the harvest rate parameter and the Hopf bifurcation.The conditions of the equilibrium point theorem in the first quadrant,the saddle knot bifurcation diagram and the Hopf bifurcation diagram under a specific value are given.
