Most studies on fire prevention focus on buildings themselves, such as fire protection facilities, the usage of uninflammable materials, the design of partitions for preventing from fire hazard, etc. However, few researches discuss how to manage fire hazard in community scale concerning surrounding environments, space structure, land use, etc. Recently, urban plans are requested to take hazard mitigation into account. It demands more studies on the urban scale. Hence, this research proposes an evaluation method to assess fire risk degree in terms of urban blocks.

然而，目前一般消防单位对於消防安全之检视大多仅著眼於建筑物内部的消防设备或是建物内部防火设计是否妥当等硬体面，但从都市整体角度，即周边环境、空间结构以及建物、土地使用等因素对於火灾之影响则甚少探讨之，再加上都市防灾计画与检讨中亦须风险的资讯，因此本研究拟就都市街廓尺度，评估其火灾风险度，以作为都市地区消防规划、通盘检讨以及都市更新等政策决定之参考依据。
