Research on the Space Optimization of University Campus Public Service Facilities Based on the Concept of Living Circle：a Case Study of Wuhan University

The "15-minute life circle" has become the reference concept for the allocation of public service facilities in most communities， but most of them focus on the research of urban residents. The large number of college students on university campuses also needs to be paid attention to， especially the uneven distribution of facilities and travel difficulties in some large-scale comprehensive university campuses. Under the guidance of the life circle theory， the paper took Wuhan University as an example， firstly divided the basic life circle and extended life circle of the university campus according to the questionnaires combined with the attenuation function. Secondly， ArcGIS was used to analyze the accessibility of objective facilities and the satisfaction of facilities combined with the questionnaires， and the two were compared and analyzed through the comprehensive convenience indexes. Finally， based on these indicators， the existing problems were summarized and optimization strategies were proposed for the spatial layout of existing public service facilities： it was suggested to add shopping and entertainment facilities at the junction of Lakeside living circle and Maple Garden living circle， optimize the layout of dining facilities and supplement the medical facilities of Lakeside living circle， and improve the functional layout of campus life by shortening service distance and improving facility quality.
