[目的] 探索河南省城市化与生态环境耦合协调状态的空间聚集特征，提出相关的发展建议，为河南省城市可持续发展提供科学的参考。[方法] 通过构建城市化与生态环境评价体系，利用改进的耦合协调度模型，研究2008—2018年河南省城市化与生态环境发展水平及耦合协调度，对河南省17个地级城市耦合协调度进行时空格局分析。[结果] 2008—2018年全省耦合度值都在0.9以上，耦合协调度呈波动上升趋势；多数城市的城市化水平低于生态环境水平，各市城市化与生态环境的耦合协调度等级有基本不协调、基本协调、协调、高级协调；城镇化与生态环境耦合协调存在空间正相关性，有西部和中部耦合协调度高、东南部耦合协调度低的聚类特征。[结论] 河南省整体城镇化进程加快，经济城市化和生态环境压力分别对城市化和生态环境两大系统产生了重要影响。应加强郑州市中心城市的发展，推动河南东南部城市的发展。
[Objective] The spatial agglomeration characteristics of coupling coordination in He'nan Province were explored, and relevant development suggestions were put forward to provide a scientific reference for the sustainable urban development in He'nan Province.[Methods] An urbanization and ecological environment evaluation system and an improved coupling coordination degree model were used to study the level of urbanization and eco-environmental development and coupling coordination in He'nan Province from 2008 to 2018, and to analyze the spatial-temporal pattern of coupling coordination degree for 17 prefecture level cities in He'nan Province.[Results] From 2008 to 2018, the coupling degree values were all above 0.9 and were in the high coupling level. The coupling coordination degree exhibited a fluctuating upward trend. The urbanization level of most cities was lower than the level of ecological environment. The coupling coordination degree of urbanization and ecological environment in each city could be characterized as basically uncoordinated, basic coordination, coordination, or advanced coordination. There was a spatial positive correlation between urbanization and ecological environment coupling coordination, with clustering characteristics of high coupling coordination in the western and central regions and low coupling coordination in the southeast.[Conclusion] The overall urbanization process of He'nan Province is accelerating, and the economic urbanization and ecological environment pressure are having an important impact on the two major systems of urbanization and ecological environment. It will be necessary to strengthen the development of the central city of in Zhengzhou City and to promote the development of other cities in Southeast He'nan Province.
