This study develops a robust machine-learning framework to map Boro rice in the Manikganj district by integrating Sentinel-1 Synthetic Aperture Radar (SAR) and Sentinel-2 optical imagery. To overcome the challenge of seasonal cloud cover, Sentinel-1 VH polarization was utilized to identify unique backscatter reductions during the transplantation phase (late February to early March) caused by specular reflection from flooded fields. By combining these SAR signatures with high-resolution spectral indices (NDVI, EVI, and BSI) from Sentinel-2 during peak growth stages, the research captures the distinct phenological signatures of paddy rice. A pixel-based Random Forest algorithm was applied within the Google Earth Engine (GEE) platform, utilizing about 200 field-verified reference points per sub-district (1,385 in total) for training and validation. The results demonstrated high classification performance, with overall accuracies ranging from 88.1% to 94.9% across the seven sub-districts. Furthermore, a comparison with official government statistics revealed a minimal total area difference of only 2.34%, underscoring the reliability of this integrated satellite approach for operational crop monitoring.","准确的当季作物制图对国家粮食安全至关重要，然而孟加拉国传统的基于地面估计的方法往往缺乏精度。本研究开发了一个稳健的机器学习框架，通过整合Sentinel-1合成孔径雷达（SAR）和Sentinel-2光学影像，对马尼格甘杰县的Boro水稻进行制图。为克服季节性云覆盖的挑战，研究利用Sentinel-1 VH极化识别插秧期（2月下旬至3月上旬）由淹水田块镜面反射所引起的独特后向散射降低特征。通过将这些SAR特征与Sentinel-2在生长旺盛期的高分辨率光谱指数（NDVI、EVI和BSI）相结合，研究捕捉到了水稻独特的物候特征。在Google Earth Engine（GEE）平台上应用了基于像元的随机森林算法，利用每个乡约200个实地验证参考点（共计1，385个）进行训练和验证。结果表明分类性能较高，七个乡的总体精度在88.1%至94.9%之间。此外，与政府官方统计数据相比，总面积差异仅为2.34%，凸显了这种综合卫星方法在业务化作物监测中的可靠性。",null,"OpenAlex","2026-10-18T00:00:00Z","论文",10,false,79,{"impact":17,"substance":18,"depth":17,"authority":19,"freshness":20,"relevant":21,"comment":22},18,22,12,9,1,"方法扎实、精度可靠的水稻遥感制图研究，对农业遥感业务化监测有参考价值，但属区域性案例，影响层级有限。",[24],{"name":10,"url":6},[26,27,28,29,30],"水稻","粮食安全","机器学习","作物制图","遥感",{"code":32,"slug":33,"name":26,"path":34,"parent_code":35},"A1","rice","\u002Ftopic\u002Ffield-crops\u002Frice","A",[],{"status":38,"locked":14,"version":39,"method":40,"evidence":41},"classified","2026-10-22.2","rules",{"candidates":42,"agricultural_evidence":44},[43,49,56,62],{"code":32,"score":17,"supported":44,"title":45,"abstract":46,"tags":48},true,[33],[26,33,47],"paddy",[26],{"code":50,"score":51,"supported":44,"title":52,"abstract":53,"tags":55},"A8",7,[],[27,54],"food security",[27],{"code":57,"score":58,"supported":44,"title":59,"abstract":60,"tags":61},"I2",4,[],[28],[28],{"code":63,"score":21,"supported":14,"title":64,"abstract":65,"tags":66},"I3",[],[],[30],[68,69],"Sentinel-1 Sentinel-2 水稻制图","孟加拉国 Boro 水稻 遥感","Sentinel-1Sentinel-2水稻制图-5319",0,"10.31223\u002Fx5f22w",{"doi":72,"openalex_id":74,"authors":75,"venue":9,"cited_by_count":71,"oa_url":88,"card":89,"direction":93,"ingested_from":95},"W7222810209",[76,78,81,84,86],{"name":77,"orcid":9},"Mst.

