A highly significant spatial and ecological differentiation of phenotypes was revealed along a gradient of vegetation condition. Green individuals tend to occur in mesic habitats with relatively dense vegetation, whereas gray individuals are associated with areas characterized by sparse or senescent vegetation. The within-season trend in the relative proportions of the color forms is nonlinear: the proportion of green adults consistently increases toward mid-summer, reaching a maximum in late July to the first half of August. This trend is distorted in years characterized by large-scale macroclimatic anomalies. The population-level patterns identified are consistent with the life form of Oe. decorus as a subcover geophile.","基于公民科学数据（iNaturalist、GBIF）与卫星遥感数据（NASA MODIS）的整合，我们研究了古北区英俊小车蝗Oedaleus decorus（Germar, 1825）体色多态性的宏观生态格局。研究揭示了表型沿植被状况梯度存在极显著的空间与生态分化。绿色个体倾向于出现在植被相对茂密的湿润生境中，而灰色个体则与植被稀疏或衰老的区域相关联。体色型相对比例的季节内变化趋势呈非线性：绿色成虫的比例持续向仲夏增加，在7月下旬至8月上半月达到最大值。在大尺度宏观气候异常年份，这一趋势会发生扭曲。所识别的种群水平格局与Oe. decorus作为亚覆盖层土栖种的生活型相一致。",null,"Ecologica Montenegrina","2026-09-28T00:00:00Z","论文",10,false,67,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},8,20,17,13,9,1,"公民科学数据与卫星遥感结合的宏观生态学研究，方法新颖、结论可靠，但属基础生态学范畴，与农业信息化仅间接相关，公共价值有限。",[25],{"name":10,"url":6},[27,28,29,30,31],"生物多样性","遥感监测","草原生态","植被指数","公民科学",[],{"status":34,"locked":14,"version":35,"method":36,"evidence":37},"needs_review","2026-10-22.2","rules",{"candidates":38,"agricultural_evidence":14,"reason":53},[39,47],{"code":40,"score":17,"supported":41,"title":42,"abstract":43,"tags":46},"I3",true,[],[44,45],"遥感","remote sensing",[30,28],{"code":48,"score":49,"supported":14,"title":50,"abstract":51,"tags":52},"H6",2,[],[],[27,29],"农业相关性需要复核",[55,56],"Oedaleus decorus 体色多态性","iNaturalist MODIS 蝗虫","Oedaleusdecorus体色多态性-3834",5,"10.37828\u002Fem.2026.102.6",{"doi":59,"openalex_id":61,"authors":62,"venue":10,"cited_by_count":66,"oa_url":67,"card":68,"direction":72,"ingested_from":74},"W7214620148",[63],{"name":64,"orcid":65},"Pavel V.

Understanding these distinct vulnerabilities is essential for developing effective policies to mitigate climate change impacts and ensuring sustainable environmental management. This study examines agro-climatic vulnerabilities in Nottinghamshire County (United Kingdom) and Udaipur District (India) from 2000 to 2024, comparing climate change impacts across temperate and semi-arid agricultural systems that represent fundamentally different system behaviours under contrasting climatic conditions. Using multi-temporal Landsat imagery and WorldClim climate data, nine environmental indices were analysed: the Normalized Difference Vegetation Index (NDVI), Vegetation Condition Index (VCI), Normalized Difference Water Index (NDWI), Moisture Stress Index (MSI), Land Surface Temperature (LST), Temperature Condition Index (TCI), Vegetation Health Index (VHI), Drought Risk Index (DRI), and Crop Health Index (CHI). The results reveal contrasting regional trajectories that challenge conventional assumptions about climate vulnerability. Udaipur exhibited improved vegetation and moisture conditions across the observation period, whereas Nottinghamshire showed intensifying moisture stress and declining precipitation. Warming was more pronounced in Nottinghamshire, while strong inter-index correlations validated the monitoring approach. These findings indicate that Udaipur benefits from intensified monsoon patterns, requiring flood mitigation and water-storage infrastructure, whereas Nottinghamshire’s rising moisture stress underscores the need for sustained monitoring and adaptive management. This comparative framework provides evidence-based insights for region-specific adaptation strategies essential to sustainable agricultural development across diverse agro-climatic zones.","不同气候区域表现出独特的农业气候脆弱性，而这些脆弱性在很大程度上受到气候胁迫的影响。