摘要
近年来,全球气候变化背景下城市洪涝灾害呈现频发态势,我国城镇化进程中的洪涝风险日益凸显,城市洪涝韧性亟待提升。为系统评估城市洪涝韧性并识别其短板,文章采用可靠性、鲁棒性、恢复速度、弹性四维分析框架,充分考虑城市洪涝韧性“预防—抵抗—恢复—适应”关键环节,构建了一套多维度、全周期的城市洪涝韧性体检指标体系,并在此基础上提出城市洪涝韧性提升策略,以期为系统识别城市洪涝韧性薄弱环节、科学提升城市洪涝防治韧性提供基础支撑。
In recent years,urban flood disasters have become more frequent under global climate change,and flood risk has intensified with China's rapid urbanization,highlighting an urgent need to enhance urban flood resilience.To support systematic assessment and diagnose key weaknesses,this study develops a multi-dimensional,full life-cycle indicator system for urban flood resilience using a four-dimensional analytical framework—reliability,robustness,recovery speed,and adaptability—while explicitly accounting for the critical stages of“prevention-resistance-recovery-adaptation”.Based on the proposed indicator system,corresponding strategies are further suggested to strengthen weak links and provide technical support for scientifically improving urban flood resilience.
