摘要
研究一类食饵具有避难所的非自治修正Leslie-Gower捕食-食饵系统.借助于微分方程比较原理和通过构造适当的Lyapunov函数方法,得到了保证系统持久和全局吸引性的充分性条件.
A nonautonomous modified Leslie-Gower predator-prey system incorporating a prey refuge is studied in this paper.By applying the comparison theorem of differential equations and constructing a suitable Lyapunov function,we obtain a set of sufficient conditions which guarantee the permanence and global attractivity of the system.
