This study evaluated repeated fixed-ground multisensor monitoring at two fixed vegetation scenes in Placerita Canyon, California. Multispectral imaging, radiometric thermal imaging, light detection and ranging (LiDAR), and local atmospheric measurements were integrated across persistent dense, mixed, and dry vegetation regions during 10 quality-controlled visits at a native-chaparral hillside and 24 visits at an oak\u002Fcanopy-centered scene. Persistent vegetation regions remained strongly differentiated across sensing domains while also exhibiting longitudinal change. Dense vegetation exceeded dry vegetation in median normalized difference vegetation index (NDVI) by 0.259 and 0.113 at the two sites, showed 4.11 m and 0.56 m greater LiDAR vertical spread, and remained 3.37 °C and 3.88 °C cooler relative to ambient air. Dense chaparral NDVI declined markedly, while dense, mixed, and dry regions at the oak-centered site showed sustained NDVI declines. Corresponding decreases across three additional spectral indices and spatially differentiated oak-canopy changes showed that the temporal signal extended beyond a single spectral index or whole-canopy average. Multisensor analysis of 96 complete visit × site × region observations showed vegetation region as the dominant source of multivariate separation (partial R² = 0.491, p = 0.0005). By preserving spatial identity while integrating spectral, structural, thermal, and atmospheric measurements, this fixed-ground framework provides a local longitudinal approach for characterizing evolving vegetation and fuel conditions before ignition.","与野火相关的植被和燃料条件通过植被状况、三维燃料结构、热响应和大气干燥度的交互变化而演变，但这些维度通常被分别监测。本研究评估了在加利福尼亚州普莱塞里塔峡谷两个固定植被样地进行的重复固定地面多传感器监测。在10次质量控制的访问中，对本地查帕拉尔灌丛山坡的多光谱成像、辐射热成像、激光雷达（LiDAR）和局地大气测量进行了整合，覆盖了持续存在的密集、混合和干燥植被区域；在24次访问中，对以橡树\u002F冠层为中心的样地进行了同样的整合。持续存在的植被区域在不同传感域之间保持强烈分化，同时也表现出纵向变化。在两个样地中，密集植被的中位归一化差异植被指数（NDVI）分别比干燥植被高0.259和0.113，LiDAR垂直展布分别大4.11 m和0.56 m，并且相对于环境空气分别低3.37 °C和3.88 °C。密集查帕拉尔灌丛的NDVI显著下降，而以橡树为中心的样地中的密集、混合和干燥区域则表现出持续的NDVI下降。另外三个光谱指数的相应下降以及空间分化的橡树冠层变化表明，时间信号超出了单一光谱指数或整个冠层平均值。对96次完整访问×样地×区域观测的多传感器分析表明，植被区域是多变量分离的主导来源（偏R² = 0.491，p = 0.0005）。通过在整合光谱、结构、热和大气测量的同时保持空间身份，这一固定地面框架为表征点火前演变中的植被和燃料条件提供了一种局地纵向方法。",null,"OpenAlex","2026-10-03T00:00:00Z","论文",10,false,69,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},8,22,18,12,9,1,"多传感器固定地面监测方法新颖、数据扎实，对林火燃料与植被状态遥感研究有参考价值，但属基础研究、应用面偏窄。",[25],{"name":10,"url":6},[27,28,29,30,31],"遥感监测","生态监测","森林防火","植被指数","多源遥感",[],{"status":34,"locked":14,"version":35,"method":36,"evidence":37},"needs_review","2026-10-22.2","rules",{"candidates":38,"agricultural_evidence":14,"reason":57},[39,47,52],{"code":40,"score":41,"supported":42,"title":43,"abstract":44,"tags":46},"I3",6,true,[],[45],"multispectral",[31,30,27],{"code":48,"score":22,"supported":14,"title":49,"abstract":50,"tags":51},"H6",[],[],[28],{"code":53,"score":22,"supported":14,"title":54,"abstract":55,"tags":56},"H7",[],[],[29],"农业相关性需要复核",[59,60],"Placerita Canyon 灌丛 橡树 多传感器监测","NDVI LiDAR 热成像 燃料状态","PlaceritaCanyon灌丛橡树多传感器监测-4222","10.31223\u002Fx58r40",{"doi":62,"openalex_id":64,"authors":65,"venue":9,"cited_by_count":68,"oa_url":69,"card":70,"direction":76,"ingested_from":77},"W7218368544",[66],{"name":67,"orcid":9},"Andrew