Currently, historical areas in China are facing issues of color authenticity and excessive commercialization. Colors, as an important element of historical areas, reflect their history and culture. However, there are some flaws in the existing research methods, so a more scientific and systematic method is needed to obtain accurate and objective color visualization results to promote the sustainable development of historical areas. In order to explore the methods and applications of visualizing the environmental color patterns of historical areas, Shiquan Street in Suzhou, China, was taken as the research object; ArcGIS 10.5 was used to obtain the street-view photo samples; Matlab was used to summarize the architectural colors of the historical areas; and K-means clustering was used to generate the central color card of the historical areas, thus completing the color visualization of the historical areas, followed by further searching for the color patterns and central colors, so as to explore the strategies for sustainable development of historical areas. The various quantified color models of historical areas can explore the regional uniqueness and color locality of historical areas, which avoids problems such as homogenization of block colors, unclear styles and features, and an excessive proportion of commercial colors caused by poor color guidance and control in the design related to historical areas, providing approaches to the research on the harmonious unity of environmental colors and features related to historical areas. A color-based research method has been proposed to protect and maintain the original appearance of historical areas. The application of this method provides a new perspective and possibility for the protection of historical areas, allowing these areas to achieve historical sustainability while maintaining their historical characteristics and values.

With the transition to a knowledge economy becoming an important aim, this qualitative study examines rural communities (Yongning and Xunpu) near heritage sites in Quanzhou, China. “Pu Jing” and exhibition space are connected with the inheritance and creation of intangible cultural heritage in order to form a knowledge economy with unique local characteristics around these sites. Beliefs and customs that reconstruct social values are integrated with heritage conservation. Economic competition and social capital restructuring strengthen social identification and benefit building community resilience. Combining with the “Local Tourism Alliance” activities organized by local organizations is important when developing innovative education and tourism activities. The innovation-oriented rural revitalization strategy has promoted community resilience in rural areas around the heritage sites, enhanced local area values, and encouraged social and economic efficiency.

Within UNESCO’s framework for sustainable heritage, this study examines how community engagement shapes the conservation of religious architectural heritage and the continuity of cultural landscapes. Using Sanliqiao Catholic Church in Wuxi, China, as a case study, it explores how heritage value is produced through the interaction of everyday practices, place identity, and participation in governance. Drawing on 19 interviews, field observations, archival materials, historical images, and 216 online comments, the findings reveal how everyday spatial practices sustain the cultural landscape. These practices generate differentiated place identities among believers, residents, and commercial stakeholders. Such identity differences, in turn, influence uneven participation in heritage governance and shape how cultural value is experienced and distributed. Cultural landscape reproduction thus emerges as a dynamic process linking everyday practice, identity formation, and participatory governance structures. The study underscores the critical role of inclusive participation in heritage governance and contributes to broader international debates on socially sustainable heritage management, with implications for similar religious and urban heritage sites beyond the Chinese context.
