- Abstract:
-
To comprehensively measure the urban sustainable development capacity in northeast China,serve the Northeast Revitalization Strategy,the coefficient of variation TOPSIS method,coupling coordination degree model and ArcGIS technology and other analytical methods were used to construct the urban sustainable development ability evaluation model to study the spatial-temporal evolution of sustainable development capacity and coupling-coordination process and spatial analysis pattern of 34 prefecture-level cities in northeast China from the urban economic,social,ecological environment and comprehensive dimensions. The results showed that:(1)during the study period,the overall urban sustainable development capacity in the three northeastern provinces was generally low,and the sustainable development capability of urban economic,social and ecological subsystems showed different spatiotemporal evolution characteristics in different periods;(2)from the perspective of spatial differentiation,the ‘dual-core' characteristics of Shenyang and Dalian in Liaoning Province were relatively significant; the ‘central-peripheral' characteristics of Jilin Province and Heilongjiang Province were relatively prominent; in general,they were represented by the leading pattern of Shenyang,Dalian,Changchun and Harbin,with significant spatial differentiation characteristics;(3)the economic,social and ecological environment subsystems of 34 prefecture-level cities had a high degree of overall coupling,and the interdependence of subsystems in each city was relatively high,but the level of urban coupling-coordination was low,and many cities faced the dilemma of recession. Improving the overall level of urban sustainable development capability and the coordinated development within cities and sub-systems are the key issues for urban development in the process of comprehensive revitalization of the northeast China in the new era.
