摘　　要：基于石家庄都市区2011年1月1日~2017年12月31日的火灾数据,借助GIS空间分析手段,引入不同用地类型,建立火灾危险性评估模型,对石家庄都市区3种用地类型进行火灾危险性评估.结果表明:石家庄都市区居住用地火灾危险性水平最高,商业服务业设施用地次之,最小的是公共设施用地;从空间分布看,都市区商业服务业设施用地和公共设施用地集中分布在中心城区,火灾危险性从中心城区向外呈逐渐增大的趋势,中心城区的居住用地危险性最小,周边地区则较大.评估结果能更全面地反映城市火灾危险性的分布特征,为城市土地利用和消防安全提供参考依据.Based on the fire data of Shijiazhuang metropolitan area in 2011~2017,the GIS spatial analysis method was used,and different types of land use were introduced to establish a fire risk assessment model to assess the fire risk of three types of land use in Shijiazhuang metropolitan area.The results show that the fire risk level of residential land in Shijiazhuang metropolitan area is the highest,the land for commercial service industry is the second,and the smallest is the land for public facilities.From the perspective of spatial distribution,the land for commercial service facilities in urban areas and the land for public facilities are concentrated in the central city.The fire risk is gradually increasing from the central city,and the residential area in the central city is the least dangerous,and the surrounding area is larger.The assessment results more comprehensively reflect the distribution characteristics of urban fire hazards and provide a reference for urban land use and fire safety.
