Abstract: Taking Shandong province as the research area, the comprehensive evaluation index system of tourism, urbanization and ecological environment in Shandong province was constructed, and the comprehensive development index, coupling degree and coupling coordination degree of tourism development, urbanization level and ecological environment quality in Shandong province from 2009 to 2019 were calculated by using range standardization, entropy method and coupling coordination degree. The results showed that, from 2009 to 2019, the comprehensive development level of tourism, urbanization and ecological environment in Shandong province continued to rise; The level of urbanization was higher than that of tourism and ecological environment; The coupling degree and coordination degree of the system were relatively low, showing a state of imbalance. In the future, while vigorously improving the level of urbanization and developing tourism, Shandong province should pay more attention to the protection of ecological environment and realize the coordinated development of tourism, urbanization and ecological environment.

Key words: tourism, urbanization, ecological environment, coupling coordination, entropy method, Shandong province
