摘要
对离散的捕食—食饵系统的奇点进行了定性分析 ,从生态学的意义上解释了平衡点外围周期解的存在性 ,稳定性。另外 。
The equilibrium points of discrete prey-predator systems are analyzed qualitatively.The esistence and stability of the periodic solutions around the equilibrinm pointsare interpreted ecologically.In addition,Conditions of maximum sustainable economic revenue is provided when two species of prey-prdeator discrete systems are harvdetde simultaneously.
