摘要
目的分析2009-2017年关中城市群脱钩指数的阶段性变化,说明其经济增长与环境压力的时空变化状况,并以此表明该城市群经济可持续发展的时空特征。方法建立Tapio脱钩模型,定量计算关中城市群经济增长与生态环境之间的关系。结果(1)在时序发展特征上,关中城市群脱钩水平整体上稳步发展,在t3时期基本实现经济发展可持续;(2)在空间发展特征上,地区差异不断缩小,脱钩水平表现为轴带状和团簇状聚集。结论脱钩状态的变化主要有赖于经济增长的变化,即经济发展是关中城市群经济可持续性发展的主要推动力。
Purposes—To analyze the phased changes in the decoupling index of the Guanzhong urban agglomeration from 2009 to 2017,to illustrate the temporal and spatial changes in economic growth and environmental pressure,and to show the temporal and spatial characteristics of the sustainable economic development of the urban agglomeration.Methods—The Tapio decoupling model was established to quantitatively calculate the relationship between the economic growth of the Guanzhong urban agglomeration and the ecological environment.Results—(1)In terms of temporal development characteristics,the decoupling level of the Guanzhong urban agglomeration has developed steadily as a whole,with sustainable economic development achieved during the t3 period;(2)In terms of spatial development characteristics,regional differences are constantly reducing,and the decoupling level is manifested as an axis belt and clusters.Conclusion—The changes in the decoupling state mainly depend on changes in economic growth,that is,economic development is the main driving force for the sustainable development of the Guanzhong urban agglomeration.
