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.
