【Abstract】 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.更多还原
