Failing to balance developmental considerations of the urbanization level (UL) and ecosystem services (ESs) causes issues such as land degradation and social conflict, presenting significant challenges for regional sustainable development. Although numerous studies reported the relationship between UL and ESs, only a few have explored the coupling coordination relationship between urbanization subsystems and ESs from a multidimensional perspective. This study aimed to measure the spatiotemporal characteristics of UL and ESs in Hunan Province from 2000 to 2018 using statistical data and remote sensing monitoring data regarding land use. The multidimensional coupling coordination relationship between urbanization systems and ESs was analyzed using a coupling coordination degree (CCD) model. The results showed that the UL of Hunan Province increased from 2000 to 2018, was spatially high in the east and low in the west, and extended outward from city centers. The average ecosystem services value (ESV) in Hunan Province showed a decreasing trend with some fluctuation. The average ESV in mountainous areas and lake areas was higher than that in the areas surrounding major urban agglomerations. Although the overall CCD between UL and ESs in Hunan Province increased during the study period and entered the coordination stage, the degree of coupling coordination between urbanization subsystems and ESs varied greatly. Thus, the findings of the present study can support the formulation of policies for ecosystem protection and sustainable urbanization in Hunan Province.
未能平衡城市化水平（UL）与生态系统服务（ESs）的发展考量会引发土地退化和社会冲突等问题，给区域可持续发展带来重大挑战。尽管众多研究报道了UL与ESs之间的关系，但只有少数研究从多维视角探讨了城市化子系统与ESs之间的耦合协调关系。本研究旨在利用土地利用的统计数据和遥感监测数据，测度2000年至2018年湖南省UL和ESs的时空特征。采用耦合协调度（CCD）模型分析城市化系统与ESs之间的多维耦合协调关系。结果表明，2000年至2018年湖南省的UL有所上升，空间上东高西低，且从市中心向外扩展。湖南省生态系统服务价值（ESV）均值呈下降趋势且有一定波动。山区和湖区的ESV均值高于主要城市群周边地区。尽管研究期间湖南省UL与ESs之间的整体CCD有所上升并进入协调阶段，但城市化子系统与ESs之间的耦合协调程度差异很大。因此，本研究结果可为湖南省生态系统保护和可持续城市化政策的制定提供支持。