Lee",0,"https:\u002F\u002Feartharxiv.org\u002Frepository\u002Fobject\u002F15343\u002Fdownload\u002F26599\u002F",{"tldr":71,"method":72,"finding":73,"direction":74,"opportunity":75},"固定地面多传感器长期监测南加州灌丛与橡树林，揭示植被与可燃物状态变化。","多光谱、热红外、LiDAR与大气测量，10-24次重复观测两个固定样地。","植被区域是多元分离主因，密集植被NDVI下降且比干燥区更凉、垂直结构更复杂。","农业遥感与作物表型","可扩展至更多生态系统，融合多源时序数据构建可燃物动态预警模型。","智慧农业 \u002F 农业物联网","openalex","2026-10-05T23:30:14.188546Z",{"total":41,"page":22,"page_size":41,"items":80},[81,159,232,290,356,417],{"id":82,"title":83,"url":84,"summary":85,"summary_zh":86,"content":9,"source_name":10,"source_url":84,"published_at":87,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":88,"score_detail":89,"sources":93,"tags":95,"primary_topic":9,"secondary_topics":99,"classification":100,"search_phrases":124,"slug":127,"view_count":22,"doi":128,"paper":129,"created_at":158},5179,"Monitoring Carbon Hotspots in Patchy Landscapes from Sparse Lidar and Dense Satellite Time Series","https:\u002F\u002Fdoi.org\u002F10.31223\u002Fx56j7f","Monitoring aboveground biomass (AGB) stocks as an indicator of carbon storage is essential for climate mitigation, adaptation, and land management. Across much of Earth’s land surface, carbon stocks are concentrated in fine-scale hotspots, including isolated trees in pastures, shrub patches in tundra, and riparian vegetation in drylands. These carbon hotspots are vulnerable to change but are difficult to monitor with remote sensing at broad scales due to three interconnected challenges: (1) spatial heterogeneity, (2) temporal change, and (3) modeling uncertainty. To address these challenges, we developed a workflow that integrates moderate-resolution satellite sensors, aerial lidar collections, and forestry-derived allometric models to produce annual maps of AGB in riparian corridors in the semi-arid western United States. To resolve spatial heterogeneity, we modeled canopy height and vegetation class at 10-m resolution, achieving canopy height mean absolute error of 1.56 m and overall vegetation classification accuracy of 84%. To measure uncertainty, we quantified prediction intervals using conformal prediction for canopy height and classification, ensemble disagreement for epistemic uncertainty, and Bayesian posterior distributions for allometric biomass models. The resulting annual maps provide pixel-level AGB estimates with statistically verified uncertainty bounds. These products reveal gradual changes in riparian biomass and can guide management decisions, from prioritizing restoration efforts to identifying early warning signs of ecosystem degradation. This framework could be adapted for monitoring AGB in other patchy landscapes, incorporated into different or changing land cover categories for future work, and updated as more and better data sources become available.","监测地上生物量（AGB）储量作为碳储量的指标，对于气候减缓、适应和土地管理至关重要。在地球陆地表面的大部分区域，碳储量集中在细尺度热点区域，包括牧场中的孤立树木、苔原中的灌木斑块以及旱地中的河岸植被。这些碳热点易受变化影响，但由于三个相互关联的挑战，难以在广阔尺度上通过遥感进行监测：（1）空间异质性，（2）时间变化，（3）建模不确定性。为应对这些挑战，我们开发了一套工作流程，整合中等分辨率卫星传感器、航空激光雷达采集和林业衍生的异速生长模型，以生成美国西部半干旱地区河岸走廊AGB的年度地图。为解决空间异质性问题，我们在10米分辨率下对冠层高度和植被类别进行建模，实现了冠层高度平均绝对误差1.56米和植被分类总体精度84%。为度量不确定性，我们使用保形预测量化冠层高度和分类的预测区间，使用集成不一致性度量认知不确定性，并使用贝叶斯后验分布构建异速生长生物量模型。由此生成的年度地图提供了具有统计验证不确定性边界的像素级AGB估算。这些产品揭示了河岸生物量的渐进变化，并可指导管理决策，从优先安排恢复工作到识别生态系统退化的早期预警信号。