Abstract: The evaluation index system of coupling and coordinated development of tourism economy and ecological environment is
constructed, and the coupling and coordination degree of tourism economy and ecological environment in Guangxi Two Districts and One Belt from 2010 to 2021 is calculated, and then its spatial and temporal evolution characteristics are explored, and the gray correlation degree model is used to explore the driving factors of coupling and coordination degree. The results show that the coupling coordination degree of the three regions in the study period shows a good upward trend on the whole, and the coupling coordination level is improved from the verge of imbalance to the primary coordination; The differences in the Xijiang Economic Belt and the Beibu Gulf Economic Zone are significantly higher than those in the resource-rich areas of western Guangxi; The regional differences between the Beibu Gulf Economic Zone and the Xijiang Economic Belt are relatively large; The hypervariable density has become the dominant factor affecting the source of the difference in the coupling coordination degree of Guangxi; And the factors affecting the degree of coupling and coordination are in the order of urban development scale, industrial structure, population size, transportation conditions, government regulation and economic development level according to the intensity of action.

Key words: tourism economy, ecological environment, coupling coordination degree, interval difference, gray correlation degree
