This paper examines urban expansion as a major cause of forest loss in Asaba metropolis, Delta State, Nigeria, drawing on geospatial analysis of four epochs of Landsat satellite imagery spanning 1991 to 2021. Supervised Maximum Likelihood Classification (MLC) was applied to extract land use and land cover (LULC) data across six categories, while Normalized Difference Vegetation Index (NDVI), Normalized Difference Building Index (NDBI), Land Surface Temperature (LST), and Urban Heat Island (UHI) indices were computed to assess the spatial dimensions of urban-induced environmental change. Overall classification accuracy exceeded 97% for all epochs, with Kappa coefficients ranging from 0.92 to 0.98. Findings reveal that built-up area expanded from 0.91% of the total metropolitan land mass in 1991 to 26.56% in 2021, while vegetation cover declined from 18.19% to 8.83% over the same period. Farm land also contracted from 68.34% to 53.17%, confirming the compound nature of green land loss. NDBI values rose progressively from -0.18 to 0.17 in 1991 to 4.7 to 9.4 in 2021, while NDVI values contracted sharply to a range of -0.09 to 0.39 by 2021, indicating widespread vegetation degradation. Land surface temperature and urban heat island intensity also increased across the study period, reflecting the thermal consequences of reduced green cover and expanding impervious surfaces. Projections indicate that built-up area could reach approximately 51% of the metropolitan land mass by 2051 under current growth trajectories. The study concludes that urban expansion is a primary and ongoing cause of forest loss in Asaba metropolis and calls for integrated land use planning, green infrastructure policies, and strict enforcement of forest conservation regulations as essential steps toward sustainable urban development in peri-urban areas.","城市扩张日益被视为撒哈拉以南非洲森林丧失的主要驱动因素，对生物多样性、气候调节、碳汇和人类福祉产生深远影响。本文基于对1991年至2021年四个时期Landsat卫星影像的地理空间分析，考察了城市扩张作为尼日利亚三角洲州阿萨巴大都市森林丧失主因的作用。研究采用监督最大似然分类法（MLC）提取六类土地利用与土地覆盖（LULC）数据，同时计算归一化植被指数（NDVI）、归一化建筑指数（NDBI）、地表温度（LST）和城市热岛（UHI）指数，以评估城市引发的环境变化的空间维度。所有时期的总体分类精度均超过97%，Kappa系数介于0.92至0.98之间。研究结果表明，建成区面积从1991年占大都市土地总面积的0.91%扩展至2021年的26.56%，而植被覆盖同期从18.19%下降至8.83%。农田也从68.34%缩减至53.17%，证实了绿地丧失的复合性质。NDBI值从1991年的-0.18至0.17逐步上升至2021年的4.7至9.4，而NDVI值到2021年急剧收缩至-0.09至0.39之间，表明植被广泛退化。地表温度和城市热岛强度在研究期间也持续上升，反映了绿地覆盖减少和不透水面扩张的热效应。预测表明，在当前增长轨迹下，到2051年建成区面积可能达到大都市土地总面积的约51%。研究结论认为，城市扩张是阿萨巴大都市森林丧失的主要且持续的原因，并呼吁将综合土地利用规划、绿色基础设施政策和森林保护法规的严格执行作为城郊地区可持续城市发展的必要举措。",null,"OpenAlex","2026-09-30T00:00:00Z","论文",10,false,0,{"impact":15,"substance":15,"depth":15,"authority":15,"freshness":15,"relevant":15,"comment":17},"研究尼日利亚城市扩张致森林损失，属城市地理与遥感领域，与三农、农业信息化、数字乡村主题无关，不建议入选。",[19],{"name":10,"url":6},[21,22,23,24],"遥感监测","土地利用","城市扩张","森林损失",{"code":26,"slug":27,"name":28,"path":29,"parent_code":30},"H6","biodiversity","生态保护与生物多样性","\u002Ftopic\u002Fenvironment\u002Fbiodiversity","H",[],{"status":33,"locked":14,"version":34,"method":35,"evidence":36},"classified","2026-10-22.2","rules",{"candidates":37,"agricultural_evidence":40},[38,45,53,60],{"code":26,"score":39,"supported":40,"title":41,"abstract":42,"tags":44},7,true,[],[43,27],"生物多样性",[22],{"code":46,"score":47,"supported":40,"title":48,"abstract":49,"tags":52},"H4",6,[],[50,51],"碳汇","carbon sequestration",[],{"code":54,"score":55,"supported":40,"title":56,"abstract":57,"tags":59},"I4",3,[],[58],"空间分析",[],{"code":61,"score":62,"supported":14,"title":63,"abstract":64,"tags":65},"I3",1,[],[],[21],[67,68],"Asaba 城市扩张 森林损失","尼日利亚 Landsat 遥感","Asaba城市扩张森林损失-4104","10.54117\u002Ffyk4yw69",{"doi":70,"openalex_id":72,"authors":73,"venue":9,"cited_by_count":15,"oa_url":76,"card":77,"direction":81,"ingested_from":83},"W7214933722",[74],{"name":75,"orcid":9},"Ifeanyi Patricia