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。",null,"Journal of Landscape Ecology","2026-09-19T00:00:00Z","论文",10,false,0,{"impact":15,"substance":15,"depth":15,"authority":15,"freshness":15,"relevant":15,"comment":17},"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。",[19],{"name":10,"url":6},[21,22,23,24],"耕地保护","遥感监测","土地利用","城市扩张",{"code":26,"slug":27,"name":28,"path":29,"parent_code":30},"I3","remote-sensing","遥感与农情监测","\u002Ftopic\u002Fdigital-agriculture\u002Fremote-sensing","I",[32],{"code":33,"slug":34,"name":35,"path":36,"parent_code":30},"I4","gis","GIS与空间分析","\u002Ftopic\u002Fdigital-agriculture\u002Fgis",{"status":38,"locked":14,"version":39,"method":40,"evidence":41},"classified","2026-10-22.2","rules",{"candidates":42,"agricultural_evidence":45},[43,51,58,65,71],{"code":26,"score":44,"supported":45,"title":46,"abstract":48,"tags":50},15,true,[47],"remote sensing",[49,47],"遥感",[22],{"code":33,"score":52,"supported":45,"title":53,"abstract":55,"tags":57},14,[54],"GIS",[56,54],"地理信息",[],{"code":59,"score":60,"supported":45,"title":61,"abstract":62,"tags":64},"G2",3,[],[63],"land transfer",[],{"code":66,"score":67,"supported":14,"title":68,"abstract":69,"tags":70},"H1",1,[],[],[21],{"code":72,"score":67,"supported":14,"title":73,"abstract":74,"tags":75},"H6",[],[],[23],[77,78],"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",9,"10.2478\u002Fjlecol-2026-0038",{"doi":81,"openalex_id":83,"authors":84,"venue":10,"cited_by_count":15,"oa_url":92,"card":93,"direction":97,"ingested_from":99},"W7213652939",[85,87,89],{"name":86,"orcid":9},"Amina Kalbaza",{"name":88,"orcid":9},"Belkacem Marir",{"name":90,"orcid":91},"Farida Naceur","https:\u002F\u002Forcid.org\u002F0009-0004-1962-4937","https:\u002F\u002Freference-global.com\u002Fdownload\u002Farticle\u002F10.2478\u002Fjlecol-2026-0038.pdf",{"tldr":94,"method":95,"finding":96,"direction":97,"opportunity":98},"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。","农业遥感与作物表型","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。","openalex","2026-09-21T23:30:24.332177Z",{"total":102,"page":67,"page_size":102,"items":103},6,[104,178,244,309,380,440],{"id":105,"title":106,"url":107,"summary":108,"summary_zh":109,"content":9,"source_name":110,"source_url":111,"published_at":112,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":113,"score_detail":114,"sources":119,"tags":121,"primary_topic":125,"secondary_topics":126,"classification":128,"search_phrases":158,"slug":161,"view_count":162,"doi":163,"paper":164,"created_at":177},3187,"Spatio-temporal analysis of Land Use and Land Cover (LULC) change using high resolution satellite data: A case study of Nagaon, Assam","https:\u002F\u002Fdoi.org\u002F10.31018\u002Fjans.v18i3.7774","Geographic information systems (GIS) coupled with satellite remote sensing (RS) have had a significant impact on the assessment and mapping of land surface dynamics, specifically the analysis of land-use land-cover (LULC) change.

