摘要: 土地利用覆盖(LULC)变化与生态系统服务价值(ESV)关系的定量评估对于科学优化土地利用结构和制定可持续土地利用政策具有重要意义。本文在生态恢复措施背景下以云贵高原为研究区域,采用ESV等效系数法定量核算2001—2020年云贵高原生态系统服务价值,并分析LULC动态变化及其对ESV的影响。结果表明,过去20年云贵高原的LULC格局发生了巨大变化,森林面积显著增加。ESV的分布具有明显的空间和时间异质性;总ESV从2001年的6381亿元显著增加至2020年的7 469.9亿元,主要受到森林恢复、草地向森林和耕地向草地转换的影响。因此,生态恢复措施引起的LULC变化对云贵高原总ESV的提高具有显著的积极影响。

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.
