摘　　要：研究鄂尔多斯市土地利用变化与生态系统服务价值(ESV)的时空演化特征对于推动生态环境保护和区域可持续发展具有重要意义。文中采用当量因子法估算鄂尔多斯市2000年至2020年间不同土地利用类型的ESV,并通过土地利用动态度和转移矩阵等方法分析土地利用变化对ESV的影响。研究表明:1)2000-2020年间,鄂尔多斯市土地利用类型发生显著变化,主要表现为草地和未利用地的相互转换以及建设用地的扩张。2)鄂尔多斯市ESV整体保持稳定,呈现波动下降趋势。其中草地和水域ESV的减少是导致ESV下降的主要原因,而林地ESV的增加则对整体ESV的提升具有积极作用。3)鄂尔多斯市ESV在空间上呈现出明显的区域性差异,东西地区ESV较高,南北ESV较低。基于以上分析,文中提出了针对性的优化策略,以促进鄂尔多斯市生态系统服务的提升和区域的可持续发展。The study of the spatio-temporal evolution characteristics of land use change and ecosystem service value(ESV)in Ordos is of great significance for promoting ecological environmental protection and regional sustainable development.The ESV of different land use types in Ordos from 2000 to 2020 is estimated using the equivalent factor method,and the impact of land use changes on ESV is analyzed by using land use dynamic degree and land use transfer matrix methods.The findings are as follows:1)Significant changes in land use types occurred during 2000~2020,mainly characterized by the mutual conversion between grassland and unused land,as well as the expansion of construction land.2)The overall ESV in Ordos remained stable,showing a fluctuating downward trend.The decrease in the ESV of grassland and water bodies is the primary reason for this decline,while the increase in forest land ESV contributed positively to the overall ESV improvement.3)The ESV in Ordos exhibited significant spatial differences,with higher ESV in the eastern and western regions,and lower ESV in the southern and northern regions.Based on the above analysis,targeted optimization strategies are proposed to enhance ecosystem services and promote sustainable development in Ordos.
