摘　　要：以准噶尔盆地东南部的煤炭资源富集区域为研究区,通过土地利用数据评估2005-2020年生态系统服务价值,借助空间统计方法探索土地利用转型与生态系统服务价值的时空变化特征,进一步分析了不同土地利用转型对生态系统服务价值产生的影响。研究结果表明,研究区土地利用转型明显,草地和未利用地相互转换规模较大;生态系统服务总价值呈下降趋势,主要受林地、草地和水域生态系统服务价值减少的影响;生态系统服务价值全局空间正相关性和聚集性显著但有减弱趋势,未利用地低值集聚面积增加;草地与未利用地之间的转换是生态系统服务价值变化的主要原因。为改善研究区生态系统服务价值,建议保持草地和林地的稳定性,合理规划建设用地并考虑增加水域面积,加强对未利用地的生态利用效率和生态修复措施。Taking the coal resource rich area in the southeast of the Junggar Basin as the study area,the ecosystem service value from 2005 to 2020 was evaluated by land use data,the spatial-temporal characteristics of land use transition and ecosystem service value were explored by spatial statistical methods,and the impact of different land use transition on ecosystem service value was further analyzed.The research results indicated that the land use transition in the study area was significant,with a large scale of conversion between grassland and unused land and a downward trend of total ecosystem service value,which mainly affected by the decrease in the value of ecosystem services in forests,grasslands,and water bodies;the global spatial positive correlation and clustering of ecosystem service value were significant but showed a weakening trend,with an increase in the low value clustering area of unused land;the conversion between grassland and unused land was the main reason for the change in ecosystem service value.To improve the ecosystem service value of the study area,it was suggested to maintain the stability of grassland and forest land,plan construction land reasonably and consider increasing water area,and strengthen the ecological utilization efficiency and ecological restoration measures of unused land.
