以上海市嘉定区、金山区避难场所规划为例，对城市避难场所规划的3方面问题进行了思考。第一，避难场所规划编制过程中涉及的问题。灾害类型决定疏散原则，进而影响避难场所的布局；避难需求和服务半径决定避难协调组规模和用地。第二，影响避难场所服务水平的问题。避难行为和人口密度决定避难场所分布，城镇地区和乡村地区由于人口密度不同，需要建立针对化的避难体系；避难场所的外部选址影响服务范围，内部设计影响服务效率。第三，影响避难场所实施效果的问题。避难人群的需求影响场地型和场所型配置比例；时序协调和建设主体协调影响行动计划，需要形成“空间上有位置、建设上有时序、实施上有主体”的避难场所建设的行动项目库。%This paper analyzes three problems on shelters planning in Jiading and Jinshan District.
