The purpose of this research was to explore the Spatio-temporal pattern of urban expansion and changes in land use\u002Fland cover (LULC) in Sargodha Tehsil, Pakistan, for the period 2000-2025. This study used the remote sensing and GIS techniques to analyze the satellite imageries of 6 years. These years include 2000, 2005, 2010, 2015, 2020 and 2025. The study area covered an expanse of 1536 km² and comprised four land use\u002Fland cover (LULC) classes, including agricultural land, built-up area, barren land, and water bodies. The study used supervised classification Maximum likelihood classifier (MLC) to identify the dominant land use and land cover types and determine the percentage of the region that was covered by each class. The results show that there is a growing trend in the built-up area throughout the years. It increased from 115 km² in 2000 to 180 km² in 2005, 233 km² in 2010, 297 km² in 2015, 361 km² in 2020, and 440 km² in 2025. Thus, it can be stated that there was an increase in the built-up area by 325 km² or 282.6% over the studied period. In contrast, the amount of farmland decreased from 1,014 km² to 815 km² or 199 km². The area of barren land decreased as well from 280 km² to 153 km². At the same time, there was no significant change in the amount of water bodies from 127 km² to 128 km². Findings reveal a significant change from a primarily agricultural region to a region with a considerable presence of developed areas and emphasize the increasing pressure on productive land. The research underlines the significance of planned urbanization, protection of productive agricultural lands, regular geospatial monitoring, and appropriate management of the periphery belt.","城市增长是许多快速发展的城市正在经历的重要土地利用转变，尤其是在生产力较高的农业用地上发生扩张的地区。本研究旨在探讨巴基斯坦萨戈达县（Sargodha Tehsil）2000—2025年期间城市扩张的时空格局及土地利用\u002F土地覆盖（LULC）变化。本研究采用遥感与GIS技术，对6个年份的卫星影像进行了分析，包括2000年、2005年、2010年、2015年、2020年和2025年。研究区面积为1536 km²，涵盖四种土地利用\u002F土地覆盖（LULC）类型，包括农业用地、建设用地、裸地和水体。研究采用监督分类中的最大似然分类器（MLC）识别主要土地利用与土地覆盖类型，并确定各类型所占区域百分比。结果表明，建设用地面积在各年份间呈持续增长趋势，从2000年的115 km²增至2005年的180 km²、2010年的233 km²、2015年的297 km²、2020年的361 km²，以及2025年的440 km²。因此可以认为，在研究期间建设用地面积增加了325 km²，增幅达282.6%。相比之下，农田面积从1014 km²减少至815 km²，减少了199 km²。裸地面积也从280 km²减少至153 km²。与此同时，水体面积从127 km²变化至128 km²，没有显著变化。研究结果揭示了该区域从以农业为主向建设用地显著增加的区域发生了重大转变，并凸显了生产性土地日益增大的压力。本研究强调了有计划城市化、保护生产性农业用地、定期地理空间监测以及对外围地带进行适当管理的重要性。",null,"Journal of Global Social Transformation","2026-09-17T00:00:00Z","论文",10,false,55,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},8,18,14,6,9,1,"基于遥感与GIS的巴基斯坦城市扩张对农用地影响研究，数据翔实但属区域案例，对国内三农信息化参考价值有限。",[25],{"name":10,"url":6},[27,28,29,30,31],"耕地保护","遥感监测","土地利用","GIS","城市扩张",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},"I3","remote-sensing","遥感与农情监测","\u002Ftopic\u002Fdigital-agriculture\u002Fremote-sensing","I",[],{"status":40,"locked":14,"version":41,"method":42,"evidence":43},"classified","2026-10-22.2","rules",{"candidates":44,"agricultural_evidence":47},[45,53,59,64],{"code":33,"score":46,"supported":47,"title":48,"abstract":49,"tags":52},7,true,[],[50,51],"遥感","remote sensing",[28],{"code":54,"score":55,"supported":47,"title":56,"abstract":57,"tags":58},"I4",4,[],[30],[30],{"code":60,"score":22,"supported":14,"title":61,"abstract":62,"tags":63},"H1",[],[],[27],{"code":65,"score":22,"supported":14,"title":66,"abstract":67,"tags":68},"H6",[],[],[29],[70,71],"土地利用 城市扩张 耕地保护 遥感监测","土地利用 