This study used Sentinel-2 imagery and Random Forest classification on the Google Earth Engine (GEE) platform to map and analyse land-cover change in the wilayas of El-Bayadh and Naâma (south-western Algeria) between 2019 and 2025. Supervised classification of Sentinel-2A imagery produced land-cover maps for 2019 and 2025 (overall accuracy 88.9% and 91.5%; Kappa 0.87 and 0.90, respectively). Transition matrices quantified flows to and from the 'Dunes and Shifting Sands' class. Dune formations remained relatively stable, with 5.37 million ha unchanged, while the class expanded by 219,458 ha (+3.7%) overall. This expansion was predominantly fed by conversion from grazing land (627,335 ha), bare soil (57,395 ha) and agricultural land (32,959 ha), reflecting intensifying desertification linked to climate variability, overgrazing, deforestation and cropland abandonment. Conversely, 455,993 ha of former dune surfaces reverted to grazing land and 86,631 ha to bare soil, corresponding mainly to areas where natural vegetation recovered or where biological dune-fixation works were implemented. These results confirm the value of multi-temporal remote sensing combined with GEE for monitoring large-scale land degradation. Critically, the study identifies management opportunities: areas undergoing dune stabilization through vegetation recovery or anti-desertification engineering provide model zones for scaled intervention.","沙丘入侵是干旱和半干旱地区最重要的土地退化过程之一，随着沙丘地貌以牺牲牧草地和农用地为代价不断扩张，产生了复杂的时空动态。本研究利用Sentinel-2影像和随机森林分类方法，在Google Earth Engine（GEE）平台上对阿尔及利亚西南部埃尔贝亚德省和纳马省2019年至2025年间的土地覆盖变化进行了制图与分析。对Sentinel-2A影像进行监督分类，生成了2019年和2025年的土地覆盖图（总体精度分别为88.9%和91.5%；Kappa系数分别为0.87和0.90）。通过转移矩阵量化了“沙丘与流沙”类别的流入与流出。沙丘地貌总体保持相对稳定，537万公顷未发生变化，但该类别整体扩张了219,458公顷（+3.7%）。这一扩张主要来源于牧草地（627,335公顷）、裸土（57,395公顷）和农用地（32,959公顷）的转化，反映出与气候变率、过度放牧、森林砍伐和耕地撂荒相关的荒漠化加剧。相反，455,993公顷的原沙丘表面恢复为牧草地，86,631公顷恢复为裸土，主要对应自然植被恢复或生物固沙工程实施的区域。这些结果证实了多时相遥感结合GEE在大尺度土地退化监测中的价值。重要的是，本研究识别了管理机遇：通过植被恢复或防沙治沙工程实现沙丘固定的区域，为规模化干预提供了示范样区。",null,"Journal of Degraded and Mining Lands Management","2026-10-01T00:00:00Z","论文",10,false,78,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},16,22,18,13,9,1,"基于Sentinel-2与随机森林的阿尔及利亚西南部沙丘入侵监测研究，方法成熟、数据详实，对荒漠化遥感监测有参考价值，但区域性强、与国内三农信息化关联较弱。",[25],{"name":10,"url":6},[27,28,29,30,31],"Sentinel-2","土地退化","遥感监测","Google Earth Engine","荒漠化防治",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},"I3","remote-sensing","遥感与农情监测","\u002Ftopic\u002Fdigital-agriculture\u002Fremote-sensing","I",[],{"status":40,"locked":14,"version":41,"method":42,"evidence":43},"classified","2026-10-22.2","rules",{"candidates":44,"agricultural_evidence":46},[45,52,59,65,70],{"code":33,"score":21,"supported":46,"title":47,"abstract":48,"tags":51},true,[],[49,50],"遥感","remote sensing",[30,27,29],{"code":53,"score":54,"supported":46,"title":55,"abstract":56,"tags":58},"H2",3,[],[57],"soil",[],{"code":60,"score":54,"supported":46,"title":61,"abstract":62,"tags":64},"H7",[],[63],"干旱",[],{"code":66,"score":22,"supported":14,"title":67,"abstract":68,"tags":69},"H1",[],[],[28],{"code":71,"score":22,"supported":14,"title":72,"abstract":73,"tags":74},"H6",[],[],[31],[76,77],"阿尔及利亚 沙丘入侵 Sentinel-2","El-Bayadh Naâma 土地覆盖变化","阿尔及利亚沙丘入侵Sentinel-2-3892","10.15243\u002Fjdmlm.2026.134.11367",{"doi":79,"openalex_id":81,"authors":82,"venue":10,"cited_by_count":97,"oa_url":6,"card":98,"direction":102,"ingested_from":104},"W7214937065",[83,86,89,92,94],{"name":84,"orcid":85},"Naîmi