These trends have important implications for environmental quality, urban sustainability, and climate resilience. This paper investigates the spatial relationship between urban sprawl and traffic-related air pollution (TRAP) in Greater Gaborone, Botswana, using Geographic Information Systems (GIS) and remote sensing techniques. Landsat imagery from the United States Geological Survey (USGS), accessed via Google Earth Engine, is used to map land use and land cover change between 2006 and 2026, and Sentinel-5P TROPOMI tropospheric NO2 data are used to map TRAP hotspots for 2026 using the Getis-Ord Gi* statistic. Built-up land area in Greater Gaborone grew by 79.6% over the study period, spreading outward from the historic core in multiple directions. TRAP hotspots are concentrated in this core and extend along the city's major roads into nearby growth areas, while more distant peripheral growth remains in the coldspot zone. This suggests that pollution has not spread uniformly with the built-up footprint, and that Greater Gaborone's transport corridors may play a role in shaping which growth areas experience elevated pollution and which do not. These findings offer evidence-based insights for land use planning and air quality management within Botswana's urban development framework, and highlight that Greater Gaborone spans multiple local government jurisdictions with no single authority responsible for the metropolitan area as a whole.","许多撒哈拉以南非洲城市的快速城市蔓延显著重塑了城市出行模式，导致通勤距离延长、私人车辆依赖加剧以及对主要交通走廊的压力不断增大。这些趋势对环境质量、城市可持续性和气候韧性具有重要影响。本文利用地理信息系统（GIS）和遥感技术，研究了博茨瓦纳大哈博罗内地区城市蔓延与交通相关空气污染（TRAP）之间的空间关系。研究使用通过Google Earth Engine获取的美国地质调查局（USGS）Landsat影像，绘制了2006年至2026年间的土地利用与土地覆盖变化，并利用Sentinel-5P TROPOMI对流层NO2数据，采用Getis-Ord Gi*统计量绘制了2026年TRAP热点分布。研究期间，大哈博罗内的建成区面积增长了79.6%，从历史核心区向多个方向向外扩展。TRAP热点集中在该核心区，并沿城市主要道路延伸至邻近的增长区域，而更远的外围增长区仍处于冷点区。这表明污染并未随建成区足迹均匀扩散，大哈博罗内的交通走廊可能在决定哪些增长区出现污染升高、哪些不升高方面发挥了作用。这些发现为博茨瓦纳城市发展框架内的土地利用规划和空气质量管理提供了基于证据的见解，并凸显出大哈博罗内跨越多个地方政府辖区，没有任何单一机构对整个大都市区负责。",null,"OpenAlex","2026-09-23T00:00:00Z","论文",10,false,0,{"impact":15,"substance":15,"depth":15,"authority":15,"freshness":15,"relevant":15,"comment":17},"研究博茨瓦纳哈博罗内城市扩张与交通空气污染，属城市环境与遥感领域，与三农、农业信息化、智慧农业无关，不建议进入每日精选。",[19],{"name":10,"url":6},[21,22,23,24],"遥感监测","土地利用","城市扩张","交通空气污染",[26,27],"Greater Gaborone 城市扩张","Sentinel-5P NO2 遥感","GreaterGaborone城市扩张-3506","10.31223\u002Fx5v22m",{"doi":29,"openalex_id":31,"authors":32,"venue":9,"cited_by_count":15,"oa_url":40,"card":41,"direction":45,"ingested_from":47},"W7214110791",[33,36,38],{"name":34,"orcid":35},"Keone Kelobonye","https:\u002F\u002Forcid.org\u002F0000-0002-6652-6262",{"name":37,"orcid":9},"Chenesani Sithole",{"name":39,"orcid":9},"Orateng Amos","https:\u002F\u002Feartharxiv.org\u002Frepository\u002Fobject\u002F15173\u002Fdownload\u002F26308\u002F",{"tldr":42,"method":43,"finding":44,"direction":45,"opportunity":46},"用GIS与遥感分析大哈博罗内城市蔓延与交通相关空气污染的空间关系。","Landsat与Sentinel-5P NO2数据，结合Getis-Ord Gi","建设用地增79.6%，污染热点集中于核心区并沿主干道延伸，外围增长区仍为冷点。","农业遥感与作物表型","可延伸至城乡交错带交通污染暴露与土地利用协同治理，关注跨辖区空气质量管理机制。","openalex","2026-09-25T23:30:33.701778Z",{"total":50,"page":51,"page_size":50,"items":52},6,1,[53,89,118,157,199,227],{"id":54,"title":55,"url":56,"summary":57,"summary_zh":58,"content":9,"source_name":59,"source_url":56,"published_at":60,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":15,"score_detail":61,"sources":63,"tags":65,"search_phrases":67,"slug":70,"view_count":15,"doi":71,"paper":72,"created_at":88},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":15,"substance":15,"depth":15,"authority":15,"freshness":15,"relevant":15,"comment":62},"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。",[64],{"name":59,"url":56},[66,21,22,23],"耕地保护",[68,69],"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":71,"openalex_id":73,"authors":74,"venue":59,"cited_by_count":15,"oa_url":82,"card":83,"direction":45,"ingested_from":47},"W7213652939",[75,77,79],{"name":76,"orcid":9},"Amina