摘　　要：城市化进程与生态系统的协调发展是实现区域可持续发展的重要前提。利用2000、2010和2020年3期土地利用数据,结合ESV当量因子和空间自相关等方法,在探究快速城市化背景下,乌鲁木齐市土地利用对生态系统服务价值的影响。研究发现:(1)草地是乌鲁木齐市最主要的土地利用类型,除建设用地和未利用地的单一动态度为正值外,其他地类都显示出不同程度的负增长趋势;(2)2000—2020年乌鲁木齐市ESV总价值整体呈下降趋势,其间共减少37.05亿元。在空间分布上,ESV空间分异特征显著,呈南部高、北部和东部低的分布格局;(3)ESV与邻近网格具有较高的空间相关性。高—高聚集区集中在乌鲁木齐县及沿柴窝堡-达坂城区为中心的南北轴线附近,低—低聚集区主要集中在乌鲁木齐北部、东部和中心主城区。The coordinated development of urbanization and ecosystem is a crucial prerequisite for achieving regional sustainable development.Based on the land use data of 2000,2010 and 2020,combined with ESV equivalent factor and spatial autocorrelation methods,the impact of land use on ecosystem service value in Urumqi under the background of rapid urbanization were explored.The results showed that:(1)Grassland emerges as the most significant land use type in Urumqi.With the exception of construction land and unused land,which exhibit singular dynamic degrees,other types of land display varying degrees of negative growth.(2)The overall trend indicated a decline in total ESV value in Urumqi from 2000 to 2020,with a cumulative decrease amounting to 3.705 billion yuan.In terms of spatial distribution,ESV showed significant spatial differentiation,which was high in the south,low in the north and low in the east.(3)ESV demonstrated strong spatial correlation with adjacent grids.High-high clustering areas were primarily concentrated within Urumqi and along Chaiwopu-Dabancheng District's north-south axis,whereas low-low clustering areas mainly concentrate in Urumqi's northern,eastern regions as well as its main urban area.