Bendouina","https:\u002F\u002Forcid.org\u002F0000-0002-9776-1660",{"name":87,"orcid":88},"Lakhdar Guérine","https:\u002F\u002Forcid.org\u002F0000-0003-0836-2703",{"name":90,"orcid":91},"Nassira Boukaya","https:\u002F\u002Forcid.org\u002F0000-0002-6201-3523",{"name":93,"orcid":9},"Djallal Moumen",{"name":95,"orcid":96},"Omar Belabid","https:\u002F\u002Forcid.org\u002F0000-0002-7736-2259",0,{"tldr":99,"method":100,"finding":101,"direction":102,"opportunity":103},"基于Sentinel-2与随机森林监测阿尔及利亚西南部2019-2025年沙丘侵占与土地覆盖变化。","Sentinel-2影像、随机森林分类、Google Earth Engine、","沙丘面积增21.9万公顷（+3.7%），主要来自牧草地、裸土和耕地，同时部分沙地经植被恢复固定。","农业遥感与作物表型","可结合多源时序遥感与治沙工程数据，量化生物固沙措施的长期成效并识别可推广的修复优先区。","openalex","2026-10-01T23:30:27.844225Z",{"total":107,"page":22,"page_size":107,"items":108},6,[109,193,255,339,396,474],{"id":110,"title":111,"url":112,"summary":113,"summary_zh":114,"content":9,"source_name":115,"source_url":112,"published_at":116,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":117,"score_detail":118,"sources":122,"tags":124,"primary_topic":127,"secondary_topics":132,"classification":134,"search_phrases":177,"slug":180,"view_count":22,"doi":181,"paper":182,"created_at":192},3364,"Geographical Analysis of Desertification and Environmental Degradation and the Spatial Variation of Their Manifestations in Parts of the Jifara Plain","https:\u002F\u002Fdoi.org\u002F10.65405\u002Fsjh.2.3.85","This research aims to analyze the spatial variation of desertification and environmental degradation manifestations in the Al-Jfara Plain, identify the degrees, intensity, and geographical distribution of desertification, and determine the main manifestations associated with land degradation. It also seeks to identify the effects of natural and human factors on the spread of desertification and determine the areas most vulnerable to it, thereby contributing to efforts to conserve natural resources and reduce land degradation. The research adopted the analytical approach as the main method for analyzing data related to degraded lands, vegetation cover, rangelands, rainfall, erosion, and agricultural and livestock production. It also employed the descriptive approach to present the natural and human characteristics of the research area, as well as the comparative approach to compare different spatial units and time periods. The research further relied on geographical references, scientific studies, and available data, using percentages and rates of change to compare levels of degradation. The research concluded that there is clear spatial variation in the manifestations of desertification and environmental degradation across the Al-Jfara Plain. Wind erosion, declining vegetation cover, drought, and rainfall variability emerged as the most prominent manifestations of degradation. In addition, overgrazing, excessive exploitation of soil and groundwater resources, and urban expansion contributed to increasing pressure on natural resources. The research recommends reducing overgrazing, rationalizing groundwater use, combating erosion, increasing vegetation cover, regulating land use, and enhancing environmental awareness. It also proposes periodic monitoring of desertification using remote sensing and Geographic Information Systems (GIS), preparing updated maps of land degradation, and implementing projects for the rehabilitation of degraded lands.","本研究旨在分析贾法拉平原荒漠化与环境退化表现的空间差异，识别荒漠化的程度、强度及地理分布，并确定与土地退化相关的主要表现。