Assessment of waterlogging resilience in Beijing based on quantification of economic losses under climate change
Based on the InfoWorks ICM urban waterlogging model and coupled with the economic loss calculation of waterlogging,the system performance curve of Beijing was characterized under different climate scenarios in the future and rainfall recurrence periods.A dynamic assessment system for waterlogging resilience in Beijing was established,taking into account the resistance,adaptability,and resilience of waterlogging.The impact of future climate change on waterlogging resilience in Beijing was quantitatively evaluated.The results show that under the combination scenarios of SSP2-4.5,SSP3-7.0,and SSP5-8.5 climate change and rainfall recurrence periods of 5,20,50,and 100 a,respectively,Beijing has a higher level of waterlogging resilience.Among different land use types,industrial areas have the highest resilience level,while residential areas have the lowest resilience level.The waterlogging resilience level of Beijing inner ring area is significantly lower than that of the outer ring area.
