目的 大运河的天津段是其重要组成部分，拥有着丰富的运河文化遗产。利用数字化技术，通过构建“线上+线下”交互一体化的天津大运河活态博物馆系统，丰富大运河天津段文化遗产的保护与利用形式。方法 运用地理信息系统(GIS)平台对大运河天津段的文化遗产现状与各类文化遗产空间的结构特征进行核密度分析，根据GIS平台的分析结果规划出天津大运河活态博物馆的线下展示空间范围，并对运河文化遗产分布情况进行博物馆式的各主题展区与游览路线的规划设计。基于可视化、数据库与JPS等数字化技术创新构建大运河活态博物馆数字化平台，并针对数字化平台功能模块与数字导览系统的构建方法，分别进行阐释。结论 构建天津大运河活态博物馆系统，不仅能够丰富大运河天津段的文化遗产保护与利用形式，还可以为大运河国家文化公园的导览系统设计提供参考范式。

The Tianjin Section of the Grand Canal holds a crucial role and boasts a vibrant canal culture heritage. The work aims to employ digital technology to establish a living museum system with "online + offline" interaction capability for the Grand Canal, to enhance the application and preservation of the cultural heritage of the Tianjin Section. The kernel density analysis was conducted by Geographic Information System (GIS) to investigate the current state of the Tianjin Section and the spatial structure characteristics of different cultural heritages. According to the analysis results, the offline exhibition space range of the living museum was planned, and based on the distribution of canal cultural heritage, the various themed exhibition areas in the form of museum and the tour route were planned and designed. Based on visualization technology, databases, and digital technology innovations such as JPS, a digital platform was constructed for the Grand Canal Living Museum, and the construction methods of digital platform modules and digital navigation systems were explained respectively. Building the Tianjin Grand Canal Living Museum system can not only enrich the ways of cultural heritage protection and utilization in Tianjin Section of the Grand Canal but also provide a practical reference for designing the navigation system of the Grand Canal National Cultural Park.
