摘　　要：为研究燃气管道泄漏爆炸后的应急救援物资需求量和最佳救援点选址,采用案例推理方法,建立了燃气管道泄漏爆炸事故应急资源需求模型。以某化工园区发生燃气管道泄漏爆炸为案例,运用MATLAB编程对应急资源需求进行数值计算;利用ArcGIS可视化、地图数据分析功能,建立网络空间数据集,获得该案例工业园区6个应急救援点。结果表明,可通过化工园区应急救援历史数据获得事故应急资源需求量,利用ArcGIS建立位置分配点和确定救援点数量,可获得优化的应急救援选址。To study the demand for emergency rescue materials and optimal rescue point selection after a gas pipeline leakage and explosion,this paper uses a Case-Based Reasoning(CBR)method to establish an emergency resource demand model for gas pipeline leakage and explosion accidents,and conducts a case study of a gas pipeline leakage and explosion accident in a chemical industrial park.Firstly,this paper collected key elements of historical accidents such as the number of casualties,affected area,and accident grade and unified their dimensions.MATLAB programming is used to determine the source case with the highest similarity to the target case and obtain the proportional reasoning calculation of the emergency resource demand of the target case.Secondly,this paper used the functions of ArcGIS visualization and spatial network analysis to perform buffer zone overlay analysis on the distribution structure of explosion release sources and roads in the industrial park.Meanwhile,ArcGIS interpolation analysis method is used to obtain the risk distribution map of gas explosion accidents in the park,and the comprehensive accident risk map is divided into five levels using natural breakpoint segmentation.The intersection of the erased and merged buffer zone and the high-risk area of gas is the initial location for emergency rescue.Finally,this paper established a network spatial data set to allocate rescue points for high-risk areas in the initial location.Taking into account road conditions and individual differences,six accident emergency rescue points were set up in the industrial park.A range within 5 km was considered an effective rescue range to ensure that emergency supplies can be supplied on time.The results show that the chemical industrial park can optimize the selection of emergency rescue sites by obtaining the demand for emergency resources from historical data on emergency rescue,and by using ArcGIS to establish emergency resource location allocation points and determine the number of rescue points.