Egwunyenga","https:\u002F\u002Fjournals.ipsintelligentsia.com\u002Fenvironmental-science\u002Findex.php\u002Fijes\u002Farticle\u002Fdownload\u002F44\u002F41",{"tldr":78,"method":79,"finding":80,"direction":81,"opportunity":82},"用1991-2021年Landsat影像分析尼日利亚阿萨巴城市扩张导致的森林与绿地损失。","Landsat影像、最大似然监督分类、NDVI\u002FNDBI\u002FLST\u002FUHI指数与趋","建设用地由0.91%升至26.56%，植被由18.19%降至8.83%，地表温度与热岛强度同步上升。","农业遥感与作物表型","可结合多源遥感与CA-Markov模型，量化城市扩张对周边农地与碳汇的耦合影响并模拟未来情景。","openalex","2026-10-03T23:30:38.105052Z",{"total":47,"page":62,"page_size":47,"items":86},[87,146,212,292,371,439],{"id":88,"title":89,"url":90,"summary":91,"summary_zh":92,"content":9,"source_name":93,"source_url":90,"published_at":94,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":95,"score_detail":96,"sources":102,"tags":104,"primary_topic":108,"secondary_topics":109,"classification":110,"search_phrases":121,"slug":124,"view_count":62,"doi":125,"paper":126,"created_at":145},4430,"Spatio temporal land use and land cover changes in a peri urban protected area of Kamrup Metropolitan District, Assam, India using geospatial techniques","https:\u002F\u002Fdoi.org\u002F10.1007\u002Fs44415-026-00134-4","Protection from human- induced pressures is vital to the survival of peri-urban protected areas, particularly in fast-growing urban areas. This research focuses on land use and land cover change in the Amchang Wildlife Sanctuary located in peri-urban region of Guwahati city in Kamrup Metropolitan district, Assam, India over 30 years period (1995–2025). Multi-temporal Landsat imagery was classified using Random Forest analysis with the help of NDVI, NDWI, NDBI, and delineated seven LULC categories dense forest, moderately dense forest, open forest, agriculture, built-up, barren land, and water bodies, with an overall Accuracy 81.57% and Kappa coefficient of 0.78. Landscape metrics such as Shannon’s Diversity Index, Patch Count, Edge Length were calculated and integrated with the Thiel-Sen’s slope calculation and the Mann–Kendall to determine fragmentation and longer-term trend analysis. The results showed a Net change in Dense Forest decreased by 51.7% (− 4.28 sq km), and Water Bodies by 73.5% (− 0.19 sq km), area increased in Built Up by 37.6% (+ 2.95 sq km), Agriculture by + 6.8% (+ 0.50 sq km) and Barren land by 7.3% (+ 0.15 sq km), as well as a type of secondary succession within Moderately Dense Forest by 35.5% (+ 6.11 sq km). This study is distinctive by the integration of Random forest classification, landscape fragmentation metrics and non-parametric trend analysis to weigh long term ecosystem vulnerability within peri-urban protected areas. Additionally, by connecting ecological monitoring and Sustainable Development Goals (i.e., 11, 13, 15) it will provide an established methodology for conservation planning\u002Frestoration strategies and sustainable expansion of urban areas in biodiversity hotspots.","保护免受人为压力对于城郊保护区的存续至关重要，在快速扩张的城市区域尤为如此。本研究聚焦印度阿萨姆邦卡姆鲁普大都会区古瓦哈提市城郊地区阿姆昌野生动物保护区30年期间（1995—2025年）的土地利用与土地覆盖变化。研究利用多时相Landsat影像，借助NDVI、NDWI、NDBI进行随机森林（Random Forest）分类，划分出7类土地利用与土地覆盖类型：密林、中度密林、疏林、农业用地、建设用地、裸地和水体，总体精度为81.57%，Kappa系数为0.78。研究计算了香农多样性指数、斑块数量、边缘长度等景观指标，并将其与Thiel-Sen斜率估计和Mann-Kendall检验相结合，以确定破碎化程度并开展长期趋势分析。结果表明，密林净减少51.7%（−4.28平方公里），水体净减少73.5%（−0.19平方公里）；建设用地增加37.6%（+2.95平方公里），农业用地增加6.8%（+0.50平方公里），裸地增加7.3%（+0.15平方公里）；中度密林内部出现一种次生演替，增加35.5%（+6.11平方公里）。本研究的独特性在于整合随机森林分类、景观破碎化指标和非参数趋势分析，以评估城郊保护区的长期生态系统脆弱性。此外，通过将生态监测与可持续发展目标（即目标11、13、15）相联系，本研究将为生物多样性热点地区的保护规划\u002F恢复策略及城市可持续扩张提供一套成熟的方法论。","Discover Forests","2026-10-06T00:00:00Z",65,{"impact":97,"substance":98,"depth":99,"authority":100,"freshness":97,"relevant":62,"comment":101},8,20,17,12,"基于Landsat与随机森林的30年城郊保护区土地利用变化研究，方法整合与数据规模扎实，但属区域性案例，公共影响有限。",[103],{"name":93,"url":90},[105,21,22,106,107],"可持续发展","野生动物保护","生态脆弱性",{"code":26,"slug":27,"name":28,"path":29,"parent_code":30},[],{"status":33,"locked":14,"version":34,"method":35,"evidence":111},{"candidates":112,"agricultural_evidence":40},[113,117],{"code":26,"score":97,"supported":40,"title":114,"abstract":115,"tags":116},[],[43,27],[22,106],{"code":61,"score":62,"supported":14,"title":118,"abstract":119,"tags":120},[],[],[21],[122,123],"Amchang Wildlife Sanctuary 土地利用","Assam 保护区 