Urban　green　space　(UGS)　contributes　significantly　to　urban　settlements　with　respect　to　frequent　rainstorm　events　and　population　agglomeration　issues,　but　there　is　limited　understanding　of　the　spatial　match　between　green　space　supply　and　social　demand.　This　study　established　an　integrated　evaluation　framework　relating　to　the　supply-demand　balance　of　UGS.　In　a　case　study　of　Beijing,　the　urban　waterlogging　risk　was　simulated　with　an　ICM　model,　and　specific　demand　criteria　of　waterlogging　hazards　and　population　needs　were　considered.　The　street-scale　supply-demand　balance　of　demands　for　existing　and　future　UGS　was　then　quantified　with　the　two-step　floating　catchment　area　method.　Comparison　of　the　street-level　balance　in　large　rainstorms　and　populated　areas　identified　the　key　locations　where　the　green　space　supply　should　be　strengthened　in　Beijing.　This　study　may　provide　an　integrated　evaluation　of　green　space　accessibility　and　a　solid　foundation　for　refined　urban　land-use　planning　strategies.
