Research on the Coupling Relationship Between Park and Metro Station Space in Qingdao

As indispensable elements of public space in the city, metro stations and parks have the dual characteristics of “node” and “place”. Based on the “node–place” theoretical framework, the spatial evaluation and detailed classification of Qingdao metro station is carried out by integrating ArcGIS technology and diversified data sources. On this basis, an innovative metro station spatial coupling evaluation model is constructed, which takes into account the station carrying capacity, park accessibility, land use degree, and other factors, while evaluating the economic and environmental benefits. This study deeply explores the complex coupling relationship between the surrounding metro stations and park space in Qingdao. According to the results of the evaluation model, corresponding strategies for different types of station space are proposed. By taking measures, such as focusing on fine development strategies, stimulating the vitality of stations and implementing guided renewal, and enhancing the mutual suitability of rail transit and surrounding park space, the great potential of combining green ecology with urban space optimization is demonstrated.
