The Coupling and Coordination relationship between Ecosystem Service Value and High-quality Development in the counties of lower reaches of the Yellow River Basin

Abstract

[Objective] Analyze the coupling and synergistic relationship between the transformation of county ecosystem service value and high-quality development in the lower reaches of the Yellow River Basin, in order to provide a scientific basis for the development direction of the lower reaches of the Yellow River Basin. [Methods] Build a model of ecosystem service value and high-quality development level in each county in the lower reaches of the Yellow River Basin, and standardize the model using entropy method. (1) Measure the level and changes in the service value of county-level ecosystem services. (2) Measure the switched relationship between the value of different ecosystem services. (3) Evaluate by comprehensively coupling the conversion effect with the index of high-quality development.[Results](1) From 2010 to 2020, the total average value of ecosystem services in 9 cities along the Yellow River decreased by 3.06%. (2) The average values of the high-quality development index of 9 cities along the Yellow River in 2010 and 2020 were 65.60 and 70.53, respectively, with a growth rate of 7.52%. (3) The overall average value of coupling and coordination is 0.295.[Conclusion]From 2010 to 2020, the coupling coordination between the high-quality development level and ecosystem service value of various cities in the lower reaches of the Yellow River Basin was in a low level coupling stage.
