摘要：

A predator-prey model with Holling type II functional response incorporating a constant prey refuge is investigated. Depending on a constant prey refuge m, which provides a condition for protecting m of prey from predation, we show the instability and global stability properties of the equilibria and the existence and uniqueness of limit cycles for the model. Two examples are carried out to illustrate the validity of our results. (C) 2008 Elsevier Ltd. All rights reserved.
