Global Research Trends and Future Directions in Urban Historical Heritage Area Conservation and Development: A 25-Year Bibliometric Analysis

Urban historical heritage areas serve as vital repositories of urban culture and history, playing a crucial role in cultural inheritance and the promotion of urban development. The protection and development of these heritage areas are essential for preserving the cultural characteristics and architectural styles of cities. Despite the growing body of research, a comprehensive review of the dynamic evolution, research frontiers, and future trajectories in this field remains absent. To bridge this gap, this study draws on the Web of Science Core Collection database, selecting 828 papers published between 2000 and 2024 that focus on urban historical heritage conservation and development. By employing Python programming and network analysis tools, this study conducted a systematic analysis of research structures and trends over the past 25 years. The results indicate that countries such as China and Italy, along with their respective research institutions, are at the forefront of global research in this area. Furthermore, this study identified research hotspots, including historic districts, sustainable urban development, urban regeneration, risk assessment, 3D modeling, digital documentation, and cultural tourism. This research not only discusses the challenges faced in the field but also explores future development trends, providing new theoretical perspectives and practical guidance for subsequent studies.
