Based on the multispectral remote sensing data of Sentinel-2 and measured total phosphorus data of water bodies, the study used specific feature combinations such as NDTI, B5, B11-B12 difference, and sensitive combination bands of measured data as model inputs to construct a PSO-Adam-BP neural network machine learning model for total phosphorus concentration inversion. Compared with the traditional BP and PSO-BP baseline models, the proposed framework significantly improved the accuracy of the model, with an R2 value reaching 0.9351. Moreover, it successfully reduced the average relative error by up to 53.5%, from 4.80% to 2.24%, and decreased the maximum relative error by up to 31.7%, from 11.21% to 7.66%, demonstrating the model’s highly robust and precise inversion performance. This study provides a new method for water quality detection in Baiyangdian Lake and is of great significance to the protection and development of the water environment in Xiong’an New Area.","本研究以雄安新区白洋淀为研究对象，利用Sentinel-2多光谱影像和实地测量数据反演总磷（TP）浓度，旨在为水质评价和富营养化管理提供支持。基于Sentinel-2多光谱遥感数据和白洋淀水体总磷实测数据，研究采用NDTI、B5、B11-B12差值等特征组合及实测数据的敏感组合波段作为模型输入，构建了PSO-Adam-BP神经网络机器学习模型用于总磷浓度反演。与传统BP和PSO-BP基准模型相比，所提出的框架显著提高了模型精度，R²值达到0.9351。此外，该模型成功将平均相对误差最多降低53.5%，从4.80%降至2.24%，并将最大相对误差最多降低31.7%，从11.21%降至7.66%，展现出高度稳健且精确的反演性能。本研究为白洋淀水质检测提供了新方法，对雄安新区水环境保护与开发具有重要意义。",null,"Polish Journal of Environmental Studies","2026-09-18T00:00:00Z","论文",10,false,72,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},15,21,17,13,6,1,"基于Sentinel-2与PSO-Adam-BP模型实现白洋淀总磷浓度高精度反演，方法新颖、数据可靠，对雄安水环境智慧监测有实用价值。",[25],{"name":10,"url":6},[27,28,29,30,31],"农业人工智能","机器学习","遥感","水质监测","白洋淀",[],{"status":34,"locked":14,"version":35,"method":36,"evidence":37},"needs_review","2026-10-22.2","rules",{"candidates":38,"agricultural_evidence":14,"reason":54},[39,47],{"code":40,"score":13,"supported":41,"title":42,"abstract":43,"tags":46},"I3",true,[],[29,44,45],"remote sensing","multispectral",[29],{"code":48,"score":49,"supported":41,"title":50,"abstract":51,"tags":53},"I2",8,[],[28,52],"machine learning",[27,28],"农业相关性需要复核",[56,57],"白洋淀 总磷 遥感反演","Sentinel-2 水质 反演","白洋淀总磷遥感反演-3076",2,"10.15244\u002Fpjoes\u002F220960",{"doi":60,"openalex_id":62,"authors":63,"venue":10,"cited_by_count":79,"oa_url":80,"card":81,"direction":85,"ingested_from":87},"W7213537374",[64,66,68,71,74,76],{"name":65,"orcid":9},"Guanxing Wang",{"name":67,"orcid":9},"Cui Jia",{"name":69,"orcid":70},"Linghan Gao","https:\u002F\u002Forcid.org\u002F0000-0002-8537-8787",{"name":72,"orcid":73},"Shan An","https:\u002F\u002Forcid.org\u002F0000-0001-7796-6952",{"name":75,"orcid":9},"Jia Xi",{"name":77,"orcid":78},"Yaxue