城市扩张","土地利用城市扩张耕地保护遥感监测-2784",2,"10.71317\u002Fjgst.2.9(s).2026.624",{"doi":74,"openalex_id":76,"authors":77,"venue":10,"cited_by_count":88,"oa_url":6,"card":89,"direction":93,"ingested_from":95},"W7213443079",[78,80,83,85],{"name":79,"orcid":9},"Muhammad Israr",{"name":81,"orcid":82},"Omar Riaz","https:\u002F\u002Forcid.org\u002F0000-0002-5391-109X",{"name":84,"orcid":9},"Muhammad Safeer Hussain",{"name":86,"orcid":87},"Muhammad Imran","https:\u002F\u002Forcid.org\u002F0000-0003-4072-4997",0,{"tldr":90,"method":91,"finding":92,"direction":93,"opportunity":94},"用遥感与GIS分析巴基斯坦萨戈达2000-2025年城市扩张及土地利用变化。","6期Landsat影像，最大似然监督分类，提取四类LULC并统计面积。","建设用地增325km²（282.6%），耕地减199km²，城市扩张大量侵占优质农田。","农业遥感与作物表型","可结合耕地质量与作物生产力数据，量化城市扩张对农业产能的具体损失并构建预警模型。","openalex","2026-09-17T23:30:34.285631Z",{"total":20,"page":22,"page_size":20,"items":98},[99,168,212,259,319,384],{"id":100,"title":101,"url":102,"summary":103,"summary_zh":104,"content":9,"source_name":105,"source_url":102,"published_at":106,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":88,"score_detail":107,"sources":109,"tags":111,"primary_topic":112,"secondary_topics":113,"classification":118,"search_phrases":146,"slug":149,"view_count":21,"doi":150,"paper":151,"created_at":167},3071,"Urban Influence on Landscape Transformation and Land Cover Interactions During Urban Expansion (1972–2022): A Remote Sensing and GIS-Based Analysis","https:\u002F\u002Fdoi.org\u002F10.2478\u002Fjlecol-2026-0038","Abstract This study investigates how urban expansion influences land cover dynamics. An interactive analytical approach was adopted to examine the transitions among built-up areas, cropland, and bare land throughout the urbanization process. Remote Sensing and GIS techniques, in conjunction with the Land Transfer Matrix (LTM), Landscape Metrics (LM), Multi-buffer Ring (MBR) and complementary spatial tools, were employed to analyze the city of Tiaret in Algeria over the past half century (1972-2022). The results reveal a marked intensification of urbanization, with an Overall Average Annual Urban Expansion Rate (OA-AUER) of 28.3 ha and a concurrent rise in bare land driven by cropland conversion under urban pressure. Notably, 89.4 % of cropland loss initially transitions into bare land, while subsequent urban development originates from cropland (52 %) and bare land (47 %). The observed density patterns in peripheral areas confirm the significant influence of the urban core on surrounding land-cover transformations. These findings elucidate the urbanization process while considering the transitional role of bare land and further explain diffusion coalescence process. Further empirical research is recommended to refine theoretical frameworks on landscape transformation dynamics and to inform policies aimed at mitigating bare-land expansion in peri-urban areas, controlling cropland urbanization, and planning sustainable urban growth.","摘要 本研究探讨城市扩张如何影响土地覆盖动态。采用交互式分析方法，考察城市化进程中建成区、耕地和裸地之间的转换。运用遥感与地理信息系统技术，结合土地转移矩阵（LTM）、景观格局指数（LM）、多缓冲环（MBR）及辅助空间工具，对阿尔及利亚提亚雷特市过去半个世纪（1972—2022年）的变化进行了分析。结果表明，城市化显著加剧，年均城市扩张总面积率（OA-AUER）为28.3公顷，同时在城市压力下耕地转换导致裸地同步增加。值得注意的是，89.4%的耕地损失最初转变为裸地，而随后的城市发展来源于耕地（52%）和裸地（47%）。外围区域观测到的密度格局证实了城市核心对周边土地覆盖变化的显著影响。这些发现阐明了城市化过程，同时考虑了裸地的过渡性作用，并进一步解释了扩散聚合过程。