In this study, we developed a high-precision mapping framework for major rice cropping patterns in the Yangtze River Delta region, China, using the Google Earth Engine (GEE) cloud platform. A multi-temporal and multi-source feature set was constructed by integrating Sentinel-1 radar backscatter (VV\u002FVH polarization), Sentinel-2 optical indices, including the normalized difference vegetation index (NDVI) and land surface water index (LSWI), and topographic factors (DEM and slope), to classify three predominant cropping systems, namely, wheat–rice rotation, double rice, and rapeseed–rice rotation. A total of 548 field-surveyed sample points collected during the 2024–2025 growing season were used for model training and validation. Three classical classifiers—Random Forest (RF), A Gradient Boosting Tree (GBTREE), and a Support Vector Machine (SVM)—were systematically compared. The ablation experiment demonstrated that the fusion of Sentinel-1 and Sentinel-2 outperformed both the Sentinel-1-only and Sentinel-2-only configurations across all three classifiers. Among them, the GBTREE achieved the highest overall accuracy (93.8%), Kappa coefficient (0.87), and macro-average F1 score (88.3%) in this specific experiment. Notably, it also performed best on the more challenging double-rice class. The SHapley Additive exPlanations (SHAP)-based feature importance analysis revealed that multi-temporal NDVI phenological features were the primary drivers of classification accuracy, while radar backscatter and water indices provided essential complementary information, and topographic factors served as spatial constraints at the regional scale. The spatial distribution derived from the GBTREE classification exhibited clear patterns: wheat–rice rotation dominated the northern plains (northern Jiangsu, northern Anhui, and the Hangjiahu Plain); double rice was concentrated in the southern Zhejiang hills and scattered valley plains; and rapeseed–rice rotation showed a scattered, mosaic distribution. Overall, this study demonstrates that integrating multi-source remote sensing data on the GEE platform with the GBTREE classifier enables effective and scalable high-precision mapping of rice cropping patterns in complex agricultural landscapes. This approach provides a reliable technical foundation for regional agricultural structure analysis, crop rotation assessment, and sustainable agricultural monitoring.","准确绘制水稻种植模式图是实现可持续农业管理和区域粮食安全评估的基础。本研究基于Google Earth Engine（GEE）云平台，构建了长江三角洲地区主要水稻种植模式的高精度制图框架。通过整合Sentinel-1雷达后向散射（VV\u002FVH极化）、Sentinel-2光学指数（包括归一化差异植被指数NDVI和地表水体指数LSWI）以及地形因子（DEM和坡度），构建了多时相、多源特征集，用于分类三种主要种植制度，即麦–稻轮作、双季稻和油–稻轮作。利用2024—2025年生长季采集的548个实地调查样点进行模型训练与验证。系统比较了三种经典分类器——随机森林（RF）、梯度提升树（GBTREE）和支持向量机（SVM）。消融实验表明，Sentinel-1与Sentinel-2的融合在三种分类器中均优于仅使用Sentinel-1或仅使用Sentinel-2的配置。其中，GBTREE在本实验中取得了最高的总体精度（93.8%）、Kappa系数（0.87）和宏平均F1分数（88.3%）。值得注意的是，其在更具挑战性的双季稻类别上同样表现最佳。基于SHapley加法解释（SHAP）的特征重要性分析表明，多时相NDVI物候特征是分类精度的主要驱动因素，雷达后向散射和水体指数提供了必要的补充信息，而地形因子则在区域尺度上起到空间约束作用。基于GBTREE分类得到的空间分布呈现出清晰的格局：麦–稻轮作主导北部平原（苏北、皖北和杭嘉湖平原）；双季稻集中于浙南丘陵和零散的河谷平原；油–稻轮作则呈零散镶嵌状分布。总体而言，本研究表明，在GEE平台上整合多源遥感数据与GBTREE分类器，能够对复杂农业景观中的水稻种植模式进行有效且可扩展的高精度制图。