In this study, an ecosystem service value evaluation method was applied to establish a coupling coordination degree model, quantify the coupling and coordination relationship between land-use cover change and ecosystem service value changes, and examine the impacts of different driving factors on ecosystem service value changes. The results were as follows. (1) In 2020, the coupling degree between these two variables peaked at a level above 0.9. (2) Their coupling degree was one in 2000, indicating a transformative shift and the entry into a new stage during this period within the study area. This study provides valuable information for the development of ecological compensation and restoration strategies within Horqin Sandy Land’s ecological civilization construction and development plan.