建议开展进一步实证研究，以完善景观转型动态的理论框架，并为旨在减缓城郊地区裸地扩张、控制耕地城市化以及规划可持续城市增长的政策提供依据。","Journal of Landscape Ecology","2026-09-19T00:00:00Z",{"impact":88,"substance":88,"depth":88,"authority":88,"freshness":88,"relevant":88,"comment":108},"该论文聚焦阿尔及利亚Tiaret市城市扩张与土地覆盖变化，属城市地理与遥感应用研究，与三农、农业信息化、智慧农业主题无直接关联，不建议进入每日精选。",[110],{"name":105,"url":102},[27,28,29,31],{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[114],{"code":54,"slug":115,"name":116,"path":117,"parent_code":37},"gis","GIS与空间分析","\u002Ftopic\u002Fdigital-agriculture\u002Fgis",{"status":40,"locked":14,"version":41,"method":42,"evidence":119},{"candidates":120,"agricultural_evidence":47},[121,126,131,138,142],{"code":33,"score":122,"supported":47,"title":123,"abstract":124,"tags":125},15,[51],[50,51],[28],{"code":54,"score":19,"supported":47,"title":127,"abstract":128,"tags":130},[30],[129,30],"地理信息",[],{"code":132,"score":133,"supported":47,"title":134,"abstract":135,"tags":137},"G2",3,[],[136],"land transfer",[],{"code":60,"score":22,"supported":14,"title":139,"abstract":140,"tags":141},[],[],[27],{"code":65,"score":22,"supported":14,"title":143,"abstract":144,"tags":145},[],[],[29],[147,148],"Tiaret 城市扩张 遥感","耕地 建设用地 转移矩阵","Tiaret城市扩张遥感-3071","10.2478\u002Fjlecol-2026-0038",{"doi":150,"openalex_id":152,"authors":153,"venue":105,"cited_by_count":88,"oa_url":161,"card":162,"direction":93,"ingested_from":95},"W7213652939",[154,156,158],{"name":155,"orcid":9},"Amina Kalbaza",{"name":157,"orcid":9},"Belkacem Marir",{"name":159,"orcid":160},"Farida Naceur","https:\u002F\u002Forcid.org\u002F0009-0004-1962-4937","https:\u002F\u002Freference-global.com\u002Fdownload\u002Farticle\u002F10.2478\u002Fjlecol-2026-0038.pdf",{"tldr":163,"method":164,"finding":165,"direction":93,"opportunity":166},"基于遥感与GIS分析阿尔及利亚提亚雷特1972—2022年城市扩张对景观与土地覆盖的影响。","遥感、GIS、土地转移矩阵、景观格局指数与多缓冲环分析。","耕地先转为裸地再被城市占用，城市核心显著驱动外围土地覆盖转变。","可延伸研究裸地作为耕地—城市转换中间态的机制，并构建城郊耕地流失预警模型。","2026-09-21T23:30:24.332177Z",{"id":169,"title":170,"url":171,"summary":172,"summary_zh":173,"content":9,"source_name":174,"source_url":171,"published_at":175,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":88,"score_detail":176,"sources":178,"tags":180,"primary_topic":181,"secondary_topics":182,"classification":183,"search_phrases":194,"slug":197,"view_count":88,"doi":198,"paper":199,"created_at":211},5094,"An Investigation of Built-up Area Expansion in the Syrian Coastal Mountain Environment","https:\u002F\u002Fdoi.org\u002F10.14246\u002Firspsd.14.4_109","As built-up expansion in the Syrian coastal mountainous areas intensifies, its environmental impacts are becoming increasingly severe. Existing research, however, offers limited quantitative evidence to elucidate the dynamics of this phenomenon. This study addresses this gap by employing mixed-method techniques at the district level of Safita. Landsat satellite imagery, remote sensing, and ArcGIS software were used to classify and analyze geospatial data from 2010 to 2020. Statistical methodologies were then applied to investigate spatio-temporal built-up growth, identify the drivers of expansion, and evaluate resultant spatial patterns. The analysis reveals accelerated built-up expansion, with the most dramatic growth occurring in southern peripheral zones, recording increases of 150-169%. The study identifies a persistent trend of low-density, dispersed sprawl following a non-linear trajectory, evidenced by Shannon's entropy increasing steadily to 0.89 by 2020. Analysis of Urban Expansion Rate and Intensity indices shows a distinct shift from moderate, semi-efficient growth (2010–2015) to rapid and extensive sprawl (2015–2020). Furthermore, the Built-up Expansion Index demonstrates