摘要:

品质城市建设是响应生态文明、高质量发展与新型城镇化战略的重要内容。以兰西城市群30个市(县)为研究对象,以城市建成区为基本空间单元,从用地、经济、社会、生态、环保、交通、市政和形象品质8个维度进行了兰西城市群品质城市建设水平评价研究。结果表明:(1) 在时序变化上,各城市的综合品质整体持续提升,品质建设处于相对中低水平;各城市的分维度品质变化复杂,存在稳定型、提升型、先降后升型、先升后降型、混合型等多种变化类型。(2) 各城市综合品质在空间上呈现由“双核”向“多核共存”格局转变的特征;分维度品质差异大,分布不均衡。(3) 各城市分维度品质的贡献差异显著,特色品质城市逐步形成,基本形成单维度、双维度和多维度主导型3种类型。(4) 品质城市的影响因素较多,其影响力为建成区规模>人口规模>人均GDP>城镇化率>对外交通>地形起伏度,城市规模是兰西城市群品质城市建设的主要影响因素,城镇化率和人均GDP为次要影响因素,自然因素影响最弱,但属于基础性作用。

Abstract:

The construction of a quality city is an important part in response to the strategy of ecological civilization, high-quality development, and new urbanization. This paper investigates the evaluation of quality city construction level of Lanzhou-Xining urban agglomeration, northwest China from eight dimensions of land use, economy, society, ecology, environmental protection, transportation, municipal administration, and image quality using 30 cities (counties) of Lanzhou-Xining urban agglomeration as the research object and urban built-up area as the basic spatial unit. The results show that: (1) In terms of time series, the overall quality of each city continues to improve, and the quality construction is at a relatively low level; Each city’s change in sub-dimension quality is complex, and there are many different types of change, such as stable type, promotion type, first-decline-and-then-rise type, first-rise-and-then-fall type, mixed type, and so on. (2) The change in space pattern from “double core” to “multi-core coexistence” characterizes the comprehensive quality of each city. The quality difference of the dimension is large and the distribution is not balanced. (3) There are significant differences in the contribution of sub-dimension quality among cities. Identifying feature cities emerge gradually, dividing into three types: single dimension, two-dimension, and multi-dimension dominant. (4) There are numerous factors that influence the quality of a city, in a series as built-up area size>population size>per capita GDP>urbanization rate>external transportation>topographic relief. City scale is the main influencing factor of quality city construction in Lanzhou-Xining urban agglomeration, urbanization rate and per capita GDP are the secondary influencing factors, and natural factors are the weakest, but they belong to the basic role.

Key words: Lanzhou-Xining urban agglomeration, quality city, spatiotemporal variation, influencing factors