遥感","AmchangWildlifeSanctuary土地利用-4430","10.1007\u002Fs44415-026-00134-4",{"doi":125,"openalex_id":127,"authors":128,"venue":93,"cited_by_count":15,"oa_url":139,"card":140,"direction":81,"ingested_from":83},"W7220738321",[129,131,134,137],{"name":130,"orcid":9},"Trishna Changkakoti",{"name":132,"orcid":133},"Parimita Saikia","https:\u002F\u002Forcid.org\u002F0000-0001-9464-3450",{"name":135,"orcid":136},"Palme Borthakur","https:\u002F\u002Forcid.org\u002F0000-0002-0679-2040",{"name":138,"orcid":9},"Monshree Roy","https:\u002F\u002Flink.springer.com\u002Fcontent\u002Fpdf\u002F10.1007\u002Fs44415-026-00134-4.pdf",{"tldr":141,"method":142,"finding":143,"direction":81,"opportunity":144},"用遥感与景观指标分析印度阿萨姆城郊保护区30年土地利用变化与破碎化。","Landsat多时相影像、随机森林分类、NDVI\u002FNDWI\u002FNDBI、景观指标与","密林减少51.7%、水体减少73.5%，建设用地增37.6%，保护区破碎化加剧。","可将该遥感-景观-趋势集成框架迁移到中国城郊保护区的耕地撂荒与生态脆弱性监测。","2026-10-08T23:30:26.862434Z",{"id":147,"title":148,"url":149,"summary":150,"summary_zh":151,"content":9,"source_name":152,"source_url":149,"published_at":153,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":154,"score_detail":155,"sources":159,"tags":161,"primary_topic":165,"secondary_topics":166,"classification":167,"search_phrases":195,"slug":198,"view_count":55,"doi":199,"paper":200,"created_at":211},3793,"Digital Mapping for Land Use Planning in Oko, a Rapidly Urbanizing Region of Southeastern Nigeria","https:\u002F\u002Fdoi.org\u002F10.56201\u002Fijgem.vol.11.no11.2025.pg102.112","This report presents a comprehensive analysis of the land-use\u002Fland-cover (LULC) dynamics in Oko, Anambra State, Nigeria, over 30 years from 1995 to 2025. Leveraging existing remote sensing studies that utilized multi-temporal Landsat satellite imagery, this analysis quantifies the significant transformations in the landscape. The findings reveal a landscape under intense pressure, characterized by rapid urbanization, agricultural expansion, and a dramatic increase in gully erosion, largely at the expense of forest and vegetation cover. The primary drivers identified include demographic shifts linked to the Federal Polytechnic Oko, agricultural practices on marginal lands, and gaps in land-use policy enforcement. These changes have profound environmental and socio-economic implications, including heightened flood risk, loss of biodiversity, and threats to infrastructure and livelihoods. The results demonstrate that arable land has been lost due to the fast expansion of built-up areas, which increased by 48% between 2000 and 2025. The study shows how effective and replicable digital mapping is for spatial planning in settings with limited resources. The report concludes with targeted recommendations for sustainable land-use planning, policy reform, and future monitoring to mitigate ongoing environmental degradation and foster climate resilience in the region.","本报告对尼日利亚阿南布拉州奥科地区1995年至2025年30年间的土地利用\u002F土地覆盖（LULC）动态进行了综合分析。本分析依托现有利用多时相Landsat卫星影像的遥感研究，量化了景观的重大转变。研究结果揭示了一个承受巨大压力的景观，其特征为快速城市化、农业扩张以及沟蚀的急剧增加，而这些变化主要以森林和植被覆盖的丧失为代价。所识别的主要驱动因素包括与奥科联邦理工学院相关的人口变化、边缘土地上的农业活动以及土地利用政策执行方面的缺口。这些变化产生了深远的环境和社会经济影响，包括洪水风险加剧、生物多样性丧失以及对基础设施和生计的威胁。结果表明，由于建成区的快速扩张，耕地已经丧失，建成区在2000年至2025年间增加了48%。该研究表明，在资源有限的环境中，有效且可复制的数字制图对于空间规划具有重要意义。报告最后提出了有针对性的建议，涉及可持续土地利用规划、政策改革和未来监测，以缓解持续的环境退化并促进该地区的气候韧性。","IIARD INTERNATIONAL JOURNAL OF GEOGRAPHY AND ENVIRONMENTAL MANAGEMENT","2026-09-28T00:00:00Z",62,{"impact":97,"substance":156,"depth":157,"authority":100,"freshness":97,"relevant":62,"comment":158},18,16,"基于30年Landsat影像量化尼日利亚Oko地区土地利用变化与沟蚀扩张，方法可复制，对资源有限地区的数字制图与空间规划有参考价值，但属区域案例，公共影响有限。",[160],{"name":152,"url":149},[162,21,22,163,164],"数字乡村","水土保持","空间规划",{"code":26,"slug":27,"name":28,"path":29,"parent_code":30},[],{"status":33,"locked":14,"version":34,"method":35,"evidence":168},{"candidates":169,"agricultural_evidence":40},[170,174,180,186,190],{"code":26,"score":97,"supported":40,"title":171,"abstract":172,"tags":173},[],[43,27],[22,163],{"code":61,"score":39,"supported":40,"title":175,"abstract":176,"tags":179},[],[177,178],"遥感","remote sensing",[21],{"code":181,"score":55,"supported":40,"title":182,"abstract":183,"tags":185},"H7",[],[184],"climate resilience",[],{"code":54,"score":62,"supported":14,"title":187,"abstract":188,"tags":189},[],[],[164],{"code":191,"score":62,"supported":14,"title":192,"abstract":193,"tags":194},"I6",[],[],[162],[196,197],"尼日利亚 Oko 土地利用","Landsat 遥感 沟蚀","尼日利亚Oko土地利用-3793","10.56201\u002Fijgem.vol.11.no11.2025.pg102.112",{"doi":199,"openalex_id":201,"authors":202,"venue":152,"cited_by_count":15,"oa_url":205,"card":206,"direction":81,"ingested_from":83},"W7214637577",[203],{"name":204,"orcid":9},"Ifeanyi Washington N.