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":115,"substance":116,"depth":44,"authority":13,"freshness":80,"relevant":67,"comment":188},"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。",[190],{"name":184,"url":181},[192,22,23,54,193],"城镇化","矿区生态",{"code":26,"slug":27,"name":28,"path":29,"parent_code":30},[196],{"code":33,"slug":34,"name":35,"path":36,"parent_code":30},{"status":38,"locked":14,"version":39,"method":40,"evidence":198},{"candidates":199,"agricultural_evidence":45},[200,204,208,214],{"code":26,"score":44,"supported":45,"title":201,"abstract":202,"tags":203},[47],[49,47],[22],{"code":33,"score":132,"supported":45,"title":205,"abstract":206,"tags":207},[54],[54],[54],{"code":209,"score":60,"supported":45,"title":210,"abstract":211,"tags":213},"I7",[],[212],"研究方法",[],{"code":72,"score":215,"supported":14,"title":216,"abstract":217,"tags":218},2,[],[],[23,193],[220,221],"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":223,"openalex_id":225,"authors":226,"venue":184,"cited_by_count":15,"oa_url":181,"card":238,"direction":97,"ingested_from":99},"W7213550535",[227,229,231,234,236],{"name":228,"orcid":9},"Sogbè KEITA",{"name":230,"orcid":9},"Mamady Minata CONDÉ",{"name":232,"orcid":233},"Ibrahima Thiam","https:\u002F\u002Forcid.org\u002F0000-0001-8553-1043",{"name":235,"orcid":9},"Lucien SOLIE",{"name":237,"orcid":9},"Alpha Issaga Pallé Diallo",{"tldr":239,"method":240,"finding":241,"direction":97,"opportunity":242},"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":245,"title":246,"url":247,"summary":248,"summary_zh":249,"content":9,"source_name":250,"source_url":247,"published_at":251,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":113,"score_detail":252,"sources":254,"tags":256,"primary_topic":260,"secondary_topics":261,"classification":263,"search_phrases":283,"slug":286,"view_count":67,"doi":287,"paper":288,"created_at":308},2323,"Land cover transformations in northern Algeria from 2001 to 2021: A MODIS-based spatiotemporal analysis","https:\u002F\u002Fdoi.org\u002F10.30493\u002Fdas.2026.011109","Land use\u002Fland cover (LULC) changes in northern Algeria from 2001 to 2021 were investigated in this research. The assessment utilized the MODIS MCD12Q1 dataset combined with Geographic Information System (GIS) techniques. Substantial landscape transformations were highlighted by the findings. Forests (+47.52%), shrublands (+17.65%), wetlands (+58.64%), and natural vegetation (+465.72%) experienced notable growth, whereas a drop of −14.13% was documented for barren lands by the end of study period. Moderate overall growth was displayed by agricultural lands, despite various fluctuations throughout the timeline. Concurrently, a continuous expansion (+3.90%) driven by escalating anthropogenic pressure was recorded in urban and built-up areas. Regional landscape evolution is clearly shaped by a combination of factors. Climatic variability, ecological succession, land management practices, and human activities collectively drive these observed dynamics. Partial alignment with previously documented vegetation recovery and urban expansion trends in Algeria was demonstrated by comparative literature reviews. However, the moderate spatial resolution (500 m) of the MODIS MCD12Q1 product likely caused several identified data discrepancies. Ultimately, the immense value of remote sensing and GIS approaches for regional environmental monitoring is proven by this project.

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":115,"substance":319,"depth":320,"authority":132,"freshness":80,"relevant":67,"comment":321},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。",[323],{"name":315,"url":312},[22,23,54,325,326],"森林资源","农村生计",{"code":26,"slug":27,"name":28,"path":29,"parent_code":30},[329],{"code":33,"slug":34,"name":35,"path":36,"parent_code":30},{"status":38,"locked":14,"version":39,"method":40,"evidence":331},{"candidates":332,"agricultural_evidence":45},[333,337,341,345,351,357],{"code":26,"score":44,"supported":45,"title":334,"abstract":335,"tags":336},[47],[49,47],[22],{"code":33,"score":132,"supported":45,"title":338,"abstract":339,"tags":340},[54],[54],[54],{"code":143,"score":102,"supported":45,"title":342,"abstract":343,"tags":344},[],[146,147],[],{"code":346,"score":60,"supported":45,"title":347,"abstract":348,"tags":350},"B6",[],[349],"药用植物",[],{"code":352,"score":60,"supported":45,"title":353,"abstract":354,"tags":356},"C4",[],[355],"饲料",[],{"code":72,"score":67,"supported":14,"title":358,"abstract":359,"tags":360},[],[],[23],[362,363],"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",4,"10.70882\u002Fjosrar.2026.v3i5.278",{"doi":366,"openalex_id":368,"authors":369,"venue":315,"cited_by_count":15,"oa_url":312,"card":374,"direction":97,"ingested_from":99},"W7212392638",[370,372],{"name":371,"orcid":9},"David E.

