摘要
考虑了一类斑块环境下具废弃斑块的捕食—被食模型,确定其平衡点的存在性,通过分析系统雅可比矩阵特征值实部的符号确定其局部稳定性,给出了判定系统平衡点全局稳定性的思路及方法。
In this article, a class predator-prey model with abandoned patches in patchy environment was described. Firstly, the existence of the equilibrium point was determined firstly, and then its local stability was determined by the analysis of the symbol of this system＇s Jacobi matrix value. Finally, the ideas and methods of how to determine the global stability of the equilibrium point were presented.
