济南市路网结构句法特征及其对商业布局的影响

The influence of road network morphology on the layout of commercial facilities in Jinan based on spatial syntax

研究城市路网与商业设施布局的关系能促进城市经济发展和资源高效合理配置。文章以济南市中心城区为例,基于空间句法的线段模型、核密度估计法及最邻近距离法从多尺度分析城市路网形态及其与商业功能设施布局的关系。结果表明:中心城区的商业设施呈多核心聚集分布特征,除汽车服务类设施分布在中心城区边缘外,其余类型设施多在主城区形成大面积聚集;中心城区路网分布特征存在空间差异且空间的协同性一般,主城区路网承担主要的整合和承载交通的职责,东、西新城区缺少对城市局部空间的整合与渗透能力;路网形态对商业设施布局的影响存在差异,汽车服务类受影响较小,而美食类对路网形态依赖性大,所有类型的商业设施更倾向于分布在高可达性和整合度的路网附近。

Investigating the relationship between urban road networks and the layout of commercial facilities contributes to urban economy and the efficient allocation of resources..Using the central district of Jinan as a case study,the study analyzes the morphology of the urban road network and its correlation with the distribution of commercial facilities,and employs multiple scales based on the line segment model of spatial syntax,the kernel density estimation and the nearest neighbor distance method.The results reveal that commercial facilities in the central district exhibit a multi-core clustering distribution.While automotive service facilities are situated on the periphery of the central urban area,other types of facilities tend to cluster extensively in the main urban area.There are spatial differences in the distribution characteristics of the road network and the spatial synergy is general.The main urban area s road network predominantly undertakes the responsibilities of integration and traffic bearing,while the new urban areas in the east and west lack the capacity for integrating and penetrating local urban space.There are differences in the impact of road network morphology on the layout of commercial facilities,with automotive services being less influenced and gastronomy being more dependent on road network morphology.All types of commercial facilities tend to be situated near road networks characterized by high accessibility and integration.
