    摘要:

    科学评判城镇化质量对于衡量城市发展水平和促进城市可持续发展具有重要意义。研究基于城镇发展和城镇环境质量两个维度构建了辽宁省城镇化质量评价指标体系,综合运用熵权法、标准差椭圆、地理探测器等方法探究辽宁省城镇化质量及空间分布规律、空间演变趋势及影响因子。研究结果表明:①2005-2019年间,全省总体城镇化质量指数呈现上升态势,由2.74提高到4.74,经济城镇化子系统质量上升最大,社会城镇化和环境治理子系统质量上升趋势明显,环境状态和环境压力子系统质量相对平稳。②各市城镇化质量指数在0.087~0.740之间,空间分布上主要呈现沈阳为“大核心”,大连为“小核心”的区域聚集发展的格局。③研究区城镇化质量标准差椭圆重心位于辽阳市,2005-2019年偏转轨迹是“东南-西北-西南”,且标准差椭圆重心移动距离和移动速度逐年增加。④影响辽宁省城镇化质量的子系统主要有经济城镇化、社会城镇化和环境治理因素,具体到指标层上,影响综合城镇化质量的主要有建成区面积、全社会固定资产投资、参加基本养老保险人数、每万人在校大学生数、生活垃圾清运量和城市污水日处理能力,并且指标影响力还在持续上升。

    Abstract:

    Scientific evaluation of urbanization quality is of great significance to measure the level of urban development and promote urban sustainable development. Based on the two dimensions of urban development and urban environmental quality, the evaluation index system of urbanization quality in Liaoning Province was constructed, and the entropy weight method, standard deviation ellipse and geographic detector were comprehensively used to explore the urbanization quality and spatial distribution law, spatial evolution trend and influence factor detection in Liaoning Province. The results show that: (1) From 2005 to 2019, the overall urbanization quality index increased from 2.74 to 4.74, the quality of economic urbanization subsystem has the largest increase, the quality of social urbanization and environmental governance subsystem has an obvious upward trend, and the quality of environmental state and environmental pressure subsystem is relatively stable. (2) The urbanization quality index of each city ranges from 0.087 to 0.740, and the spatial distribution shows that Shenyang is the "big core" and Dalian is the "small core". (3) The center of gravity ellipse of urbanization quality standard deviation in the study area is located in Liaoyang City, and the deflection trajectory is "southeast, northwest, southwest" from 2005 to 2019, and the distance and speed of the center of gravity ellipse of standard deviation increase year by year. (4) Subsystems are mainly affecting the quality of urbanization in Liaoning province economic urbanization, social urbanization and environmental control factors, specific to the index layer, affect the comprehensive index of urbanization area is main, the whole society fixed assets investment, to attend primary endowment insurance number, the number of college students per ten thousand people, the Domestic garbage volume and urban daily sewage treatment capacity, And their influence continues to grow.
