摘要
讨论了一类具有功能反应函数为x的食饵-捕食系统的收获模型,应用微分方程的定性理论进行分析证明,得到了系统平衡点在全局下是不稳定的,且捕食者将灭绝的结论.
In this paper, a harvesting rate prey-predator system with active function is studied, and some properties of the singular points of the system and its global ability are discussed. By using the differential equation theory, it is proved that predator will be extinct at a certain condition and the system is not global stability.