However, rapid urbanization has accelerated the conversion of wetlands to built-up areas and agricultural land, threatening their ecological integrity. This study assessed the impact of urbanization on agriculture and wetland management in Makurdi Local Government Area, Benue State, over a twenty-year period (2004–2024). The specific objectives were to examine the spatial distribution and extent of wetlands, evaluate the relationship between urban growth and wetland dynamics, and determine the extent of wetland encroachment resulting from urban development. The study employed Geographic Information Systems (GIS) and Remote Sensing techniques using Landsat 7 ETM+, Landsat 8 OLI\u002FTIRS, and Landsat 9 OLI-2\u002FTIRS-2 satellite imagery acquired for 2004, 2014, and 2024. Image preprocessing, supervised classification, change detection, cross-tabulation matrix analysis, and accuracy assessment were performed in ArcGIS and ERDAS Imagine, while field observations and GPS data were used for ground-truthing and validation. Seven land-use\u002Fland-cover classes were identified: wetlands, farmland, shrubland, forest, water bodies, sandbars, and settlements. The findings revealed significant land-use and land-cover changes over the study period. Wetland coverage declined from 4,478.76 ha (5.37%) in 2004 to 2,664.36 ha (2.39%) in 2024, while settlements expanded from 1,182.60 ha (1.42%) to 5,119.22 ha (4.61%) during the same period. Farmland increased from 39.23% to 41.09%, indicating continued conversion of natural ecosystems to agricultural and urban uses. Cross-tabulation analysis further demonstrated substantial transitions of wetlands and farmlands into settlement areas, confirming that urban expansion has become a major driver of wetland degradation in Makurdi. Classification accuracy assessments yielded overall accuracies ranging from 72.15% to 75.93%, with Kappa coefficients between 0.60 and 0.68, indicating that the classified maps were sufficiently reliable for land-use change analysis. The study concludes that rapid urbanization has significantly contributed to wetland loss and fragmentation and has increasingly encroached on agricultural lands, posing serious threats to ecosystem sustainability, biodiversity conservation, flood regulation, and long-term food security. To address these challenges, the study recommends strengthening wetland protection policies, implementing continuous GIS-based monitoring, promoting sustainable urban development, and establishing institutional frameworks to conserve and effectively manage wetlands and agricultural lands in Makurdi","湿地是最具生产力的生态系统之一，提供重要的生态、水文和社会经济服务，包括洪水调节、地下水补给、水质净化、生物多样性保护和农业支持。然而，快速城市化加速了湿地向建成区和农业用地的转化，威胁其生态完整性。本研究评估了贝努埃州马库尔迪地方政府区二十年期间（2004—2024年）城市化对农业和湿地管理的影响。具体目标包括：考察湿地的空间分布与范围，评估城市增长与湿地动态之间的关系，并确定城市发展导致的湿地侵占程度。研究采用地理信息系统（GIS）和遥感技术，使用2004年、2014年和2024年的Landsat 7 ETM+、Landsat 8 OLI\u002FTIRS和Landsat 9 OLI-2\u002FTIRS-2卫星影像。在ArcGIS和ERDAS Imagine中进行了影像预处理、监督分类、变化检测、交叉列联表矩阵分析和精度评估，同时利用实地观测和GPS数据进行地面验证与确认。研究识别出七类土地利用\u002F土地覆盖类型：湿地、农田、灌丛、森林、水体、沙洲和居民点。研究结果显示，研究期间土地利用和土地覆盖发生了显著变化。湿地覆盖面积从2004年的4,478.76公顷（5.37%）下降至2024年的2,664.36公顷（2.39%），而居民点面积同期从1,182.60公顷（1.42%）扩张至5,119.22公顷（4.61%）。农田面积从39.23%增至41.09%，表明自然生态系统持续向农业和城市用途转化。交叉列联表分析进一步表明，湿地和农田大量转变为居民点用地，证实城市扩张已成为马库尔迪湿地退化的主要驱动因素。分类精度评估的总体精度为72.15%至75.93%，Kappa系数在0.60至0.68之间，表明分类图对于土地利用变化分析具有足够的可靠性。