With the rapid economic and social development, the accelerating modernization and urbanization, and also drastic changes of traffi c environment have contributed to the endangered situation of ancient Sichuan salt road cultural heritage. In face of such problems as lack of coordinated protection mechanism, destructive development, backward protection of cultural relics, and inheritance risks of intangible heritage, cultural heritages along the ancient Sichuan salt road should be protected by establishing a protection mechanism, organizing the coordinated actions of local areas along the road, investigating and rescuing cultural heritage in time, and enhancing the cooperative research. In view of the complicate and long-term nature of protecting linear cultural heritage, successful experience of domestic and foreign cultural route heritage management can be learned, salt transportation cultural heritage protection, tourism planning and development of ancient Sichuan salt road should be considered, protection of the ancient salt road should be combined with economic, social and cultural development of regions along the road, so as to explore an effective mode for the protection, development and management of large-scale linear cultural heritages consisting of both land and water routes.展开更多
