Abstract：Small and micro water bodies are crucial spaces for urban rainwater storage and flood regulation.Aiming to enhance urban resilience to rainwater flooding,this study focuses on small and micro water bodies,proposes a planning approach based on the"source-flow-sink"theory.The approach includes analyzing current rainwater flooding conditions,identifying and evaluating"source-flow-sink"spaces,and guiding the protection and construction of small and micro water bodies.This spatially-oriented approach avoids the spatial mismatches often associated with total control methods.An empirical study is conducted in the downtown area of Bengbu City,Anhui Province,to demonstrate the application of this approach.The study aims to provide technical support for the layout and protection of small and micro water bodies in the context of national land spatial planning,offering a reference for urban water system protection.
