一类具收获的捕食者—食饵系统的周期解分枝与浑沌现象

Subharmonic Bifurcations and Chaotic Behaviour in the Periodic Time dependent Predator prey System with Constant Harvesting Rates

研究了一类食饵种群具有常数收获率的捕食者—食饵生态系统的周期激励模型，应用Ｍｅｌｎｉｋｏｖ方法，给出了该系统存在浑沌与次谐分枝的某些条件．

Abstract In this paper, we use Melnikovs method to show that the existence of subharmonic bifurcations and chaotic behaviour in the periodic time dependent predator prey system with constant harvesting rates.
