ABSTRACT
In this study, a comprehensive model for suitable carrying capacity of resources and environment was proposed based on ecological footprint method. Using the spatiotemporal distribution data of land use in Chongqing Section of Three Gorges Reservoir Area from 2001 to 2016, the response changes of carrying capacity of resources and environment under the evolution of land use structure were investigated. The analytical results showed that the suitable carrying capacity of resources and environment in Chongqing decreased first and then increased. In the early stage of the Three Gorges Project, some districts and counties exhibited the phenomenon of suitable carrying capacity deficit, especially in the northeast of Chongqing. In the main urban area of Chongqing, the suitable carrying capacity was also mainly restricted by the ecological resources conditions, the deficit was getting worse with the increase of population density. In the later stage, by restoring ecology and improving the living and economic conditions, the phenomenon of deficit was gradually alleviated. These findings will provide some references for the protection of ecological environment and the development of social economy in Chongqing Section of the Three Gorges Reservoir Area.
