Since 2019, the application of digital technology (DT) in cultural heritage conservation (CHC) has transitioned through various phases: from structural prediction and maintenance, to parametric modeling workflows, to collaborative heritage management and assessment, and finally to the integration of technologies and new applications across interdisciplinary fields. What development trends can be observed in the application of DT to CHC in recent years? What difficulties and challenges does it face? Recent studies have primarily focused on technology-driven approaches, but there is a lack of systematic reviews on the current state of research, application progress, and development trends. This paper addresses these research gaps by utilizing bibliometric techniques, including trend analysis through yearly publication and citation line graphs, mapping with visual tools, subject categorization and distribution statistics, co-authorship and keyword-based biclustering, keyword frequency analysis, thematic co-occurrence networks, and content analysis of key articles. A scientometric analysis, conducted using COOC 6.725 and VOS Viewer, applied a Boolean search strategy to filter 345 articles from the Web of Science Core Collection, covering the period from 2019 to 2024. The document types analyzed include articles, reviews, and conference proceedings, all in the English language. The objectives of this paper are to: (1) summarize progressive research trends; (2) analyze interdisciplinary integration; (3) map out author collaboration networks; (4) explore the application potential of DT; (5) reveal cutting-edge topics; and (6) investigate focal issues. Lastly, this paper discusses ethical and social responsibility concerns in DT applications, particularly the challenges related to technology accessibility and data protection. With the rapid development of AI and DT, DT is expected to demonstrate even greater potential and value in CHC.

Given the complex interplay between economic and cultural–historical factors, this paper explores scene perception and its mechanism in individual and collective cognition of historical commercial streets. Based on a perception model constructed from scene theory, the study utilizes user scene experience feedback from Beijing Road, a commercial pedestrian street in Guangzhou. It conducts a systematic assessment using hierarchical analysis (AHP) across three dimensions: authenticity, theatricality, and legitimacy. The findings reveal the following: (1) according to visitors, traditional cuisine, cultural and creative arts, and Lingnan’s intangible cultural heritage received low ratings; (2) historical relics and traditional cuisine are dominant factors, highlighting public attention to cultural heritage, but the role of historical–cultural characteristics and festival activities is relatively marginalized; (3) cultural–historical relics and traditional cuisine are the leading factors that contribute to an authentic experience, while historical context and festival activities constitute secondary factors; (4) cultural landscapes and arts are central to theatrical experiences, with modern visual elements playing a lesser role; (5) diversified commercial formats and public services are the core factors influencing legitimacy experience, reflecting the role of market diversity and policy orientation in building consumer trust. The design of historical and cultural streets should prioritize the preferences of those experiencing them to promote cultural identity and historical continuity. Additionally, the synergy between commercial diversity and policy orientation should be strategically emphasized to form a business ecosystem supporting sustainable development. Future commercial street renewals should focus on the key role of visual narrative in shaping brand culture. This paper offers insights into the dynamic process of constructing scene experience from perspectives of spatial materialization and emotional empowerment to cultural identity, providing references for strategies in historical place renewal.

The study of clan paintings reveals a shift in perspective from art aesthetics to cultural connotations to cultural identity, yet literature seldom discusses the relationship between art and kinship culture. Taking the murals of ancestral hall architecture in Guangzhou as an example, this paper utilizes text mining to identify factors influencing its decorative art. It reveals the traditional rites' artistic expression through dimensions of characters' demeanor and the transmission of content values, offering a fresh perspective for heritage value research. Findings: (1) themes and implications are mostly oriented towards positive value transmission, transitioning from idealistic layman life to the realism of lower-class existence, emphasizing humanization; (2) the extroverted portrayal of characters contrasts with the dignified, restrained etiquette of traditional rites, with some characters' portrayal and facial expressions exuding approachability; (3) murals conveying positive emotions are mostly related to longevity, auspiciousness, fortune, and heroic deeds, while those conveying negative emotions mainly involve elderly male figures, reflecting a content bias related to characters; (4) historical allusion murals with complex content reduce the emotional resonance and arousal efficiency of the viewer; (5) incomplete mural content increases negative emotions in perceivers, highlighting the impact of mural preservation on emotional resonance. To delve into the formation of clan painting art, it is essential not only to interpret the diversity of its patterns but also to demonstrate the representation of its social attributes in decorative art. The formation of clan painting decorative art exhibits kinship cultural attributes, epitomizing the essence of traditional ceremonial thought.

Recent research has primarily focused on the genealogical relationship between ancestral temple painting and its spatial carriers, highlighting a shift in perspective from artistry to symbolism to kinship. While some scholars have noted the influence of ritual culture on architectural painting, few have explored its kinship relationship with architectural carriers. By incorporating relational sociology theory, this study chronologically reviews events influencing the formation of ancestral temple ritual culture, constructs a developmental model, and conducts case studies on the ethicality of architectural painting art, thus establishing a relational sociology analysis framework. Findings: (1) Ancestral temple architectural painting exhibits the ethicality and educational value inherent in Confucian concepts; (2) Themes such as immortal life, literati and scholars, and common folk simplicity highlight the spiritual and material kinship of ancestral temple painting. The vocabulary used in titles such as "He (rapprochement-和)", "He (reunification-合)", "wealth (财)", "happiness (乐)", "blessing (福)", and "longevity (寿)" reveals a positive transmission of Confucian values; (3) The five main artistic expressions of ancestral temple painting are metaphor through objects (借物喻意), the personification of events (以人喻事), using the past to illuminate the present (借古喻今), expressing aspirations through objects (托物喻志), and pun-based symbolism (谐音寓意); (4) The decorative elements of ancestral temples correspond to the forms of their painting art, with the former extending the space of the tomb sacrificial system and the latter representing artistic inheritance. The development of ancestral temple architecture has formed dual developmental contexts centered on ritual culture and supplemented by academic dissemination, fluctuating with the status of Confucianism. The relational sociology model shows that the political aspects of ancestral temples form a sub-lineage of their ritual culture, closely linked to reforms in the educational system and transformations in building functions, further influencing architectural form and decorative art.

The formation of decorative patterns on export porcelain has risen to the research dimension of cross-regional culture. The interplay between social elements and the formal evolution of export porcelain bowls from the Qing Dynasty in Guangzhou remains nebulous. This study elucidates these underlying cultural dynamics through the lenses of utility and societal implications, thus addressing how societal components contribute to the molding of tangible cultural heritage. Key findings include: (1) A dominance of the ring-foot design in the bases of Qing Dynasty export bowls; (2) The diameter and height of the Qing Dynasty export bowls show relatively concentrated characteristics, reflecting a systemic production trend and relative consistency in form; (3) Some of the Qing Dynasty bowls exceed the parameter range of typical tableware, reflecting the adaptability and innovation of production mechanisms in responding to special market demands. The morphological evolution of the Qing Dynasty export bowls is a true reflection of the interweaving of multiple factors such as comfort design and aesthetic preferences, while the uniformity in shape is a comprehensive reflection of meeting market demands and advances in production technology. This study extends the research dimension to the interaction between standardized production techniques and socio-cultural demands.