研究认为，快速城市化显著加剧了湿地丧失和破碎化，并日益侵占农业用地，对生态系统可持续性、生物多样性保护","Hensard Journal of Environment","2026-09-20T00:00:00Z",56,{"impact":97,"substance":156,"depth":222,"authority":47,"freshness":223,"relevant":62,"comment":224},15,9,"基于Landsat遥感与GIS的尼日利亚湿地退化实证研究，数据扎实但属区域案例，公共影响有限。",[226],{"name":218,"url":215},[228,21,22,229,230],"粮食安全","城市化","湿地保护",{"code":54,"slug":232,"name":233,"path":234,"parent_code":235},"gis","GIS与空间分析","\u002Ftopic\u002Fdigital-agriculture\u002Fgis","I",[237],{"code":26,"slug":27,"name":28,"path":29,"parent_code":30},{"status":33,"locked":14,"version":34,"method":35,"evidence":239},{"candidates":240,"agricultural_evidence":40},[241,248,252,256],{"code":54,"score":223,"supported":40,"title":242,"abstract":243,"tags":247},[],[244,245,246],"地理信息","GIS","geographic information",[],{"code":26,"score":97,"supported":40,"title":249,"abstract":250,"tags":251},[],[43,27],[22,230],{"code":61,"score":39,"supported":40,"title":253,"abstract":254,"tags":255},[],[177,178],[21],{"code":257,"score":258,"supported":40,"title":259,"abstract":260,"tags":262},"A8",4,[],[261],"food security",[228],[264,265],"Makurdi 湿地 城市化","Benue State 遥感","Makurdi湿地城市化-3069",2,"10.65757\u002Fhjev1n22",{"doi":268,"openalex_id":270,"authors":271,"venue":218,"cited_by_count":15,"oa_url":215,"card":286,"direction":81,"ingested_from":83},"W7213745048",[272,274,276,278,280,282,284],{"name":273,"orcid":9},"Joy Iganya Agene",{"name":275,"orcid":9},"Onoja Sunday",{"name":277,"orcid":9},"Akintunde Elijah",{"name":279,"orcid":9},"Ugese Ayangeaor Andrew",{"name":281,"orcid":9},"Kebiru Umoru",{"name":283,"orcid":9},"Aku Umaku Esther",{"name":285,"orcid":9},"Ombugu Gideon",{"tldr":287,"method":288,"finding":289,"direction":81,"opportunity":290},"用遥感与GIS评估尼日利亚马库尔迪20年间城市化对湿地和农业用地的侵占影响。","Landsat 7\u002F8\u002F9影像，监督分类、变化检测与交叉表分析，GPS实地验证。","湿地占比由5.37%降至2.39%，建设用地由1.42%升至4.61%，城市化是湿地退化主因。","可结合多源高分辨率遥感与CA-Markov模型，预测湿地-农田-城市冲突并支撑国土空间优化。","2026-09-21T23:30:24.084401Z",{"id":293,"title":294,"url":295,"summary":296,"summary_zh":297,"content":9,"source_name":298,"source_url":295,"published_at":299,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":15,"score_detail":300,"sources":302,"tags":304,"primary_topic":307,"secondary_topics":308,"classification":309,"search_phrases":351,"slug":354,"view_count":55,"doi":355,"paper":356,"created_at":370},2434,"Integrated geoenvironmental analysis of the Gandu River sub-basin (Bahia, Brazil): interactions among landscape, water resources, and Atlantic Forest conservation","https:\u002F\u002Fdoi.org\u002F10.55905\u002Frdelosv19.n86-003","Drainage basins are fundamental units for integrated environmental studies, as they represent complex systems in which physical, biological, and socioeconomic components establish interdependent relationships that shape landscape organization and functioning. In this context, this research aims to conduct an integrated geoenvironmental analysis of the Gandu River sub-basin, located in the municipalities of Gandu, Nova Ibiá, and Wenceslau Guimarães, in the state of Bahia, Brazil, within the phytogeographic domain of the Atlantic Forest. The investigation is based on a systemic approach, the geosystem perspective, and the principles of Landscape Ecology, considering the relationships between natural elements and forms of land use and territorial occupation. The methodological procedures involved bibliographic research, cartographic analysis, geoprocessing techniques in a GIS environment, and the preparation of thematic maps related to location, geology, geomorphology, hypsometry, slope, pedology, drainage network, land use and land cover, and the Normalized Difference Vegetation Index (NDVI). The results show that the environmental dynamics of the sub-basin are directly related to geological, geomorphological, pedological, and hydrological characteristics, which influence infiltration processes, surface runoff, and the distribution of vegetation cover. A predominance of areas associated with secondary vegetation and agroforestry systems was observed, especially the cacao-cabruca system, which is important for maintaining regional ecological connectivity. However, landscape fragmentation resulting from the expansion of agricultural and livestock activities and changes in land use represents a threat to biodiversity conservation and the stability of environmental systems. Therefore, integrated geoenvironmental analysis is a fundamental tool for supporting land-use planning strategies, water resource conservation, recovery of degraded areas, and the implementation of ecological corridors in the context of the Atlantic Forest of Bahia.","流域是综合环境研究的基本单元，因其代表了物理、生物和社会经济组分之间建立相互依存关系、塑造景观组织与功能的复杂系统。