摘要:

城市空间与建成环境的协同发展是实现城市可持续发展的重要途径。以河谷型城市兰州为例,基于多源数据构建社区建成环境质量评价指标体系,研究其城市空间结构及影响因素。结果表明:(1) 建成环境视角下,兰州市城市空间呈现东西向轴带状“核心-边缘”结构,典型特征为带状主导下的“多中心+扇形扩展区”。(2) 利用回归分析可知,土地价格、平均高程、社区到区行政中心的距离、社区到车站的距离对城市空间结构的形成发挥着主要作用,社区到地铁站的距离、社区道路网密度、用地类型、公共空间、人口数量起次要作用。(3) 土地价格和用地类型对城市空间结构的作用力持续增强。研究结果对优化河谷型城市空间和促进城市高质量发展具有一定的理论和现实意义。

Abstract:

The synergistic development of urban space and the built environment is essential for achieving sustainable urban development. This study examines Lanzhou, a river valley city, by constructing a community built environment quality evaluation index system using multi-source data to analyze its urban spatial structure and influencing factors. Key findings include: (1) From the perspective of the built environment, Lanzhou’s urban space exhibits an east-west axial, belt-like “core-periphery” structure, characterized by a spatial distribution pattern combining multiple centers with a fan-shaped expansion area dominated by the axial belt. (2) Regression analysis indicates that land price, mean elevation, distance from communities to the district administrative center, and distance to transportation stations significantly influence the urban spatial structure, while distance to subway stations, community road network density, land use type, public space availability, and population size have secondary impacts. (3) The influence of land price and land use type on the urban spatial structure has steadily increased. These findings offer theoretical and practical insights for optimizing urban spatial configurations in river valley cities and promoting high-quality urban development.
