Old community districts grapple with issues such as antiquated infrastructure and functional designs that fail to meet contemporary needs. These limitations lead to diminished disaster resistance and a reduced quality of life for inhabitants. Public spaces within these antiquated districts can function as sanctuaries during calamities, enhancing the community’s disaster response efficacy and expediting post-disaster recovery, which is vital for effective disaster management. Nevertheless, the disaster-resilience attributes of public spaces in these old districts have not been sufficiently researched. This study focused on three representative old communities in Beijing, analyzing and contrasting their disaster resilience attributes and various community types. Utilizing the Analytic Hierarchy Process, a hierarchical structural model was formulated, examining the public spatial structure, function, transportation, and ecology. A comprehensive analysis was then conducted to identify the resilience characteristics that public spaces in old communities should possess. The findings indicated that the prioritization of the four criteria—ecological space, transit space, spatial function, and spatial structure—in the development of disaster-resilient public spaces in communities increases progressively. The renovation to increase the disaster-resilience of old communities should concentrate on optimizing the spatial structure layout of the community, enhancing the integrity, openness, and coherence of public spaces; imbuing public spaces with versatile and multifaceted functions, and establishing hierarchical distribution systems; ensuring transit spaces cater to both everyday use and disaster exigencies, maintaining unimpeded traffic flow under all conditions; and creating multi-tiered ecological spaces to bolster resilience during disasters while enhancing daily aesthetics. This research enriches the strategies for the disaster-resilient renovation of public spaces in old communities, offering precise and scientific references to improve community disaster resilience and emergency response capabilities.

With the rapid development of urbanization and tourism in China, increasing attention has been paid to the protection and utilization of historical and cultural heritage, while tourists’ demands for travel experiences have gradually shifted towards in-depth cultural perception. This paper selects Beijing Fayuan Temple Historic and Cultural District as the research case, and adopts methods such as the LDA (Latent Dirichlet Allocation) topic model, collection and analysis of online text data, and field research to explore the current situation of pedestrian space in Fayuan Temple District and its optimization strategies from the perspective of tourists’ perception. The study found that the dimensions of tourists’ perception of the pedestrian space in Fayuan Temple District mainly include six aspects: historical buildings and relics, tour modes and transportation, natural landscapes and environment, historical figures and culture, residents’ life and activities, and tourists’ experiences and visits. By integrating online text data, questionnaire surveys, and on-site behavioral observations, the study constructed a “physical environment-cultural experience-behavioral network” three-dimensional IPA (Importance–Possession Analysis) evaluation model, and analyzed and evaluated the high-frequency perception elements in tourists’ spontaneous evaluations. Based on the current situation evaluation of the pedestrian space in Fayuan Temple District, this paper puts forward optimization strategies for the perception of pedestrian space from the aspects of block space, transportation usage, landscape ecology, digital technology, and cultural symbol translation. It aims to promote the high-quality development of historical blocks by improving and optimizing the pedestrian space, and achieve the dual goals of cultural inheritance and utilization of tourism resources.
