Abstract: With the aim of shortening the length of ineffective tourism routes and reducing carbon emissions, this study proposes a new green tourism route planning method based on sustainable development theory. First, based on the sustainable development theory, the information chain of tourism landscape elements is established to form an orderly organisational form of landscape factors. Then, the knowledge graph of tourist attractions is constructed. After crawling historical travel notes, the database of tourist attractions is established, and LDA is used to cluster tourist attractions. Finally, a route planning model is established with the optimisation goal of minimising the length of daily tourist routes and the carbon emissions generated. Experimental results show that, while visiting all ten scenic spots, the total length of the route planned by this method is 97.2 m, and the carbon emissions generated are only 3,992 kg, indicating that this method meets the requirements of sustainable development.

Keywords: sustainable development; green tourism; tourism route planning; landscape factors; knowledge graph; latent Dirichlet allocation; LDA; route length; carbon emissions.