an evolution from initial economically driven leapfrog expansion through conflict-induced infilling consolidation to a final hybrid pattern combining edge-expansion and ribbon development. Kernel Density Estimation reveals a fundamental spatial transformation from semi-concentrated hotspots to widespread medium-density sprawl, strongly constrained by physical factors. Specifically, 93% of built-up areas concentrated on gentle slopes (0-15%), and 68% were located within 200 meters of road networks. These findings underscore the urgent need for planning decision-makers to implement strict regulatory measures that curb built-up sprawl, protect agricultural lands and natural resources, and guide growth through updated master plans to achieve sustainable development.","随着叙利亚沿海山区建成区扩张不断加剧，其环境影响日益严重。然而，现有研究在阐明这一现象的动态方面提供的定量证据有限。本研究通过在萨菲塔区级层面采用混合方法技术来填补这一空白。利用Landsat卫星影像、遥感技术和ArcGIS软件对2010年至2020年的地理空间数据进行分类和分析。随后应用统计方法研究建成区的时空增长，识别扩张的驱动因素，并评估由此产生的空间格局。分析揭示了建成区扩张的加速，最显著的增长发生在南部边缘地带，增幅达150%至169%。研究识别出低密度、分散式蔓延的持续趋势，呈非线性轨迹，香农熵（Shannon's entropy）到2020年稳步上升至0.89即为明证。城市扩张速率和强度指数的分析显示，从2010至2015年的温和、半高效增长明显转向2015至2020年的快速、广泛蔓延。此外，建成区扩张指数（Built-up Expansion Index）表明，扩张从最初经济驱动的跳跃式扩展，经过冲突引发的填充式整合，演变为边缘扩展与带状发展相结合的最终混合模式。核密度估计（Kernel Density Estimation）揭示了从半集中热点向广泛中密度蔓延的根本性空间转变，且受自然因素的强烈制约。具体而言，93%的建成区集中在缓坡（0-15%）上，68%位于道路网络200米范围内。这些发现凸显了规划决策者迫切需要实施严格的监管措施，以遏制建成区蔓延，保护农田和自然资源，并通过更新总体规划引导增长，以实现可持续发展。","International Review for Spatial Planning and Sustainable Development","2026-10-14T00:00:00Z",{"impact":88,"substance":88,"depth":88,"authority":88,"freshness":88,"relevant":88,"comment":177},"研究叙利亚沿海山区建成区扩张，属城市规划与环境领域，与三农、农业信息化、数字乡村无关。",[179],{"name":174,"url":171},[28,29,31],{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":184},{"candidates":185,"agricultural_evidence":47},[186,190],{"code":33,"score":46,"supported":47,"title":187,"abstract":188,"tags":189},[],[50,51],[28],{"code":65,"score":22,"supported":14,"title":191,"abstract":192,"tags":193},[],[],[29],[195,196],"叙利亚沿海山区 建成区扩张","Safita 遥感 土地利用","叙利亚沿海山区建成区扩张-5094","10.14246\u002Firspsd.14.4_109",{"doi":198,"openalex_id":200,"authors":201,"venue":174,"cited_by_count":88,"oa_url":205,"card":206,"direction":93,"ingested_from":95},"W7221786958",[202],{"name":203,"orcid":204},"Tarek Rahmoun","https:\u002F\u002Forcid.org\u002F0000-0001-5112-2487","https:\u002F\u002Fwww.jstage.jst.go.jp\u002Farticle\u002Firspsd\u002F14\u002F4\u002F14_6\u002F_pdf",{"tldr":207,"method":208,"finding":209,"direction":93,"opportunity":210},"研究叙利亚沿海山区萨菲塔地区2010-2020年建设用地扩张动态、驱动因素与空间格局。","Landsat影像、遥感与ArcGIS分类，结合统计方法分析时空扩张。","建设用地加速低密度蔓延，93%集中于缓坡、68%靠近道路，熵值升至0.89。","可结合遥感与机器学习，量化山区建设用地扩张对农地流失和生态的长期影响。","2026-10-16T23:30:28.556800Z",{"id":213,"title":214,"url":215,"summary":216,"summary_zh":217,"content":9,"source_name":218,"source_url":215,"published_at":219,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":88,"score_detail":220,"sources":222,"tags":224,"primary_topic":225,"secondary_topics":226,"classification":227,"search_phrases":242,"slug":244,"view_count":22,"doi":245,"paper":246,"created_at":258},4679,"Spatio-temporal variation of urban sprawl in Tura town using the Shannon entropy model","https:\u002F\u002Fdoi.org\u002F10.5281\u002Fzenodo.23277607","Abstract Urbanization is driving substantial transformation of cities worldwide, with unmanaged expansion often resulting in urban sprawl and the loss of agricultural land, forests, and environmentally sensitive areas.

