Abstract: 【Objective/Meaning】 In the development process of rapid urbanization,there were a series of ecological and environmental problems,such as serious waste of water resources,degradation of air quality and land degradation,etc. By exploring how to take the protection of ecological environment into consideration in the process of urbanization,it would provide theoretical and methodological support for promoting the sustainable development of cities and the society. 【Methods/Procedures】 The coupling coordination degree model and geographic detectors were used to analyze the coupling coordination degree and influencing factors of the urbanization and ecological environment in Fujian Province from 2009 to 2017.【Results/Conclusions】The coupling coordination between the urbanization and ecological environment in Fujian Province from 2009 to 2017 showed an upward trend,and the coordination level has developed to the moderate coordination; The degree of coupling coordination between the urbanization and ecological environment in each city of Fujian continued to increase,and almost all of them were barely coordinated and above,while Fuzhou,Xiamen and Quanzhou have reached high quality and sound coordination; The spatial differentiation was mainly manifested in the high coordination of southeast coastal areas and the low coordination of northwest inland areas; And the main influencing factors of the spatial differentiation included R&D expenditures,the proportion of the added value of secondary and tertiary industries in GDP,per capita financial budget income,etc.