该框架可适用于监测其他斑块状景观中的AGB，可纳入未来工作中不同或变化的土地覆盖类别，并可随着更多更好的数据源的出现而更新。","2026-10-15T00:00:00Z",73,{"impact":20,"substance":90,"depth":19,"authority":91,"freshness":21,"relevant":22,"comment":92},21,13,"方法新颖、不确定性量化扎实，但属区域尺度遥感论文，对农业信息化有间接参考价值，未达每日精选门槛。",[94],{"name":10,"url":84},[27,28,96,97,98],"生物量估算","碳储量","激光雷达",[],{"status":34,"locked":14,"version":35,"method":36,"evidence":101},{"candidates":102,"agricultural_evidence":14,"reason":57},[103,109,115,120],{"code":40,"score":17,"supported":42,"title":104,"abstract":105,"tags":108},[],[106,107],"遥感","remote sensing",[96,27],{"code":53,"score":110,"supported":42,"title":111,"abstract":112,"tags":114},3,[],[113],"干旱",[],{"code":116,"score":22,"supported":14,"title":117,"abstract":118,"tags":119},"H4",[],[],[97],{"code":48,"score":22,"supported":14,"title":121,"abstract":122,"tags":123},[],[],[28],[125,126],"稀疏激光雷达 卫星时序 生物量","河岸带 碳热点 遥感监测","稀疏激光雷达卫星时序生物量-5179","10.31223\u002Fx56j7f",{"doi":128,"openalex_id":130,"authors":131,"venue":9,"cited_by_count":68,"oa_url":152,"card":153,"direction":74,"ingested_from":77},"W7222218373",[132,135,137,139,141,143,145,148,150],{"name":133,"orcid":134},"Erik Nati‐Johnson","https:\u002F\u002Forcid.org\u002F0009-0009-3923-4115",{"name":136,"orcid":9},"Jodi Brandt",{"name":138,"orcid":9},"Nicholas Kolarik",{"name":140,"orcid":9},"Rose Graves",{"name":142,"orcid":9},"Anand Roopsind",{"name":144,"orcid":9},"Marie-Anne de Graff",{"name":146,"orcid":147},"Juan Camilo Rojas Lucero","https:\u002F\u002Forcid.org\u002F0009-0004-4934-3108",{"name":149,"orcid":9},"Colin Martin",{"name":151,"orcid":9},"Trevor Caughlin","https:\u002F\u002Feartharxiv.org\u002Frepository\u002Fobject\u002F15555\u002Fdownload\u002F26955\u002F",{"tldr":154,"method":155,"finding":156,"direction":74,"opportunity":157},"融合稀疏激光雷达与密集卫星时序，绘制半干旱河岸带地上生物量年度图。","中分辨率卫星、航空激光雷达与异速生长模型，结合共形预测与贝叶斯不确定性量化。","10米分辨率冠层高度误差1.56米、分类精度84%，可检测河岸生物量渐变。","可将该框架迁移至农田防护林、零星树木等破碎景观碳热点监测，并融合更高分辨率数据。","2026-10-17T23:30:31.577923Z",{"id":160,"title":161,"url":162,"summary":163,"summary_zh":164,"content":9,"source_name":165,"source_url":162,"published_at":166,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":167,"score_detail":168,"sources":171,"tags":173,"primary_topic":177,"secondary_topics":182,"classification":188,"search_phrases":203,"slug":206,"view_count":68,"doi":207,"paper":208,"created_at":231},4826,"Multi-Index Remote Sensing Assessment of Agro-Climatic Change and Agricultural Responses in Temperate and Semi-Arid Regions","https:\u002F\u002Fdoi.org\u002F10.3390\u002Frs18203496","Diverse climatic regions exhibit unique agro-climatic vulnerabilities that are significantly shaped by climate stress. Understanding these distinct vulnerabilities is essential for developing effective policies to mitigate climate change impacts and ensuring sustainable environmental management. This study examines agro-climatic vulnerabilities in Nottinghamshire County (United Kingdom) and Udaipur District (India) from 2000 to 2024, comparing climate change impacts across temperate and semi-arid agricultural systems that represent fundamentally different system behaviours under contrasting climatic conditions. Using multi-temporal Landsat imagery and WorldClim climate data, nine environmental indices were analysed: the Normalized Difference Vegetation Index (NDVI), Vegetation Condition Index (VCI), Normalized Difference Water Index (NDWI), Moisture Stress Index (MSI), Land Surface Temperature (LST), Temperature Condition Index (TCI), Vegetation Health Index (VHI), Drought Risk Index (DRI), and Crop Health Index (CHI). The results reveal contrasting regional trajectories that challenge conventional assumptions about climate vulnerability. Udaipur exhibited improved vegetation and moisture conditions across the observation period, whereas Nottinghamshire showed intensifying moisture stress and declining precipitation. Warming was more pronounced in Nottinghamshire, while strong inter-index correlations validated the monitoring approach. These findings indicate that Udaipur benefits from intensified monsoon patterns, requiring flood mitigation and water-storage infrastructure, whereas Nottinghamshire’s rising moisture stress underscores the need for sustained monitoring and adaptive management. This comparative framework provides evidence-based insights for region-specific adaptation strategies essential to sustainable agricultural development across diverse agro-climatic zones.","不同气候区域表现出独特的农业气候脆弱性，而这些脆弱性在很大程度上受到气候胁迫的影响。理解这些不同的脆弱性对于制定有效政策以减缓气候变化影响、确保可持续环境管理至关重要。本研究考察了2000年至2024年间英国诺丁汉郡与印度乌代布尔县的农业气候脆弱性，比较了温带与半干旱农业系统在气候变化影响下的差异，这两类系统在截然不同的气候条件下代表了根本不同的系统行为。研究利用多时相Landsat影像和WorldClim气候数据，分析了九个环境指数：归一化植被指数（NDVI）、植被状态指数（VCI）、归一化水体指数（NDWI）、水分胁迫指数（MSI）、地表温度（LST）、温度状态指数（TCI）、植被健康指数（VHI）、干旱风险指数（DRI）和作物健康指数（CHI）。结果揭示了截然不同的区域变化轨迹，挑战了关于气候脆弱性的传统假设。乌代布尔在观测期内表现出植被和水分条件的改善，而诺丁汉郡则显示出加剧的水分胁迫和降水减少。诺丁汉郡的增温更为显著，而指数间较强的相关性验证了该监测方法。这些发现表明，乌代布尔受益于季风模式的增强，需要防洪和水储存基础设施，而诺丁汉郡不断上升的水分胁迫则凸显了持续监测和适应性管理的必要性。这一比较框架为因地制宜的适应策略提供了循证依据，对跨不同农业气候区的可持续发展至关重要。","Remote Sensing","2026-10-12T00:00:00Z",75,{"impact":20,"substance":18,"depth":19,"authority":169,"freshness":21,"relevant":22,"comment":170},14,"基于多时相遥感与九项环境指数的跨区域对比研究，方法扎实、结论具政策参考价值，但属学术论文，产业影响有限。",[172],{"name":165,"url":162},[27,30,174,175,176],"干旱风险","适应策略","农业气候",{"code":40,"slug":178,"name":179,"path":180,"parent_code":181},"remote-sensing","遥感与农情监测","\u002Ftopic\u002Fdigital-agriculture\u002Fremote-sensing","I",[183],{"code":53,"slug":184,"name":185,"path":186,"parent_code":187},"climate","气候适应与防灾减灾","\u002Ftopic\u002Fenvironment\u002Fclimate","H",{"status":189,"locked":14,"version":35,"method":36,"evidence":190},"classified",{"candidates":191,"agricultural_evidence":42},[192,196],{"code":40,"score":13,"supported":42,"title":193,"abstract":194,"tags":195},[107],[],[30,27],{"code":53,"score":21,"supported":42,"title":197,"abstract":198,"tags":202},[],[199,113,200,201],"气候变化","climate change","drought",[],[204,205],"Landsat 遥感 农业气候","诺丁汉郡 乌代布尔","Landsat遥感农业气候-4826","10.3390\u002Frs18203496",{"doi":207,"openalex_id":209,"authors":210,"venue":165,"cited_by_count":68,"oa_url":162,"card":226,"direction":74,"ingested_from":77},"W7221570035",[211,214,217,220,223],{"name":212,"orcid":213},"Bhanwar Vishvendra Raj Singh","https:\u002F\u002Forcid.org\u002F0000-0001-7750-5240",{"name":215,"orcid":216},"Vivek Agarwal","https:\u002F\u002Forcid.org\u002F0000-0003-1185-3802",{"name":218,"orcid":219},"Stuart Marsh","https:\u002F\u002Forcid.org\u002F0000-0002-1168-6760",{"name":221,"orcid":222},"Gajendra Singh Sisodiya","https:\u002F\u002Forcid.org\u002F0009-0006-4118-7491",{"name":224,"orcid":225},"Ajay