This study presents a PRISMA-based systematic review combined with bibliometric and thematic synthesis to examine global urban sprawl research. Following structured screening of 183 records, 54 peer-reviewed journal articles were retained for detailed analysis. Bibliometric mapping using VOSviewer, quantitative comparison, and thematic synthesis were integrated to assess methodological evolution, geographic concentration, and sustainability integration. The findings reveal three developmental phases: an early exploratory stage, a consolidation phase dominated by spatial modeling, and a recent shift toward environmental and climaterelated assessment. Methodologically, Cellular Automata and CA–Markov models account for 40.74% of studies, followed by remote sensing change detection (25.93%), while spatial regression approaches remain limited (3.70%). Urban expansion magnitudes show substantial heterogeneity, with a mean built-up growth of 119.7% and a strongly right-skewed distribution (Sk = 1.97; K = 2.38). Reported growth ranges from below 20% to over 500%, frequently associated with agricultural land conversion and land surface temperature intensification. Classification accuracies typically range from 83% to 91%, indicating high technical reliability. Research output is geographically concentrated in Asia (61.11%), particularly in China and India, while governance-oriented scholarship remains comparatively underrepresented. Overlay analysis indicates an emerging focus on climate change and ecosystem impacts, yet institutional evaluation remains peripheral. Overall, the field demonstrates strong technical maturity but limited integration of policy assessment, underscoring the need for cross-scale causal modeling and standardized sustainability metrics.","城市蔓延是当代城市化的主要空间表现形式，重塑了土地系统、生态稳定性和可持续发展轨迹。本研究基于PRISMA框架开展系统综述，并结合文献计量与主题综合分析，考察全球城市蔓延研究。经过对183条记录的结构化筛选，最终保留54篇同行评审期刊论文进行详细分析。研究整合了基于VOSviewer的文献计量图谱、定量比较和主题综合分析，以评估方法论演进、地理集中度和可持续性整合情况。研究结果揭示了三个发展阶段：早期探索阶段、以空间建模为主导的巩固阶段，以及近期向环境与气候相关评估的转向。在方法论上，元胞自动机（Cellular Automata）和CA–Markov模型占研究的40.74%，其次是遥感变化检测（25.93%），而空间回归方法的运用仍然有限（3.70%）。城市扩张幅度呈现显著异质性，建成区平均增长率为119.7%，分布呈强右偏（Sk = 1.97；K = 2.38）。报告的增长范围从低于20%到超过500%，且常与农用地转换和地表温度加剧相关。分类精度通常在83%至91%之间，表明技术可靠性较高。研究成果在地理上集中于亚洲（61.11%），尤其是中国和印度，而面向治理的学术研究相对不足。叠加分析表明，气候变化和生态系统影响正成为新兴关注焦点，但制度评估仍处于边缘地位。总体而言，该领域展现出较强的技术成熟度，但政策评估的整合有限，凸显了跨尺度因果建模和标准化可持续性指标的必要性。","Nature Environment and Pollution Technology","2026-09-28T00:00:00Z",{"impact":88,"substance":88,"depth":88,"authority":88,"freshness":88,"relevant":88,"comment":268},"该文为城市扩张研究的文献计量综述，属城市地理与生态环境领域，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。",[270],{"name":265,"url":262},[272,28,29,31],"文献计量",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":276},{"candidates":277,"agricultural_evidence":47},[278,284,288,295],{"code":279,"score":122,"supported":47,"title":280,"abstract":282,"tags":283},"I7",[281],"bibliometric",[272,281],[272],{"code":33,"score":46,"supported":47,"title":285,"abstract":286,"tags":287},[],[50,51],[28],{"code":289,"score":20,"supported":47,"title":290,"abstract":291,"tags":294},"H7",[],[292,293],"气候变化","climate change",[],{"code":65,"score":22,"supported":14,"title":296,"abstract":297,"tags":298},[],[],[29],[300,71],"土地利用 城市扩张 文献计量 遥感监测","土地利用城市扩张文献计量遥感监测-3774","10.46488\u002Fnept.2026.v25i04.b4435",{"doi":302,"openalex_id":304,"authors":305,"venue":265,"cited_by_count":88,"oa_url":262,"card":311,"direction":317,"ingested_from":95},"W7214666438",[306,309],{"name":307,"orcid":308},"Jaswant