研究还力求查明自然因素和人为因素对荒漠化蔓延的影响，确定最易受荒漠化影响的区域，从而为保护自然资源和减少土地退化的努力作出贡献。研究采用分析方法作为分析与退化土地、植被覆盖、牧场、降雨、侵蚀以及农牧业生产相关数据的主要方法，同时运用描述性方法呈现研究区域的自然和人文特征，并采用比较方法对不同空间单元和时间段进行比较。研究还依托地理文献、科学研究和现有数据，利用百分比和变化率来比较退化程度。研究得出结论：贾法拉平原各地荒漠化与环境退化表现在明显的空间差异。风蚀、植被覆盖下降、干旱和降雨变率是最突出的退化表现。此外，过度放牧、土壤和地下水资源的过程开发以及城市扩张也加剧了对自然资源的压力。研究建议减少过度放牧、合理利用地下水、防治侵蚀、增加植被覆盖、规范土地利用并增强环境意识。研究还提出利用遥感和地理信息系统（GIS）对荒漠化进行定期监测，编制更新的土地退化地图，并实施退化土地恢复项目。","Shihab Journal of Humanities","2026-09-23T00:00:00Z",55,{"impact":119,"substance":19,"depth":120,"authority":107,"freshness":21,"relevant":22,"comment":121},8,14,"区域荒漠化空间分析研究，方法常规、结论有参考价值，但属地方性学术成果，公共影响有限。",[123],{"name":115,"url":112},[28,29,125,126,31],"GIS","植被覆盖",{"code":128,"slug":129,"name":130,"path":131,"parent_code":37},"I4","gis","GIS与空间分析","\u002Ftopic\u002Fdigital-agriculture\u002Fgis",[133],{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},{"status":40,"locked":14,"version":41,"method":42,"evidence":135},{"candidates":136,"agricultural_evidence":46},[137,143,147,152,157,163,169,173],{"code":128,"score":13,"supported":46,"title":138,"abstract":139,"tags":142},[],[140,125,141],"地理信息","geographic information",[125],{"code":33,"score":119,"supported":46,"title":144,"abstract":145,"tags":146},[],[49,50],[126,29],{"code":53,"score":107,"supported":46,"title":148,"abstract":149,"tags":151},[],[150,57],"土壤",[],{"code":60,"score":107,"supported":46,"title":153,"abstract":154,"tags":156},[],[63,155],"drought",[],{"code":158,"score":54,"supported":46,"title":159,"abstract":160,"tags":162},"C",[],[161],"livestock",[],{"code":164,"score":54,"supported":46,"title":165,"abstract":166,"tags":168},"H3",[],[167],"水资源",[],{"code":66,"score":22,"supported":14,"title":170,"abstract":171,"tags":172},[],[],[28],{"code":71,"score":22,"supported":14,"title":174,"abstract":175,"tags":176},[],[],[31],[178,179],"GIS 荒漠化 遥感监测","荒漠化防治 土地退化 植被覆盖 遥感监测","GIS荒漠化遥感监测-3364","10.65405\u002Fsjh.2.3.85",{"doi":181,"openalex_id":183,"authors":184,"venue":115,"cited_by_count":97,"oa_url":112,"card":187,"direction":102,"ingested_from":104},"W7214127171",[185],{"name":186,"orcid":9},"حسنية السني رجب البكوري",{"tldr":188,"method":189,"finding":190,"direction":102,"opportunity":191},"分析吉法拉平原荒漠化与环境退化的空间差异及主要表现，并提出防治建议。","采用分析法、描述法与比较法，结合地理文献和统计数据评估退化程度。","风蚀、植被减少、干旱和降水变率是主要退化表现，过度放牧与地下水超采加剧压力。","可结合遥感与GIS开展荒漠化动态监测，构建多因子退化风险评估模型。","2026-09-24T23:30:21.130938Z",{"id":194,"title":195,"url":196,"summary":197,"summary_zh":198,"content":9,"source_name":199,"source_url":196,"published_at":200,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":201,"score_detail":202,"sources":207,"tags":209,"primary_topic":212,"secondary_topics":213,"classification":214,"search_phrases":226,"slug":229,"view_count":22,"doi":230,"paper":231,"created_at":254},5168,"Study on barchan dune movement velocity using fiber optic sensing theory and technology: a case study in the Tengger Desert, China","https:\u002F\u002Fdoi.org\u002F10.1088\u002F1402-4896\u002Faeb58f","Abstract Dune movement velocity monitoring is essential to the study of desert ecosystem evolution, the protection of surrounding agriculture, and the prevention of wind