Analysis on the Coupling Relationship between Smoke-Free City Community Public Service Function and Street Space

Objectives: In this study, with Gulou District, Xuzhou City, Jiangsu Province in eastern Chinataken as the research object, the coupling coordination model between the two subsystems, namely smoke-free city communitypublic servicefunction and street space vitality, was constructed based on the principle of synergy theory. Next, the measurement system of street space form in the research area was established with the aid of urban basic information data provided by the open data platform and the GIS technology. Furthermore, the related system was evaluated by the entropy method and the spatial syntax, and the results of multi-dimensional systematic evaluation indexes were visualizedby introducing the grid method. Finally, the internal coupling coordination relationship between smoke-free city communitypublicservice function and street space vitality was revealed to assistant smoke-freepublic service space design and optimisation and guide fine smoke-freecity planning practice. The following results were obtained. Population density and spatial integration are important evaluation indexes for measuring the coupling between public service function and street space vitality. Therefore, appropriate residential density and street traffic vitality are the key to promoting the development of community public service space. In view of this, this study can provide a quantitative basis for the construction of smoke-free public environment in healthy cities.
