The rapid development of urbanization brings pressure on the city,resulting in resource shortage,environmental pollution and other issues,which restricts the sustainable development of the city.Resources and environmental problems are also important factors that restrict the sustainable development of Chengdu-Chongqing Urban Agglomeration.Based on the DPSIRM model,this paper constructs the evaluation index system,integrates the GMD-GRA-TOPSIS model to compare the carrying capacity of resources and environment of the Urban Agglomeration from 2010 to 2020,and then uses the grey predic-tion model to early warn the future carrying capacity of resources and environment.The results show that the trend of carrying capacity of resources and environment in the Urban Agglomeration from 2010 to 2020 is different,and there is a certain carry-ing capacity of resources and environment in these areas.Spatially,adjacent cities have direct effects,geographical proximity is more likely to be affected by each other,and distant cities have indirect effects on each other,plausibly influenced by upper higher-level policies,regional development planning,etc.According to the early warning evaluation,the overall situa-tion of resource and environment carrying capacity of the Urban Agglomeration in 2025 is relatively stable,and there is a trend of improvement in some areas,which provides effective improvement ideas for urban development.