在此背景下，本研究旨在对位于巴西巴伊亚州甘杜、新伊比亚和文塞斯劳·吉马良斯市境内、地处大西洋森林植物地理区的甘杜河子流域进行综合地质环境分析。调查基于系统方法、地质系统视角和景观生态学原理，考量自然要素与土地利用及领土占用形式之间的关系。方法程序包括文献研究、制图分析、GIS环境下的地理处理技术，以及编制与位置、地质、地貌、高程、坡度、土壤、水系网络、土地利用与土地覆盖、归一化植被指数（NDVI）相关的专题地图。结果表明，子流域的环境动态与地质、地貌、土壤和水文特征直接相关，这些特征影响入渗过程、地表径流和植被覆盖分布。观测到与次生植被和农林复合系统相关的区域占主导地位，尤其是可可-卡布鲁卡系统，其对维持区域生态连通性具有重要意义。然而，农业和畜牧业活动扩张及土地利用变化导致的景观破碎化，对生物多样性保护和环境系统稳定性构成威胁。因此，综合地质环境分析是支持土地利用规划策略、水资源保护、退化区域恢复以及巴伊亚大西洋森林背景下生态廊道实施的基础工具。","DELOS Desarrollo Local Sostenible","2026-09-11T00:00:00Z",{"impact":15,"substance":15,"depth":15,"authority":15,"freshness":15,"relevant":15,"comment":301},"巴西流域地质环境与景观生态研究，属自然地理与生态保护范畴，与三农、农业信息化、智慧农业无直接关联，不建议进入每日精选。",[303],{"name":298,"url":295},[305,21,22,306],"生态保护","流域治理",{"code":26,"slug":27,"name":28,"path":29,"parent_code":30},[],{"status":33,"locked":14,"version":34,"method":35,"evidence":310},{"candidates":311,"agricultural_evidence":40},[312,316,323,330,337,343,347],{"code":26,"score":97,"supported":40,"title":313,"abstract":314,"tags":315},[],[43,27],[22,305],{"code":317,"score":47,"supported":40,"title":318,"abstract":319,"tags":322},"B3",[],[320,321],"可可","cacao",[],{"code":324,"score":47,"supported":40,"title":325,"abstract":326,"tags":329},"C",[],[327,328],"畜牧","livestock",[],{"code":331,"score":47,"supported":40,"title":332,"abstract":333,"tags":336},"H3",[],[334,335],"水资源","water resource",[],{"code":338,"score":55,"supported":40,"title":339,"abstract":340,"tags":342},"H2",[],[341],"土壤",[],{"code":54,"score":55,"supported":40,"title":344,"abstract":345,"tags":346},[],[245],[],{"code":61,"score":62,"supported":14,"title":348,"abstract":349,"tags":350},[],[],[21],[352,353],"土地利用 流域治理 生态保护 遥感监测","土地利用 流域治理","土地利用流域治理生态保护遥感监测-2434","10.55905\u002Frdelosv19.n86-003",{"doi":355,"openalex_id":357,"authors":358,"venue":298,"cited_by_count":15,"oa_url":364,"card":365,"direction":81,"ingested_from":83},"W7212359574",[359,361],{"name":360,"orcid":9},"Ariel Moura Vilas Boas",{"name":362,"orcid":363},"Marcelo Araújo da Nóbrega","https:\u002F\u002Forcid.org\u002F0000-0002-8532-0630","https:\u002F\u002Fojs.revistadelos.com\u002Fojs\u002Findex.php\u002Fdelos\u002Farticle\u002Fdownload\u002F10122\u002F5532",{"tldr":366,"method":367,"finding":368,"direction":81,"opportunity":369},"对巴西Gandu河子流域进行综合地质环境分析，评估景观、水资源与大西洋森林保护的关系。","系统方法与景观生态学视角，结合GIS空间分析、专题制图及NDVI。","次生植被与可可农林系统维持生态连通性，但农牧扩张导致景观破碎化威胁保护。","可结合多时相遥感与景观指数，量化农林复合系统对流域水文与连通性的动态影响。","2026-09-14T23:30:27.425323Z",{"id":372,"title":373,"url":374,"summary":375,"summary_zh":376,"content":9,"source_name":377,"source_url":374,"published_at":378,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":379,"score_detail":380,"sources":384,"tags":386,"primary_topic":390,"secondary_topics":394,"classification":396,"search_phrases":414,"slug":417,"view_count":15,"doi":418,"paper":419,"created_at":438},5392,"Wetland Loss Associated with Hydro-Agricultural Development in North African Floodplains: Insights from a Historical Cartographic Analysis of the Gharb Plain (Morocco)","https:\u002F\u002Fdoi.org\u002F10.3390\u002Fd18100642","Mediterranean floodplain wetlands are among the most productive ecosystems, yet they are increasingly threatened by agricultural intensification and hydrological modifications. In North Africa, most of these wetlands have been converted to agricultural lands using an extensive ‘drainage–irrigation’ process that has irreversibly degraded them. This study documents this loss through the illustrative example of the Gharb Plain in the northwest