| 摘 要： | 城市区域火灾风险评价是城市消防资源优化配置的基础,本文在研究火灾风险影响因素与空间及地类关系的基础之上,将GIS技术引入城市火灾风险评价领域,构建了基于地理网格的地类火灾风险扩散模型。并以徐州市区为例,通过对各影响因素的空间地类阻隔扩散分析与叠加分析,得出任意分辨率网格的火灾风险等级,为未来城市的火灾预警与资源优化提供一种新的思路。

| Abstract: | City fire risk evaluation is the basis of optimal distribution of city fire fighting resources.By applying GIS technology and researching the relationship between fire risk influential factors and space as well as land types,fire risk diffusion model of land types was constructed on the basis of geographic grid in the paper.Taking Xuzhou city as an example,fire risk level of each resolution grid was figured out through the analysis of spatial land types block diffusion and overlay of all influential factors,which could provide a reference to thinking for the city fire risk early warnings and resource optimization. |
