捕食者的密度制约和食饵避难所对Lotka-Volterra捕食-食饵模型动力学行为影响的研究
The influence of predator' s density dependence and prey refuge on the Lotka-Volterra predator-prey model
摘要
Abstract
The dynamic behavior of predator' s density dependence for Lotka - Voterra predator - prey model incorporating prey refuge is studied in this paper. By constructing a suitable Lyapunov function, some sufficient conditions are obtained for global asymptotical stability of the interior equilibria and boundary equilibria of the model. The study shows that refuge is a key factor which affects dynamic behavior of the model. When the interior equilibria exist, predator' s density dependence has a major impact on predator and prey population density.关键词
