摘　　要：城市危险源分布范围较广,有些还以线状和网络状分布在人口、公共设施集中的区域。在地震的作用下,城市中潜在的危险源对地震次生火灾的起火和蔓延都有着重要的影响。着重研究了城市中危险源对地震次生火灾起火的影响,并建立了基于元胞自动机的城市区域火蔓延概率模型。模拟结果再现了火蔓延的过程,不仅提高了人们对城市区域火蔓延危害的认识,而且为城市危险源纳入城市布局和城区建设规划设计提供了依据。The city hazards are widely distributed and a lot of them distributed in the region where population and public facility are concentrated. The city hazards have a great effect on the post-earthquake fire ignition and spreading. The effect of city hazards on post-earthquake fire was studied. A fire spreading probability model of city district based on cellular automata was developed. The fire spreading process was reproduced successfully by the model. The reproduction of fire process can not only improve the people＇s cognition, but also provide the certain basis for city planning.
