- Abstract:
- [Objective]Exploring the temporal and spatial evolution characteristics of the relationship between the carrying capacity of resources and the environment and the level of economic development and the identification of obstacles has important theoretical significance for the construction of regional ecological civilization and sustainable coordinated development. [Methods] This study took Hefei City as the research object, and an index system of Hefei City's resource and environmental carrying capacity and economic development level was constructed. State space method model, coupling model, obstacle degree model and other methods, the coupling coordination degree and evolution process between resource and environmental carrying capacity and economic development level in Hefei City from 2011 to 2020 were calculated and analyzed, and the obstacle factors restricting both were identified. [Results] The index values of Hefei's resource and environmental carrying capacity and economic development level both showed an upward trend, and the resource and environmental carrying capacity and economic development level continued to increase. From 2011 to 2020, the coupling degree between resource and environmental carrying capacity and economic development level was between 0.48 and 0.50, and the type was antagonistic. The level of coupling coordination was between 0.42 and 0.65, showing an upward trend, and had experienced a process of development from mild imbalance to low level coordination and then to good coordination. From the point of view of the identification of obstacles, the obstacle factors restricting the resource and environmental carrying capacity of Hefei mainly came from the environmental capacity factors of the element layer, the obstacles to the economic development level of Hefei mainly came from economic strength and economic structural elements. These three elements were also the key to restricting the coordinated development of resources, environment and economy. [Conclusions] The study of the relationship between the carrying capacity of resources and the environment and the level of economic development and the accurate identification of the obstacle factors can supply the theoretical support for the coordinated development of resources, environment and economy in Hefei City.
