摘 要: 讨论了疾病仅在食饵中传播的捕食者-食饵模型.假设捕食者只捕食染病的食饵种群,且疾病的发生率为非线性的.本文首先讨论系统解的有界性,然后讨论系统平衡点的存在性及其存在时的稳定性,得到了边界平衡点和正平衡点的全局稳定性. In this paper,we study the predator-prey model with disease in the prey. Assume that the predator eats only the infected prey, and the incidence rate of disease is saturated. First of all, we study the boundedness of solutions,then we discuss the existence of equilibrium and its stability, and obtain the global stabilities of boundary equilibrium and positive equilibrium.