erosion. However, traditional monitoring technologies such as field marking, GPS positioning, and image remote sensing suffer from limited accuracy and resistance to interference under harsh desert conditions. To address these issues, this study integrates Brillouin optical time-domain reflectometry (BOTDR) with aeolian sand dynamics to establish a theory and methodology for measuring dune movement velocity via optical fiber sensing. Specifically, a physical model is constructed to describe the complete transmission chain from wind forcing, through dune deformation and optical fiber strain transfer. Utilizing the proposed theory and method, numerical simulations are performed on barchan dunes in the Tengger Desert to analyze the movement velocities of dunes with varying widths, and the results are compared with those obtained through traditional monitoring technologies. It indicates that the proposed method exhibits advantages in terms of monitoring frequency and spatial resolution. The theory and methodology provide technical support for the scientific monitoring of mobile dunes and the prevention of desertification.","摘要 沙丘移动速度监测对沙漠生态系统演化研究、周边农业保护及风蚀防治具有重要意义。然而，野外标记、GPS定位、影像遥感等传统监测技术在沙漠恶劣条件下存在精度有限、抗干扰能力不足等问题。针对上述问题，本研究将布里渊光时域反射技术(BOTDR)与风沙动力学相结合，建立了基于光纤传感的沙丘移动速度测量理论与方法。具体而言，构建了描述风力驱动、沙丘变形至光纤应变传递完整链条的物理模型。利用所提理论与方法，对腾格里沙漠新月形沙丘开展数值模拟，分析了不同宽度沙丘的移动速度，并与传统监测技术所得结果进行对比。结果表明，所提方法在监测频率和空间分辨率方面具有优势。该理论与方法为流动沙丘科学监测及荒漠化防治提供了技术支撑。","Physica Scripta","2026-10-16T00:00:00Z",71,{"impact":203,"substance":204,"depth":205,"authority":20,"freshness":21,"relevant":22,"comment":206},12,20,17,"将BOTDR光纤传感用于沙丘移动速度监测，方法新颖且对荒漠化防治与农田风蚀防护有实用价值，但属细分领域论文，影响范围有限。",[208],{"name":199,"url":196},[29,31,210,211],"光纤传感","风沙监测",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":215},{"candidates":216,"agricultural_evidence":46},[217,222],{"code":33,"score":218,"supported":46,"title":219,"abstract":220,"tags":221},7,[],[49,50],[29],{"code":71,"score":22,"supported":14,"title":223,"abstract":224,"tags":225},[],[],[31],[227,228],"腾格尔沙漠 沙丘移动 光纤传感","BOTDR 沙丘移动速度","腾格尔沙漠沙丘移动光纤传感-5168","10.1088\u002F1402-4896\u002Faeb58f",{"doi":230,"openalex_id":232,"authors":233,"venue":199,"cited_by_count":97,"oa_url":9,"card":248,"direction":102,"ingested_from":104},"W7222732569",[234,236,239,241,243,245],{"name":235,"orcid":9},"Kesen Tao",{"name":237,"orcid":238},"Xin Ma","https:\u002F\u002Forcid.org\u002F0009-0001-2609-8718",{"name":240,"orcid":9},"Jinsheng Yu",{"name":242,"orcid":9},"Zhiting Li",{"name":244,"orcid":9},"Wenhai Sun",{"name":246,"orcid":247},"Xingcai Li","https:\u002F\u002Forcid.org\u002F0000-0003-3257-1601",{"tldr":249,"method":250,"finding":251,"direction":252,"opportunity":253},"提出基于BOTDR光纤传感的沙丘移动速度测量理论与方法，并在腾格里沙漠验证。","将布里渊光时域反射技术与风沙动力学结合，构建风-沙丘变形-光纤应变传递模型并数值","该方法在监测频率和空间分辨率上优于传统标记、GPS和遥感技术。","其他","可将光纤传感用于农田风蚀与沙丘入侵的实时监测预警，弥补传统遥感精度不足。","2026-10-17T23:30:28.493340Z",{"id":256,"title":257,"url":258,"summary":259,"summary_zh":260,"content":9,"source_name":261,"source_url":258,"published_at":262,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":263,"score_detail":264,"sources":266,"tags":268,"primary_topic":272,"secondary_topics":276,"classification":278,"search_phrases":298,"slug":301,"view_count":97,"doi":302,"paper":303,"created_at":338},4366,"Article topic: comprehensive assessment of soil and flora contamination by heavy metals in the zone of influence of the Nikolaevskaya enrichment plant","https:\u002F\u002Fdoi.org\u002F10.51886\u002F1999-740x_2026_3_46","Agricultural lands in East Kazakhstan region cover a significant area, with large portions of pasture and cropland situated in close proximity to operating industrial facilities.

