摘要
研究一类具有Holling功能性反应的捕食—食饵两种群同时捕获模型,增加捕获项,推广了文献已有的功能性反应的捕食—食饵两种群模型结果,得到了平衡点稳定的阈值,从生态学的意义上得到了两种群持续生存的充分条件.
Analyzing model of the prey-predator simultaneous harvest with the holling power function increases harvest term and spreads the solutions of the prey-predator model to the original problem. The threshold value of asymptotic stability at the equilibrium points is also got; therefore sufficient conditions of two species persistence are ecologically obtained.