Singh","https:\u002F\u002Forcid.org\u002F0009-0003-4653-4972",{"name":310,"orcid":9},"Kranti Kumar Maurya",{"tldr":312,"method":313,"finding":314,"direction":315,"opportunity":316},"基于PRISMA系统综述与文献计量，梳理全球城市蔓延研究的演化阶段、方法分布与地理格局。","PRISMA筛选54篇文献，结合VOSviewer文献计量、定量比较与主题综合。","研究历经三阶段，CA与CA-Markov占40.74%，成果集中于亚洲，政策评估与制度研究薄弱。","农业绿色发展与碳","可结合遥感与因果建模，研究城市蔓延导致的农地转换、地表升温及跨尺度可持续性评估。","智慧农业 \u002F 农业物联网","2026-09-29T23:30:10.523829Z",{"id":320,"title":321,"url":322,"summary":323,"summary_zh":324,"content":9,"source_name":325,"source_url":322,"published_at":326,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":327,"score_detail":328,"sources":330,"tags":332,"primary_topic":335,"secondary_topics":336,"classification":338,"search_phrases":359,"slug":362,"view_count":73,"doi":363,"paper":364,"created_at":383},2943,"SPATIO-TEMPORAL DYNAMICS OF LAND USE AND LAND COVER IN A GRANITE QUARRYING AREA IN MANÉAH, GUINEA: A REMOTE SENSING AND GIS-BASED ANALYSIS FROM 1980 TO 2024","https:\u002F\u002Fdoi.org\u002F10.30574\u002Fgscarr.2026.28.3.0222","Quarrying is a major driver of transformation in peri-urban areas, particularly in spaces experiencing both rapid urbanization and increasing pressure on natural resources. This study analyzes the spatio-temporal dynamics of land cover in the urban commune of Manéah, Guinea, between 1980, 2020, and 2024, in order to characterize the territorial changes associated with the development of extractive activities and urban expansion. The methodological approach relies on the use of multi-temporal satellite imagery, its processing in a GIS environment, supervised classification of the main land cover classes, diachronic analysis of changes, construction of a transition matrix, and evaluation of the quality of the classifications using the Kappa index. The results highlight a profound transformation of the landscape. Between 1980 and 2024, the proportion of built-up areas increased from 7.22% to 32.67%, a rise of 25.45 percentage points, while quarries and construction sites, absent in 1980, represented 2.05% of the territory in 2024, after reaching 7.50% in 2020. Conversely, cultivated land and fallow land increased overall by 18.58 percentage points. In contrast, natural formations experienced a sharp decline: shrub savannas decreased from 40.50% to 1.73%, bodies of water from 31.46% to 11.30%, and mangroves from 8.85% to 0.84%. The Kappa values of 0.76, 0.79, and 0.82 indicate a satisfactory agreement between the classifications. These changes reflect the increasing human impact on the territory, resulting from the combined effects of urbanization, agriculture, and extractive activities. The change matrix also confirms a structural recomposition of the territory, with built-up areas increasing from 963.406 ha to 4,357.55 ha, while shrub savannas decreased from 5,401.819 ha to only 230.389 ha over the entire study period. The study thus highlights the need to further integrate remote sensing data and GIS tools into land-use planning, environmental monitoring, and the spatial management of quarries in Manéah.","采石活动是城郊地区转型的主要驱动力，尤其是在同时经历快速城市化和自然资源压力加剧的区域。本研究分析了几内亚马内阿（Manéah）城市公社在1980年、2020年和2024年的土地覆盖时空动态，以刻画与采掘活动发展和城市扩张相关的领土变化。研究方法依赖于多时相卫星影像的使用、在GIS环境中的处理、主要土地覆盖类别的监督分类、变化的历史对比分析、转移矩阵的构建，以及利用Kappa指数评估分类质量。结果揭示了景观的深刻转变。1980年至2024年间，建成区比例从7.22%增至32.67%，上升了25.45个百分点；而采石场和建筑工地1980年尚不存在，2020年达到7.50%，2024年占领土的2.05%。