非自治脉冲 HollingⅡ捕食系统的研究
Study of a Nonautonomous HollingⅡ Predator-Prey System with Impulses
摘要
Abstract
The dynamical behaviors of Holling II predator-prey system which were disturbed by some effects,coefficients varied and impulses perturbed were studied.Firstly,the dynamical behaviors of sin-gle-species impulses nonautonomous system were discussed,and the permanence and extinction condi-tions of single-species system were analyzed.Further,based on these results and impulsive differential comparison theorem,the system prey extinction and both prey and predator extinction were studied re-spectively,and the permanence of system was discussed,the extinction and permanence conditions of Holling II nonautonomous predator-prey system with impulses were obtained.关键词
