Abstract: Through the double evaluation of harmony degree and coupling degree, and using the harmony degree model, coupling coordination degree model and coordinated development degree model, this paper studies the temporal and spatial change law of the coupling level between urbanization and ecological environment in the influenced area of the low Yellow River from 2005 to 2018. The results show that:①On the whole, the regional coupling level shows the change law of falling first and then increasing. The coupling relationship belongs to the transition stage from running-in to high-level coupling, and the development of urbanization lags behind the ecological environment. ②The influenced area of the low reaches of the Yellow River forms a highly coupled aggregation area with Zhengzhou and Jinan as the core, and shows the spatial aggregation and spillover effect of first accumulation and then radiation diffusion.③At present, the urban economic development in the study area makes a great contribution to the coupling level, and the comprehensive impact of urban development on the ecological environment has no obvious negative tendency at the present stage.

Key words: urbanization-ecology, harmony degree, coupling coordination degree, coordinated development degree, the influenced area of the low Yellow River