The paper presents the development and testing of an index-based algorithm for detecting indicators of soil erosion by water from Sentinel-2 remote sensing data, considered as the first practical stage in constructing a hybrid physics-based mass-transport model with neural-network parameter identification. Materials and Methods . The algorithm relies on joint analysis of time series of the Normalized Difference Vegetation Index (NDVI) and the Bare Soil Index (BSI), followed by spatial change detection (ΔBSI) with threshold filtering at the 90th percentile. The algorithm was first validated on synthetic data and then applied to real Sentinel-2 imagery for two test sites – the Kamensky District of Rostov Oblast and the vicinity of Moldovanskoye village, Krymsky District, Krasnodar Krai – covering 10 dates within 2024. Results. The algorithm is shown to consistently identify spatially localised zones of increasing bare-soil exposure. Discussion . A key limitation – the inability to distinguish erosion-related exposure from ordinary agrotechnical bare soil — is discussed, along with directions for resolving it (digital elevation model overlay, multi-year analysis). Conclusion . An index-based algorithm for detecting indicators of water-induced soil erosion from Sentinel-2 multispectral time series was developed and validated. Verification on synthetic data and application to two real test areas in southern Russia confirmed its operability while demonstrating the need to separate erosion-related changes from agricultural soil exposure in subsequent model development.","引言。本文介绍了一种基于指数的算法开发与测试，该算法用于从Sentinel-2遥感数据中检测水蚀土壤侵蚀指标，被视为构建基于物理的质量输运混合模型并结合神经网络参数辨识的第一个实践阶段。材料与方法。该算法依赖于对归一化植被指数（NDVI）和裸土指数（BSI）时间序列的联合分析，随后进行空间变化检测（ΔBSI），并在第90百分位数处进行阈值滤波。该算法首先在合成数据上进行了验证，然后应用于两个测试点的真实Sentinel-2影像——罗斯托夫州卡缅斯基区和克拉斯诺达尔边疆区克里姆斯克区摩尔多瓦诺夫斯科耶村附近——覆盖2024年内的10个日期。结果。结果表明，该算法能够一致地识别出裸土暴露增加的空间局部区域。讨论。讨论了关键局限性——无法区分与侵蚀相关的裸土暴露和普通农技作业造成的裸土——以及解决该问题的方向（叠加数字高程模型、多年分析）。结论。开发并验证了一种基于指数的算法，用于从Sentinel-2多光谱时间序列中检测水蚀土壤侵蚀指标。在合成数据上的验证以及在俄罗斯南部两个真实测试区域的应用证实了其可操作性，同时表明在后续模型开发中有必要将与侵蚀相关的变化与农业裸土暴露区分开来。","COMPUTATIONAL MATHEMATICS AND INFORMATION TECHNOLOGIES",70,{"impact":203,"substance":204,"depth":205,"authority":20,"freshness":119,"relevant":22,"comment":348},"提出基于NDVI与BSI时序的土壤水蚀指标遥感识别算法，并在俄罗斯南部两个试验区验证，方法有新意但属区域尺度研究，对国内农业遥感监测有参考价值。",[350],{"name":345,"url":342},[352,27,353,29,354],"智慧农业","NDVI","土壤侵蚀",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[357],{"code":53,"slug":57,"name":273,"path":274,"parent_code":275},{"status":40,"locked":14,"version":41,"method":42,"evidence":359},{"candidates":360,"agricultural_evidence":46},[361,366,370],{"code":33,"score":204,"supported":46,"title":362,"abstract":364,"tags":365},[363],"multispectral",[49,50,363],[353,27,29],{"code":53,"score":120,"supported":46,"title":367,"abstract":368,"tags":369},[57],[150,57],[],{"code":371,"score":22,"supported":14,"title":372,"abstract":373,"tags":374},"I1",[],[],[352],[376,377],"Sentinel-2 土壤侵蚀 遥感","罗斯托夫州 克拉斯诺达尔 土壤侵蚀","Sentinel-2土壤侵蚀遥感-4365",2,"10.23947\u002F2587-8999-2026-10-3-49-57",{"doi":380,"openalex_id":382,"authors":383,"venue":345,"cited_by_count":97,"oa_url":342,"card":390,"direction":102,"ingested_from":104},"W7220651513",[384,387],{"name":385,"orcid":386},"V.