Sharma","https:\u002F\u002Forcid.org\u002F0009-0001-6077-9875",{"tldr":227,"method":228,"finding":229,"direction":74,"opportunity":230},"用多时相遥感和九项指数对比英国诺丁汉郡与印度乌代浦2000—2024年农业气候脆弱性。","Landsat多时相影像与WorldClim气候数据，计算NDVI、VCI、ND","乌代浦植被与水分条件改善、季风增强，诺丁汉郡水分胁迫加剧、降水下降且升温更明显。","可拓展多区域长时序遥感指数耦合机器学习，构建跨气候带农业气候脆弱性预警与适应决策模型。","2026-10-13T23:30:24.062929Z",{"id":233,"title":234,"url":235,"summary":236,"summary_zh":237,"content":9,"source_name":238,"source_url":235,"published_at":166,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":239,"score_detail":240,"sources":242,"tags":244,"primary_topic":9,"secondary_topics":248,"classification":249,"search_phrases":266,"slug":269,"view_count":68,"doi":270,"paper":271,"created_at":289},4823,"Comparing Sentinel-2 Spectral Indices for Mapping Forest Fire Damage in Pollino National Park, Italy","https:\u002F\u002Fdoi.org\u002F10.5194\u002Fisprs-archives-xlviii-m-13-2026-1-2026","In recent years, climate change has significantly increased the severity and frequency of wildfires across Europe, with the 2025 season marking an unprecedented peak of one million hectares burned.

The results indicate that the years 2003, 2008, and 2018 experienced the most severe droughts, as shown consistently across all indices. Spatial analysis revealed that the central, southern, and eastern lowland areas faced the highest frequency and severity of drought, while the northwestern highlands remained comparatively resilient. Cross‐index correlation revealed strong agreement between SPI and VCI ( R 2 = 0.77), and between VHI and VCI ( R 2 = 0.83), supporting the effectiveness of integrated drought monitoring approaches. This research advances the field of drought assessment by enhancing spatial and temporal resolution and validating cross‐index relationships at the subregional level. The results provide critical insights for localized drought early warning systems, climate adaptation strategies, and future research to improve agricultural resilience under changing climatic conditions. Hence, agricultural drought risk mapping serves as a valuable tool for guiding decision‐making in drought monitoring and for mitigating its impacts on agricultural productivity.","摘要 农业干旱严重威胁粮食安全、生计和生态系统稳定性，尤其是在东巴莱区等易旱地区。本研究结合气象站数据与卫星反演的植被和热力指数，探讨了30年（1993—2024年）间农业干旱的时空格局。为评估气象干旱，计算了3个月、6个月和12个月尺度的标准化降水指数（SPI）。在农业与热胁迫分析方面，采用了基于遥感的植被状态指数（VCI）、温度状态指数和植被健康指数（VHI）。结果表明，2003年、2008年和2018年经历了最严重的干旱，各指数均一致反映了这一情况。空间分析显示，中部、南部和东部低地地区干旱发生频率最高、程度最严重，而西北部高地则相对具有较强恢复力。跨指数相关性分析表明，SPI与VCI之间（R²=0.77）以及VHI与VCI之间（R²=0.83）具有高度一致性，支持了综合干旱监测方法的有效性。本研究通过提高时空分辨率并在次区域尺度上验证跨指数关系，推进了干旱评估领域的发展。研究结果为地方性干旱预警系统、气候适应策略以及未来研究提供了重要见解，有助于在气候变化条件下提升农业韧性。因此，农业干旱风险制图为干旱监测决策及其对农业生产影响的减缓提供了有价值的工具。","Agrosystems Geosciences & Environment","2026-10-11T00:00:00Z",68,{"impact":17,"substance":90,"depth":300,"authority":91,"freshness":21,"relevant":22,"comment":301},17,"基于30年气象与遥感指数交叉验证的农业干旱时空制图研究，方法扎实、结论可靠，但属区域性案例，对国内三农信息化仅有方法借鉴价值。",[303],{"name":296,"url":293},[305,306,27,30,307],"粮食安全","防灾减灾","农业干旱",{"code":53,"slug":184,"name":185,"path":186,"parent_code":187},[310],{"code":40,"slug":178,"name":179,"path":180,"parent_code":181},{"status":189,"locked":14,"version":35,"method":36,"evidence":312},{"candidates":313,"agricultural_evidence":42},[314,319,323,330],{"code":53,"score":19,"supported":42,"title":315,"abstract":316,"tags":318},[201],[199,317,113,201],"气候适应",[306],{"code":40,"score":17,"supported":42,"title":320,"abstract":321,"tags":322},[],[106,107],[30,27],{"code":324,"score":325,"supported":42,"title":326,"abstract":327,"tags":329},"A8",7,[],[305,328],"food security",[305],{"code":331,"score":41,"supported":42,"title":332,"abstract":333,"tags":336},"I4",[],[334,335],"空间分析","spatial