在交通强国与文化强国战略背景下，通过此项研究拓展文旅融合发展内容，为交通遗产的活化利用提供理论支撑与案例参考。运用文献综述法、归纳总结法和个案研究法，形成交通遗产与文旅融合发展的“理论—路径—实践”系统分析框架，取得以下研究成果。①界定了交通遗产概念内涵：明确交通遗产的概念，提炼出交通遗产具有空间分布的跨区域性、影响力的圈层扩散性、要素的动态多样性、历史跨度的深厚性、主体功能的历史变迁性、多维价值的延续性等六大特征，构建了多维度交通遗产的分类体系与判定标准。②搭建了四维融合框架：基于旅游系统理论，构建包含游客主体需求、目的地供给、内外支持与中介等4个层面要素的交通遗产与文旅融合系统。③提出了四大实践路径：基于“文化廊道”理论对整体性与延续性的要求，立足旅游系统理论，提出深化互动体验、推动业态融合、强化制度保障、构建传播矩阵等四大实践路径。④通过典型案例验证交通遗产与文旅融合实践：通过对大运河、滇缅公路、滇越铁路的案例剖析，验证了上述理论与路径的适用性。研究成果可为平衡遗产保护与利用、推动文化传承与经济发展提供系统性思路与实践参考。

Under the strategic background of building China into a country with strong transportation network and a thriving socialist culture, the aim of the research is to enrich the content of cultural-tourism integration, and provide theoretical support and case references for the revitalization and utilization of transportation heritage. By using literature review, induction and summary, and case study methods, a systematic analysis framework of "theory, path, practice" for the integrated development of transportation heritage and cultural tourism has been formed, and the following research results have been achieved: ①Defined the connotation of the concept of transportation heritage: clarified the concept of transportation, and extracted six key characteristics of transportation heritage, including its cross-regional spatial distribution, the concentric diffusion of its influence, the dynamic diversity of its elements, the profound historical span, the historical evolution of its primary functions, and the continuity of its multidimensional value. A multi-dimensional classification system and criteria for idendifying transportation heritage have been established; ②Established a four-dimensional integration framework: based on the theory of tourism systems, a transportation heritage and cultural tourism integration system was built, which includes four levels of elements such as tourist demand, destination supply, internal and external support, and intermediaries; ③Four major practical paths have been proposed: based on the "cultural corridor" theory′s emphasis on integrity and continuity, and utilizing the tourism system theory as a foundation, four practical paths have been proposed including deepening interactive experience, promoting business forms integration, strengthening institutional guarantees, and establishing a communication matrix; ④The integration practice has been validated through case analysis of the Grand Canal, Yunnan-Burma Road, and Yunnan-Vietnam Railway, demonstrating the applicability of the above theories and paths. The research outcomes are expected to provide systematic ideas and practical references for balancing heritage conservation and utilization, as well as promoting cultural inheritance and economic development.
