Persistent droughts in the late 20th century nearly caused ecosystem collapse in the Lower Tarim River region. Since the implementation of ecological water conveyance in 2000, groundwater levels have increased, vegetation has flourished, and a marked “greening” trend has occurred throughout the oases. However, a quantitative analysis of the drivers of these changes is lacking. This study integrates multi-source remote sensing data and field monitoring, using random forest modeling and Geographical Detector to monitor shifts in vegetation cover and their causes in the lower Tarim River and surrounding oases since 2000. In this period, groundwater has increased by approximately 0.07 m·yr −1 , surface-water areas have expanded, and regional air temperatures, particularly in winter, have increased markedly. Oasis vegetation cover has also increased significantly, while cropland has expanded markedly. Although natural vegetation has generally improved, cropland growth has encroached on desert riparian forests, intensifying interspecific competition within these communities and increasing potential ecological risks. Moreover, groundwater recovery and cold-season warming are key influencing factors associated with oasis greening, while recurrent droughts and interactions between climatic and hydrological variables further shape vegetation growth. Cumulatively, this study shows that effective water management supports oasis greening in arid areas, while highlighting the ecological risks of over-farming. Overall, this study provides new insights into how arid ecosystems respond to coupled climatic and anthropogenic drivers, and offers scientific support for ecological water-delivery regulation, agricultural water-use optimization, and riparian habitat conservation.","塔克拉玛干沙漠中的绿洲处于极端干旱区。20世纪后期的持续干旱几乎导致塔里木河下游地区生态系统崩溃。自2000年实施生态输水以来，地下水位上升，植被恢复，整个绿洲呈现出明显的“绿化”趋势。然而，对这些变化驱动因素的定量分析仍然缺乏。本研究整合多源遥感数据和野外监测，采用随机森林模型和地理探测器，监测2000年以来塔里木河下游及周边绿洲植被覆盖的变化及其成因。在此期间，地下水以约0.07 m·yr⁻¹的速率上升，地表水面积扩大，区域气温尤其是冬季气温显著升高。绿洲植被覆盖度也显著增加，同时耕地面积明显扩张。尽管自然植被总体改善，但耕地扩张侵占了荒漠河岸林，加剧了群落内种间竞争，增加了潜在生态风险。此外，地下水恢复和冷季增温是与绿洲绿化相关的关键影响因素，而反复出现的干旱以及气候与水文变量之间的交互作用进一步影响植被生长。总体而言，本研究表明有效的水资源管理支持干旱区绿洲绿化，同时凸显了过度耕作带来的生态风险。综上，本研究为理解干旱生态系统如何响应气候与人为驱动因素的耦合作用提供了新见解，并为生态输水调控、农业用水优化和河岸生境保护提供了科学支撑。",null,"Ecological Indicators","2026-09-14T00:00:00Z","论文",10,false,80,{"impact":17,"substance":18,"depth":17,"authority":19,"freshness":20,"relevant":21,"comment":22},18,22,14,8,1,"基于多源遥感与随机森林模型量化塔克拉玛干绿洲绿化驱动因素，结论对干旱区生态输水与农业用水优化有参考价值，但属区域研究，公共影响有限。",[24],{"name":10,"url":6},[26,27,28,29,30],"遥感监测","生态输水","荒漠绿洲","地下水恢复","农业用水",0,"10.1016\u002Fj.ecolind.2026.115510",{"doi":32,"openalex_id":34,"authors":35,"venue":10,"cited_by_count":31,"oa_url":6,"card":55,"direction":59,"ingested_from":61},"W7137834209",[36,38,41,44,46,48,50,52],{"name":37,"orcid":9},"Dinghao Li",{"name":39,"orcid":40},"Yasenjiang Kahaer","https:\u002F\u002Forcid.org\u002F0000-0002-2624-8317",{"name":42,"orcid":43},"Zhentao Dong","https:\u002F\u002Forcid.org\u002F0000-0003-4646-6079",{"name":45,"orcid":9},"Ruijia Liu",{"name":47,"orcid":9},"Anwar Abdureyim",{"name":49,"orcid":9},"Yulong Liu",{"name":51,"orcid":9},"Yanbo Wan",{"name":53,"orcid":54},"Qingdong Shi","https:\u002F\u002Forcid.org\u002F0000-0001-7369-6393",{"tldr":56,"method":57,"finding":58,"direction":59,"opportunity":60},"整合遥感与实地监测，量化塔克拉玛干绿洲2000年以来绿化驱动因素及生态风险。","多源遥感与实地监测，随机森林建模和地理探测器分析。","地下水回升与冬季增温驱动绿洲绿化，但耕地扩张侵占荒漠河岸林，生态风险上升。","农业遥感与作物表型","可延伸研究生态输水与农业用水优化协同调控，量化耕地扩张对河岸林生态风险的阈值。","openalex","2026-09-15T23:30:20.256810Z"]
