%X 紧急避难场所是应对紧急情况的重要抓手，也是城市防灾减灾体系的重要组成部分。建设好紧急避难场所，有利于防患于未然，保障人民群众的生命和财产安全。本文基于ArcGIS平台，应用网络分析法、缓冲区法，对兰州市城关区紧急避难场所的可达性在500 m有效服务半径和6分钟合理避难时间这两种情况下进行了分析。结果表明，黄河以南、兰山以北、天水路以西的城关区部分区域紧急避难场所建设较好，但城关区紧急避难场所建设存在空间不均情况。本文通过可达性的分析判识出了兰州市城关区紧急避难设施建设不足的区域，并对今后兰州市城关区紧急避难场所的空间布局规划提出了建议。<br />
Emergency shelters are an important tool for dealing with emergencies and an important part of the urban disaster prevention and mitigation system. The construction of emergency shelters is conducive to preventing disasters before they occur and safeguarding the lives and properties of the people. Based on the ArcGIS platform, this paper applies the network analysis method and buffer zone method to analyze the accessibility of emergency shelters in Chengguan District of Lanzhou City, under two scenarios of a 500-m effective service radius and 6-minute reasonable refuge time. The results show that the construction of emergency shelters in some areas of Chengguan District south of the Yellow River, north of Lanshan and west of Tianshui Road is better, but there is a spatial unevenness in the construction of emergency shelters in Chengguan District. The analysis of accessibility in this paper identifies the areas in which the construction of emergency shelter facilities in Chengguan District of Lanzhou City is insufficient, and puts forward suggestions for the spatial layout planning of emergency shelters in Chengguan District of Lanzhou City in the future.