相反，耕地和休耕地总体增加了18.58个百分点。相比之下，自然 formations 急剧减少：灌木草原从40.50%降至1.73%，水体从31.46%降至11.30%，红树林从8.85%降至0.84%。Kappa值分别为0.76、0.79和0.82，表明分类之间具有令人满意的一致性。这些变化反映了人类对领土日益加剧的影响，这是城市化、农业和采掘活动共同作用的结果。变化矩阵也证实了领土的结构性重组，建成区从963.406公顷增至4，357.55公顷，而灌木草原在整个研究期内从5，401.819公顷降至仅230.389公顷。因此，本研究强调了进一步将遥感数据和GIS工具纳入马内阿的土地利用规划、环境监测和采石场空间管理的必要性。","GSC Advanced Research and Reviews","2026-09-18T00:00:00Z",60,{"impact":17,"substance":18,"depth":122,"authority":13,"freshness":21,"relevant":22,"comment":329},"基于多时相遥感与GIS的矿区土地利用变化研究，方法规范、数据翔实，但地域性强、与国内农业信息化关联有限，可作为遥感应用案例参考。",[331],{"name":325,"url":322},[333,28,29,30,334],"城镇化","矿区生态",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[337],{"code":54,"slug":115,"name":116,"path":117,"parent_code":37},{"status":40,"locked":14,"version":41,"method":42,"evidence":339},{"candidates":340,"agricultural_evidence":47},[341,345,350,355],{"code":33,"score":122,"supported":47,"title":342,"abstract":343,"tags":344},[51],[50,51],[28],{"code":54,"score":346,"supported":47,"title":347,"abstract":348,"tags":349},12,[30],[30],[30],{"code":279,"score":133,"supported":47,"title":351,"abstract":352,"tags":354},[],[353],"研究方法",[],{"code":65,"score":73,"supported":14,"title":356,"abstract":357,"tags":358},[],[],[29,334],[360,361],"Manéah 几内亚 土地利用","遥感 GIS 采石场 土地覆盖","Manéah几内亚土地利用-2943","10.30574\u002Fgscarr.2026.28.3.0222",{"doi":363,"openalex_id":365,"authors":366,"venue":325,"cited_by_count":88,"oa_url":322,"card":378,"direction":93,"ingested_from":95},"W7213550535",[367,369,371,374,376],{"name":368,"orcid":9},"Sogbè KEITA",{"name":370,"orcid":9},"Mamady Minata CONDÉ",{"name":372,"orcid":373},"Ibrahima Thiam","https:\u002F\u002Forcid.org\u002F0000-0001-8553-1043",{"name":375,"orcid":9},"Lucien SOLIE",{"name":377,"orcid":9},"Alpha Issaga Pallé Diallo",{"tldr":379,"method":380,"finding":381,"direction":93,"opportunity":382},"基于遥感与GIS分析几内亚Manéah采石区1980-2024年土地利用与覆盖的时空变化。","多时相卫星影像、GIS监督分类、变化矩阵与Kappa精度评价。","建设用地由7.22%升至32.67%，灌丛草原由40.50%降至1.73%，采石场2024年占2.0","可延伸至采石与城市化对周边农地、红树林的耦合影响及生态修复监测研究。","2026-09-19T23:30:32.836654Z",{"id":385,"title":386,"url":387,"summary":388,"summary_zh":389,"content":9,"source_name":390,"source_url":387,"published_at":391,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":392,"score_detail":393,"sources":397,"tags":399,"primary_topic":402,"secondary_topics":403,"classification":405,"search_phrases":439,"slug":442,"view_count":55,"doi":443,"paper":444,"created_at":456},2319,"Assessing Forest Resource Depletion and Rural Livelihood Sustainability in Ovia Southwest, Nigeria using Remote Sensing, GIS, and Qualitative Socio-Economic Data","https:\u002F\u002Fdoi.org\u002F10.70882\u002Fjosrar.2026.v3i5.278","Forest resources are fundamental to rural livelihoods in sub-Saharan Africa, yet rapid land-use change threatens their sustainability. This study assessed forest cover change, available forest resources, socio-economic drivers of household dependence, and community perceptions of forest contributions to socio-economic development in Ovia Southwest LGA., Edo State, Nigeria. A mixed-methods approach was used to integrate remote sensing and GIS analysis of Landsat imagery (1987–2024), a household survey (n = 390), factor analysis, multiple regression, and chi-square tests. Land use land cover classification revealed that natural environment (forest cover) declined from 76.95% (202,031.28ha) in 1987 to 42.07% (110,449.55ha) in 2024, representing a 