摘要
老旧小区是城市在面对自然灾害和突发事件时的典型脆弱区域,其应急疏散空间在城市防灾减灾中起到关键作用。从老旧小区存量空间出发,结合耦合协调度模型,从平时使用情况、灾时使用情况以及平灾转换能力识别了平灾结合的应急疏散空间特征。将空间分为平灾结合核心空间、重要空间和次要空间,以成都市华阳街道正大街片区的多个老旧小区为例进行实例研究,针对三类空间特性提出优化建议,为其他老旧小区应急疏散空间建设提供参考。
Old residential areas are typical vulnerable regions in cities when facing natural disasters and emergencies,and their emergency evacuation spaces play a crucial role in urban disaster prevention and reduction.This study begins with the existing spaces in old residential areas and employs the coupling coordination degree model to identify the characteristics of emergency evacuation spaces that integrate regular and disaster-specific functions,including normal use,disaster use,and the capability for transition between the two.The spaces are categorized into core disaster-relief spaces,important spaces,and flexible spaces.A case study was conducted on several old residential areas in the Zhengda street area of Huayang street,Chengdu.Based on the findings,optimization suggestions for the three types of spatial characteristics are proposed,providing a reference for constructing emergency evacuation spaces in other old residential areas.