理解这些不同的脆弱性对于制定有效政策以减缓气候变化影响、确保可持续环境管理至关重要。本研究考察了2000年至2024年间英国诺丁汉郡与印度乌代布尔县的农业气候脆弱性，比较了温带与半干旱农业系统在气候变化影响下的差异，这两类系统在截然不同的气候条件下代表了根本不同的系统行为。研究利用多时相Landsat影像和WorldClim气候数据，分析了九个环境指数：归一化植被指数（NDVI）、植被状态指数（VCI）、归一化水体指数（NDWI）、水分胁迫指数（MSI）、地表温度（LST）、温度状态指数（TCI）、植被健康指数（VHI）、干旱风险指数（DRI）和作物健康指数（CHI）。结果揭示了截然不同的区域变化轨迹，挑战了关于气候脆弱性的传统假设。乌代布尔在观测期内表现出植被和水分条件的改善，而诺丁汉郡则显示出加剧的水分胁迫和降水减少。诺丁汉郡的增温更为显著，而指数间较强的相关性验证了该监测方法。这些发现表明，乌代布尔受益于季风模式的增强，需要防洪和水储存基础设施，而诺丁汉郡不断上升的水分胁迫则凸显了持续监测和适应性管理的必要性。这一比较框架为因地制宜的适应策略提供了循证依据，对跨不同农业气候区的可持续发展至关重要。","Remote Sensing","2026-10-12T00:00:00Z",75,{"impact":89,"substance":90,"depth":91,"authority":92,"freshness":21,"relevant":22,"comment":93},12,22,18,14,"基于多时相遥感与九项环境指数的跨区域对比研究，方法扎实、结论具政策参考价值，但属学术论文，产业影响有限。",[95],{"name":85,"url":82},[28,30,97,98,99],"干旱风险","适应策略","农业气候",{"code":40,"slug":101,"name":102,"path":103,"parent_code":104},"remote-sensing","遥感与农情监测","\u002Ftopic\u002Fdigital-agriculture\u002Fremote-sensing","I",[106],{"code":107,"slug":108,"name":109,"path":110,"parent_code":111},"H7","climate","气候适应与防灾减灾","\u002Ftopic\u002Fenvironment\u002Fclimate","H",{"status":113,"locked":14,"version":35,"method":36,"evidence":114},"classified",{"candidates":115,"agricultural_evidence":41},[116,120],{"code":40,"score":13,"supported":41,"title":117,"abstract":118,"tags":119},[45],[],[30,28],{"code":107,"score":21,"supported":41,"title":121,"abstract":122,"tags":127},[],[123,124,125,126],"气候变化","干旱","climate change","drought",[],[129,130],"Landsat 遥感 农业气候","诺丁汉郡 乌代布尔","Landsat遥感农业气候-4826","10.3390\u002Frs18203496",{"doi":132,"openalex_id":134,"authors":135,"venue":85,"cited_by_count":66,"oa_url":82,"card":151,"direction":72,"ingested_from":74},"W7221570035",[136,139,142,145,148],{"name":137,"orcid":138},"Bhanwar Vishvendra Raj Singh","https:\u002F\u002Forcid.org\u002F0000-0001-7750-5240",{"name":140,"orcid":141},"Vivek Agarwal","https:\u002F\u002Forcid.org\u002F0000-0003-1185-3802",{"name":143,"orcid":144},"Stuart Marsh","https:\u002F\u002Forcid.org\u002F0000-0002-1168-6760",{"name":146,"orcid":147},"Gajendra Singh Sisodiya","https:\u002F\u002Forcid.org\u002F0009-0006-4118-7491",{"name":149,"orcid":150},"Ajay Sharma","https:\u002F\u002Forcid.org\u002F0009-0001-6077-9875",{"tldr":152,"method":153,"finding":154,"direction":72,"opportunity":155},"用多时相遥感和九项指数对比英国诺丁汉郡与印度乌代浦2000—2024年农业气候脆弱性。","Landsat多时相影像与WorldClim气候数据，计算NDVI、VCI、ND","乌代浦植被与水分条件改善、季风增强，诺丁汉郡水分胁迫加剧、降水下降且升温更明显。","可拓展多区域长时序遥感指数耦合机器学习，构建跨气候带农业气候脆弱性预警与适应决策模型。","2026-10-13T23:30:24.062929Z",{"id":158,"title":159,"url":160,"summary":161,"summary_zh":162,"content":9,"source_name":163,"source_url":160,"published_at":86,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":164,"score_detail":165,"sources":167,"tags":169,"primary_topic":9,"secondary_topics":173,"classification":174,"search_phrases":192,"slug":195,"view_count":66,"doi":196,"paper":197,"created_at":215},4823,"Comparing Sentinel-2 Spectral Indices for Mapping Forest Fire Damage in Pollino National Park, Italy","https:\u002F\u002Fdoi.org\u002F10.5194\u002Fisprs-archives-xlviii-m-13-2026-1-2026","In recent years, climate change has significantly increased the severity and frequency of wildfires across Europe, with the 2025 season marking an unprecedented peak of one million hectares burned.

