Under the background that socialism with Chinese characteristics has entered a new era，the protection and development of the ecological cultural resources of the canal is an important content for the construction of the Grand Canal cultural belt，an organic part of cultural powerful nation strategy，and an important way of international cultural communication，which is of great value to the prosperity of China’s social economy and culture. At present，there are problems in the communication of canal ecological culture：the subject of communication is single，the form and content are not profound and fresh，the means of communication are conservative，and the social attention is insufficient. In this regard，we can improve the communication of the canal ecological culture and explore the global strategic significance of the Grand Canal by improving the top-level design and policy framework，promoting the innovation of form and content，taking advantage of new media and paying attention to the pertinence of communication.
