黄河下游影响区城镇化-生态和谐机制与耦合协调发展分析

本文通过和谐度与耦合度双重评价，利用和谐度模型、耦合协调度模型及协调发展度模型，对黄河下游影响区2005—2018年城镇化与生态环境耦合水平在时空上的变化规律进行研究。结果表明：①研究区域耦合水平在整体上呈现先下降后升高的变化规律，耦合关系在阶段上属于由磨合向高水平耦合过渡的阶段，城镇化发展多滞后于生态环境。②黄河下游影响区形成了以郑州和济南为核心的高耦合程度聚集区，且表现出先聚集后辐射扩散的空间聚集与溢出效应。③当前研究区城镇经济发展对耦合水平的贡献较大，现阶段城镇发展对生态环境的综合影响无明显负向倾向。

Analysis on the harmonious mechanism and coupling coordinated development of urbanization and ecology in the influenced area of the low Yellow River

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.
