摘要
研究具有避难所和修正Leslie-Gower项的捕食食饵系统,得到正平衡点存在及全局稳定的条件,探讨了避难所和常数k对系统的影响,特别是对系统持久性和种群数量的影响,得到了些新结论.
A predator-prey model with modified Leslie-Gower and prey refuge is studied.Sufficient conditions for the existence and global stability of the positive equilibrium are obtained.By discussing the influence of refuge and the constant k on the system,specially for the permanence and the amount of the both population,we get some new results.
