摘　　要：快速城市化引发的一系列生态环境问题会影响经济社会发展和资源环境承载。以广州市为研究对象,基于2012—2020年美国夜光传感器可见光近红外成像辐射搭载国家极轨卫星(NPP/VIIRS)采集的夜间灯光数据和陆地卫星(Landsat)多光谱遥感数据,利用综合灯光指数(CNLI)和遥感生态指数(RSEI),引入改进的耦合协调度模型,对2012—2020年广州市城市化水平、生态环境变化以及两者之间的耦合协调关系进行定量评估。结果表明:①CNLI能较为准确地反映各城区的城市化水平,广州市各城区城市发展水平呈现由中心向两端逐渐扩散的空间格局;②广州市RSEI空间分布状态由“V”字形集聚到逐渐分散,总体生态水平呈持续上升趋势,特别是生态环境较差的区域生态环境状况逐渐好转,但存在显著的区域差异;③广州市城市化与生态环境耦合协调度水平基本在不协调发展和转型发展之间,耦合协调度在各城区的分布情况与区域内经济发展水平具有一定的关联,经济发展较快、水平较高的城区耦合协调度较高。A series of ecological and environmental problems triggered by rapid urbanization will affect economic and social development,as well as the carrying capacity of resources and the environment.In this paper,Guangzhou City was studied,and night-time light remote sensing data collected by the national polar-orbiting partnership/visible infrared imaging radiometer suite(NPP/VIIRS)developed by the United States and Landsat multispectral remote sensing data from 2012 to 2020 were employed.Compounded night light index(CNLI)and remote sensing ecological index(RSEI)were introduced to the improved coupling and coordination degree model,so as to quantitatively evaluate the level of urbanization and ecological environment changes in Guangzhou City from 2012 to 2020,as well as the coupling and coordination relationship between urbanization and ecological environment changes.The results indicate that:①CNLI can accurately depict the level of urbanization across urban areas.The urban development level shows a spatial pattern of spreading from the center to the two ends of Guangzhou City.②The spatial distribution of RSEI in Guangzhou City changes from"V"-shaped clustering to gradual dispersion.The overall ecological level has been improved,particularly in the areas with poor ecological environments,but there are clear regional differences.③The coupling and coordination degree between urbanization and ecological environment of Guangzhou City are basically between uncoordinated development and transformed development.The coupling and coordination degree of each urban area are correlated with the level of economic growth.Specifically,the coupling and coordination degree are higher in urban areas with quicker and higher levels of economic development.
