Abstract: The relationship between ecosystem services (ESs) and human well-being (HWB) is a hotspot in the study of human-earth system coupling and sustainable development. Most studies have explored the impact of ESs on HWB based on the cascading framework, but it is difficult to directly reveal the interaction between ESs and HWB. In this study, we analyzed the coupling relationship between ESs and HWB in Shangluo City of Qinling Mountains as the study area. The results showed that the values of ecosystem services showed a fluctuating increase from 2000 to 2020. Shanyang County and Zhen’an County had higher ecosystem services values, while Shangnan County, Luonan County and Zhashui County were the lower-value areas. HWB increased significantly over time, with obvious spatial heterogeneity. The coupling relationship between ESs and HWB had been greatly improved from 2000 to 2020. In the early stage, the coupling between ESs and HWB was severely dysfunctional and accompanied by lagging ecosystem services. With the implementation of a series of environmental protection policies, their coupling was gradually balanced. In the later stage, their relationship showed a coordinated relationship with lagging human well-being. At present, the coupling relationship between ESs and HWB in Shangluo City is rigidly guided by HWB, and ESs play an elastic role in promoting or constraining. Therefore, at this stage, local government should pay attention to planning ecological space and enhancing the development connotation of HWB, so as to promote the strong coupling between ESs and HWB and pursue highquality development.
