摘要
[目的]研究陕西省10个地级市的经济实力与环境承载力的协调度,为未来城市经济发展提供一定的理论参考。[方法]运用熵值法构建经济实力和环境承载力的指标体系,结合耦合协调度模型对经济和环境之间协调度的发展趋势进行研究,并借助ArcGIS工具对二者的空间格局进行探讨。[结果](1)陕西省10个地市的经济发展和环境承载力发展趋势呈现总体上升且稳定发展的态势,各个城市的环境承载力水平较高,发展速度差别不大且波动幅度小。(2)2005—2014年10个城市经济实力与环境承载力的耦合度和耦合协调度变化趋势基本相同,呈缓慢上升趋势;耦合协调度的空间组合不同,陕西省北部和中部城市经济发展和环境承载力的耦合协调度较高,南部城市耦合协调度水平低。[结论]陕西省10个地市经济实力与环境承载力协调度总体差异大,省会西安市所处的关中地区发展好,陕北地区次之,陕南地区的安康市和商洛市经济实力较弱。
[Objective] The objective of the study was to analyze the degree of coordination between economic strength and environmental bearing capacity of 10 cities in Shaanxi Province, and to provide certain theoretical reference for city economic development in the future.[Methods] Using entropy value method, index systems of economic strength and environmental bearing capacity were built. And the coupling coordination degree model between economy and environment was also used to study the evolution trend of coordination degree. Tools of ArcGIS were applied to discuss the spatial pattern of them.[Results] （1） The development trends of economic development and environmental bearing capacity of 10 cities in Shaanxi Province were stable inclined. The levels of the 10 cities environmental bearing capacity were all at fluctuated high level and had no obvious gap. （2） The coupling coordination degree from 2005 to 2014 had the same slow rising trend. The space combination of coupling coordination degree was different. The coupling degree of economic development and environmental carrying capacity of the cities in northern and central Shaanxi Province was relatively high, while that of the southern part was low.[Conclusion] The 10 cities＇ economic strength and the coordination degree of environment capacity were significantly different on the whole. The development of provincial capital city of Xi＇an in Guanzhong Region was fast, the development of Northern Shaanxi Province followed, while cities of Ankang and Shangluo Region developed comparative slowly.
