摘　　要：黄河流域能源富集区资源利用和生态保护矛盾突出,为厘清其土地利用和生态系统服务变化特征,综合土地利用、社会经济统计等多源数据以及土地利用动态度、土地利用转移矩阵、修正的生态系统服务价值评估方法和灰色关联法等,对黄河流域能源富集区1990—2018年土地利用和生态系统服务价值的时空变化特征及其关联性进行了量化和分析。结果表明:1990—2018年黄河流域能源富集区以草地、未利用地和耕地为主;土地利用变化越来越活跃,以耕地和草地开发为建设用地,以及草地退化为未利用地为主;生态系统服务总价值呈现先减小后增大的变化趋势,1990—2018年总体减少了112.905亿元,其中气候调节、水文调节、废物处理和保持土壤服务对研究期内生态系统服务价值减小的贡献较大;研究期内生态系统服务价值的空间分布格局基本保持稳定,高值区主要位于研究区西北部,低值区主要包括宁夏全区以及甘肃白银、山西朔州和内蒙古呼和浩特等;1990—2018年草地和耕地与生态系统服务价值的关联度较高。In response to the lack of spatial and temporal dynamics analysis of ecosystem service values in energy⁃rich area,the spatial and temporal characteristics of land use and ecosystem service values in energy⁃rich area of the Yellow River Basin from 1990 to 2018 and their correlations were quantified and analyzed by integrating multi⁃source data such as land use and socio⁃economic statistics data,as well as multiple evaluation methods such as land use dynamic attitude,land use transfer matrix,modified evaluation method of ecosystem service value and grey correlation method.The results show that the energy⁃rich area in the Yellow River Basin is dominated by grassland,barren land and farmland during 1990 to 2018.The land use changes are increasingly active,dominated by the transfer of farmland and grassland to construction land,and the degradation of grassland to barren land.The total value of ecosystem services shows a trend of first decreasing and then increasing,and the overall reduction of the total value of ecosystem services is 11.2905 billion Yuan from 1990 to 2018,among which climate regulation,hydrology regulation,waste treatment and soil conservation services contribute most to the decrease of ecosystem services value during the study period.The spatial distribution pattern of ecosystem service value remains basically stable during the study period,with high-value area mainly located in the northwestern part of the study area,and low⁃value area mainly including Ningxia,Baiyin of Gansu Province,Shuozhou of Shanxi Province and Hohhot of Inner Mongolia.The correlations between grassland and ecosystem service value,farmland and ecosystem service value are comparatively higher from 1990 to 2018.
