Abstract：Withthe acceleration of urbanization and the effects of global climate change，urban flooding has become increasingly frequent.Basedonan extensive literature review，a vulnerabilityindex system comprising seventeen indicators was constructed toassssurban flooding vulnerabilityin thirteen prefecture-level cities in Jiangsu Province.The combination weighting method basedon game theory was apliedto determine thevulnerability levels.The results indicatetattorrentialrinfallfrequency，valueaddedofte tertiaryindustry，GDPperunitlandarea，populationdensity urbanizationrate，impervioussurfaceratio，andpercapitaroadareaarekeyindicatorsinevaluatingvulnerability.
