摘      要：Due to the complexity of sustainable urban research,the environmental sustainability was *** the sponge city as an example,the case study was conducted based on the integrated geographic information system(GIS)and emergy *** results demonstrate that the emergy of agricultural crops,major industrial products,comprehensive energy products,imports and exports,waste products and increased natural system emergy are the decisive factors for the sustainability *** crops are the primary contributor,which accounts for 48.9%of the total emergy *** solid waste has a self-evident superiority in the waste products emergy *** water and vegetal biomass emergy possess the pivotal consequences,far higher than soil organic *** sewage treatment stations(0.11%)play a small role in the sustainability assessment of the sponge *** emergy sustainability index is 0.02181,which indicates poor environmental *** to the study results,increasing renewable energy input proportion and adopting the vegetal biomass of high unit emergy values(UEVs)can improve the sustainability level.
