Abstract: Based on the spatial distribution and spatial interaction of tourism industry economic activities, the basic development elements of tourism industry are regulated, and then the optimal industrial element allocation plan is found to release the potential of regional tourism economic development. According to central place theory, Gunn’s theory of tourist destination zone and the theory of tourism industry elements spatial interaction, collect data related to tourism industry development in Dalian, and extract tourism nodes and tourism channels based on the transportation network data set by using GIS network analysis method, construct tourist areas at all levels and optimize the spatial organization of the tourism industry. The results show that:5 first-level tourism nodes, 12 second-level tourism nodes, 10 first-level tourism channels and 12 second-level tourism channels are optimized, on this basis, 5 first-level tourism areas,17 second-level tourism areas and a total of 22 domains are built, the organic combination of tourism nodes, tourism channels and tourism areas forms the spatial organization network of Dalian's tourism industry, recasting Dalian's tourism development axis, expanding the space for tourism development, optimizing tourism industry spatial pattern, and realizing efficient use of industrial elements in warm and cold tourism activities zone. Expand rural tourism development space and promote the transformation, upgrading and high-quality development of rural tourism.
