Ancient bridge heritage is an indispensable part of cultural heritage, but many are at risk of demolition due to urban and rural development and natural deterioration. Consequently, there is an urgent need for their protection and restoration. This study aims to explore a more systematic approach to the protection of ancient bridge heritage and provide a theoretical basis and methodological support for related practices. Drawing on the methods and perspectives of urban historical landscape, this study approaches this from the two perspectives of historical layering and environmental integrity, and constructs a spatiotemporal model of ancient bridge heritage that integrates the two. On this basis, a three-dimensional cognitive system covering the original value, social value, and cultural value is established, forming a systematic analysis framework. The research employed a combination of qualitative and quantitative methods, including literature analysis and historical map analysis, remote sensing image interpretation and GIS spatial analysis, as well as field investigations and cross-validation with multiple data sources. Taking Beiyang Bridge in Wuhan as a case study, this study systematically reveals its multi-dimensional value characteristics, including the historical layering of the ancient bridge itself, the overall connection with the surrounding environment, and the social and cultural significance it carries. Based on the current status of Beiyang Bridge, this study proposes targeted protection and utilization suggestions from three aspects: the protection of the intrinsic value of the ancient bridge, the protection of environmental integrity, and the continuation of social and cultural value, providing a reference for the research on the value exploration, protection, and sustainable utilization of ancient bridge heritage.