The analyzed indices include the Normalized Burn Ratio (NBR), Normalized Burn Ratio Plus (NBR+), Normalized Burn Ratio Short Wave Infrared (NBR-SWIR), and Normalized Difference Short Wave Infrared (ND-SWIR). An image differencing technique was applied to pre-fire (June 7, 2025) and post-fire (November 14, 2025) datasets, followed by a supervised Maximum Likelihood classification to map burned and unburned classes. Accuracy assessment via confusion matrices showed that NBR and NBR+ delivered the highest performance, achieving an Overall Accuracy (OA) of 0.976 and 0.974, respectively. ND-SWIR performed closely at 0.966, whereas NBR-SWIR yielded a lower OA of 0.873 due to the misclassification of bare soil transitions as burned areas.

This is a particular challenge in the Brazilian Cerrado, the world's most biodiverse savanna biome and a region experiencing a rapid expansion of agriculture. To inform habitat conservation and restoration actions, we used the Red List of Ecosystems (RLE) framework to identify threatened ecosystems within the Cerrado. This biome is divided into 20 ecoregions, and we subdivided each ecoregion into forest, savanna, grassland, and wetland ecosystems. We used remote sensing data from 1985 to 2020 to measure and predict the distribution of each ecosystem and assess its risk of collapse based on Criterion A2b (reduction in geographic distribution over any 50‐year period), Criterion B1 (limited extent of occurrence), and Criterion B2 (limited area of occupancy). Of the 80 ecosystems comprising the Cerrado, we assessed 12 as Endangered and 43 as Vulnerable. Most of these threatened ecosystems were identified under Criterion A2b, while Criterion B identified a smaller subset of spatially restricted ecosystems, particularly wetlands, underscoring the importance of applying more than one criterion in the assessment process. By using the Red List of Ecosystems as an international standard, we provide the first globally comparable analysis of the state of the Cerrado, showing that nearly three‐quarters of the region's ecosystems are at risk of collapse.

