多级洪涝灾害中上海市通勤时空结构韧性测度与优化研究
Resilience of Shanghai's Urban Spatiotemporal Structure under Varying Flood Scenarios
摘要
Abstract
Urban space and function are highly coupled,forming a complex spatiotemporal system that not only accommodates and responds to various urban challenges but also serves as a critical target for enhancing urban resilience and informing planning interventions.Understanding the resilience dynamics of real-world urban systems and their intricate socio-economic effects is fundamental to the development of resilient cities.This study integrates multi-source data,including mobile signalling,road networks,and housing prices,to construct a simulation framework for urban commuting spatiotemporal structures.It further assesses their dynamic resilience characteristics and spatial-social disparities under varying levels of flood scenarios.By identifying resilience bottlenecks,the study proposes targeted planning interventions and applies the framework to Shanghai to unveil regional resilience variations and diverse resilience typologies.The findings indicate that the resilience of urban commuting spatiotemporal structures exhibits multidimensional complexity,with disparities among social strata exceeding those related to gender and manifesting as uneven socio-spatial exclusion effects driven by risk distribution.Moreover,the mitigation of commuting efficiency bottlenecks demonstrates significant temporal sensitivity and spatial heterogeneity,enabling precise intervention targeting.The results validate the effectiveness of the proposed approach,elucidate the flood response mechanisms of Shanghai's commuting spatiotemporal resilience,and offer insights for resilience optimisation and refined urban planning.关键词
