摘　　要：在城镇化进程中,生态系统退化与人类需求提升之间的矛盾日益加剧,如何平衡城镇扩张及其生态环境响应以实现城市可持续发展已成为世界学者关注的热点。科学地揭示经济发达地区城镇化进程与生态系统服务间的交互胁迫机理,对于推动发达地区城镇化朝着健康有序的方向发展以及生态系统保护至关重要。然而,现存研究关于发达地区城镇化与生态系统服务交互胁迫机理的研究尚不充分,这无疑阻碍了发达地区在推进城镇化过程中制定出兼顾生态环境保护的有效政策。研究基于土地利用遥感监测数据与人口经济数据,测度了2000年、2010年和2020年广东省县域尺度城镇化进程及其生态系统服务的时空动态演变特征,并借助双变量空间自相关和耦合协调模型,深度挖掘两者间复杂的交互胁迫机理。结果显示:研究期间广东省生态系统服务供给能力整体呈现下降趋势,空间分布上则呈现自西北向东南逐渐减少的分布态势。双变量空间自相关结果显示,广东省城镇化与生态系统服务之间存在显著空间依赖性,城镇化水平的提升往往伴随生态系统服务能力的削弱。在耦合协调度方面,研究期间两者间的协调度呈现逐渐上升趋势,总体上仍以中度失调和低度协调为主,其中东南地区的城镇化与生态系统服务耦合协调度要明显高于西北部山区。研究结果可为深入理解广东省乃至类似发达地区的城镇化与生态系统服务如何协同演进提供有力的方法论借鉴和政策参考。During the process of urbanization,the conflict between ecosystem degradation and the growing demands of human needs is intensifying.Finding a balance between urban expansion and ecological and environmental responses has become a focal point for scholars worldwide in the pursuit of sustainable urban development.Therefore,accurately understanding and scientifically elucidating the complex interaction mechanisms between urbanization processes in economically developed areas and ecosystem services is essential for promoting healthy and orderly urbanization in these regions while ensuring effective protection of ecosystems.However,current academic research on the interrelated coercive relationship between urbanization and ecosystem services in developed regions is still inadequate,which undeniably hinders the development of effective policies that balance environmental protection with urbanization processes.In this study,we analyzed the spatial and temporal dynamics of county-scale urbanization and its associated ecosystem services in Guangdong Province for the years 2000,2010,and 2020,utilizing land-use remote sensing monitoring data alongside demographic and economic information.By integrating bivariate spatial autocorrelation analysis with coupling coordination models,this study explores the complex coercive interactions between urbanization and ecosystem services.Over the study period,the overall capacity for ecosystem service provision in Guangdong Province exhibited a declining trend,with its spatial distribution gradually decreasing from the northwest to the southeast.This study also reveals a significant spatial dependency between urbanization and ecosystem services in Guangdong Province,indicating that as urbanization intensifies,the capacity of ecosystem services tends to decline.In terms of coupling coordination degrees,there was a gradual increase from 2000 to 2020;however,the overall situation still reflects moderate disequilibrium and low coordination.Notably,the southeastern regions exhibit a more pro
