摘　　要：讨论了一类捕食者带有传染病的生态-流行病模型,考虑由于种群迁移加入交错扩散项对应的问题,应用最大值原理和Harnack不等式给出该问题正平衡解的上下界估计.An eco-epidemic model of a predator with an infectious disease is discussed. Considering the problemthat the population migration is added to the interlaced diffusion term,the upper and lower bounds of the positiveequilibrium solution of the problem are given by using the maximum principle and the Harnack inequality.

关 键 词：生态-流行病模型 交错扩散项 正平衡解 上下界估计
