Abstract: The quantitative assessment of the relationship between land use(LULC) changes and ecosystem service values (ESV) is of great significance for optimizing land use structures and formulating sustainable land use policies. This study takes the Yunnan-Guizhou Plateau as the study area, and uses the ESV equivalence coefficient to quantitatively account for the value of ecosystem services in the Yunnan-Guizhou Plateau during the period of 2001—2020 and to analyze its LULC dynamics and its impact on ESV. The results show that the LULC patterns in the Yunnan-Guizhou Plateau have undergone significant changes over the past two decades, with a notable increase in forest area.The distribution of ESV exhibites marked spatial and temporal heterogeneity; the total ESV increased significantly from 638.1 billion yuan in 2001 to 746.99 billion yuan in 2020, mainly driven by forest restoration, the conversion of grassland to forest, and farmland to grassland. Therefore, we conclude that LULC changes resulting from ecological restoration measures have had a significantly positive impact on the total ESV of the Yunnan-Guizhou Plateau.
