具有庇护所效应的R型捕食——食饵系统研究

Research into a Predator-prey System with Rozenweig Functional Response and Prey Refuge

本文主要研究了具有庇护所效应的R型捕食——食饵系统的稳定性.结果表明庇护所效应能够增加两种群的平衡密度,并且最重要的是能够增加系统的稳定性,使得捕食者和食饵能够长期的共存.

In this paper,we mainly study the stability of predator-prey system with Rozenweig functional response and the effect of prey refuge. The results show that the effect of prey refuge can increase the equilibrium densities of prey and predators,moreover,the stability of the positive equilibrium point is also enhanced.