Chitrakoot district of Uttar Pradesh presents a distinctive case of hydro-climatic vulnerability because it belongs to the drought-prone Bundelkhand region but simultaneously experiences recurrent riverine and flash-flood conditions during intense monsoon rainfall. The present study assesses the spatial characteristics and determinants of flood hazard and vulnerability in Chitrakoot district using an integrated geographical, GIS and remote sensing approach. The analysis incorporates the Digital Elevation Model (DEM), drainage network, physiography, river proximity, historical flood information, satellite-based flood observations and socio-economic exposure. The district's DEM indicates a marked elevation gradient, approximately from 66 m to 451 m, with relatively higher terrain in the southern part and lower terrain towards the northern Yamuna valley. This topographic configuration facilitates rapid surface runoff from elevated southern terrain towards comparatively low-lying riverine areas. The drainage system is dominated by the Yamuna and Mandakini\u002FPaisuni systems along with Baghain, Gunta, Bardaha and smaller tributaries. The Uttar Pradesh Flood Hazard Atlas identifies 5,114 ha of flood-hazard area in Chitrakoot for 1998–2020, of which 4,129 ha (81%) falls in the very-low hazard category and 985 ha (19%) in the low-hazard category. However, the historical classification does not fully represent the potential consequences of extreme rainfall events. The August 2026 flood provides compelling evidence: the Mandakini at Chitrakoot reached a reported new high flood level of 145.60 m on 29 August 2026, approximately 2.95 m above the previous reported high level, while the water level rose by about 7.5 m within six hours. The study concludes that flood risk in Chitrakoot is spatially concentrated around river corridors, low-elevation areas, floodplains, agricultural land, settlements and tourism infrastructure. A shift from conventional relief-oriented flood management towards integrated floodplain regulation, watershed management, GIS-based risk zonation, real-time monitoring and community-based preparedness is therefore essential.","洪水是影响人类住区、农业、基础设施和区域经济的最重要的水文气象灾害之一。北方邦吉德古德（Chitrakoot）县在水文气候脆弱性方面呈现出独特案例，因为它属于易受干旱影响的本德尔坎德（Bundelkhand）地区，但同时在强季风降雨期间反复遭遇河流洪水和山洪状况。本研究采用地理学、地理信息系统（GIS）和遥感相结合的综合方法，评估吉德古德县洪水灾害与脆弱性的空间特征及其决定因素。分析纳入了数字高程模型（DEM）、河网、地貌、距河流远近、历史洪水信息、基于卫星的洪水观测以及社会经济暴露度。该县的DEM显示出明显的高程梯度，大约从66米到451米，南部地形相对较高，向北部的亚穆纳（Yamuna）河谷地势降低。这种地形格局促使地表径流从较高的南部地形快速流向相对低洼的河流区域。排水系统以亚穆纳河和曼达基尼\u002F派苏尼（Mandakini\u002FPaisuni）水系为主，另有巴盖恩（Baghain）、贡塔（Gunta）、巴尔达哈（Bardaha）及较小支流。北方邦洪水灾害图集确认，1998—2020年吉德古德县洪水灾害面积为5，114公顷，其中4，129公顷（81%）属于极低灾害类别，985公顷（19%）属于低灾害类别。然而，历史分类并不能充分反映极端降雨事件的潜在后果。2026年8月的洪水提供了有力证据：据报道，2026年8月29日吉德古德的曼达基尼河达到145.60米的新高洪水位，比此前报告的高水位高出约2.95米，而水位在六小时内上升了约7.5米。研究得出结论，吉德古德的洪水风险在空间上集中于河流廊道、低海拔地区、洪泛平原、农业用地、住区和旅游基础设施周围。