该方法为区域农业结构分析和作物","Remote Sensing","2026-09-24T00:00:00Z",{"impact":109,"substance":18,"depth":17,"authority":110,"freshness":20,"relevant":21,"comment":111},16,14,"基于GEE与Sentinel-1\u002F2时序影像结合机器学习实现长三角水稻种植模式高精度制图，方法扎实、结论可靠，对农业遥感监测有参考价值。",[113],{"name":106,"url":103},[115,26,28,30,116],"智慧农业","作物分类",{"code":32,"slug":33,"name":26,"path":34,"parent_code":35},[119,124],{"code":57,"slug":120,"name":121,"path":122,"parent_code":123},"agricultural-ai","农业AI与大模型","\u002Ftopic\u002Fdigital-agriculture\u002Fagricultural-ai","I",{"code":63,"slug":125,"name":126,"path":127,"parent_code":123},"remote-sensing","遥感与农情监测","\u002Ftopic\u002Fdigital-agriculture\u002Fremote-sensing",{"status":38,"locked":14,"version":39,"method":40,"evidence":129},{"candidates":130,"agricultural_evidence":44},[131,136,141,147,154,158,165,171,177],{"code":32,"score":132,"supported":44,"title":133,"abstract":134,"tags":135},15,[33],[26,33],[26],{"code":57,"score":20,"supported":44,"title":137,"abstract":139,"tags":140},[138],"machine learning",[],[28],{"code":63,"score":142,"supported":44,"title":143,"abstract":144,"tags":146},8,[],[30,145],"remote sensing",[116,30],{"code":148,"score":98,"supported":44,"title":149,"abstract":150,"tags":153},"A7",[],[151,152],"轮作","crop rotation",[],{"code":50,"score":98,"supported":44,"title":155,"abstract":156,"tags":157},[],[27,54],[],{"code":159,"score":160,"supported":44,"title":161,"abstract":162,"tags":164},"A2",3,[],[163],"wheat",[],{"code":166,"score":160,"supported":44,"title":167,"abstract":168,"tags":170},"A4",[],[169],"rapeseed",[],{"code":172,"score":160,"supported":44,"title":173,"abstract":174,"tags":176},"H8",[],[175],"可持续农业",[],{"code":178,"score":21,"supported":14,"title":179,"abstract":180,"tags":181},"I1",[],[],[115],[183,68],"长三角 水稻 种植模式 遥感","长三角水稻种植模式遥感-3494",5,"10.3390\u002Frs18193302",{"doi":186,"openalex_id":188,"authors":189,"venue":106,"cited_by_count":71,"oa_url":103,"card":210,"direction":93,"ingested_from":95},"W7214147197",[190,193,196,199,201,204,207],{"name":191,"orcid":192},"Xuan Li","https:\u002F\u002Forcid.org\u002F0000-0001-5509-2385",{"name":194,"orcid":195},"Lintao Chen","https:\u002F\u002Forcid.org\u002F0009-0000-6558-1289",{"name":197,"orcid":198},"Lin Chen","https:\u002F\u002Forcid.org\u002F0000-0002-9270-1626",{"name":200,"orcid":9},"Chao Su",{"name":202,"orcid":203},"Hoi Leong Lee","https:\u002F\u002Forcid.org\u002F0000-0002-4984-2183",{"name":205,"orcid":206},"Ruci Wang","https:\u002F\u002Forcid.org\u002F0000-0001-7049-7006",{"name":208,"orcid":209},"Xuguang Tang","https:\u002F\u002Forcid.org\u002F0009-0008-3494-8867",{"tldr":211,"method":212,"finding":213,"direction":93,"opportunity":214},"基于GEE融合Sentinel-1\u002F2时序与地形特征，用机器学习高精度制图长三角水稻种植模式。","GEE平台、Sentinel-1\u002F2时序特征、DEM、548个实地样本、RF\u002FG","GBTREE精度最高（总体93.8%、Kappa 0.87），双季稻识别最好；NDVI物候特征贡献最","可探索样本稀缺区迁移学习与多作物轮作模式泛化制图，并耦合产量与碳核算。","2026-09-25T23:30:30.511522Z",{"id":217,"title":218,"url":219,"summary":220,"summary_zh":221,"content":9,"source_name":222,"source_url":219,"published_at":11,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":223,"score_detail":224,"sources":226,"tags":228,"primary_topic":231,"secondary_topics":232,"classification":234,"search_phrases":263,"slug":266,"view_count":71,"doi":267,"paper":268,"created_at":281},5394,"Rice Yield Prediction Using Multi-Modal Regression Learning with Optimized Ensemble Models","https:\u002F\u002Fdoi.org\u002F10.3390\u002Feng7100572","Accurate rice yield estimation is important for agricultural planning, resource allocation, and food security assessment, but yield depends on interacting climatic, vegetation, remote sensing, seasonal, and crop growth factors.