Kalbaza",{"name":78,"orcid":9},"Belkacem Marir",{"name":80,"orcid":81},"Farida Naceur","https:\u002F\u002Forcid.org\u002F0009-0004-1962-4937","https:\u002F\u002Freference-global.com\u002Fdownload\u002Farticle\u002F10.2478\u002Fjlecol-2026-0038.pdf",{"tldr":84,"method":85,"finding":86,"direction":45,"opportunity":87},"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":90,"title":91,"url":92,"summary":93,"summary_zh":94,"content":9,"source_name":59,"source_url":92,"published_at":60,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":15,"score_detail":95,"sources":97,"tags":99,"search_phrases":101,"slug":104,"view_count":15,"doi":105,"paper":106,"created_at":117},3015,"Forecasting Urbanization Dynamics On İstanbul’s European Side Using Deep Learning And Extrapolation Techniques","https:\u002F\u002Fdoi.org\u002F10.2478\u002Fjlecol-2026-0037","Abstract Rapid urbanization in metropolitan regions poses significant environmental, social, and infrastructural challenges, necessitating advanced analytical approaches to monitor and predict urban growth.

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 results show that Zaria Urban Area currently hosts 23 tertiary institutions. Institutional land acquisition increased to 10,825.22 hectares over the study period, representing significant spatial expansion, with only about 32.88% of the acquired land having been developed into built‑up areas. However, residential and circulation accounted for the largest proportions of campus development with 29.26% and 29.53%, respectively, demonstrating that tertiary institutions function as growth poles that influence urban spatial development and land transformation within Zaria. Based on these facts, the study recommended that KADSUPDA should develop institutional land‑use planning frameworks, strengthening collaboration between KADSUPDA and tertiary institutions, promoting sustainable campus development strategies, and integrating institutional expansion into urban master planning.","高等教育机构日益被视为城市土地转型与空间发展的重要驱动力。本研究考察了尼日利亚卡杜纳州扎里亚城市区（ZUA）高等教育机构相关的土地利用与土地覆盖（LULC）动态。研究运用地理信息系统（GIS）和遥感技术，分析了覆盖1924年至2024年的多时相空间数据，以考察机构土地获取与建成区开发情况。结果表明，扎里亚城市区目前拥有23所高等教育机构。在研究期内，机构土地获取面积增至10,825.22公顷，呈现出显著的空间扩张，但其中仅有约32.88%的已获取土地被开发为建成区。然而，住宅和交通用地在校园开发中占比最大，分别为29.26%和29.53%，表明高等教育机构作为增长极，影响着扎里亚的城市空间发展和土地转型。基于上述事实，研究建议卡杜纳州城市规划和开发局（KADSUPDA）制定机构土地利用规划框架，加强KADSUPDA与高等教育机构之间的合作，推广可持续校园发展策略，并将机构扩张纳入城市总体规划。","IIARD INTERNATIONAL JOURNAL OF GEOGRAPHY AND ENVIRONMENTAL MANAGEMENT","2026-09-10T00:00:00Z",{"impact":15,"substance":15,"depth":15,"authority":15,"freshness":15,"relevant":15,"comment":208},"研究尼日利亚扎里亚高校驱动的土地利用变化，属城市地理与遥感领域，与三农、农业信息化、智慧农业无关，不建议进入每日精选。",[210],{"name":205,"url":202},[21,22,23],[131,132],"土地利用城市扩张遥感监测-2327","10.56201\u002Fijgem.vol.12.no3.2026.pg71.82",{"doi":214,"openalex_id":216,"authors":217,"venue":205,"cited_by_count":15,"oa_url":220,"card":221,"direction":45,"ingested_from":47},"W7212149575",[218],{"name":219,"orcid":9},"Baba E.