因此，必须从传统的以救济为导向的洪水管理转向洪泛平原综合调控、流域管理、基于GIS的风险区划、实时监测和社区为基础的备灾。","International Journal For Multidisciplinary Research","2026-10-17T00:00:00Z",{"impact":15,"substance":15,"depth":15,"authority":15,"freshness":15,"relevant":15,"comment":389},"该研究聚焦印度北方邦的洪水灾害评估，虽涉及GIS与遥感方法，但与三农、农业信息化、智慧农业等主题无直接关联，不建议进入每日精选。",[391],{"name":386,"url":383},[393,22,394,395],"防灾减灾","洪水风险评估","GIS应用",{"code":26,"slug":27,"name":28,"path":29,"parent_code":30},[398,399],{"code":33,"slug":34,"name":35,"path":36,"parent_code":30},{"code":400,"slug":401,"name":402,"path":403,"parent_code":404},"H7","climate","气候适应与防灾减灾","\u002Ftopic\u002Fenvironment\u002Fclimate","H",{"status":38,"locked":14,"version":39,"method":40,"evidence":406},{"candidates":407,"agricultural_evidence":45},[408,412,416],{"code":26,"score":44,"supported":45,"title":409,"abstract":410,"tags":411},[47],[49,47],[22],{"code":33,"score":52,"supported":45,"title":413,"abstract":414,"tags":415},[54],[56,54],[],{"code":400,"score":115,"supported":45,"title":417,"abstract":418,"tags":421},[],[419,420],"干旱","drought",[394,393],[423,424],"Chitrakoot 洪水风险 GIS","Yamuna 洪水脆弱性 遥感","Chitrakoot洪水风险GIS-5326","10.36948\u002Fijfmr.2026.v08i05.89708",{"doi":426,"openalex_id":428,"authors":429,"venue":386,"cited_by_count":15,"oa_url":433,"card":434,"direction":97,"ingested_from":99},"W7222885988",[430],{"name":431,"orcid":432},"Birendra Yadav","https:\u002F\u002Forcid.org\u002F0009-0007-0864-474X","https:\u002F\u002Fwww.ijfmr.com\u002Fpapers\u002F2026\u002F5\u002F89708.pdf",{"tldr":435,"method":436,"finding":437,"direction":97,"opportunity":438},"用GIS与遥感综合评估Chitrakoot区洪水灾害与脆弱性空间分布。","DEM、河网、历史洪水与卫星观测及社会经济数据叠加分析。","洪水风险集中于河谷低地、农田与居民点，历史分级低估极端降雨风险。","可结合时序遥感与水文模型，构建极端降雨情景下的农田洪涝风险动态制图与预警。","2026-10-19T23:30:24.356743Z",{"id":441,"title":442,"url":443,"summary":444,"summary_zh":445,"content":9,"source_name":446,"source_url":443,"published_at":447,"category":12,"cover_url":9,"hotness":448,"is_selected":14,"score":317,"score_detail":449,"sources":451,"tags":455,"primary_topic":458,"secondary_topics":459,"classification":461,"search_phrases":476,"slug":479,"view_count":67,"doi":480,"paper":481,"created_at":497},3895,"Analysis Of Changes In Land Use And Land Cover In Pune City Over A Decade Using Geospatial Techniques.","https:\u002F\u002Fdoi.org\u002F10.5281\u002Fzenodo.23053479","Abstract Land use and land cover (LULC) changes play a significant role in reflecting natural and anthropogenic environmental changes. In this study, changes in 'Land Use and Land Cover' (LULC) in Pune city for the period 2015-2025 have been analysed using the techniques of 'Remote Sensing' and 'Geographic Information System' (GIS). The May 2015 and May 2025 30 m resolution Landsat 08 satellite images were used. For LULC classification, the 'Supervised Maximum Likelihood Classification' method was used, resulting in 5 major LULC classes: built-up land, barren land, and agricultural land, vegetation, and water bodies. More than 100 'training samples' were taken for each land cover type to improve classification accuracy. The findings of the study show that there was a considerable shift in the spatial distribution of LULC in this decade. Built-up land increased from 154.48 sq. km (30.48%) in 2015 to 292.26 sq. km (57.86%) in 2025, representing an increase of approximately 137.78 sq. km. Conversely, the area