摘要
讨论一类食饵具有群体防御能力且两种群均有密度制约项的捕食系统.通过定性分析,得到了平衡点的存在条件,证明解的有界性,得到系统的全局稳定性及极限环存在唯一性的充分条件.
This paper considers a class of predator with group defence capability. By qualitative obtained, and the boundness of the solutions trajectory, and the existence and uniqueness prey dynamic system with double density restriction and prey analysis of the model, the existence condition of equilibuium is are proved, the sufficient condition of the global stability of the of limit cycle of the system are obtained.
