摘要
对于一类具有简化HollingIV类功能性反应的扑食与食饵模型做了较为详细的定性分析,得到了系统轨线的全局稳定性,极限环的存在性及系统无环的一些充分条件.部分地改进了文献[2]的一些结果.
In this paper, we consider a predator-prey system with simplified Holling type-Ⅳ functional response. Through qualitative analysis of the model in detail, some sufficient conditions for the global stability of the trajectory, existenc and nonexistence of the limit cycle of the system are obtained. It should be pointed out that some results in [2] are improved.
