摘　　要：随着城镇化速度不断加快以及可持续发展理念的兴起,对城市进行生态经济耦合协调度研究有助于明确城市发展现状,评价其转型效果并对适合其的发展方向进行预测,对我国社会可持续发展具有重要的现实意义。基于MODIS卫星影像,统计出河南省2000-2020年间遥感生态指数(RSEI)。基于夜间灯光数据、人口栅格数据和PM_(2.5)数据构建了一种能够综合反映城市社会经济发展状况的遥感综合经济指数(RSCEI)。通过构建RSEI和RSCEI的耦合协调度模型,分析城市转型过程中生态和经济耦合协调情况。研究表明:(1)使用RSCEI反映城市社会发展状况,可以在社会活动的全过程对城市发展状况进行评价。相比传统的夜光遥感手段,其在经济欠发达地区反映的发展差异更加明显;(2)2000-2020年间,河南省生态环境质量呈现出“先改善后退化再恢复”的趋势。东部和西部区域生态环境质量优于中部区域;(3)2000-2020年间,河南省中心城区经济发展水平逐渐高于城市边缘区域。以第一产业为主的城市RSCEI呈现出先下降后上升的转型过程;以第二、三产业为主的城市靠近经济发达城市有利于城市社会经济发展;(4)河南省耦合协调度在2005年左右遇到转型发展中的瓶颈阶段,产业结构的调整导致耦合协调度持续下降,2015年后耦合协调度开始出现上升趋势,表明新的产业结构有利于河南省生态质量和社会经济协调发展。研究提出的RSCEI,填补了城市生态经济耦合协调度研究领域缺乏一种能够从城市发展全过程反映发展水平的空间化指数的空白,为城市可持续发展研究提供了新的遥感参考指标。With the accelerating pace of urbanization and the rising concept of sustainable development,studying the ecological and economic coupling of cities helps to clarify the current status of urban development,evaluates the effect of its transformation,and predicts suitable development directions,which holds significant practical importance for the sustainable development of China′s society.In this study,the Remote Sensing Ecological Index(RSEI)for Henan Province for the period from 2000-2020 was calculated based on MODIS satellite images.Using night light data,population grid data and PM2.5 data,this study constructed a Remote Sensing Comprehensive Economic Index(RSCEI)to comprehensively reflect urban social and economic development status.The coupled coordination degree model of RSEI and RSCEI is constructed to analyze the ecological and economic coupling and coordination in the process of urban transformation.The study shows that:(1)RSCEI can reflect the status of urban social development throughout the entire range of social activities.Compared with the traditional luminous remote sensing method,the development difference reflected by it in the less developed areas is more obvious;(2)From 2000 to 2020,the ecological environment quality in Henan Province showed a trend of“initial improvement,subsequent degradation,and eventual recovery”.The ecological environment quality of the eastern and western regions is better than that in the central region;(3)From 2000 to 2020,the economic development level of central urban areas in Henan Province is gradually higher than that of urban fringe areas.The RSCEI of cities dominated by primary industry shows a transition process of decreasing and then increasing;the proximity of cities dominated by secondary and tertiary industries to economically developed cities is conducive to urban socio⁃economic development;(4)The coupling coordination degree of Henan Province encountered a bottleneck stage in the transition and development in about 2005,and the adjustment of the in