analysis",[],[338,339],"埃塞俄比亚 East Bale 农业干旱","SPI VCI 干旱监测","埃塞俄比亚EastBale农业干旱-4747","10.1002\u002Fagg2.70475",{"doi":341,"openalex_id":343,"authors":344,"venue":296,"cited_by_count":68,"oa_url":293,"card":350,"direction":74,"ingested_from":77},"W7221455809",[345,347],{"name":346,"orcid":9},"Murad Hedo Haji",{"name":348,"orcid":349},"Karuturi Venkata Suryabhagavan","https:\u002F\u002Forcid.org\u002F0000-0003-2528-9106",{"tldr":351,"method":352,"finding":353,"direction":74,"opportunity":354},"结合气象站与卫星植被热指数，绘制埃塞俄比亚East Bale区30年农业干旱时空图。","用SPI（3\u002F6\u002F12月）与遥感VCI、TCI、VHI指数做交叉相关分析。","2003、2008、2018年干旱最重，中南部和东部低地最脆弱，SPI与VCI相关性R²=0.77。","可在小区域尺度融合多源指数构建干旱预警模型，并验证指数在不同作物区的适用性。","2026-10-12T23:30:24.342375Z",{"id":357,"title":358,"url":359,"summary":360,"summary_zh":361,"content":9,"source_name":362,"source_url":359,"published_at":363,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":364,"score_detail":365,"sources":369,"tags":371,"primary_topic":9,"secondary_topics":374,"classification":375,"search_phrases":391,"slug":394,"view_count":22,"doi":395,"paper":396,"created_at":416},4582,"Assessing mangrove sensitivity to thermal variations through a satellite-based analysis on the southern São Paulo coast, Brazil","https:\u002F\u002Fdoi.org\u002F10.1007\u002Fs10661-026-16005-6","Abstract Mangroves near subtropical range limits may benefit from fewer cold constraints, yet warmer conditions can also increase atmospheric water demand. These competing possibilities were examined in the Cananéia-Iguape Coastal System, southeastern Brazil, by combining ERA5 2 m air temperature with MODIS normalized difference vegetation index (NDVI), enhanced vegetation index (EVI), and leaf area index (LAI). Air-temperature trends were assessed for 1979–2019 with the Mann-Kendall test and Sen’s slope. Temperature-vegetation associations were calculated for 2003–2019 from mangrove-wide means and from individual grid cells at annual, monthly, and fixed calendar-quarter scales. Mean annual air temperature increased by about 0.02 °C year⁻ 1 ; the highest quarter-scale rate occurred in July–September (0.03 °C year⁻ 1 ). Annual temperature correlated positively with NDVI ( r = 0.61, R 2 = 0.38, p = 0.009) and EVI ( r = 0.55, R 2 = 0.30, p = 0.022), whereas the LAI relationship was not significant ( r = 0.27, R 2 = 0.07, p = 0.304). The sign of the association changed within the year: NDVI and EVI were negative in July–September, while positive EVI and LAI relationships occurred in October-December. Significant grid-cell relationships occupied limited and discontinuous areas. The temperature record shows regional warming, whereas canopy associations vary among metrics, periods, and locations. Given the bivariate design and coarse ERA5 grid, these associations should not be interpreted as causal or as responses to temperature alone.","摘要 靠近亚热带分布界限的红树林可能受益于较少的低温限制，但更温暖的条件也可能增加大气水分需求。为检验这两种相互竞争的的可能性，本研究在巴西东南部的卡纳内亚-伊瓜佩海岸系统，将ERA5 2米气温数据与MODIS归一化差异植被指数（NDVI）、增强植被指数（EVI）和叶面积指数（LAI）相结合进行了分析。采用Mann-Kendall检验和Sen斜率法评估了1979—2019年的气温趋势。基于2003—2019年红树林全域均值及单个网格单元，在年、月和固定日历季度尺度上计算了气温-植被关联。年平均气温上升约0.02 °C yr⁻¹；季度尺度最高升温速率出现在7—9月（0.03 °C yr⁻¹）。年气温与NDVI呈正相关（r = 0.61，R² = 0.38，p = 0.009），与EVI也呈正相关（r = 0.55，R² = 0.30，p = 0.022），而与LAI的关系不显著（r = 0.27，R² = 0.07，p = 0.304）。关联方向在年内发生变化：NDVI和EVI在7—9月为负，而EVI和LAI的正相关关系出现在10—12月。