摘要
研究了一类食饵具有密度制约且具有群体防御能力的捕食系统,通过定性分析,得到了平衡点的稳定性及极限环存在的充分条件等若干新结果。这些结果为进一步研究此类系统提供了可靠的理论依据。
In this paper, a predator-prey system while prey has density dependence and group defense ability was discussed .By qualitative analysis, the author obtained sufficient conditions for stability of equilibrium points and for existence of limit cycles of the system .These new results provide a reliable theoretical foundation for making further study on this class of system.