Most deep learning methods for crop classification rely on multi‐temporal optical remote sensing data. However, it is difficult to obtain sufficient ground‐truth samples for time‐series deep learning models through conducting large‐scale field surveys, and persistent cloud and rainfall often limit optical observations during the rice‐growing seasons in subtropical regions. Rice classification based solely on time‐series optical images may therefore be less accurate and reliable. Here, we developed two dual‐branch deep learning networks for effective rice identification: one combining a long short‐term memory network running in parallel with a multi‐layer perceptron (LSTM + MLP), and the other replacing the LSTM with a one‐dimensional convolutional neural network (Conv1d + MLP). These models process temporal sequences in parallel with auxiliary data through the MLP, allowing them to automatically extract phenology information while incorporating auxiliary variables such as texture features, digital elevation model (DEM) data, and the standard deviation of the vegetation index time series. We evaluated these models in a representative county in the subtropical region of China, and compared the accuracies with standalone LSTM, Conv1d, MLP, and random forest (RF) models. The results revealed that LSTM + MLP had the highest accuracy, with an F1‐score of 95.5%, which can automatically extract rice growth patterns and successfully identify the key phenological information of flood signals during the rice transplanting period. By incorporating auxiliary variables, the model achieved an average accuracy improvement of 8.1% relative to the models using only temporal features. The proposed method provides a useful approach for rice mapping in subtropical regions.","准确绘制水稻这一全球最重要的粮食作物之一，对于监测其生长、估算产量以及保障全球粮食安全至关重要。大多数作物分类的深度学习方法依赖于多时相光学遥感数据。然而，通过开展大规模实地调查来获取足够的地面真值样本以用于时间序列深度学习模型十分困难，而且亚热带地区水稻生长季期间持续的云层和降雨往往限制了光学观测。因此，仅基于时间序列光学图像的水稻分类可能精度较低且可靠性不足。本研究开发了两种双分支深度学习网络以实现有效的水稻识别：一种将长短期记忆网络与多层感知机并行运行（LSTM + MLP），另一种则用一维卷积神经网络替代LSTM（Conv1d + MLP）。这些模型通过MLP将时间序列与辅助数据并行处理，使其能够自动提取物候信息，同时纳入纹理特征、数字高程模型（DEM）数据以及植被指数时间序列标准差等辅助变量。我们在中国亚热带地区一个代表性县对这些模型进行了评估，并将精度与单独的LSTM、Conv1d、MLP和随机森林（RF）模型进行了比较。结果表明，LSTM + MLP精度最高，F1分数达到95.5%，能够自动提取水稻生长模式，并成功识别水稻移栽期洪水信号的关键物候信息。通过纳入辅助变量，该模型相对于仅使用时间特征的模型平均精度提高了8.1%。