Results indicate that individual remote-sensing indices captured drought processes but reflected different dimensions of drought conditions, with NDVI indicating canopy greenness and LST detecting early thermal stress. Integrated indices partially mitigated the limitations of single indicators during confirmed drought years by showing stronger correlations with reference data. The effectiveness of the integrated indices varied significantly depending on the integration framework. The spatial-normalization–based integration of NDVI and LST showed consistently strong correlations with surface evapotranspiration (ET), with correlation coefficients of approximately 0.8 across years, and was less sensitive to land-cover heterogeneity. In contrast, the triangular NDVI–LST space integration exhibited variable relationships with ET due to its sensitivity to edge definition and phenological shifts in dipterocarp deciduous forests. Phase-dependent behavior was observed, with integrated indices maintaining more stable relationships with ET during drying periods, while NDVI showed greater sensitivity under wetter conditions. The results also indicate that VHI demonstrated a more robust and stable performance than TVDI, suggesting its suitability as a primary indicator in heterogeneous forest environments. These findings provide practical guidance for drought monitoring in heterogeneous forest landscapes by identifying adaptive integration strategies tailored to different hydroclimatic conditions.","本研究考察了归一化差异植被指数（NDVI）、地表温度（LST）及其综合指数在捕捉2014至2024年 Yok Don 国家公园龙脑香落叶林生态系统旱季干旱动态方面的有效性。结果表明，单一遥感指数能够捕捉干旱过程，但反映的是干旱状况的不同维度，其中NDVI指示冠层绿度，LST探测早期热胁迫。综合指数在已确认的干旱年份中通过与参考数据表现出更强的相关性，部分缓解了单一指标的局限性。综合指数的有效性因集成框架的不同而差异显著。基于空间标准化的NDVI与LST集成与地表蒸散发（ET）表现出持续较强的相关性，各年份相关系数约为0.8，且对土地覆盖异质性较不敏感。相比之下，三角NDVI–LST空间集成与ET的关系多变，这是由于其边缘定义及龙脑香落叶林物候变化较为敏感。研究观察到相位依赖行为，综合指数在干旱期与ET保持更稳定的关系，而NDVI在较湿润条件下表现出更高的敏感性。结果还表明，VHI比TVDI表现出更稳健和稳定的性能，表明其适合作为异质森林环境中的主要指标。这些发现通过识别适应不同水文气候条件的自适应集成策略，为异质森林景观的干旱监测提供了实践指导。","Environmental Research Engineering and Management","2026-10-13T00:00:00Z",67,{"impact":17,"substance":18,"depth":19,"authority":89,"freshness":90,"relevant":21,"comment":91},13,9,"越南干旱区遥感监测方法学研究，方法新颖数据扎实，对农业遥感干旱监测有参考价值，但属区域性案例，公共影响有限。",[93],{"name":85,"url":82},[95,27,28,96,29],"农业遥感","干旱监测",[],{"status":33,"locked":14,"version":34,"method":35,"evidence":99},{"candidates":100,"agricultural_evidence":14,"reason":51},[101,108,115],{"code":39,"score":102,"supported":41,"title":103,"abstract":105,"tags":107},15,[104],"drought",[106,104],"干旱",[96],{"code":46,"score":109,"supported":41,"title":110,"abstract":112,"tags":114},14,[111],"remote sensing",[113],"遥感",[27,95,28],{"code":116,"score":77,"supported":41,"title":117,"abstract":118,"tags":121},"H3",[],[119,120],"蒸散发","evapotranspiration",[],[123,124],"Yok Don 国家公园 遥感 干旱","NDVI LST 干旱监测 森林","YokDon国家公园遥感干旱-5012","10.5755\u002Fj01.erem.82.3.44241",{"doi":126,"openalex_id":128,"authors":129,"venue":85,"cited_by_count":66,"oa_url":145,"card":146,"direction":72,"ingested_from":74},"W7221717828",[130,133,136,138,140,142],{"name":131,"orcid":132},"Mai