摘要
主要研究了具有Holling Ⅳ型功能反应的三维顺环捕食离散系统,并且运用差分方程的比较原理和数学分析方法,得到了该系统一致持久的充分条件.
The paper discuss three-species clockwise chain predator-prey system with Holling Ⅳ functional responses.By applying the comparison theorem of difference equation and the mathematical analysis method,sufficient conditions are established for the permanence of the obtained results.