显著的网格单元关系占据有限且不连续的区域。气温记录显示区域变暖，而冠层关联因指标、时段和地点而异。鉴于双变量设计和ERA5网格较粗，这些关联不应被解释为因果关系或仅对温度的响应。","Environmental Monitoring and Assessment","2026-10-09T00:00:00Z",66,{"impact":17,"substance":366,"depth":367,"authority":91,"freshness":21,"relevant":22,"comment":368},20,16,"方法规范、结论审慎的区域性遥感研究，对农业信息化中的生态遥感监测有参考价值，但影响范围限于学术层面。",[370],{"name":362,"url":359},[199,27,30,372,373],"红树林","海岸带生态",[],{"status":34,"locked":14,"version":35,"method":36,"evidence":376},{"candidates":377,"agricultural_evidence":14,"reason":57},[378,383,387],{"code":40,"score":379,"supported":14,"title":380,"abstract":381,"tags":382},2,[],[],[30,27],{"code":48,"score":22,"supported":14,"title":384,"abstract":385,"tags":386},[],[],[372],{"code":53,"score":22,"supported":14,"title":388,"abstract":389,"tags":390},[],[],[199],[392,393],"巴西 圣保罗 红树林 遥感","MODIS NDVI 红树林 温度","巴西圣保罗红树林遥感-4582","10.1007\u002Fs10661-026-16005-6",{"doi":395,"openalex_id":397,"authors":398,"venue":362,"cited_by_count":68,"oa_url":410,"card":411,"direction":74,"ingested_from":77},"W7220983448",[399,402,405,407],{"name":400,"orcid":401},"Jakeline Baratto","https:\u002F\u002Forcid.org\u002F0000-0003-0311-2369",{"name":403,"orcid":404},"Paulo Miguel De Bodas Terassi","https:\u002F\u002Forcid.org\u002F0000-0002-8184-0348",{"name":406,"orcid":9},"Nádia Gilma Beserra de Lima",{"name":408,"orcid":409},"Emerson Galvani","https:\u002F\u002Forcid.org\u002F0000-0002-8082-5963","https:\u002F\u002Flink.springer.com\u002Fcontent\u002Fpdf\u002F10.1007\u002Fs10661-026-16005-6.pdf",{"tldr":412,"method":413,"finding":414,"direction":74,"opportunity":415},"结合气温与植被指数分析巴西东南部红树林对温度变化的敏感性。","ERA5气温与MODIS NDVI\u002FEVI\u002FLAI，用Mann-Kendall趋","区域增温，但植被与温度关联随指标、时段和地点变化，非因果。","可引入多源遥感与因果推断，探究亚热带红树林对增温的滞后与非线性响应。","2026-10-10T23:30:27.692383Z",{"id":418,"title":419,"url":420,"summary":421,"summary_zh":422,"content":9,"source_name":423,"source_url":420,"published_at":424,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":298,"score_detail":425,"sources":427,"tags":429,"primary_topic":9,"secondary_topics":433,"classification":434,"search_phrases":454,"slug":457,"view_count":325,"doi":458,"paper":459,"created_at":486},4436,"Tracing the invisible footprint of mining in Iran: spectral mapping of heavy metal contamination in arid soils with a remote sensing approach","https:\u002F\u002Fdoi.org\u002F10.1007\u002Fs12518-026-00809-9","This research applies an interdisciplinary framework to investigate the interactions between mining activities, heavy metal contamination, and vegetation response in the Sangan mining areas of Khaf County, Iran. Geochemical analyses of 24 surface soil samples were integrated with remote sensing data from Landsat 8-OLI to develop a robust methodology for monitoring stressed ecosystems. Chemical analysis revealed substantial accumulation of cadmium (Cd, barium (Ba) and arsenic (As). The mean Cd concentration (26.5 mg kg⁻¹) was about 88 times higher than the global shale average (0.3 mg kg⁻¹), which is likely associated with to intensive iron ore mining. This finding underscores the risk of these metals entering the food chain and threatening human health, especially in children, who exhibit higher absorption rates. From a remote-sensing perspective, soil-adjusted vegetation indices such as RVI ( R = 0.82) and MSAVI2 ( R = 0.79) outperformed NDVI ( R = 0.40) in arid environments with sparse