摘要
考虑捕食者无密度制约和捕获、食饵种群具有非线性密度制约和捕获的一类功能性反应的食饵捕食系统,对其进行定性分析,证明了不稳定的正平衡点附近存在唯一的极限环.
Considering a predator-prey system with a kind functional reaction in which the predator species have no density restriction, while the prey species have nonlinear density restriction and harvest itative analysis is made of it and proved that there exists an unique limit cycle near the positive ~ The qualequilibrium