This study presents an integrated evaluation of drought conditions by applying established individual and composite drought indices within a unified multi-source framework that combines ground-based meteorological data with satellite-derived datasets, including MODIS land surface products and GPM\u002FTRMM precipitation estimates, and is implemented on the Google Earth Engine platform. A set of drought indicators representing vegetation condition, thermal stress, precipitation deficit, and soil moisture variability was analyzed alongside five composite indices to provide a multi-dimensional assessment of drought dynamics. The analysis was conducted across monthly, seasonal, and annual timescales for Tehran, Iran, over the period 2000–2022. In addition, trend significance was assessed using the Mann–Kendall test and Sen’s slope estimator to quantify long-term changes in drought behavior. The results indicate that composite indices provide a more coherent representation of drought evolution and are more effective in capturing the interaction among key climatic drivers. In particular, the analysis reveals a transition from precipitation-driven droughts (e.g., 2008 and 2016) to increasingly temperature-driven drought conditions (e.g., 2022), associated with elevated potential evapotranspiration and thermal stress. This highlights the growing importance of atmospheric evaporative demand in intensifying drought severity under warming conditions. From an applied perspective, the proposed framework supports drought early warning, spatial risk assessment, and informed decision-making in water resource management and agricultural planning. However, the reliability of the results depends on data quality, spatial resolution, and the representation of key drought drivers and should therefore be interpreted with these limitations in mind. The study demonstrates that the integrated application of multi-source data and multi-scale drought indices provides a robust basis for understanding and monitoring drought dynamics in semi-arid urban environments.","准确的干旱监测对于可持续水资源管理至关重要，尤其是在气象观测稀疏且空间异质性强的半干旱地区。本研究在统一的多源框架内，应用已有的单一和综合干旱指数对干旱状况进行综合评估，该框架将地面气象数据与卫星遥感数据集（包括MODIS地表产品和GPM\u002FTRMM降水估算）相结合，并在Google Earth Engine平台上实现。研究分析了表征植被状况、热胁迫、降水亏缺和土壤湿度变率的干旱指标集以及五种综合指数，以对干旱动态进行多维评估。分析在月、季和年尺度上针对伊朗德黑兰2000—2022年期间开展。此外，采用Mann–Kendall检验和Sen斜率估计器评估趋势显著性，以量化干旱行为的长期变化。结果表明，综合指数能更一致地表征干旱演变，且更能有效捕捉关键气候驱动因子之间的相互作用。具体而言，分析揭示了从降水驱动型干旱（如2008年和2016年）向日益增强的温度驱动型干旱（如2022年）的转变，这与潜在蒸散和热胁迫升高有关。这凸显了在变暖条件下大气蒸发需求在加剧干旱严重程度方面日益重要的作用。从应用角度看，所提出的框架可支持干旱预警、空间风险评估以及水资源管理和农业规划中的知情决策。然而，结果的可靠性取决于数据质量、空间分辨率以及关键干旱驱动因子的表征，因此在解读时应考虑这些局限性。