摘要
评估城市区域火灾风险有助于规划城市消防和部署消防力量。为评估城市火灾风险等级,结合城市区域环境、火灾危害和防护能力3个方面,构建火灾风险评估指标体系。利用地理格网和GIS空间分析技术,对各指标体系按其权重进行叠加,并以徐州市为例,得到城市火灾风险等级图。结果表明:徐州市老城区由于人口、建筑密集,火灾风险大;新老城区结合带则因消防力量相对薄弱,火灾风险也较大。基于格网GIS的城市火灾风险评价方法同样适用于其他大中型城市的火灾风险评估。
It was held that evaluating city fire risk could contribute to fire fight programming and fire fight strength deployment in the city. In order to evaluate the grades of urban fire risk, an index system was built according to three aspects including regional environment, fire hazard, protection ability. After various parameters were superimposed using the spatial analysis function of GIS and grid technology, risk evaluation results were revealed on GIS thematic map , and the city＇s present risk rating map was obtained. The results show that the fire risk is great in old urban district of Xuzhou and border area of new and old urban districts, because there are more people and more buildings in the old urban area, border area of new and old urban districts has weaker fire-fighting capacity.
