Abstract: Base on the analysis of the influencing population, space flow, and the shortest path of urban tourism, the concept of collaboration degree of urban tourism was explicitly proposed, the collaboration degree measure model of urban tourism was creatively constructed. Taking 36 prefecture level cities of Yangtze river economic belt as the research object, spatial-temporal structures and development patterns of urban tourism coordinate development of Yangtze river economic belt in 1990, 1999, 2008, and 2018 were explored, with the method of entropy, principal component analysis and network analysis. The results showed that, the development patterns of urban tourism could be divided into collaboration pattern, integration pattern, basic pattern, and unorganized pattern according to the collaboration degree. The collaborative development patterns of urban tourism was transforming from unorganized pattern to collaboration pattern between 1990 to 2018, the collaborative development of urban tourism will be the represent the general trend of the future. Development of urban tourism changed from the original pursuit of economic coordination to the pursuit of economic, social, cultural, environmental multiple collaborative developments, which indicated the spatial-temporal structure evolution of urban tourism followed the basic law of urban tourism development in China.

Key words: collaboration degree of urban tourism, spatial-temporal structure, Yangtze river economic belt
