石家庄市公共空间韧性承涝能力评估与提升策略研究

Study on the Strategies for Evaluating and Improving Public Space Resilience Waterlogging Capacity in Shijiazhuang City

在城市化进程加快背景下,城市暴雨内涝问题日趋严重,随着韧性理念的发展,基于韧性视角寻找可承涝的城市空间已成为改善城市雨涝的新思路。文章以石家庄市为例,通过耦合城市公共空间与石家庄市雨涝淹没风险的分布,探究城市既有公共空间承涝能力与公共空间体系承涝现存问题,并针对不同公共空间类型,从提高公共空间承涝体系的抗扰性、加强恢复的快速性两个方面,提出了具有针对性的承涝韧性提升策略,为石家庄市城市承涝能力的提高与公共空间雨涝韧性的增强提供了新思路。

Under the background of accelerated urbanization,the problem of urban rainstorm waterlogging is becoming more and more serious.With the development of the concept of resilience,it is a new way to improve urban rain and waterlogging to find urban space that can bear waterlogging from the perspective of resilience.Taking Shijiazhuang as an example,by coupling the distribution of urban public space and the risk of waterlogging inundation in Shijiazhuang,this paper explores the existing problems of urban public space bearing capacity and public space system,and puts forward targeted strategies to improve the resilience of public space bearing capacity from two aspects of improving the antiinterference capacity of public space and strengthening the speed of recovery,which provides a new idea for the improvement of urban flood prevention ability and the enhancement of the waterlogging resilience of public space in Shijiazhuang.