Liu","https:\u002F\u002Forcid.org\u002F0009-0006-9025-8030",0,"https:\u002F\u002Fwww.pjoes.com\u002Fpdf-220960-145347?filename=Research-on-the-Inversion.pdf",{"tldr":82,"method":83,"finding":84,"direction":85,"opportunity":86},"用PSO-Adam-BP神经网络结合Sentinel-2影像反演白洋淀总磷浓度。","Sentinel-2多光谱与实测数据，NDTI等特征组合，PSO-Adam-BP","R²达0.9351，平均相对误差由4.80%降至2.24%，精度显著优于BP与PSO-BP。","农业遥感与作物表型","可迁移至其他内陆水体与多参数水质反演，探索时序泛化与跨区域迁移能力。","openalex","2026-09-21T23:30:25.856035Z",{"total":21,"page":22,"page_size":21,"items":90},[91,148,210,279,341,405],{"id":92,"title":93,"url":94,"summary":95,"summary_zh":96,"content":9,"source_name":97,"source_url":94,"published_at":98,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":99,"score_detail":100,"sources":104,"tags":106,"primary_topic":9,"secondary_topics":108,"classification":109,"search_phrases":122,"slug":125,"view_count":126,"doi":127,"paper":128,"created_at":147},2433,"Hierarchical spectral ensemble with physics-informed augmentation for global water quality retrieval from hyperspectral remote sensing","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffrsen.2026.1860176","Retrieving water quality variables from remotely sensed reflectance spectra (Rrs) with global-scale, cross-waterbody applicability remains a grand challenge in environmental remote sensing. Here we introduce Hierarchical Spectral Ensemble (HSE), a machine learning pipeline for concurrent retrieval of four ecologically relevant water quality parameters (chlorophyll-a (Chl-a), total suspended solids (TSS), coloured dissolved organic matter absorption coefficient at 440 nm (aCDOM(440)), and Secchi depth (Zsd)), applied to the GLORIA 2022 global dataset of 7,572 co-located hyperspectral in situ ground truth measurements spanning six continents. HSE leverages a combination of five diverse base learners trained with 10-fold out-of-fold stacking, and integrated with a diversity-constrained non-negative least squares (NNLS) meta-learner, supported by a 291-dimensional feature suite spanning spectral, spatial, and temporal representations. We propose Interpolation-based Spectral Data Augmentation (ISDA), an ecologically inspired, class-balance oversampling methodology applied to the training set after the initial stratified split to prevent information leakage. Evaluated on the held-out global test set, HSE attains R2 = 0.822, 0.704, 0.841, and 0.962 for Chl-a, TSS, aCDOM(440), and Zsd respectively (mean R2 = 0.832; all in original physical units following back-transformation). Stratified analysis on a per-quartile basis reveals negative values of R2 in low-concentration regimes for Chl-a, TSS, and aCDOM(440), illustrating how global metrics can mask failures in retrieval across a majority of the distribution, specifically in the oligotrophic regime. This constitutes the primary known limitation of the method: reliable prediction in low-concentration, low-optical-signal regimes remains elusive and is demonstrated only in high-concentration, eutrophic samples where a measurable optical signal exists.","从遥感反射光谱（Rrs）中反演水质变量并实现全球尺度、跨水体的适用性，仍是环境遥感领域的一项重大挑战。