本研究表明，多源数据与多尺度干旱指数的综合应用为理解和监测半干旱城市环境中的干旱动态提供了稳健基础。","Journal of Atmospheric and Solar-Terrestrial Physics",74,{"impact":120,"substance":405,"depth":19,"authority":20,"freshness":119,"relevant":22,"comment":406},21,"多源遥感与地面指数融合的干旱监测框架，方法扎实、结论有新意，但属区域案例研究，产业影响有限。",[408],{"name":402,"url":399},[410,411,29,30,412],"农业气象","水资源管理","干旱预警",{"code":60,"slug":414,"name":415,"path":416,"parent_code":275},"climate","气候适应与防灾减灾","\u002Ftopic\u002Fenvironment\u002Fclimate",[418,419],{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},{"code":164,"slug":420,"name":421,"path":422,"parent_code":275},"irrigation","水资源与灌溉","\u002Ftopic\u002Fenvironment\u002Firrigation",{"status":40,"locked":14,"version":41,"method":42,"evidence":424},{"candidates":425,"agricultural_evidence":46},[426,430,434,440,444],{"code":60,"score":17,"supported":46,"title":427,"abstract":428,"tags":429},[155],[63,155],[410,412],{"code":33,"score":20,"supported":46,"title":431,"abstract":432,"tags":433},[50],[49],[30,29],{"code":164,"score":13,"supported":46,"title":435,"abstract":436,"tags":439},[],[167,437,438],"water resource","evapotranspiration",[411],{"code":53,"score":107,"supported":46,"title":441,"abstract":442,"tags":443},[],[150,57],[],{"code":445,"score":54,"supported":46,"title":446,"abstract":447,"tags":449},"J1",[],[448],"农业规划",[],[451,452],"MODIS GPM 干旱指数","德黑兰 干旱监测 遥感","MODISGPM干旱指数-4030","10.1016\u002Fj.jastp.2026.106987",{"doi":454,"openalex_id":456,"authors":457,"venue":402,"cited_by_count":97,"oa_url":399,"card":468,"direction":102,"ingested_from":104},"W7215092640",[458,461,463,465],{"name":459,"orcid":460},"Hadi Siasar","https:\u002F\u002Forcid.org\u002F0000-0002-9323-4345",{"name":462,"orcid":9},"Mahboube Ebrahimi",{"name":464,"orcid":9},"Mehdi Bahrami",{"name":466,"orcid":467},"Hossein Hamidifar","https:\u002F\u002Forcid.org\u002F0000-0001-9054-0120",{"tldr":469,"method":470,"finding":471,"direction":102,"opportunity":472},"整合遥感与地面数据，在GEE上评估德黑兰2000–2022年多尺度干旱动态。","MODIS、GPM\u002FTRMM与气象数据，构建5种复合干旱指数，Mann-Kend","复合指数更一致；干旱由降水驱动转向温度驱动，蒸散需求加剧干旱。","可引入机器学习融合多源指数，提升半干旱区干旱预警的时空精度与驱动归因。","2026-10-02T23:30:24.756475Z",{"id":475,"title":476,"url":477,"summary":478,"summary_zh":479,"content":9,"source_name":480,"source_url":477,"published_at":481,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":482,"score_detail":483,"sources":485,"tags":487,"primary_topic":491,"secondary_topics":492,"classification":493,"search_phrases":512,"slug":515,"view_count":22,"doi":516,"paper":517,"created_at":531},3897,"Impact of Land Use Change on Sandstorm Disaster in Tarim Basin of China","https:\u002F\u002Fdoi.org\u002F10.3390\u002Fland15101840","Arid oasis–desert systems in inland basins are increasingly threatened by human-induced land-use transformation and aggravated dust storm hazards, whereas the nonlinear coupling mechanisms and critical land-use thresholds controlling dust pollution remain poorly understood. Taking township units of southern Xinjiang as the research scope over a 25-year period, this study integrated remote sensing and geographic information system techniques, geographically weighted regression, and piecewise threshold analysis to explore the long-term spatial coupling relationship between land-use transitions and dust-related PM10 variations, and to identify the threshold effects of diverse land-use types on dust emissions. The results indicate evident spatial non-stationarity in the co-variation patterns of land-use change and dust pollution. Intensive land-use disturbance and elevated dust risks are concentrated in oasis–desert ecotones, while desert hinterlands and high mountainous areas exhibit stable land-use conditions and weak human interference. Land-use factors exert limited explanatory capacity for dust variation due to dominant meteorological