摘　　要：为了研究舆论系统中人员的移动以及存在态度坚定者的因素对舆论形成和演化的影响,建立了相应的元胞自动机舆论模型.在假设人员态度的改变方式遵守少数服从多数的规则下,通过计算机模拟给出了二维四方格子两种影响领域(5邻居、9邻居)在周期性边界条件下的舆论传播行为.模拟给出了模型的演化趋势,以及在不同赞成率的随机初始状态中,模型演化随立场坚定者密度变化的行为.结果表明人员的移动将加快舆论的形成.<Abstrcat> To study the influences of people's mobility and some people with a fixed attitude on the public opinion formation and evolution, we propose a cellular automaton public opinion model. Supposing that the change of people's attitudes complies with the rule that the minority is subordinated to the majority, we present the propagation behavior of public opinion in the two kinds of affected areas on two-dimension square lattice under periodic boundary condition by computer simulation. We also present the evolutionary tendency of the model and the evolutionary behaviors of the model with the change of the density of the people with fixed attitude in the random initial state with different approval rate. Our conclusion is that people's mobility accelerates the formation of the public opinion.
