Abstract: Flood resilience is essential for safeguarding human welfare and economic stability by enabling societies to withstand, adapt to, and recover from flood impacts. Traditional engineered measures like levees and drainage systems provide external resilience but often lack long-term sustainability, leading to system failures and ecological degradation. Ecosystems, with their intrinsic adaptive capacities, regulate natural processes and deliver critical flood regulation services, such as water retention and flow control. These services are vital for urban areas where populations and infrastructure are the most vulnerable to flooding. However, a spatial and temporal mismatch exists between the supply of these services. This study introduces an innovative "ecosystem suppl-demand " framework that quantifies the supply and demand of flood regulation services using an index-based approach. By aligning attributes with hazard, exposure, and vulnerability components of the flood resilience index, the framework identifies areas with high flood regulation potential. Spatial and temporal analyses highlight the need for targeted conservation and land-use planning to enhance these services. The findings emphasize the integration of ecosystem services into flood resilience strategies, promoting sustainable, equitable, and effective flood management while preserving ecological integrity.