This study investigates the spatial and temporal patterns of agricultural drought over 30 years (1993–2024) by combining meteorological station data with satellite‐derived vegetation and thermal indices. To assess meteorological drought, the standardized precipitation index (SPI) was calculated at 3‐, 6‐, and 12‐month intervals. For agricultural and thermal stress analysis, remote sensing‐based indices including the vegetation condition index (VCI), temperature condition index, and vegetation health index (VHI) were utilized. The results indicate that the years 2003, 2008, and 2018 experienced the most severe droughts, as shown consistently across all indices. Spatial analysis revealed that the central, southern, and eastern lowland areas faced the highest frequency and severity of drought, while the northwestern highlands remained comparatively resilient. Cross‐index correlation revealed strong agreement between SPI and VCI ( R 2 = 0.77), and between VHI and VCI ( R 2 = 0.83), supporting the effectiveness of integrated drought monitoring approaches. This research advances the field of drought assessment by enhancing spatial and temporal resolution and validating cross‐index relationships at the subregional level. The results provide critical insights for localized drought early warning systems, climate adaptation strategies, and future research to improve agricultural resilience under changing climatic conditions. Hence, agricultural drought risk mapping serves as a valuable tool for guiding decision‐making in drought monitoring and for mitigating its impacts on agricultural productivity.","摘要 农业干旱严重威胁粮食安全、生计和生态系统稳定性，尤其是在东巴莱区等易旱地区。本研究结合气象站数据与卫星反演的植被和热力指数，探讨了30年（1993—2024年）间农业干旱的时空格局。为评估气象干旱，计算了3个月、6个月和12个月尺度的标准化降水指数（SPI）。在农业与热胁迫分析方面，采用了基于遥感的植被状态指数（VCI）、温度状态指数和植被健康指数（VHI）。结果表明，2003年、2008年和2018年经历了最严重的干旱，各指数均一致反映了这一情况。空间分析显示，中部、南部和东部低地地区干旱发生频率最高、程度最严重，而西北部高地则相对具有较强恢复力。跨指数相关性分析表明，SPI与VCI之间（R²=0.77）以及VHI与VCI之间（R²=0.83）具有高度一致性，支持了综合干旱监测方法的有效性。本研究通过提高时空分辨率并在次区域尺度上验证跨指数关系，推进了干旱评估领域的发展。研究结果为地方性干旱预警系统、气候适应策略以及未来研究提供了重要见解，有助于在气候变化条件下提升农业韧性。因此，农业干旱风险制图为干旱监测决策及其对农业生产影响的减缓提供了有价值的工具。","Agrosystems Geosciences & Environment","2026-10-11T00:00:00Z",68,{"impact":17,"substance":280,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":281},21,"基于30年气象与遥感指数交叉验证的农业干旱时空制图研究，方法扎实、结论可靠，但属区域性案例，对国内三农信息化仅有方法借鉴价值。",[283],{"name":276,"url":273},[285,286,28,30,287],"粮食安全","防灾减灾","农业干旱",{"code":107,"slug":108,"name":109,"path":110,"parent_code":111},[290],{"code":40,"slug":101,"name":102,"path":103,"parent_code":104},{"status":113,"locked":14,"version":35,"method":36,"evidence":292},{"candidates":293,"agricultural_evidence":41},[294,299,303,309],{"code":107,"score":91,"supported":41,"title":295,"abstract":296,"tags":298},[126],[123,297,124,126],"气候适应",[286],{"code":40,"score":17,"supported":41,"title":300,"abstract":301,"tags":302},[],[44,45],[30,28],{"code":304,"score":246,"supported":41,"title":305,"abstract":306,"tags":308},"A8",[],[285,307],"food security",[285],{"code":310,"score":77,"supported":41,"title":311,"abstract":312,"tags":315},"I4",[],[313,314],"空间分析","spatial analysis",[],[317,318],"埃塞俄比亚 East Bale 农业干旱","SPI VCI 干旱监测","埃塞俄比亚EastBale农业干旱-4747","10.1002\u002Fagg2.70475",{"doi":320,"openalex_id":322,"authors":323,"venue":276,"cited_by_count":66,"oa_url":273,"card":329,"direction":72,"ingested_from":74},"W7221455809",[324,326],{"name":325,"orcid":9},"Murad Hedo Haji",{"name":327,"orcid":328},"Karuturi Venkata Suryabhagavan","https:\u002F\u002Forcid.org\u002F0000-0003-2528-9106",{"tldr":330,"method":331,"finding":332,"direction":72,"opportunity":333},"结合气象站与卫星植被热指数，绘制埃塞俄比亚East