所提出的方法为亚热带地区水稻制图提供了一种有效途径。","Journal of Sustainable Agriculture and Environment","2026-10-06T00:00:00Z",75,{"impact":132,"substance":369,"depth":370,"authority":371,"freshness":20,"relevant":21,"comment":372},21,17,13,"提出双分支深度学习网络融合时序与辅助数据，水稻识别F1达95.5%，方法新颖且结论可靠，对亚热带多云雨区作物遥感制图有实用价值。",[374],{"name":365,"url":362},[115,229,26,30,116],{"code":32,"slug":33,"name":26,"path":34,"parent_code":35},[378],{"code":63,"slug":125,"name":126,"path":127,"parent_code":123},{"status":38,"locked":14,"version":39,"method":40,"evidence":380},{"candidates":381,"agricultural_evidence":44},[382,386,390,395,399],{"code":32,"score":132,"supported":44,"title":383,"abstract":384,"tags":385},[33],[26,33],[26],{"code":63,"score":142,"supported":44,"title":387,"abstract":388,"tags":389},[],[30,145],[116,30],{"code":57,"score":51,"supported":44,"title":391,"abstract":392,"tags":394},[],[393,310],"深度学习",[229],{"code":50,"score":98,"supported":44,"title":396,"abstract":397,"tags":398},[],[27,54],[],{"code":178,"score":21,"supported":14,"title":400,"abstract":401,"tags":402},[],[],[115],[404,405],"水稻 遥感 分类 深度学习","亚热带 水稻 制图","水稻遥感分类深度学习-4356","10.1002\u002Fsae2.70218",{"doi":407,"openalex_id":409,"authors":410,"venue":365,"cited_by_count":71,"oa_url":430,"card":431,"direction":93,"ingested_from":95},"W7220691059",[411,413,416,419,421,424,427],{"name":412,"orcid":9},"Rongfei Ma",{"name":414,"orcid":415},"Wenjiao Shi","https:\u002F\u002Forcid.org\u002F0000-0001-6199-9733",{"name":417,"orcid":418},"Minglei Wang","https:\u002F\u002Forcid.org\u002F0000-0002-4174-9224",{"name":420,"orcid":9},"Xiwei Chen",{"name":422,"orcid":423},"Chenchen Zhang","https:\u002F\u002Forcid.org\u002F0000-0003-0458-6232",{"name":425,"orcid":426},"Baihong Pan","https:\u002F\u002Forcid.org\u002F0009-0004-1100-6798",{"name":428,"orcid":429},"Xiangming Xiao","https:\u002F\u002Forcid.org\u002F0000-0003-0956-7428","https:\u002F\u002Fonlinelibrary.wiley.com\u002Fdoi\u002Fpdfdirect\u002F10.1002\u002Fsae2.70218",{"tldr":432,"method":433,"finding":434,"direction":93,"opportunity":435},"提出双分支深度学习网络融合时序与辅助数据，提升亚热带水稻分类精度。","LSTM\u002FConv1d与MLP并行双分支网络，融合时序植被指数、纹理、DEM等辅","LSTM+MLP模型F1达95.5%，辅助变量使精度平均提升8.1%，能识别插秧期淹水信号。","可探索多源遥感与气象数据融合，解决多云雨地区时序缺失下的作物精细制图问题。","2026-10-07T23:30:25.945309Z",{"id":438,"title":439,"url":440,"summary":441,"summary_zh":442,"content":9,"source_name":443,"source_url":440,"published_at":444,"category":12,"cover_url":9,"hotness":445,"is_selected":14,"score":446,"score_detail":447,"sources":449,"tags":453,"primary_topic":454,"secondary_topics":455,"classification":458,"search_phrases":502,"slug":505,"view_count":71,"doi":506,"paper":507,"created_at":517},4310,"Comprehensive remote sensing and machine learning framework for multi-regional rice yield forecasting under hydroclimatic variability in Sahelian Niger","https:\u002F\u002Fdoi.org\u002F10.5281\u002Fzenodo.23149579","It is crucial to forecast rice yields effectively in order to improve agricultural planning and resilience to climate change in the Sahel, where production is greatly affected by hydroclimatic variability.

