摘　　要：基于环塔里木经济带1990年、2005年和2020年3期土地利用数据,分析土地利用变化特征、生态系统服务价值(ESV)时空变化,并在地理探测器工具的支撑下探究环塔里木经济带ESV的空间分异机制。结果表明,1990—2020年,研究区草地、水域和林地面积均减少,建设用地、耕地和未利用地面积均增加;从外围山地向中部盆地,ESV存在明显的波动式递减现象;ESV冷热点呈“外部呈环状热点散布、内部呈片状冷点聚集”的空间分布格局;环塔里木经济带ESV空间分异的主要驱动因素是未利用地占比、气象因子和高程,各因素间交互作用表现为增强关系,自然因素的解释力高于社会经济因素。Based on the three periods of land use data of the economic belt around Tarim in 1990,2005 and 2020,the characteristics of land use change and spatial and temporal changes of ecosystem service value(ESV)were analyzed,and the spatial differentiation mechanism of ESV in the economic belt around Tarim was explored with the support of geographical detector tools.The results showed that from 1990 to 2020,the area of grassland,water area and forest land in the study area all decreased,while the area of construction land,cultivated land and unused land all increased.There was a significant wave-like decrease in ESV from the peripheral mountainous areas to the central basin.The spatial distribution pattern of ESV cold and hot spots was characterized by“a circular hot spot dispersion on the outside and a patchy cold spot aggregation on the inside”.The main driving factors of the spatial differentiation of ESV in the economic belt around Tarim were the proportion of unused land,meteorological factors and elevation.The interaction between various factors was enhanced,and the explanatory power of natural factors was higher than that of socio-economic factors.