Bale区30年农业干旱时空图。","用SPI（3\u002F6\u002F12月）与遥感VCI、TCI、VHI指数做交叉相关分析。","2003、2008、2018年干旱最重，中南部和东部低地最脆弱，SPI与VCI相关性R²=0.77。","可在小区域尺度融合多源指数构建干旱预警模型，并验证指数在不同作物区的适用性。","2026-10-12T23:30:24.342375Z",{"id":336,"title":337,"url":338,"summary":339,"summary_zh":340,"content":9,"source_name":341,"source_url":338,"published_at":277,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":87,"score_detail":342,"sources":344,"tags":346,"primary_topic":350,"secondary_topics":351,"classification":352,"search_phrases":363,"slug":366,"view_count":22,"doi":367,"paper":368,"created_at":383},4738,"Natural ecosystem loss in an Atlantic Forest agricultural basin: drivers of land-use change and future landscape trajectories","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1912707","The Atlantic Forest, one of the world's most threatened biodiversity hotspots, faces intense pressure from agricultural expansion and inadequate land governance. Understanding the spatial drivers and future trajectories of land-use and land cover (LULC) change is critical for safeguarding the ecosystem services and biodiversity that remnant natural areas provide. This study investigated the relative importance of multiple biophysical, socioeconomic, and demographic drivers of natural ecosystem loss in the Guaporé River Basin (GRB), a 246,300-ha subtropical Atlantic Forest agricultural watershed in southern Brazil. We combined a municipality-level temporal trend analysis to characterize historical LULC dynamics (1998–2019) with the Dinamica EGO cellular automata model, calibrated using Weight of Evidence (WoE), to simulate future landscapes under 2030 and 2050 scenarios. Our results reveal divergent ecological dynamics across the basin. The Northern region experienced extensive remnant vegetation loss (1.55% yr −1 conversion to altered ecosystems), driven by flat terrain and high agricultural productivity, while the Southern region showed partial natural regeneration (1.40% yr −1 transition from altered to regenerating vegetation), linked to steeper slopes and vegetation extraction practices. Despite apparent recovery, closer analysis reveals a regressive process of ecological simplification, in which remnant vegetation is progressively replaced by regenerating vegetation. Future projections suggest that, without strengthened enforcement of Brazil's Natural Vegetation Protection Law, the Northern basin will lose an additional 15,903 ha of remnant vegetation by 2050. These findings highlight critical spatial mismatches between legal protection frameworks and actual land-use pressures, with direct implications for conservation planning, watershed management, and biodiversity protection in the Atlantic Forest biome.","大西洋森林是全球受威胁最严重的生物多样性热点地区之一，面临着农业扩张和土地治理不足带来的巨大压力。理解土地利用与土地覆盖（LULC）变化的空间驱动因素及未来演变趋势，对于维护残余自然区域所提供的生态系统服务和生物多样性至关重要。本研究考察了巴西南部瓜波雷河流域（GRB）自然生态系统丧失的多个生物物理、社会经济和人口驱动因素的相对重要性。该流域面积246,300公顷，属亚热带大西洋森林农业流域。我们将市级时间趋势分析（用于刻画1998—2019年历史LULC动态）与Dinamica EGO元胞自动机模型相结合，并采用证据权重法（WoE）进行校准，以模拟2030年和2050年情景下的未来景观。研究结果揭示了流域内差异化的生态动态。北部地区经历了大面积的残余植被丧失（年转化率1.55%，转为改变后的生态系统），其驱动因素为平坦地形和高农业生产力；而南部地区则表现出部分自然再生（年转化率1.40%，从改变后的生态系统转为再生植被），与较陡的坡度和植被采伐活动相关。尽管表面上呈现恢复态势，进一步分析却揭示了一个退行性的生态简化过程，即残余植被正逐步被再生植被所取代。未来预测表明，若不加紧执行巴西《自然植被保护法》，到2050年北部流域将再丧失15,903公顷残余植被。这些发现凸显了法律保护框架与实际土地利用压力之间的关键空间错配，对大西洋森林生物群系的保护规划、流域管理和生物多样性保护具有直接影响。","Frontiers in Sustainable Food Systems",{"impact":89,"substance":90,"depth":91,"authority":92,"freshness":21,"relevant":22,"comment":343},"基于元胞自动机与证据权重的巴西大西洋森林流域土地利用模拟研究，方法扎实、结论具体，但属区域案例，公共影响有限。",[345],{"name":341,"url":338},[347,27,28,348,349],"农业生态","土地利用变化","流域治理",{"code":48,"slug":233,"name":234,"path":235,"parent_code":111},[],{"status":113,"locked":14,"version":35,"method":36,"evidence":353},{"candidates":354,"agricultural_evidence":41},[355,359],{"code":48,"score":89,"supported":41,"title":356,"abstract":357,"tags":358},[],[27,243,233],[347,348,27],{"code":40,"score":22,"supported":14,"title":360,"abstract":361,"tags":362},[],[],[28],[364,365],"Guaporé