本文提出分层光谱集成（Hierarchical Spectral Ensemble, HSE），一种机器学习流程，用于同时反演四个与生态相关的水质参数（叶绿素a（Chl-a）、总悬浮固体（TSS）、440 nm处有色溶解有机物吸收系数（aCDOM(440)）和透明度（Zsd）），并应用于GLORIA 2022全球数据集，该数据集包含横跨六大洲的7,572组同步高光谱原位地面实测数据。HSE结合了五种不同的基学习器，采用10折折外堆叠进行训练，并与多样性约束的非负最小二乘（NNLS）元学习器集成，辅以涵盖光谱、空间和时间表示的291维特征集。我们提出基于插值的光谱数据增强（Interpolation-based Spectral Data Augmentation, ISDA），这是一种受生态学启发的类平衡过采样方法，在初始分层划分后应用于训练集以防止信息泄漏。在留出的全球测试集上评估，HSE在Chl-a、TSS、aCDOM(440)和Zsd上分别达到R2 = 0.822、0.704、0.841和0.962（平均R2 = 0.832；均在反变换后以原始物理单位表示）。基于四分位数的分层分析揭示了Chl-a、TSS和aCDOM(440)在低浓度条件下R2为负值，说明全球指标可能掩盖分布中大多数区域的检索失败，特别是在贫营养条件下。这构成了该方法已知的主要局限性：在低浓度、低光学信号条件下实现可靠预测仍然难以实现，仅在存在可测量光学信号的高浓度、富营养化样本中得到验证。","Frontiers in Remote Sensing","2026-09-11T00:00:00Z",79,{"impact":101,"substance":102,"depth":101,"authority":20,"freshness":49,"relevant":22,"comment":103},18,22,"基于GLORIA全球高光谱数据集提出分层光谱集成方法，可同步反演叶绿素a、悬浮物等四项水质参数，方法新颖、数据规模大，但低浓度水体反演失效的局限也交代清楚，对农业水环境遥感监测有参考价值。",[105],{"name":97,"url":94},[27,28,29,30,107],"水环境",[],{"status":34,"locked":14,"version":35,"method":36,"evidence":110},{"candidates":111,"agricultural_evidence":14,"reason":54},[112,118],{"code":40,"score":113,"supported":41,"title":114,"abstract":116,"tags":117},26,[44,115],"hyperspectral",[29,44,115],[29],{"code":48,"score":49,"supported":41,"title":119,"abstract":120,"tags":121},[],[28,52],[27,28],[123,124],"农业人工智能 机器学习 水质监测 水环境","农业人工智能 机器学习","农业人工智能机器学习水质监测水环境-2433",3,"10.3389\u002Ffrsen.2026.1860176",{"doi":127,"openalex_id":129,"authors":130,"venue":97,"cited_by_count":79,"oa_url":141,"card":142,"direction":85,"ingested_from":87},"W7212323204",[131,133,135,137,139],{"name":132,"orcid":9},"Amirthalakshmi TM",{"name":134,"orcid":9},"Hemanth S",{"name":136,"orcid":9},"Ganesan PV",{"name":138,"orcid":9},"Rahul SG",{"name":140,"orcid":9},"Gayathri M","https:\u002F\u002Fwww.frontiersin.org\u002Fjournals\u002Fremote-sensing\u002Farticles\u002F10.3389\u002Ffrsen.2026.1860176\u002Fpdf",{"tldr":143,"method":144,"finding":145,"direction":85,"opportunity":146},"提出分层光谱集成模型HSE，从高光谱遥感反射率中全球尺度反演四种水质参数。","用GLORIA 2022全球7572条高光谱数据，结合10折堆叠集成、NNLS元","整体R²达0.832，但低浓度贫营养水体中Chl-a、TSS、aCDOM(440)的R²为负，反演失","低浓度、弱光学信号水体的反演仍是空白，可探索物理约束与少样本学习提升贫营养水体精度。","2026-09-14T23:30:27.361699Z",{"id":149,"title":150,"url":151,"summary":152,"summary_zh":153,"content":9,"source_name":154,"source_url":151,"published_at":155,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":156,"score_detail":157,"sources":162,"tags":164,"primary_topic":9,"secondary_topics":167,"classification":168,"search_phrases":186,"slug":189,"view_count":79,"doi":190,"paper":191,"created_at":209},4680,"Groundwater Potential Mapping in Northwestern Nigeria: A Comparison of the Analytic Hierarchy Process and Galileo-Enhanced CAT-XGB","https:\u002F\u002Fdoi.org\u002F10.31223\u002Fx5mv5h","Global water scarcity intensifies the need for high-resolution groundwater assessment tools, yet traditional approaches struggle to reconcile qualitative expert weights with the extensive spatial coverage offered by remote sensing data.