of Morocco. The agricultural development process of this plain, initiated in 1927 and only recently completed, is documented by both historical maps and remote sensing data, which we combined to reconstruct the simultaneous wetland decline and agriculture extension. The results reveal a dramatic decline in marshland ecosystems, covering about 88% of the original marshlands in less than one cycle. Several wetlands, including large ones, have entirely disappeared, particularly within the Sebou and Baht river floodplains. To ensure their human occupation, the drainage process and river canalization have been supported by a large program of dam construction upstream of the Gharb Plain. The wetland loss estimate highlights the substantial ecological costs of agricultural intensification and underscores the need for integrated management strategies balancing food production and patrimony conservation. Future research should focus on wetland restoration, ecosystem service assessment, and climate-resilient water management in Mediterranean floodplains.","地中海洪泛平原湿地是最具生产力的生态系统之一，却日益受到农业集约化与水文改造的威胁。在北非，大多数此类湿地已通过大规模的“排水—灌溉”过程被转变为农业用地，并因此遭到不可逆的退化。本研究以摩洛哥西北部加尔卜平原（Gharb Plain）为例，记录了这一丧失过程。该平原的农业开发进程始于1927年，直至近期才告完成，我们结合历史地图与遥感数据，重建了湿地衰退与农业扩张同步发生的过程。结果表明，沼泽生态系统急剧减少，在不到一个周期内约88%的原生沼泽地消失。包括大型湿地在内的多处湿地已完全消失，尤其是在塞布河（Sebou）与巴赫特河（Baht）洪泛平原内。为保障人类占用，排水过程与河流渠化得到了加尔卜平原上游大规模水坝建设计划的支持。湿地丧失的估算凸显了农业集约化所带来的巨大生态代价，并强调需要制定兼顾粮食生产与遗产保护的综合管理策略。未来研究应聚焦于湿地恢复、生态系统服务评估以及地中海洪泛平原的气候韧性水资源管理。","Diversity","2026-10-19T00:00:00Z",76,{"impact":157,"substance":381,"depth":156,"authority":382,"freshness":97,"relevant":62,"comment":383},21,13,"该研究结合历史地图与遥感数据，量化了北非洪泛平原湿地因农业开发而丧失的情况，方法扎实、结论明确，对农业生态与土地管理有参考价值，但属区域性案例研究，公共影响有限。",[385],{"name":377,"url":374},[387,21,388,389,230],"生态修复","灌溉农业","土地利用变化",{"code":331,"slug":391,"name":392,"path":393,"parent_code":30},"irrigation","水资源与灌溉","\u002Ftopic\u002Fenvironment\u002Firrigation",[395],{"code":26,"slug":27,"name":28,"path":29,"parent_code":30},{"status":33,"locked":14,"version":34,"method":35,"evidence":397},{"candidates":398,"agricultural_evidence":40},[399,404,410],{"code":331,"score":13,"supported":40,"title":400,"abstract":401,"tags":403},[],[402,334,391],"灌溉",[388],{"code":26,"score":223,"supported":40,"title":405,"abstract":406,"tags":409},[],[407,408],"生态系统服务","ecosystem service",[389,230,387],{"code":61,"score":39,"supported":40,"title":411,"abstract":412,"tags":413},[],[177,178],[21],[415,416],"Gharb平原 湿地 遥感","摩洛哥 湿地 灌溉","Gharb平原湿地遥感-5392","10.3390\u002Fd18100642",{"doi":418,"openalex_id":420,"authors":421,"venue":377,"cited_by_count":15,"oa_url":374,"card":433,"direction":81,"ingested_from":83},"W7222966485",[422,425,427,430],{"name":423,"orcid":424},"Mohamed Dakki","https:\u002F\u002Forcid.org\u002F0000-0002-8042-3972",{"name":426,"orcid":9},"Said El Falah",{"name":428,"orcid":429},"Ibrahim Makrane","https:\u002F\u002Forcid.org\u002F0009-0002-9201-206X",{"name":431,"orcid":432},"Ismail Mansouri","https:\u002F\u002Forcid.org\u002F0000-0002-3679-6050",{"tldr":434,"method":435,"finding":436,"direction":81,"opportunity":437},"用历史地图与遥感重建摩洛哥Gharb平原1927年以来的湿地丧失与农业扩张过程。","历史地图与遥感数据结合，重建湿地退缩与农田扩张的时空过程。","不到一个开发周期内约88%的原生沼泽消失，大型湿地完全丧失。","可延伸至地中海洪泛平原湿地恢复优先区识别与生态系统服务权衡研究。","2026-10-20T23:30:19.135602Z",{"id":440,"title":441,"url":442,"summary":443,"summary_zh":444,"content":9,"source_name":445,"source_url":442,"published_at":446,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":447,"score_detail":448,"sources":450,"tags":452,"primary_topic":454,"secondary_topics":455,"classification":457,"search_phrases":479,"slug":482,"view_count":15,"doi":483,"paper":484,"created_at":505},5096,"Land Cover Change, Ecosystem Service Implications, and Economy–Land Use Decoupling:","https:\u002F\u002Fdoi.org\u002F10.14246\u002Firspsd.14.4_186","Land cover change plays a critical role in shaping watershed ecological conditions and supporting regional economic activities. This study analyzes land cover dynamics in the Tiworo Watershed, Southeast Sulawesi, Indonesia, for 