Abstract: Under the domestic cultural heritage protection system, the protection of ancient routes as cultural relics has not been fully coordinated with the international concept of cutural route conservation. It puts us in a dilemma that the domestic cultural relics protection system is unable to link up with the international conservation vision. This paper takes the cultural line as the object, and clarifies the framework of the traffic heritage as the domestic heritage protection system by sorting out its space-time scope and value perception. It takes the Micang Road (Bazhong Section) as the object, which is applying to get listed as an intangible cultural heritage, and needs to be docked with specific protection tasks. It aims to clarify the framework for conjoining the international conservation perspective and domestic conservation system on heritage routes, which may provide references for the researches and protection of related cultural routes heritage in China.