Standard thematic layers were integrated with embeddings from a pretrained remote sensing foundation model to train ensemble classifiers, with groundwater potential validated against Vertical Electrical Sounding (VES) data. The foundation-model-enhanced CAT-XGB ensemble achieved notable predictive performance, consistently outperforming standalone tree-based classifiers and traditional AHP. Spatial difference mapping revealed that the enhanced ensemble captured critical, localized hydrogeological anomalies smoothed over by expert-driven weighting.

This study develops a fully automated Python workflow that integrates Geographic Information Systems (GIS), remote sensing, and machine learning to classify pervious and impervious surfaces and monitor urbanization dynamics in the central area of Ho Chi Minh City (about 95,100 hectares). A multi-temporal dataset was compiled from Landsat 5, Landsat 8, and Landsat 9 imagery (30 m) and Sentinel-2 imagery (10 m) for 2009, 2017, and 2024. The reference dataset comprised 1,125 survey points (549 impervious and 582 pervious) and 127 field points for independent validation. The workflow performs image preprocessing, Normalized Difference Built-up Index (NDBI) computation, a 70\u002F30 train-test split, and supervised classification using Random Forest (RF), Support Vector Machine (SVM), and K-Nearest Neighbors (KNN). The main novelty lies in (i) an end-to-end, reproducible Python pipeline that requires no manual GIS post-processing, (ii) the joint use of Landsat and Sentinel-2 data over 15 years for a rapidly urbanizing Southeast Asian city, and (iii) a controlled benchmark of three algorithm families using identical inputs. RF achieved the highest performance (overall accuracy 96.97%, Kappa 0.94), closely followed by SVM (96.77%, 0.94); KNN performed lower (90.91%, 0.82).

However, the heterogeneous and fragmented character of agricultural landscapes in southeastern Nigeria presents substantial challenges for satellite-image classification. This study comparatively evaluated Random Forest (RF), Support Vector Machine (SVM), Artificial Neural Network (ANN), and Convolutional Neural Network (CNN) for agricultural land mapping in Anambra State, Nigeria. Remotely sensed imagery was classified into waterbody, dense forest, agricultural land, built-up area, and bare ground using the four algorithms. Model performance was evaluated using 210 validation samples and multiple confusion-matrix metrics, including sensitivity, precision, specificity, negative predictive value, overall accuracy, balanced accuracy, and Matthew’s correlation coefficient. Agricultural land estimates varied from 1,000.26 km² (21.78%) for SVM to 1,099.12 km² (23.93%) for ANN. SVM achieved the strongest overall performance, recording 88.5% sensitivity, 85.2% precision, 75.0% specificity, 83.3% overall accuracy, 81.7% balanced accuracy, and a Matthews correlation coefficient of 0.643. CNN produced the lowest overall accuracy of 74.3%. The findings demonstrate that increased model complexity does not necessarily translate into superior classification performance and establish SVM as an effective approach for regional agricultural land delineation under heterogeneous tropical landscape conditions.