2014, 2019, and 2024, and examines their relationship with sectoral economic growth. Remote sensing and GIS were used to map and quantify land cover changes, while sectoral Gross Regional Domestic Product (GRDP) data for agriculture, forestry, and fisheries represented economic performance. Economy–land use interactions were assessed using the Tapio decoupling elasticity index. Economy–land use interactions were assessed using the Tapio decoupling elasticity index as a retrospective empirical measure based on observed changes in land cover and sectoral GRDP over the study periods. The results show increasing sectoral GRDP accompanied by relatively limited changes in dominant land cover classes. Absolute decoupling was observed during 2014–2019, relative decoupling during 2019–2024, and overall absolute decoupling for 2014–2024, indicating that economic growth was not proportionally associated with large-scale land conversion. Spatial analysis reveals localized landscape transformations, including mangrove degradation, settlement expansion, and plantation growth, which signal emerging pressures on environmentally sensitive areas. Although ecosystem services are not directly valued, land cover change is interpreted as an indicator of ecological pressure with implications for provisioning ecosystem services. These findings highlight the importance of integrating land-use monitoring and economic indicators to support adaptive watershed management, spatial planning, and sustainable development.","土地覆盖变化在塑造流域生态状况和支撑区域经济活动方面发挥着关键作用。本研究分析了印度尼西亚东南苏拉威西省蒂沃罗流域（Tiworo Watershed）2014年、2019年和2024年的土地覆盖动态，并考察其与部门经济增长的关系。研究采用遥感和地理信息系统（GIS）对土地覆盖变化进行制图和量化，同时以农业、林业和渔业的部门地区生产总值（GRDP）数据表征经济表现。经济与土地利用的相互作用采用Tapio脱钩弹性指数进行评估，该指数作为基于研究期内观测到的土地覆盖变化和部门GRDP变化的回顾性经验测度。结果表明，部门GRDP持续增长，而主导土地覆盖类型的变化相对有限。2014—2019年呈现绝对脱钩，2019—2024年呈现相对脱钩，2014—2024年整体呈现绝对脱钩，表明经济增长与大规模土地转换之间不存在比例关联。空间分析揭示了局部景观转型，包括红树林退化、居民点扩张和种植园增长，这些信号表明环境敏感区域正面临新兴压力。尽管生态系统服务未被直接估值，但土地覆盖变化被解释为生态压力的指标，并对供给型生态系统服务具有潜在影响。这些发现凸显了整合土地利用监测与经济指标的重要性，以支持适应性流域管理、空间规划和可持续发展。","International Review for Spatial Planning and Sustainable Development","2026-10-14T00:00:00Z",63,{"impact":97,"substance":156,"depth":157,"authority":382,"freshness":97,"relevant":62,"comment":449},"基于遥感与GIS的流域土地利用变化与经济增长脱钩研究，方法规范但属区域案例，对国内三农信息化参考价值有限。",[451],{"name":445,"url":442},[21,389,453,407,164],"流域管理",{"code":26,"slug":27,"name":28,"path":29,"parent_code":30},[456],{"code":54,"slug":232,"name":233,"path":234,"parent_code":235},{"status":33,"locked":14,"version":34,"method":35,"evidence":458},{"candidates":459,"agricultural_evidence":40},[460,464,469,473],{"code":26,"score":382,"supported":40,"title":461,"abstract":462,"tags":463},[408],[407],[389,407],{"code":54,"score":13,"supported":40,"title":465,"abstract":466,"tags":468},[],[244,58,245,467],"spatial analysis",[164],{"code":61,"score":39,"supported":40,"title":470,"abstract":471,"tags":472},[],[177,178],[21],{"code":474,"score":55,"supported":40,"title":475,"abstract":476,"tags":478},"D",[],[477],"渔业",[],[480,481],"Tiworo流域 土地利用 遥感","Tapio脱钩 农业经济 土地覆盖","Tiworo流域土地利用遥感-5096","10.14246\u002Firspsd.14.4_186",{"doi":483,"openalex_id":485,"authors":486,"venue":445,"cited_by_count":15,"oa_url":499,"card":500,"direction":81,"ingested_from":83},"W7221789653",[487,490,493,496],{"name":488,"orcid":489},"Safril Kasim","https:\u002F\u002Forcid.org\u002F0009-0009-4679-4233",{"name":491,"orcid":492},"Hasddin Hasddin","https:\u002F\u002Forcid.org\u002F0000-0002-0114-5274",{"name":494,"orcid":495},"La Fariki","https:\u002F\u002Forcid.org\u002F0009-0003-7870-9028",{"name":497,"orcid":498},"Abhishek Agarwal","https:\u002F\u002Forcid.org\u002F0000-0002-0900-6383","https:\u002F\u002Fwww.jstage.jst.go.jp\u002Farticle\u002Firspsd\u002F14\u002F4\u002F14_9\u002F_pdf",{"tldr":501,"method":502,"finding":503,"direction":81,"opportunity":504},"分析印尼Tiworo流域2014-2024年土地覆盖变化与部门经济增长的脱钩关系。","遥感与GIS制图，结合GRDP数据和Tapio脱钩弹性指数。","经济持续增长但土地覆盖变化有限，整体呈绝对脱钩，局部红树林退化等生态压力显现。","可将脱钩指数与生态系统服务价值核算结合，量化流域生态压力并支撑空间规划。","2026-10-16T23:30:28.687070Z"]
