从拮抗到协调:黄河流域省会城市经济社会与资源环境系统的协同演进OA

The ecological conservation and high-quality development of the Yellow River Basin represent a pivotal national strategy.As primary engines of regional development,provincial capital cities are crucial to the basin's sustainable development,where the synergy between their socio-economic systems and resource-environmental conditions is of paramount importance.This study focuses on 9 provincial capital cities within the basin.A comprehensive evaluation index system is constructed to assess both so-cio-economic development and resource-environmental quality.Employing the entropy weight method,a coupling coordination de-gree(CCD)model,and a relative development index are applied to measure and analyze the spatiotemporal evolution of the coordina-tion between these two systems from 2010 to 2023.Results reveal that,in terms of temporal evolution,the overall CCD of provincial capital cities in the Yellow River Basin increased from 0.153 0 to 0.943 0,undergoing a three-stage evolution of"antagonism,adjust-ment,and coordination"with the inter-system relationship gradually improving.The relative development state transitioned from an initial"resource-environment lag"to"synchronous development,"indicating a progressive shift towards dynamic equilibrium.Spatial-ly,a"stronger east and weaker west"divergence pattern is evident.Cities like Chengdu,Xi'an,and Jinan etc.have reached a high-lev-el coordination stage,whereas western cities such as Xining and Yinchuan remain in a state of low-level coordination,underscoring pronounced regional disparities.Therefore,it is necessary to improve the basin-wide collaborative governance mechanism,establish a system-coordinated standard framework,accelerate the optimization and upgrading of industrial structures,develop eco-friendly in-dustries,strengthen the leading role of core cities,and build a basin development community for strategies of development.
