韧性城市视角下的小城镇地下空间防灾韧性评估研究——以安徽绩溪县为例

Resilience Assessment of Underground Space Disaster Prevention in Small Towns from the Perspective of Resilient City:A Case Study of Jixi County,Anhui Province

近年来,防灾减灾功能不足己经成为新常态下我国城市的主要特征。地下空间作为缓解城市各类矛盾的“缓冲区”和资源“承载体”,是我国建设韧性城市的重点区域。文章从应灾全过程中的灾前、灾中和灾后三个阶段构建小城镇地下空间韧性防灾评估模型,对绩溪县地下空间进行韧性评估并提出优化策略。

In recent years,the insufficient function of disaster prevention and reduction has become the main feature of Chinese cities under the new normal.Underground space,as a"buffer zone"and a"carrier"of resources to alleviate all kinds of urban contradictions,is the key area of building resilient cities in China.In this paper,the evaluation model of resilience of underground space in small towns is built from the three stages of predisaster,mid-disaster and post-disaster in the whole process of disaster response.The resilience of underground space in Jixi County is evaluated and the optimization strategy is put forward.
