Abstract: In order to reveal the spatial pattern of economic relations of city tourism and put forward the construction of tourism urban agglomeration in West River economic belt of Guangxi, the West River economic belt of Guangxi is taken as the research subject in this paper and the rectified tourism economic relation modelis used to examine and analyze the economic tourism linkages and the spatial structure of seven central cities in Guangxi in 2015. It is concluded that taking the tie intensity of tourism economy as a standard, the most intense tie with tourism economy in central cities along West River economic belt of Guangxi is characterized by the spatial interconnection, especially the Nanning and Liuzhou, which almost enable them to enjoy a status of “dual core of tourism” in the spatial structure. Spatial interconnection in the intensive region is mainly centered upon districts, such as Nanning, Liuzhou, Guigang and Laibin. Influenced by the radiation intensity in the higher-level tourism economy and the capacity of self-acceptancethe economic ties in tourism of the central cities with the core cities, and those adjacent to the central cities are more frequent, due to their own weak radiation of tourism economy in the surrounding central cities together with the decline of the accessibility, the intensity of economic ties in tourism between tertiary central cities and the central cities is on the fall by gradual. According to the above comprehensive analysis, it is pointed out that all cities should make use of their own advantages to form complementary advantages with the core ones, to forge three tourism urban agglomerations like “Nanning-Guigang-Liuzhou” and “Nanning-Baise-Chongzuo” led by Nanning and “Liuzhou-Laibin-Guigang” led by Liuzhou, and to form mutual compensation, mutual coordination of regional tourism development plate.
