The authors conducted a preliminary study on data acquisition scope and established an index system with eight main and 15 secondary indicators. The authors determined the weight of each indicator by consulting experts, residents and tourists and using an information entropy-based weight allocation method. The authors then conducted an empirical study of the Dongmenkou area in Yiyang City. The results show that the street space in Dongmenkou district has issues with inappropriate street width, inadequate street greening, poor night-time safety, and uneven facility distribution.
