日本有许多建筑区，旧木结构的比例很高。一旦发生地震灾害，这些地区将因建筑物倒塌和火灾蔓延而受到严重破坏。因此，政府正集中精力改善这些领域。为了促进这种改善，需要通过社区规划，在居民和政府之间建立防灾对策的共识。本研究开发了一个模型，作为规划支持工具，可以直观地模拟火灾的蔓延。该模型采用元胞自动机技术，将火灾发生过程与火灾蔓延过程相结合，能够真实地反映建筑物密集区火灾蔓延的详细过程，并将该模型应用于日本某历史建筑物密集区。基于模型的模拟结果和日本建成区的实际火灾记录，模型的校准和再现性进行了检查和审查。从这一过程的结果来看，我们相信，在合作规划过程中，在检查当地环境改善的效果时，使用模拟结果是有价值的。(C)2006爱思唯尔有限公司版权所有。
Japan has many built-up areas with a high proportion of old wooden structures. These areas will be badly damaged by collapsed buildings and the spread of fire in the event of a seismic disaster. The government is therefore focusing on the improvement of these areas. For the promotion of such improvement, there is a need to build consensus for disaster prevention countermeasures through community-based planning by both the residents concerned and the administration.In the present study, we developed a model as a planning support tool that can visually simulate the spread of fire. This model incorporates firefighting activities and can realistically show the detailed fire spreading process that traditional models cannot represent in built-up areas, using cellular automata.The model was applied to a historical built-up area in Japan. Based on the simulation results obtained by application of the model and the actual fire records of Japanese built-up areas, the calibration and reproducibility of the model were examined and reviewed. From the outcome of this process, we are confident that the use of simulation results is of value when examining the effects of improvements in the local environment during the collaborative planning process.
