Urban　green　spaces　(UGS)　can　mitigate　urban　waterlogging　disasters　and　improve　subjective　well-being.　The　study　presents　an　integrated　framework　combining　subjective　and　objective　perceptions　to　assess　the　socio-economic　value　of　UGS,　using　InfoWorks　ICM　model　and　the　Life　Satisfaction　Approach.　Central　Beijing　was　selected　as　a　case　study.　From　the　objective　perception　perspective,　UGS　significantly　mitigated　waterlogging　risks,　particularly　in　low　and　high　rainfall　return　periods,　with　green　space　hotspots　overlapping　with　areas　of　severe　waterlogging　risk.　From　the　subjective　perception　perspective,　women,　younger　groups,　and　non-car　owners　perceived　a　stronger　relationship　between　UGS　and　waterlogging　based　on　CGSS　2021.　The　waterlogging　mitigation　value　of　UGS　was　largely　undervalued,　with　67.33　%　of　the　total　value　coming　from　indirect　effects.　During　the　5-year　rainfall　return　period,　the　reasonable　threshold　of　UGS　area　was　33.36　km²,　and　each　household　was　willing　to　pay　1.3468　RMB/m2　($0.1921).　©　2024　Elsevier　B.V.
