摘　　要：本文主要介绍一种基于元胞自动机模拟传染病传播的理论模型。人群被分为三类:易感者、染病者和病愈者,每个元胞状态代表某一类人群。特别考虑的是具有垂直传播和一般接触的传染病模型,并进一步考虑了接种疫苗的影响,这种影响能够降低传染病的传播。所提出的模型能够作为其他基于真实数据的模拟实际传染病模型算法研究的基础。The main goal of this work is to present a simple theoretical model, based on cellular automata, to simulate epidemic spreading with the characteristic of vertical transmission. The population is divided into three classes： infected, immunized and suscep- tible. Specifically, we consider the epidemic is the one with the characteristic of vertical transmission. furthermore, the model is extended to include the effect of population vaccination. This kind of effect can reduces the epidemic propagation. The proposed model can serve as a basis for the development of algorithms to simulate real epidemics based on real data.
