小城市火灾风险评估

摘要

以城市历年火灾数据、城市消防安全布局现状等资料为基础，从火灾发生概率、火灾损失、火灾危险性、防护能力4个方面，应用 AHP 法构建了火灾风险评估指标体系，应用 GIS 空间分析技术，对地块各指标体系按权重进行叠加分析，并以承德县中心城区（下板城）为例，得到城市火灾风险评估图。%Taking urban fire data and urban fire security layout status as bases,starting from four aspects of fire frequency,fire loss,fire hazards and protecting capability,the paper establishes fire risk evaluation index system by applying AHP method,carries out overlay analysis of various index system weight value by applying GIS space analysis technology,and obtains city fire risk evaluation diagram by taking Chengde center city (Xiaban city)as an example.