Son Le","https:\u002F\u002Forcid.org\u002F0000-0002-5360-7119",{"name":134,"orcid":135},"Ha Thu Nguyen","https:\u002F\u002Forcid.org\u002F0000-0002-4490-308X",{"name":137,"orcid":9},"Hung Manh Nguyen",{"name":139,"orcid":9},"Huy Xuan Chu",{"name":141,"orcid":9},"Hoa Thanh Nguyen",{"name":143,"orcid":144},"Duy-Toan Dao","https:\u002F\u002Forcid.org\u002F0009-0003-6057-4436","https:\u002F\u002Ferem.ktu.lt\u002Findex.php\u002Ferem\u002Farticle\u002Fdownload\u002F44241\u002F23724",{"tldr":147,"method":148,"finding":149,"direction":72,"opportunity":150},"评估NDVI、LST及其集成指数在越南干旱季风落叶林干旱监测中的效果。","利用2014-2024年NDVI、LST遥感数据，构建空间归一化和三角空间集成指","空间归一化集成指数与ET相关性稳定（约0.8），VHI比TVDI更稳健，集成效果依赖框架。","可探索自适应集成框架在不同水热条件和异质景观下的干旱监测普适性。","2026-10-15T23:30:32.336137Z",{"id":153,"title":154,"url":155,"summary":156,"summary_zh":157,"content":9,"source_name":158,"source_url":155,"published_at":159,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":160,"score_detail":161,"sources":164,"tags":166,"primary_topic":9,"secondary_topics":168,"classification":169,"search_phrases":181,"slug":184,"view_count":21,"doi":185,"paper":186,"created_at":197},4827,"تحليل العلاقة بين الجفاف الموسمي وتناقص الغطاء النباتي واثره في تكرار الظواهر الغبارية في محافظة المثنى للمدة (1980-2025)","https:\u002F\u002Fdoi.org\u002F10.66026\u002Fksfnen31","تعتبر الظواهر الغبارية من الظواهر المناخية التي لها العديد من التأثيرات السلبية على البيئة والاقتصاد والصحة. والغرض من هذه الدراسة التحقق من العلاقة بين تكرار العواصف الرملية والغبار المتطاير والغبار العالق والعوامل المناخية خاصة في المواسم الجافة والرطبة ، وتحليل ودراسة إمكانية حدوث الظواهر الغبارية في منطقة الدراسة وتأثير العوامل المناخية على تكرار حدوثها. اتبعت الدراسة المنهج الوصفي التحليلي، وذلك من خلال الاعتماد على بيانات محطة السماوة المناخية خلال مدة الدراسة من ( 1980- 2025 ) والمحطات الضابطة النجف والديوانية وايضا على بيانات الاستشعار عن بعد الخاصة بالغطاء النباتي الـ NDVI . حيث بينت نتائج الدراسة ان الظروف المناخية تؤثر على التوزيع المكاني للظواهر الغبارية وتكرارها، كما واستخدمت الدراسة معاملات الارتباط لمعالجة البيانات وبيان اتجاه وقوة العلاقة بين الظاهرة المدروسة وأيهما اكثر تأثير من خلال المتغيرات المستقلة والعوامل المناخية المؤثرة فيها. وتوصلت الدراسة إلى ان مصفوفة الارتباط ذات علاقة موجبة قوية بين سرعة الرياح و العاصفة الغبارية أكثر من ارتباطها بأي متغير آخر إذ بلغ معامل الارتباط ( r= 0.79 )، كما ارتبطت إيجابياً بالغبار المتصاعد (r=0.72) والغبار العالق( (r=0.61اما العلاقة الارتباطية بين الرطوبة النسبية والامطار علاقة عك تمثلت منطقة الدراسة بمحافظة المثنى التي تقع في الجزء الجنوبي من العراق يحدها من الشمال محافظة القادسية ومن الشرق محافظتي البصرة وذي قار ومن الغرب محافظة النجف ومن الجنوب المملكة العربية السعودية ، تقع فلكياً بين دائرتي عرض(¢5 29°) ( ¢42 31°) شمالاً وخطي طول (¢50- 43°) و (¢32 -46°)[i] شرقاً كما في الخريطة (1) ، في حين تمثلت المدة الزمنية للظواهر الغبارية من (1980-2025) بالاعتماد على البيانات المناخية لمحطة السماوة و محطة النجف والديوانية كمحطات ضابطة . سية قوية .

