Construction of Cultural Heritage Tourism Corridor for the Dissemination of Historical Culture: A Case Study of Typical Mountainous Multi-Ethnic Area in China

The conservation and utilization of cultural heritage resources play a crucial role in the sustainable development of regional tourism in mountainous multi-ethnic areas. Nevertheless, these heritage resources tend to be numerous and geographically dispersed, poorly accessible, and difficult to preserve and utilize, which makes utilizing them holistically at a regional level challenging. Furthermore, each cultural heritage has a specific capacity for cultural dissemination, and establishing the links between heritage sites can enhance the overall cultural influence of a region and promote the development of regional tourism. Consequently, this study aims to promote the conservation and utilization of cultural heritage by constructing a cultural landscape tourism corridor network in the region. A potential cultural landscape tourism corridor network was first constructed based on the least-cost path analysis. Then, the layout and hierarchy of the potential network were optimized based on the existing traffic layout in the area. Finally, for mountainous multi-ethnic areas with poor access to transportation, the tourism corridor network may support the holistic conservation and use of the region's cultural heritage and the development of regional cultural tourism.