background controls. Distinct threshold effects exist among different land-use categories. Bare land and impervious surfaces function as dust-promoting land types with sharp increases in dust pollution beyond their respective critical proportions. Cropland exhibits a dual nonlinear effect, providing dust-suppression benefits within a reasonable proportion range but aggravating dust risks under excessive reclamation through the destruction of ecological buffer zones. Snow cover, forest, grassland, and water bodies serve as effective dust-suppressing land types, whose mitigation benefits stabilize after reaching minimum critical coverage, while shrubs show no significant regulatory effect on dust pollution. The oasis–desert ecotone represents the most sensitive zone for dust prevention. Targeted zoning management guided by land-use threshold constraints is essential to optimize regional ecological regulation, replace blind single afforestation strategies, and integrate ecological threshold criteria into territorial spatial planning. Land-use adjustment can effectively mitigate anthropogenic dust emissions, yet comprehensive dust control requires coordinated meteorological early warning systems and balanced management of agricultural production and ecological risk prevention.","内陆盆地的干旱绿洲–荒漠系统日益受到人为土地利用转型和沙尘暴危害加剧的威胁，而控制沙尘污染的非线性耦合机制及关键土地利用阈值仍认识不足。本研究以新疆南部乡镇单元为研究范围，跨越25年，综合遥感与地理信息系统技术、地理加权回归和分段阈值分析，探讨土地利用转型与沙尘相关PM10变化的长期空间耦合关系，并识别不同土地利用类型对沙尘排放的阈值效应。结果表明，土地利用变化与沙尘污染的共变格局存在明显的空间非平稳性。强烈的土地利用扰动和较高的沙尘风险集中于绿洲–荒漠过渡带，而荒漠腹地和高山地区土地利用状况稳定、人为干扰较弱。由于气象背景的主导控制作用，土地利用因子对沙尘变化的解释能力有限。不同土地利用类别之间存在明显的阈值效应。裸地和硬化地表属于促沙土地利用类型，超过各自临界比例后沙尘污染急剧增加。耕地表现出双重非线性效应，在合理比例范围内具有抑沙效益，但过度开垦通过破坏生态缓冲带而加剧沙尘风险。积雪、林地、草地和水体为有效的抑沙土地利用类型，其减缓效益在达到最低临界覆盖度后趋于稳定，而灌木对沙尘污染无显著调控作用。绿洲–荒漠过渡带是防沙最为敏感的区域。以土地利用阈值约束为导向的针对性分区管理，对于优化区域生态调控、替代盲目单一造林策略以及将生态阈值标准纳入国土空间规划至关重要。土地利用调整可有效减缓人为沙尘排放，但综合防沙需要协调气象预警系统与农业生产和生态风险防范的平衡管理。","Land","2026-09-30T00:00:00Z",79,{"impact":19,"substance":18,"depth":19,"authority":20,"freshness":119,"relevant":22,"comment":484},"基于25年遥感与GIS数据揭示土地利用变化对沙尘污染的阈值效应，方法新颖、结论可靠，对干旱区绿洲农业生态调控有参考价值。",[486],{"name":480,"url":477},[29,488,489,31,490],"土地利用","绿洲农业","生态阈值",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":494},{"candidates":495,"agricultural_evidence":46},[496,500,504,508],{"code":33,"score":218,"supported":46,"title":497,"abstract":498,"tags":499},[],[49,50],[29],{"code":128,"score":107,"supported":46,"title":501,"abstract":502,"tags":503},[],[140,141],[],{"code":60,"score":54,"supported":46,"title":505,"abstract":506,"tags":507},[],[63],[],{"code":71,"score":379,"supported":14,"title":509,"abstract":510,"tags":511},[],[],[488,31],[513,514],"塔里木盆地 沙尘 土地利用","新疆 绿洲 荒漠 遥感","塔里木盆地沙尘土地利用-3897","10.3390\u002Fland15101840",{"doi":516,"openalex_id":518,"authors":519,"venue":480,"cited_by_count":97,"oa_url":477,"card":526,"direction":102,"ingested_from":104},"W7214912709",[520,523],{"name":521,"orcid":522},"Xiaodong Zhang","https:\u002F\u002Forcid.org\u002F0000-0002-9616-9139",{"name":524,"orcid":525},"Yongjun Tang","https:\u002F\u002Forcid.org\u002F0009-0008-2743-5473",{"tldr":527,"method":528,"finding":529,"direction":336,"opportunity":530},"研究塔里木盆地25年土地利用变化与沙尘PM10的耦合关系及阈值效应。","遥感GIS、地理加权回归与分段阈值分析，以乡镇为单元。","裸地与不透水面促尘，耕地呈双刃效应，林草水雪抑尘，绿洲-荒漠过渡带最敏感。","可探究不同作物覆盖与灌溉制度下耕地促尘\u002F抑尘的阈值差异，服务绿洲农业空间优化。","2026-10-01T23:30:28.901978Z"]
