Measurement and Enhancement Strategies for Regional Logistics Resilience Under Disaster Impact:A Case Study of the July 2023 Extreme Rainstorm and Flood Disaster in the Beijing-Tianjin-Hebei Region
Climate change and unprecedented global shifts have significantly increased the frequency and impact of disasters,posing substantial challenges to logistics systems.This study aims to comprehensively quantify and evaluate the resilience disturbances in regional logistics systems caused by disasters,focusing on the extreme rainstorm and flood disaster that occurred in the Beijing-Tianjin-Hebei region in July 2023.By collecting meteorological data and logistics big data,we identify and analyze the changes in regional logistics network services across three phases:before,during,and after the disaster.We propose a method for measuring logistics resilience and assessing losses,taking into account the spatiotemporal heterogeneity within the affected region.We construct a five-dimensional'5R'logistics resilience evaluation index system and a regional logistics overall resilience measurement index.This'5R'index system includes redundancy,recovery,robustness,resourcefulness,and reconstructability,representing the resilience capacity at different disaster stages.The research finds that the extreme rainstorm and flood disaster caused significant short-term local impacts,resulting in an estimated loss of approximately 30 billion RMB in road freight for the regional logistics system.The overall logistics resilience index for the Beijing-Tianjin-Hebei region is 0.91,indicating a relative high level of resilience.The study recommends continuously enhancing proactive logistics resilience through robust routine operations,pre-disaster capacity redundancy,resistance to disaster impacts,and rapid post-disaster recovery.
