摘　　要：协调土地利用和经济发展是一个城市实现可持续发展的关键。基于淮河生态经济带2006~2020年25个地级市面板数据,引入脱钩指数模型,从时间、空间两个维度考察淮河生态经济带城市用地扩张与经济增长间的耦合关系。结果显示:淮河生态经济带城市用地扩张与经济增长的脱钩关系大体上呈现出强脱钩、弱脱钩、增长连结、增长负脱钩4种状态,其中以弱脱钩状态为主;纵向视角,城市经济增长对建设用地的依赖程度相较于前期有所降低,近两年的城市脱钩状态呈现向强脱钩和增长负脱钩两级发展的微弱态势;横向视角,区域发展不平衡,城市间脱钩状态差异显著。基于测算结果,将25个城市归类为脱钩理想型、脱钩一般型和脱钩不理想型三类脱钩城市。在上述分析基础上,认为城市应该坚持推进产业转型升级,合理界定城市边界,加快人口城镇化进程,持续减弱对土地财政的依赖度。Coordinating land use and economic development plays an important role in achieving sustainable urban development.Based on panel data of 25 prefecture-level cities in Huaihe Eco-Economic Zone from 2006 to 2020,this study introduced a decoupling index model to examine coupling relationship between urban land expansion and economic growth in time and space dimensions.Results show that the decoupling relationship is generally characterized by four states:strong decoupling,weak decoupling,growth linkage and negative decoupling,with weak decoupling being the main one.In past two years,decoupling of cities showed a weak trend,but towards a strong decoupling and negative decoupling.Based on measurement results,25 cities are classified into three types of decoupling:ideal decoupling,average decoupling and undesirable decoupling.Based on above analysis,it is suggested that cities persist in promoting industrial transformation and upgrading,reasonably defining urban boundaries,accelerating the process of urbanization of population and continuously reducing the dependence on land finance.