However, reductions in paddy field extent do not necessarily indicate decreased food availability, as agricultural systems may respond through intensification and productivity improvement. This study evaluated rice food availability resilience under paddy field land-use change in Sukabumi Regency, West Java, Indonesia, during 2000–2020 by integrating Landsat-based spatial analysis with agricultural production indicators. Paddy field dynamics were analyzed using multi-temporal Landsat imagery through Object-Based Image Analysis (OBIA) and Random Forest classification. Agricultural responses were assessed using harvested area, cropping intensity, productivity, rice production, and the Production Efficiency Index (PEI).The results showed that paddy field area declined from 71,641.44 ha in 2000 to 65,982.15 ha in 2020, representing a 7.9% reduction, with the largest decline occurring in rainfed paddy fields. Despite this reduction, rice production increased from 622,189 tons to 931,328 tons, supported by increases in harvested area, cropping intensity, and productivity, particularly within irrigated paddy field systems. The PEI increased from 8.68 to 14.12 ton ha⁻¹, indicating improved production efficiency relative to available land resources. These findings indicated that rice food availability resilience in Sukabumi Regency was supported by agricultural adaptation strategies, particularly through intensification and productivity enhancement rather than land expansion.Nevertheless, productivity improvements may not indefinitely compensate for continued paddy field conversion due to ecological and biophysical limitations. Integrating remote sensing-based land-use change analysis with agricultural performance indicators provides a useful framework for evaluating food availability resilience and supporting sustainable paddy field management.","水稻粮食供给日益受到社会经济发展和土地利用转型所驱动的稻田转换的挑战。然而，稻田面积的减少并不必然意味着粮食供给下降，因为农业系统可能通过集约化和生产力提升作出响应。本研究通过将基于Landsat的空间分析与农业生产指标相结合，评估了印度尼西亚西爪哇省苏加武眉县2000—2020年稻田土地利用变化下的水稻粮食供给韧性。稻田动态采用多时相Landsat影像，通过面向对象影像分析（OBIA）和随机森林分类进行分析。农业响应则通过收获面积、种植强度、生产力、水稻产量和生产效率指数（PEI）进行评估。结果表明，稻田面积从2000年的71,641.44公顷下降至2020年的65,982.15公顷，减少了7.9%，其中雨养稻田的降幅最大。尽管稻田面积减少，水稻产量却从622,189吨增加至931,328吨，这得益于收获面积、种植强度和生产力的提高，尤其是在灌溉稻田系统中。生产效率指数从8.68吨\u002F公顷上升至14.12吨\u002F公顷，表明相对于可用土地资源的生产效率有所提高。这些发现表明，苏加武眉县的水稻粮食供给韧性得益于农业适应策略，特别是通过集约化和生产力提升而非土地扩张来实现。然而，由于生态和生物物理限制，生产力的提高可能无法无限期地弥补稻田的持续转换。将基于遥感的土地利用变化分析与农业绩效指标相结合，为评估粮食供给韧性和支持可持续稻田管理提供了一个有用的框架。","Eduvest - Journal Of Universal Studies","2026-09-29T00:00:00Z",60,{"impact":142,"substance":17,"depth":109,"authority":20,"freshness":20,"relevant":21,"comment":528},"印尼区域案例，方法（Landsat+OBIA+随机森林）与结论有参考价值，但影响范围限于地方，适合作为遥感与耕地变化主题的补充素材。",[530],{"name":524,"url":521},[26,27,532,533,534],"耕地保护","遥感监测","土地利用",{"code":32,"slug":33,"name":26,"path":34,"parent_code":35},[],{"status":38,"locked":14,"version":39,"method":40,"evidence":538},{"candidates":539,"agricultural_evidence":44},[540,546,550,557,562,566,571],{"code":32,"score":541,"supported":44,"title":542,"abstract":543,"tags":545},26,[33,47],[26,544,33,47],"稻田",[26],{"code":63,"score":51,"supported":44,"title":547,"abstract":548,"tags":549},[],[30,145],[533],{"code":551,"score":98,"supported":44,"title":552,"abstract":553,"tags":556},"I4",[],[554,555],"空间分析","spatial analysis",[],{"code":481,"score":160,"supported":44,"title":558,"abstract":559,"tags":561},[],[560],"灌溉",[],{"code":50,"score":21,"supported":14,"title":563,"abstract":564,"tags":565},[],[],[27],{"code":567,"score":21,"supported":14,"title":568,"abstract":569,"tags":570},"H1",[],[],[532],{"code":572,"score":21,"supported":14,"title":573,"abstract":574,"tags":575},"H6",[],[],[534],[577,578],"Sukabumi 稻田 遥感","水稻 耕地转换 粮食供给","Sukabumi稻田遥感-3844","10.59188\u002Feduvest.v6i9.53513",{"doi":580,"openalex_id":582,"authors":583,"venue":524,"cited_by_count":71,"oa_url":521,"card":597,"direction":93,"ingested_from":95},"W7214788951",[584,586,589,591,594],{"name":585,"orcid":9},"Tatang Kurniawan",{"name":587,"orcid":588},"Widiatmaka Widiatmaka","https:\u002F\u002Forcid.org\u002F0000-0001-8613-9561",{"name":590,"orcid":9},"M.