and canopy functioning, referred to as vegetation sensitivity, is a crucial measure of drought impacts. While climatic factors influencing vegetation sensitivity are well recognized, the role of phenological shifts remains poorly understood. Using multiple satellite-derived vegetation proxies (NDVI, LAI, SIF, and VOD) during 2001–2021, we show that earlier green-up dates (GUD) exacerbate vegetation sensitivity to flash droughts across 61.2–84.1% of the Northern Hemisphere (>23.5°N). Earlier GUDs enhance pre-drought vegetation growth, especially during the early growing season. Such amplified vegetation growth exacerbates sensitivity by accelerating soil moisture depletion and respiration cost, outweighing the benefit of increased subsequent net carbon assimilation. The contribution of GUD to vegetation sensitivity is comparable to that of major climatic factors. Ignoring phenological changes may lead to underestimation of long-term trends in vegetation sensitivity. These findings underscore the necessity of incorporating the interactions between phenology and flash droughts into projections of ecosystem resistance and resilience. Flash droughts can rapidly reduce vegetation growth, but the role of spring phenology is unclear. The authors show that earlier green-up increases vegetation sensitivity to flash drought across much of the Northern Hemisphere ecosystems.","闪旱导致的植被活动与冠层功能相对下降，即植被敏感性，是衡量干旱影响的关键指标。尽管影响植被敏感性的气候因素已被广泛认识，但物候偏移的作用仍知之甚少。利用2001—2021年多颗卫星衍生的植被代用指标（NDVI、LAI、SIF和VOD），我们发现，在北半球（>23.5°N）61.2%—84.1%的区域，提前的返青期（GUD）加剧了植被对闪旱的敏感性。较早的GUD增强了干旱前的植被生长，尤其是在生长季早期。这种放大的植被生长通过加速土壤水分消耗和呼吸成本加剧了敏感性，其效应超过了随后净碳同化增加带来的益处。GUD对植被敏感性的贡献与主要气候因子相当。忽视物候变化可能导致对植被敏感性长期趋势的低估。这些发现强调了将物候与闪旱之间的相互作用纳入生态系统抵抗力和恢复力预估的必要性。闪旱可迅速降低植被生长，但春季物候的作用尚不清楚。作者表明，在北半球大部分生态系统中，较早的返青增加了植被对闪旱的敏感性。","Nature Communications","2026-10-08T00:00:00Z",86,{"impact":207,"substance":270,"depth":271,"authority":102,"freshness":272,"relevant":21,"comment":273},23,19,7,"基于多源卫星遥感揭示春季提前返青加剧北半球植被对骤发干旱的敏感性，方法扎实、结论新颖，对农业干旱监测预警有参考价值。",[275],{"name":266,"url":263},[26,28,30,277,278],"干旱预警","生态遥感",[],{"status":33,"locked":14,"version":34,"method":35,"evidence":281},{"candidates":282,"agricultural_evidence":14,"reason":51},[283,288,295],{"code":39,"score":284,"supported":41,"title":285,"abstract":286,"tags":287},16,[104],[106,104],[277,26],{"code":289,"score":77,"supported":41,"title":290,"abstract":291,"tags":294},"H2",[],[292,293],"土壤","soil",[],{"code":46,"score":47,"supported":14,"title":296,"abstract":297,"tags":298},[],[],[278,28],[300,301],"北半球 植被 干旱 敏感性","NDVI LAI SIF VOD 遥感","北半球植被干旱敏感性-4590","10.1038\u002Fs41467-026-78296-0",{"doi":303,"openalex_id":305,"authors":306,"venue":266,"cited_by_count":66,"oa_url":330,"card":331,"direction":72,"ingested_from":74},"W7115172292",[307,310,313,316,319,322,324,327],{"name":308,"orcid":309},"Wenrui Bai","https:\u002F\u002Forcid.org\u002F0009-0009-4885-3348",{"name":311,"orcid":312},"Quansheng Ge","https:\u002F\u002Forcid.org\u002F0000-0001-8712-8565",{"name":314,"orcid":315},"Constantin M.