50% loss. Disturbed forest increased from 13.48% to 27.80%, while farmland expanded from 6.90% to 26.08%. Factor analysis identified four dominant forest resource categories: timber\u002Fcharcoal\u002Ffibres (35.4% variance), medicinal plants\u002Froots\u002Fforest soil (14.8%), fruits\u002Fanimal fodder (9.9%), and meat\u002Fhoney (7.0%). Multiple regression showed socio-economic factors significantly influenced household forest dependence (R² = 0.279, F = 29.779, p \u003C 0.001), with education, age, and occupation as the strongest predictors. Chi-square analysis confirmed that communities perceive a significant contribution of forest resources to socio-economic development (χ² = 221.718, df = 32, p \u003C 0.001). The study concludes that agricultural expansion and timber extraction are primary drivers of forest degradation, and livelihood diversification interventions are urgently needed to reduce forest dependence while sustaining rural well-being. And recommended implementation of community-participatory forest conservation programmes; investment in rural education\u002Fexpanded vocational training to provide alternative income sources; and regular monitoring using remote sensing should continue to track forest cover trends and inform adaptive management.","森林资源是撒哈拉以南非洲农村生计的基础，但快速的土地利用变化威胁着其可持续性。本研究评估了尼日利亚埃多州奥维亚西南地方政府区的森林覆盖变化、可利用森林资源、家庭依赖的社会经济驱动因素以及社区对森林促进社会经济发展的认知。研究采用混合方法，整合了1987—2024年Landsat影像的遥感与GIS分析、入户调查（n = 390）、因子分析、多元回归和卡方检验。土地利用\u002F土地覆盖分类显示，自然环境（森林覆盖）从1987年的76.95%（202,031.28公顷）下降至2024年的42.07%（110,449.55公顷），减少了50%。受干扰森林从13.48%增至27.80%，农田从6.90%扩展至26.08%。因子分析识别出四类主要森林资源：木材\u002F木炭\u002F纤维（方差贡献率35.4%）、药用植物\u002F根茎\u002F森林土壤（14.8%）、水果\u002F动物饲料（9.9%）以及肉类\u002F蜂蜜（7.0%）。多元回归表明，社会经济因素显著影响家庭对森林的依赖（R² = 0.279，F = 29.779，p \u003C 0.001），其中教育程度、年龄和职业是最强的预测因子。卡方分析证实，社区认为森林资源对社会经济发展具有显著贡献（χ² = 221.718，df = 32，p \u003C 0.001）。研究结论认为，农业扩张和木材采伐是森林退化的主要驱动因素，亟需通过生计多样化干预措施来减少对森林的依赖，同时维持农村福祉。研究建议：实施社区参与式森林保护项目；投资农村教育\u002F扩大职业培训以提供替代收入来源；持续利用遥感进行定期监测，以追踪森林覆盖趋势并为适应性管理提供依据。","Journal of Science Research and Reviews","2026-09-12T00:00:00Z",65,{"impact":17,"substance":394,"depth":395,"authority":346,"freshness":21,"relevant":22,"comment":396},20,16,"基于Landsat长时序遥感与入户调查的尼日利亚森林退化与生计依赖研究，方法扎实、数据翔实，但属区域案例，对国内三农信息化仅有方法借鉴价值。",[398],{"name":390,"url":387},[28,29,30,400,401],"森林资源","农村生计",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[404],{"code":54,"slug":115,"name":116,"path":117,"parent_code":37},{"status":40,"locked":14,"version":41,"method":42,"evidence":406},{"candidates":407,"agricultural_evidence":47},[408,412,416,423,429,435],{"code":33,"score":122,"supported":47,"title":409,"abstract":410,"tags":411},[51],[50,51],[28],{"code":54,"score":346,"supported":47,"title":413,"abstract":414,"tags":415},[30],[30],[30],{"code":417,"score":20,"supported":47,"title":418,"abstract":419,"tags":422},"H2",[],[420,421],"土壤","soil",[],{"code":424,"score":133,"supported":47,"title":425,"abstract":426,"tags":428},"B6",[],[427],"药用植物",[],{"code":430,"score":133,"supported":47,"title":431,"abstract":432,"tags":434},"C4",[],[433],"饲料",[],{"code":65,"score":22,"supported":14,"title":436,"abstract":437,"tags":438},[],[],[29],[440,441],"农村生计 土地利用 森林资源 遥感监测","农村生计 土地利用","农村生计土地利用森林资源遥感监测-2319","10.70882\u002Fjosrar.2026.v3i5.278",{"doi":443,"openalex_id":445,"authors":446,"venue":390,"cited_by_count":88,"oa_url":387,"card":451,"direction":93,"ingested_from":95},"W7212392638",[447,449],{"name":448,"orcid":9},"David E.
