摘要
城镇化发展的核心目的是引领城市与生态环境和谐共生,可持续发展。辽宁省作为东北老工业基地之一,研究其城镇化与生态环境质量的协调关系,对于辽宁省城市可持续发展具有重要意义。综合运用耦合度、耦合协调度和地理探测器等方法对辽宁省2005—2019年城镇化与生态环境质量指数、耦合协调度及影响因子进行实证分析。结果表明,2005—2019年辽宁省城镇化与生态环境质量指数为2.44~4.79,总体上升趋势明显,城镇化指数空间上呈沈阳市、大连市为高值核心区域,四周聚集发展的态势,生态环境质量指数呈沈阳市为核心区,周围聚集发展趋势;省级尺度耦合协调度保持稳定上升,局部地区以濒临失调和勉强失调为主,空间分布上呈沈阳市、大连市为高值区域,东西部低的格局;生态环境治理、经济城镇化和社会城镇化子系统所涉及的影响因子对不同时期城镇化与生态环境质量耦合协调度因子探测力值贡献较大,主要影响因子有建成区面积、参加基本养老保险人数、生活垃圾清运量和城市污水日处理能力等。辽宁省城镇化与生态环境质量整体向好发展,耦合协调度有待提高,政府应继续注重生态环境的治理工作,加大环境保护力度,提高人民生活质量。
The core of urbanization strategy is to guide the city and the ecological environment to coexist harmoniously and take the road of sustainable development.Liaoning Province is one of the old industrial bases in northeast China,so it is of great significance to study the coordinated relationship between urbanization and ecoenvironment quality for the sustainable development of Liaoning Province.Coupling degree,coupling coordination degree and geographical detector were used to empirically analyze the urbanization and eco-environmental quality index,coupling coordination degree and influencing factors of Liaoning Province from 2005 to 2019.The results showed that the urbanization and eco-environmental quality index of the province from 2005 to 2019 ranged from 2.44 to 4.79,with an obvious upward trend on the whole.The urbanization index showed a spatial trend of Shenyang and Dalian as the high-value core area with cluster development of surroundings;the eco-environmental quality index showed the trend of Shenyang as the core area with cluster development of surroundings.The coupling coordination degree of provincial scale kept rising steadily,and the regional coupling coordination degree was mainly near disorder and barely disorder,and the spatial distribution pattern was high in Shenyang and Dalian,and low in eastern and western regions.The influence factors involved in the subsystems of ecological environment governance,economic urbanization and social urbanization contribute greatly to the detection power value of the coupling coordination factor between urbanization and ecological environment quality in different periods.The main influencing factors included the built-up area,the number of people participating in the basic endowment insurance,the transportation volume of domestic garbage and the daily treatment capacity of urban sewage.The overall development of urbanization and eco-environment quality in Liaoning Province was good,and the coupling coordination degree needed to be improved.The government should continue to pay attention to eco-environment governance,strengthen environmental protection,and improve people's quality of life.
