The effective protection and utilization of historical and cultural heritage in urban and rural areas are increasingly gaining public attention. Constructing a continuous and complete heritage spatial network is an important means for achieving holistic protection and utilization of heritage, and it is also a crucial approach to enhancing the overall connectivity of regional culture. How to construct a cultural heritage corridor is of great significance to the comprehensive protection of cultural heritage in historic urban areas. This study takes the cultural heritage of Tianjin’s historical urban areas as an example, uses the Minimum Cumulative Resistance (MCR) and Gravity Model (GM) to construct a cultural heritage corridor, and evaluates its suitability. This research enriches the theory of heritage conservation, aims to enhance the connectivity and integrity of cultural heritage, and provides a new perspective for the integrated development of regional culture and tourism in the process of activation and utilization.