vegetation, providing a methodological advance for ecological monitoring. Correlation analyses between heavy metals and vegetation indices revealed a strong negative association between copper (Cu) and most indices, particularly IPVI ( R = − 0.69), indicating copper’s phytotoxic effects on chlorophyll and biomass. In contrast, chromium (Cr) showed a weak positive correlation with NDVI ( R = 0.36). These results highlight the need to select vegetation indices according to local environmental conditions and offer a practical framework for enhancing remote sensing–based monitoring of contaminated ecosystems. The study improves understanding of mining impacts and provides a replicable model for sustainable management of mining-affected landscapes worldwide.","本研究采用跨学科框架，探讨伊朗哈夫县桑甘矿区采矿活动、重金属污染与植被响应之间的相互作用。研究将24个表层土壤样品的地球化学分析与Landsat 8-OLI遥感数据相结合，构建了一套用于监测受胁迫生态系统的稳健方法。化学分析显示，镉（Cd）、钡（Ba）和砷（As）显著累积。镉的平均浓度（26.5 mg kg⁻¹）约为全球页岩平均值（0.3 mg kg⁻¹）的88倍，这很可能与密集的铁矿石开采有关。该发现凸显了这些金属进入食物链并威胁人体健康的风险，尤其是对吸收率更高的儿童而言。从遥感角度看，在植被稀疏的干旱环境中，土壤调节植被指数如RVI（R = 0.82）和MSAVI2（R = 0.79）优于NDVI（R = 0.40），为生态监测提供了方法学进展。重金属与植被指数之间的相关分析显示，铜（Cu）与大多数指数呈强负相关，尤其是与IPVI（R = −0.69），表明铜对叶绿素和生物量具有植物毒性效应。相比之下，铬（Cr）与NDVI呈弱正相关（R = 0.36）。这些结果凸显了根据当地环境条件选择植被指数的必要性，并为加强基于遥感的污染生态系统监测提供了实用框架。该研究增进了对采矿影响的理解，并为全球受采矿影响景观的可持续管理提供了一个可复制的模型。","Applied Geomatics","2026-10-07T00:00:00Z",{"impact":17,"substance":90,"depth":300,"authority":91,"freshness":21,"relevant":22,"comment":426},"方法新颖、数据扎实的矿区土壤重金属遥感监测研究，对农业生态与耕地污染监测有借鉴价值，但属境外案例、影响范围有限。",[428],{"name":423,"url":420},[27,430,30,431,432],"矿区生态","土壤修复","重金属污染",[],{"status":34,"locked":14,"version":35,"method":36,"evidence":435},{"candidates":436,"agricultural_evidence":14,"reason":57},[437,441,446,450],{"code":40,"score":367,"supported":42,"title":438,"abstract":439,"tags":440},[107],[106,107],[30,27],{"code":261,"score":17,"supported":42,"title":442,"abstract":443,"tags":445},[],[444,264],"土壤",[431,432],{"code":53,"score":110,"supported":42,"title":447,"abstract":448,"tags":449},[],[113],[],{"code":48,"score":22,"supported":14,"title":451,"abstract":452,"tags":453},[],[],[430],[455,456],"伊朗 Sangan 矿区 重金属","Landsat 8 OLI 植被指数","伊朗Sangan矿区重金属-4436","10.1007\u002Fs12518-026-00809-9",{"doi":458,"openalex_id":460,"authors":461,"venue":423,"cited_by_count":68,"oa_url":480,"card":481,"direction":74,"ingested_from":77},"W7220854014",[462,465,468,471,474,477],{"name":463,"orcid":464},"Javad Momeni Damaneh","https:\u002F\u002Forcid.org\u002F0009-0006-9131-6167",{"name":466,"orcid":467},"E Tamassoki","https:\u002F\u002Forcid.org\u002F0000-0002-9873-1957",{"name":469,"orcid":470},"Mohammed Achite","https:\u002F\u002Forcid.org\u002F0000-0001-6084-5759",{"name":472,"orcid":473},"Seyed Mohammad Tajbakhsh","https:\u002F\u002Forcid.org\u002F0000-0002-2097-9944",{"name":475,"orcid":476},"Kusum Pandey","https:\u002F\u002Forcid.org\u002F0009-0005-4888-6650",{"name":478,"orcid":479},"Celso Augusto Guimarães Santos","https:\u002F\u002Forcid.org\u002F0000-0001-7927-9718","https:\u002F\u002Flink.springer.com\u002Fcontent\u002Fpdf\u002F10.1007\u002Fs12518-026-00809-9.pdf",{"tldr":482,"method":483,"finding":484,"direction":74,"opportunity":485},"结合土壤地球化学与Landsat 8遥感，绘制伊朗干旱矿区重金属污染与植被胁迫图谱。","24个表层土壤样地球化学分析，结合Landsat 8-OLI植被指数与相关性分析","Cd超标88倍；RVI、MSAVI2优于NDVI，Cu与植被指数强负相关。","干旱稀疏植被区需筛选适宜植被指数，可发展重金属胁迫遥感反演与食物链风险预警模型。","2026-10-08T23:30:29.578924Z"]
