摘　　要：依据北方某城市供水管网2006年—2008年的爆管数据,以ArcGIS 9.2为软件平台建立了供水管网爆管数据库,并提出了两种供水管网爆管空间分析方法,分别建立了供水管网爆管的空间叠置分析模型和缓冲区分析模型。由空间叠置分析结果可确定供水管网发生爆管可能性的空间分布;而由缓冲区分析结果可知,供水管网爆管的发生具有空间积聚性。According to the pipe break data of the water supply system in a northern city between 2006 and 2008, a pipe break database was established based on the ArcGIS 9.2, and two spatial analysis methods for pipe break of the water supply system were proposed. The spatial overlay analysis model and the buffer analysis model for pipe break of the water supply system were built. The spatial distribution of the pipe break possibility can be determined using the spatial overlay analysis model, and the spatial clustering of the pipe break can be known using the buffer analysis model.