This study examines urban transformation between 1985 and 2025 using an integrated socio-spatial framework combining remote sensing and socio-economic datasets. It analyses built-up expansion, land valuation, population change, spatial accessibility, and tourism trends to understand long-term metropolitan restructuring. The results show a substantial increase in built-up area from 7930 ha in 1985 to 19,956 ha in 2025, accompanied by a continuous decline in non built-up land. Urban growth has evolved from a predominantly compact core toward a more dispersed and corridor-oriented spatial pattern, with expansion occurring in association with transport connectivity, accessibility gradients, and peripheral land-use change. Land values represented by official circle rates across residential, commercial, and agricultural categories increased substantially between 2013 and 2026, indicating rising land valuation and spatial differentiation in development pressure. Population increased from 126,344 in 1911 to 1,219,516 in 2011 and is projected to reach 1,795,174 by 2031, while the level of urbanisation increased from 61.76% to 99.45%. Tourist arrivals increased from 10,580 in 1951 to 2,986,780 in 2024, demonstrating the growing significance of tourism within the regional economy. The findings indicate that Srinagar's urban transformation reflects the interaction of spatial expansion, accessibility, land-market dynamics, demographic change, and tourism rather than population growth alone. The study highlights the need for integrated and regulated urban planning approaches to manage metropolitan expansion in the environmentally sensitive Himalayan region and provides a transferable framework for analysing long term urban dynamics and supporting sustainable urban management in mountain cities.","斯利那加是印度喜马拉雅地区最大的大都市中心之一，人口超过一百万。本研究采用遥感与社会经济数据集相结合的综合社会—空间框架，考察1985年至2025年间的城市转型。研究分析了建成区扩张、土地估值、人口变化、空间可达性和旅游趋势，以理解长期的大都市重构过程。结果表明，建成区面积从1985年的7930公顷大幅增加至2025年的19956公顷，同时非建成区土地持续减少。城市增长已从以紧凑核心区为主，演变为更加分散且沿走廊导向的空间格局，其扩张与交通连通性、可达性梯度及边缘土地利用变化相关联。2013年至2026年间，住宅、商业和农业类别的官方基准地价所反映的土地价值大幅上升，表明土地估值上升及发展压力的空间分异。人口从1911年的126344人增加至2011年的1219516人，预计到2031年将达到1795174人，而城市化水平从61.76%上升至99.45%。游客到访量从1951年的10580人次增加至2024年的2986780人次，表明旅游业在区域经济中的重要性日益增强。研究结果表明，斯利那加的城市转型反映的是空间扩张、可达性、土地市场动态、人口变化和旅游业之间的相互作用，而非仅由人口增长所致。本研究强调，需要在环境敏感的喜马拉雅地区采取综合且受监管的城市规划方法来管理大都市扩张，并为分析长期城市动态及支持山地城市可持续城市管理提供了一个可迁移的框架。","City and Environment Interactions","2026-09-07T00:00:00Z",{"impact":15,"substance":15,"depth":15,"authority":15,"freshness":15,"relevant":15,"comment":236},"研究印度斯利那加城市空间演变，属城市地理与规划领域，与三农、农业信息化、数字乡村无直接关联，不建议进入每日精选。",[238],{"name":233,"url":230},[21,22,23,240,241],"人口变化","山地城市",[243,244],"人口变化 土地利用 城市扩张 山地城市","人口变化 土地利用","人口变化土地利用城市扩张山地城市-2067","10.1016\u002Fj.cacint.2026.100464",{"doi":246,"openalex_id":248,"authors":249,"venue":233,"cited_by_count":15,"oa_url":253,"card":254,"direction":45,"ingested_from":47},"W7211881163",[250],{"name":251,"orcid":252},"Altaf Hussain","https:\u002F\u002Forcid.org\u002F0000-0002-7960-5621","https:\u002F\u002Fwww.sciencedirect.com\u002Fscience\u002Farticle\u002Fpii\u002FS2590252026001716\u002Fpdf",{"tldr":255,"method":256,"finding":257,"direction":258,"opportunity":259},"基于遥感与社会经济数据，分析斯利那加1985-2025年城市扩张、地价、人口与旅游动态。","遥感与社会经济数据集，结合建成区、地价、可达性、人口和旅游趋势分析。","建成区从7930公顷增至19956公顷，城市由紧凑核心转向分散走廊式扩张，地价与旅游显著增长。","数字乡村与农业信息化","可借鉴其多源数据融合框架，研究山区城市扩张对农业用地与乡村生计的耦合影响。","2026-09-10T23:30:31.626380Z"]
