Abstract: In recent years,the renewal and construction of urban public spaces in Xiahe County,Gannan Prefecture,Gansu Province,China has accelerated with the rapid development of urbanization and tourism. Meanwhile,it has also brought about a series of problems such as the spiritual transformation of these places and reduction in recognition. Based on a social investigation and road network topology modeling of the research area,this study analyzes the spatial quality and vitality of the research area by using the fuzzy comprehensive evaluation method,spatial syntax method,and nuclear density analysis. First,the perceived object is divided into passengers and local residents and the spatial quality of public places is evaluated in the research area. Then,the spatial accessibility of these places is measured by spatial syntax and the intrinsic relationship between the activity and accessibility of the place is explored by evaluating the cross-sectional road traffic. Finally,in terms of the public place unit,place group,and place system,specific construction strategies are proposed at the micro-,medium and macro-scales,respectively. The research shows that there are obvious differences between local residents and tourists in spatial cognition due to the differences in cultural identity and behavior. The spatial accessibility analysis shows that the commercial and cultural places of Plexla and the religious and cultural places of Labu have high spatial recognition and good connectivity,which belong to high-accessibility spaces. The study of staying spaces shows that there are some differences between staying spaces for residents and tourists. On this basis,the place units,commercial and cultural places,and five other public place groups are proposed as specific construction strategies. Further,it is recommended that the construction of a place system should be from the perspectives of constructing systematic places by adhering to the principle of multiple groups and multiple strategies,constructing multisubject places by creating highly accessible places,and constructing group and place systems of hotspot units in order to create high-quality,high-vitality place systems. Meanwhile,it is expected to provide a set of public space evaluation methods and construction strategies for establishing public spaces in tourist-oriented cities.