However, the impact of topographic heterogeneity on the nonlinear responses of vegetation to climate change and human activities is not well understood. This gap limits our comprehension of ecosystem resilience. This study focuses on the ecological transition zone of the Qinling–Daba Mountains in China. We utilized 30-m resolution Landsat NDVI data from 2000 to 2022, along with climate, human activity, and topographic data. To characterize vegetation dynamics, we employed Theil–Sen trend analysis, the Mann–Kendall test, and the Hurst index. A Bayesian-optimized XGBoost model, combined with SHAP values, was employed to evaluate the relative contributions and response patterns of potential drivers across various vegetation trend zones and topographic gradients. The analysis revealed a significant greening trend, with the normalized difference vegetation index (NDVI) increasing at a rate of 0.0051 yr. −1 ( p \u003C 0.05). Approximately 90.13% of the region displayed an improving trend, while 89.83% indicated a propensity for continued enhancement. The most pronounced vegetation improvements were observed primarily at moderate elevations (1,750–2,250 m), on moderate slopes (15–20°), and on north-facing slopes. Land use and land cover (LULC) (42.5%), elevation (13.2%), population density (8.2%), and precipitation (7.0%) emerged as the most significant contributors to NDVI predictions across the study area. LULC consistently served as the most influential predictor in both regions experiencing significant increases and those facing declines. In contrast, the relative importance and nonlinear response patterns of other factors varied across different trend zones. These findings provide a scientific foundation for targeted ecological restoration and adaptive vegetation management in ecological transition zones.","生态过渡带被认为是气候敏感区和生物多样性热点区，其植被动态对维持区域生态平衡至关重要。然而，地形异质性如何影响植被对气候变化和人类活动的非线性响应，目前尚不明确。这一空白限制了我们对生态系统恢复力的理解。本研究以中国秦岭—大巴山生态过渡带为对象，利用2000—2022年30 m分辨率的Landsat NDVI数据，并结合气候、人类活动和地形数据。为刻画植被动态，我们采用了Theil–Sen趋势分析、Mann–Kendall检验和Hurst指数。采用贝叶斯优化的XGBoost模型，并结合SHAP值，评估了不同植被趋势区和地形梯度上潜在驱动因子的相对贡献及响应模式。分析揭示出显著的绿化趋势，归一化植被指数（NDVI）以0.0051 yr⁻¹的速率增加（p \u003C 0.05）。约90.13%的区域呈改善趋势，89.83%的区域表现出持续增强的倾向。植被改善最显著的区域主要出现在中等海拔（1,750–2,250 m）、中等坡度（15–20°）和北向坡。土地利用与土地覆盖（LULC）（42.5%）、海拔（13.2%）、人口密度（8.2%）和降水（7.0%）是整个研究区NDVI预测中最重要的贡献因子。在显著增加区和下降区，LULC始终是最具影响力的预测因子。相比之下，其他因素的相对重要性和非线性响应模式在不同趋势区存在差异。这些发现为生态过渡带的针对性生态恢复和适应性植被管理提供了科学依据。","Frontiers in Forests and Global Change","2026-09-28T00:00:00Z",76,{"impact":109,"substance":207,"depth":162,"authority":89,"freshness":90,"relevant":21,"comment":400},"基于30米Landsat NDVI与XGBoost-SHAP量化地形对植被非线性响应的研究，方法新颖、数据扎实，对生态过渡带精准修复有参考价值，但属学术论文，公共传播价值有限。",[402],{"name":396,"url":393},[26,404,27,28,405],"生态修复","植被动态",[],{"status":33,"locked":14,"version":34,"method":35,"evidence":408},{"candidates":409,"agricultural_evidence":14,"reason":51},[410,417,422],{"code":411,"score":272,"supported":41,"title":412,"abstract":413,"tags":416},"H6",[],[414,415],"生物多样性","biodiversity",[404],{"code":39,"score":272,"supported":41,"title":418,"abstract":419,"tags":421},[],[26,420],"climate change",[26],{"code":46,"score":235,"supported":14,"title":423,"abstract":424,"tags":425},[],[],[27,405,28],[427,428],"秦岭大巴山 生态过渡带 植被","NDVI 地形异质性 植被响应","秦岭大巴山生态过渡带植被-3791","10.3389\u002Fffgc.2026.1948232",{"doi":430,"openalex_id":432,"authors":433,"venue":396,"cited_by_count":66,"oa_url":442,"card":443,"direction":72,"ingested_from":74},"W7214562314",[434,436,438,440],{"name":435,"orcid":9},"Xinwen Su",{"name":437,"orcid":9},"Di Wen",{"name":439,"orcid":9},"Jun Li",{"name":441,"orcid":9},"Peng Dailiang","https:\u002F\u002Fwww.frontiersin.org\u002Fjournals\u002Fforests-and-global-change\u002Farticles\u002F10.3389\u002Fffgc.2026.1948232\u002Fpdf",{"tldr":444,"method":445,"finding":446,"direction":72,"opportunity":447},"研究秦岭-大巴山生态过渡带植被非线性响应气候与人类活动，并揭示地形异质性的调控作用。","用2000-2022年30米Landsat NDVI、气候、人类活动和地形数据，","区域显著绿化，NDVI增速0.0051\u002F年；土地利用、海拔、人口密度和降水是主要驱动因子，地形梯度调","可探究其他生态过渡带中地形异质性对植被非线性响应的普适性，并耦合多源遥感与可解释机器学习优化生态修复。","2026-09-29T23:30:28.608664Z"]
