摘要
研究了具有收获率的HollingⅡ类功能性反应系统,讨论了该系统平衡点的存在性和性态,通过构造Lyapunov函数,证明了系统唯一正平衡点是全局稳定的.
Studied the predator-prey system of Holling Ⅱ functional response with harvesting rate,the existence and properties of equilibriums in the system was discussed.By constructing Lyapunov function,obtained the global stability of unique positive equilibrium.
