Spatial-Temporal Evolution of Coupling and Coordination Between Urbanization Efficiency and Ecological Environment Quality in Anhui Province
Research on the coupling and coordination relationship between urbanization efficiency and ecological environment quality is helpful to explore their essential relationship,and can provide a scientific basis for coordinated regional development.In this paper,the urbanization efficiency and ecological environment quality level of 16 cities in Anhui Province were measured by constructing a comprehensive evaluation system,and the coupling coordination level and spatial pattern characteristics of urbanization efficiency and ecological environment quality were analyzed by using coupling coordination degree and spatial autocorrelation model.The results showed that:①From 2005 to 2020,the average urbanization efficiency of Anhui Province increased from 0.937 to 1.055,and the number of effective decision-making units accounted for 77.3%,which showed the characteristics of radiation to the northwest-southeast direction centered on Hefei and Tongling.②The ecological environment quality index of Anhui Province showed a fluctuating and rising development trend,with the average value of the index rising from 0.217 to 0.413,and the spatial distribution pattern was"high in the south and low in the north".③The coupling degree and coupling coordination degree of urbanization efficiency and ecological environment quality in Anhui Province showed an upward trend,and the coupling degree was in the coupling stage,and the coordination degree was mainly medium coordination type.However,there were obvious differences between cities,which restricted the coordinated development of the region as a whole.④The degree of coupling coordination showed a strong positive correlation in space,with the high-high and low-high agglomeration areas concentrated in the southern part of Anhui Province,and the low-low agglomeration areas distributed in the northern region.In order to promote the coordinated development of regional urbanization efficiency and ecological environment quality,the government should formulate development strategies according to local conditions,implement the concept of green development,actively promote industrial transformation,and promote regional benign development by optimizing resource allocation.
