[目的] 探究2013-2020年额济纳绿洲核心区景观稳定性动态及其驱动机制，为荒漠绿洲的生态恢复与可持续发展提供科学依据。[方法] 基于高分一号遥感影像，借助景观格局指数、景观稳定性模型与地理探测器，研究额济纳绿洲核心区景观稳定性动态及影响因素。[结果] ①额济纳绿洲核心区景观类型以未利用地、林地和草地为主，2020年3者占总面积的90.98%；2013-2020年，研究区景观连通性、均匀度降低，聚集度、优势度增加，多样性、异质性增强，景观形状趋于简单化、规则化。②研究区景观稳定性呈“总体不稳，局部较稳”状态；2013-2020年景观稳定性变化呈“大部分不显著，局部有变动，冷点多于热点”趋势。③地下水埋深、供水量和植被变化对研究区景观稳定性变化的影响较大；气候变化、人类活动(城镇建设、耕地扩张、旅游活动干扰等)和人口增长是地下水埋深、供水量和植被变化的诱因，间接引起景观稳定性的变化；各驱动因子之间存在交互增强效应。[结论] 2013-2020年额济纳绿洲核心区景观稳定性整体较低且呈下降趋势，干旱的气候条件、耕种、旅游和城镇建设等因素及其交互作用是导致研究区景观稳定性降低的重要因素。
[Objective] The landscape stability dynamics in the core area of Ejina Oasis from 2013 to 2020 and their driving mechanisms were determined in order to provide a basis for ecological restoration and sustainable development of the desert-oasis region. [Methods] Based on remote sensing images of Geosensor 1, a landscape pattern index, a landscape stability model, and GeoDetector, landscape stability dynamics of the core area of Ejina Oasis and its driving factors were investigated. [Results] ① The landscape type in the core area of Ejina Oasis was dominated by unused land, woodland. and grassland, accounting for 90.98% of the total area in 2020. Landscape connectivity and homogeneity of the study area decreased; aggregation, dominance, diversity, and heterogeneity increased; and landscape shapes tended to be simpler and regular from 2013 to 2020. ② Landscape stability of the study region was classified as “generally unstable, locally stable”, and the dynamics of landscape stability were classified as “mostly insignificant, locally variable, and more cold spots than hot spots” from 2013 to 2020. ③ Changes of groundwater depth, water supply, and vegetation cover had a great influence on the landscape stability dynamics of the study region. Climate change, human activities (urban construction, arable land expansion, tourism, etc.), and population growth were the causal factors for the above factors that indirectly caused changes in landscape stability. The driving factors had an interactive enhancement effect. [Conclusion] From 2013 to 2020, landscape stability for the entire study region was low and showed a downward trend. Factors such as arid climate condition, farming, tourism, and urban construction, and their interactions were the dominant factors that explained the reduction in landscape stability in the core area of Ejina Oasis.
