Abstract: Taking Fuzhou City as the research area, the coupling coordination evaluation index system between new urbanization and ecological environment in Fuzhou City was constructed, and the development degree and coupling coordination of new urbanization and ecological environment in Fuzhou City from 2010 to 2021 were analyzed. The results showed that the new urbanization and ecological environment development level was on the rise overall in Fuzhou City from 2010 to 2021, and its coupling coordination degree was increased from 0.259 6 to 0.654 1 at this stage. The level of coupling coordinated development of new urbanization and ecological environment had also changed from moderate imbalance to moderate coordination, with the degree of coupling coordination increasing year by year, and the overall performance was the lag type of urbanization. Therefore, it was proposed to correctly understand the dynamic coupling relationship between urbanization and ecological environment, adopt the urbanization development strategies suitable for Fuzhou City combined with the development status of Fuzhou City, at the same time take into account the development speed and development quality, and unswervingly take the road of green development, to ensure the coordinated development of urbanization and ecological environment.

Key words: new urbanization, ecological environment, coupling coordination, Fuzhou City