of barren land decreased from 203.94 sq. km (40.24%) to 106.93 sq. km (21.10%). The amount of agricultural land has reduced from 44.39 sq. km (8.75%) to 18.93 sq. km (3.72%), indicating that agricultural land has been converted for urbanisation on a large scale. Regarding vegetation cover, 85.91 sq. km showed a marginal decrease from 16.95% to 15.58%, whereas the area of water bodies decreased from 18.13 sq. km (3.58%) to 10.77 sq. km (2.12%). The results show the rapid growth of Pune city during the study period, which is mainly observed in the loss or transformation of barren land, agricultural land and water bodies. The study shows the usefulness of using Landsat data, ‘supervised maximum likelihood classification’, GIS and ‘change detection' techniques for tracking long-term urban growth and environmental changes. The results of this research can help urban planners and decision makers in formulating policies for sustainable land use and in safeguarding environmentally sensitive areas.","摘要 土地利用与土地覆盖（LULC）变化在反映自然与人为环境变化方面发挥着重要作用。本研究利用遥感（Remote Sensing）和地理信息系统（GIS）技术，分析了浦那市2015—2025年期间土地利用与土地覆盖（LULC）的变化。研究使用了2015年5月和2025年5月分辨率为30米的Landsat 08卫星影像。在LULC分类中，采用了监督最大似然分类（Supervised Maximum Likelihood Classification）方法，最终得到5个主要LULC类别：建设用地、裸地、农用地、植被和水体。为提高分类精度，每种土地覆盖类型均选取了100个以上的训练样本（training samples）。研究结果表明，在这十年间，LULC的空间分布发生了显著变化。建设用地从2015年的154.48平方公里（30.48%）增加到2025年的292.26平方公里（57.86%），增加了约137.78平方公里。相反，裸地面积从203.94平方公里（40.24%）减少到106.93平方公里（21.10%）。农用地面积从44.39平方公里（8.75%）减少到18.93平方公里（3.72%），表明农用地已大规模转化为城市化用地。植被覆盖方面，85.91平方公里略有下降，从16.95%降至15.58%；水体面积则从18.13平方公里（3.58%）减少到10.77平方公里（2.12%）。结果表明，研究期间浦那市快速扩张，主要体现在裸地、农用地和水体的减少或转变上。研究表明，利用Landsat数据、监督最大似然分类、GIS和变化检测（change detection）技术对于追踪长期城市增长与环境变化具有重要价值。本研究结果可帮助城市规划者和决策者制定可持续土地利用政策，并保护环境敏感区域。","Zenodo (CERN European Organization for Nuclear Research)","2026-09-30T00:00:00Z",25,{"impact":115,"substance":319,"depth":320,"authority":132,"freshness":80,"relevant":67,"comment":450},"基于Landsat遥感与GIS的浦那市十年土地利用变化研究，数据翔实、结论明确，对农业用地流失与城市扩张监测有参考价值，但属区域案例研究，公共影响有限。",[452,453],{"name":446,"url":443},{"name":446,"url":454},"https:\u002F\u002Fdoi.org\u002F10.5281\u002Fzenodo.23053480",[49,23,456,54,457],"Landsat","城市化",{"code":33,"slug":34,"name":35,"path":36,"parent_code":30},[460],{"code":26,"slug":27,"name":28,"path":29,"parent_code":30},{"status":38,"locked":14,"version":39,"method":40,"evidence":462},{"candidates":463,"agricultural_evidence":45},[464,468,472],{"code":33,"score":13,"supported":45,"title":465,"abstract":466,"tags":467},[],[56,54,140],[54],{"code":26,"score":115,"supported":45,"title":469,"abstract":470,"tags":471},[],[49,47],[456,49],{"code":72,"score":67,"supported":14,"title":473,"abstract":474,"tags":475},[],[],[23],[477,478],"土地利用 城市化 遥感 Landsat","土地利用 城市化","土地利用城市化遥感Landsat-3895","10.5281\u002Fzenodo.23053479",{"doi":480,"openalex_id":482,"authors":483,"venue":446,"cited_by_count":15,"oa_url":443,"card":492,"direction":97,"ingested_from":99},"W7214889813",[484,486,488,490],{"name":485,"orcid":9},"Kalyani Machhindra sonawane",{"name":487,"orcid":9},"Sumitra Nandkumar Nikam",{"name":489,"orcid":9},"Sunil W.
