鄂尔多斯市生态保护和高质量发展耦合协调状况研究OA

To explore the coordinated relationship between ecological protection and high-quality development in energy-based cities in the Yellow River Basin,Ordos City was taken as an example to study the spatiotemporal evolution characteristics and influencing factors of eco-logical protection and high-quality development from 2001 to 2023.Core indicators were determined through correlation analysis and principal component analysis,and a comprehensive evaluation index system based on the PSR model was constructed.The combined weighting method of EWM-AHP-DEMATEL was used to determine the weights of indicators,the TOPSIS model was employed to calculate the ecological protec-tion index and high-quality development index,and the coupling coordination degree was used to measure the coupling and coordination rela-tionship between ecological protection and high-quality development.The results show that the ecological protection and high-quality develop-ment indices generally exhibit an upward trend,but the growth rate of the ecological protection index slows down due to the marginal dimin-ishing effect of policies,while the high-quality development index fluctuates with economic transformation,showing a trend of first increas-ing,then decreasing,and subsequently increasing again.The coupling coordination degree spatial distribution is low in the west and high in the central and eastern regions.Granted patents per capita,carbon emission intensity,and the proportion of environmental governance invest-ment are the main influencing factors.
