Abstract: Taking Karamay City, Xinjiang as the research object, the urbanization and ecological environment indicator system was consturcted to study, the comprehensive development level and coupling coordination degree relationship between urbanization and ecological environment in Karamay City from 2008 to 2019 by using the entropy method and coupling coordination degree model. The results showed that the comprehensive development level of urbanization and ecological environment in Karamay City was on the rise, and the development level of the two systems had a small gap; the coupling coordination degree increased from 0.471 0 in 2008 to 0.881 7 in 2019 during the study period, with a relatively high overall level; the coupling and coordinated development of urbanization and ecological environment could be divided into five types： the near imbalance type, the reluctant coupling and coordination type, the primary coupling and coordination type, the intermediate coupling and coordination type, and the good coupling and coordination type. The overall development trend was on the rise. Therefore, some suggestions were put forward, such as correctly understaning the dynamic coupling relationship between urbanization and ecological environment, adoping appropriate urbanization development strategies, paing attention to the speed of development while ensuring the quality of development, taking the road of green development, and taking the road of coordinated development of urbanization and ecological environment.

Key words: urbanization, ecological environment, entropy method, coupling coordination degree, Xinjiang