These interacting pressures create complex and nonlinear relationships among physicochemical water-quality parameters, watershed characteristics, and pollutant dynamics, making conventional monitoring approaches insufficient for comprehensive and timely assessment. This study develops a data-driven machine learning framework for surface water quality assessment, prediction, pollution-event detection, and management in Malaysian river systems. The proposed framework integrates physicochemical, hydrological, spatial, land-use, and anthropogenic variables to characterize the temporal and spatial variability of water-quality conditions. The investigated parameters include dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, pH, temperature, electrical conductivity, turbidity, total suspended solids, ammoniacal nitrogen, nitrate, phosphate, total nitrogen, and total phosphorus, together with rainfall, streamflow, water level, antecedent rainfall, urbanization, agricultural land use, industrial land use, population density, wastewater pressure, and road density. Seven machine learning approaches are incorporated, including Decision Trees (DT), Random Forest (RF), Support Vector Machines (SVM), Support Vector Regression (SVR), Artificial Neural Networks (ANN), Long Short-Term Memory (LSTM) networks, and hybrid ensemble models. The Malaysian National Water Quality Standards and Water Quality Index (WQI) are incorporated to establish the regulatory and quantitative basis for water-quality classification and prediction. The framework further integrates explainable artificial intelligence techniques, including SHAP and LIME, to quantify predictor contributions and identify the dominant environmental and anthropogenic factors governing model outputs. The proposed methodology enables simultaneous water-quality classification, continuous prediction, anomaly and pollution-event detection, source-pressure identification, and management-oriented decision support. Particular emphasis is placed on temporal variability, nonlinear interactions, hydrological influence, land-use effects, and the integration of multiple environmental data sources. The study provides a comprehensive Malaysia-oriented machine learning framework that can enhance conventional surface-water monitoring by combining predictive modeling, explainability, and integrated watershed information. The findings establish a methodological basis for developing real-time and transferable water-quality prediction systems capable of supporting pollution mitigation, watershed management, and sustainable water-resource planning across Malaysian river basins.","马来西亚地表水水质日益受到快速城市化、工业扩张、农业活动、废水排放、气候变率以及水文情势变化的影响。这些相互作用压力在物理化学水质参数、流域特征与污染物动态之间形成了复杂的非线性关系，使传统监测方法难以实现全面且及时的评估。本研究开发了一个数据驱动的机器学习框架，用于马来西亚河流系统的地表水水质评估、预测、污染事件检测与管理。所提出的框架整合了物理化学、水文、空间、土地利用和人为变量，以刻画水质条件的时间与空间变异性。所研究的参数包括溶解氧、生化需氧量、化学需氧量、pH、温度、电导率、浊度、总悬浮固体、氨氮、硝酸盐、磷酸盐、总氮和总磷，以及降雨量、河流流量、水位、前期降雨、城市化、农业用地、工业用地、人口密度、废水压力和道路密度。该框架纳入了七种机器学习方法，包括决策树（DT）、随机森林（RF）、支持向量机（SVM）、支持向量回归（SVR）、人工神经网络（ANN）、长短期记忆（LSTM）网络以及混合集成模型。研究纳入马来西亚国家水质标准和水质指数（WQI），以建立水质分类与预测的监管和定量基础。该框架进一步整合了可解释人工智能技术，包括SHAP和LIME，以量化预测因子的贡献并识别主导模型输出的主要环境与人为因素。所提出的方法能够同时实现水质分类、连续预测、异常与污染事件检测、源压力识别以及面向管理的决策支持。研究特别强调时间变异性、非线性相互作用、水文影响、土地利用效应以及多环境数据源的整合。该研究提供了一个面向马来西亚的综合机器学习框架，可增强传统","The International Journal of Engineering Sciences","2026-09-22T00:00:00Z",68,{"impact":158,"substance":159,"depth":19,"authority":13,"freshness":309,"relevant":22,"comment":415},"马来西亚河流水质机器学习框架，方法体系完整但属区域性研究，对国内农业信息化参考价值有限。",[417],{"name":411,"url":408},[27,28,419,30,420],"可解释AI","流域管理",{"code":48,"slug":227,"name":228,"path":229,"parent_code":230},[],{"status":239,"locked":14,"version":35,"method":36,"evidence":424},{"candidates":425,"agricultural_evidence":41},[426],{"code":48,"score":159,"supported":41,"title":427,"abstract":428,"tags":430},[52],[28,52,245,429],"decision support",[27,419,28],[432,433],"马来西亚 地表水 机器学习","水质指数 机器学习 预测","马来西亚地表水机器学习-3280","10.64440\u002Fijes\u002Fengineeringx0021",{"doi":435,"openalex_id":437,"authors":438,"venue":411,"cited_by_count":79,"oa_url":408,"card":457,"direction":275,"ingested_from":87},"W7214031821",[439,441,443,445,447,449,451,453,455],{"name":440,"orcid":9},"Iskandar M.
