摘　　要：【目的】都市圈作为各类资源与发展要素高度集聚的重要载体,在城镇化进程中面临着诸多生态环境挑战。基于人地关系,分析不同发展类型都市圈或不同都市圈圈域城镇化发展与生态环境的耦合机制,将为理解这些挑战提供新的视角。【方法】本文利用耦合协调模型、差异系数等方法,借助夜间灯光数据和遥感生态数据表征人类城镇化活动和地理生态环境,分析2000—2020年中国28个都市圈整体、不同发展类型都市圈、不同都市圈圈域的城镇化和生态环境质量及两者耦合协调的时空演变特征,并剖析两者协调机制。【结果】研究发现:(1)20年间28个都市圈整体城镇化发展水平不断提高,空间上总体呈现“东高西低”格局;相较于培育型和发展型都市圈,成熟型都市圈城镇化发展水平最高且增速最快;都市圈核心圈域城镇化发展水平优于外围圈域。(2)20年间28个都市圈整体生态环境质量呈波动下降趋势,空间上总体呈现“南高北低”格局;成熟型都市圈生态环境质量虽优于培育型和发展型都市圈,但下降最快;都市圈外围圈域生态环境质量优于核心圈域。(3)20年间28个都市圈整体城镇化与生态环境质量耦合协调度呈上升趋势,空间上总体呈现“东高西低”格局;相较于培育型和发展型都市圈,成熟型都市圈耦合协调度最高且增速最快;都市圈核心圈域耦合协调度优于外围圈域。新增的57个协调城市主要分布在培育型都市圈和外围圈域,表明两者在促进耦合协调发展方面潜力更大。(4)城镇化发展负向影响着生态环境质量,城镇化发展水平和城镇化与生态环境质量耦合协调度存在倒“U”型关系。【结论】在推进现代化都市圈建设中,各地应重视城镇化发展水平和城镇化与生态环境质量耦合协调度的倒“U”型关系,分区分类制定都市圈人地耦合共生的发展政策。[Objective]Metropolitan regions,as important carriers of highly concentrated resources and development factors,face numerous ecological and environmental challenges in the process of urbanization.Based on the human-environment relationship,analyzing the coupling mechanisms between urbanization and eco-environment in metropolitan regions of different development types or core-periphery regions will provide new perspectives for understanding these challenges.[Methods]This study used nighttime light data to represent human urbanization activities and remote sensing ecological data to represent the eco-environment.It employed coupling coordination models and coefficient of variation analyses to examine the spatiotemporal change of urbanization and eco-environmental quality across the whole metropolitan regions,different development types,and core-periphery regions from 2000 to 2020.It also analyzed the coupling coordination mechanisms between urbanization and eco-environmental quality.[Results]The findings indicate that:(1)Over 20 years,the urbanization level of the 28 metropolitan regions consistently increased,with a spatial pattern of high in the east and low in the west.Mature metropolitan regions showed the highest urbanization level and the fastest growth.Core regions had a higher urbanization level than peripheral regions.(2)Over 20 years,the eco-environmental quality of the 28 metropolitan regions generally declined,with a high in the south and low in the north pattern.Mature metropolitan regions had the best eco-environmental quality but saw the fastest decline.Peripheral regions outperformed core regions in eco-environmental quality.(3)Over 20 years,the coupling coordination degree of 28 metropolitan regions increased annually,with a high in the east and low in the west pattern.Mature metropolitan regions showed the highest coupling coordination degree and the fastest growth.Core regions had a higher coupling coordination degree than peripheral regions.The 57 new coordinated cities emerging during this peri