River Basin 土地利用","Atlantic Forest 农业流域 模拟","GuaporéRiverBasin土地利用-4738","10.3389\u002Ffsufs.2026.1912707",{"doi":367,"openalex_id":369,"authors":370,"venue":341,"cited_by_count":66,"oa_url":338,"card":378,"direction":72,"ingested_from":74},"W7221477243",[371,374,376],{"name":372,"orcid":373},"Edberto Moura Lima","https:\u002F\u002Forcid.org\u002F0000-0002-8447-8460",{"name":375,"orcid":9},"Bano Mehdi-Schulz",{"name":377,"orcid":9},"Jose Miguel Reichert",{"tldr":379,"method":380,"finding":381,"direction":72,"opportunity":382},"结合趋势分析与元胞自动机模拟巴西大西洋森林农业流域土地利用变化及未来情景。","Dinamica EGO元胞自动机+证据权重法，1998–2019年市级LULC","北部残存植被持续丧失，南部看似恢复实为生态简化，2050年北部将再失1.59万公顷。","可引入遥感时序与多尺度治理数据，量化法律保护与实际压力错配的驱动机制。","2026-10-12T23:30:06.576251Z",{"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":395,"tags":397,"primary_topic":9,"secondary_topics":401,"classification":402,"search_phrases":432,"slug":435,"view_count":66,"doi":436,"paper":437,"created_at":471},4674,"Impact assessment of co-management strategies on forest ecosystem in protected areas of Bangladesh using remote sensing and GIS based analysis","https:\u002F\u002Fdoi.org\u002F10.1007\u002Fs44274-026-01052-0","Co-management of Protected Areas (PAs) has emerged as a strategy to make forest restoration and biodiversity conservation more effective by encouraging the active participation of local people. This study analyzed the co-management effects in two protected areas i.e. Dharmapur Shal Forest and Nawabganj National Park in Dinajpur District, Bangladesh. Land use and land cover change were monitored between 1990 and 2022 using Landsat images. The study considered four main categories: forests, encroached areas, barren lands and water bodies. The findings indicated that forest cover diminished in both forests between 1990 and 2003, but experienced a significant recovery by 2022. The expanse of Dharmapur Shal forest diminished from 552.05 hectares in 1990 to 469.95 hectares in 2003, then rising to 550.41 hectares in 2022. While the forest cover in Nawabganj National Park declined from 454.18 hectares to 393.72 hectares, it recovered to 432.36 hectares in 2022, suggesting a positive association between co-management implementation and forest recovery. However, 2023 ground-truth data indicates that while native Shorea robusta remains dominant (60–65% in Dharmapur; 75–80% in Nawabganj), the forest recovery includes a significant component of exotic plantations ( Acacia and Eucalyptus ) established in previously degraded areas. This suggests a shift in forest composition alongside overall increase in canopy cover. Classification accuracy for 2022 was assessed using a confusion matrix against 120 ground-truth points, achieving an overall accuracy of 86.67% (Kappa = 0.82). Producer's and user's accuracies ranged from 78.57 to 93.33%, with the primary confusion observed between Barren Land and Encroached Area classes. Barren land initially increased and decreased in both areas, while water bodies remained relatively stable. Ecosystem service values (ESVs) related to carbon sequestration, biodiversity and water regulation also improved, based on global valuation coefficients rather than site-specific estimates. Stakeholder perception analysis, including forest officials and local communities, revealed strong support for co-management, citing enhanced forest cover, increased native species and reduced illegal extraction. However, challenges remain in achieving historical biodiversity levels. This study highlights the potential of co-management in forest restoration and sustainable land governance in developing countries and provides evidence-based insights to inform future policy and planning.","保护区（Protected Areas, PAs）共管已成为一种策略，通过鼓励当地民众积极参与，使森林恢复和生物多样性保护更加有效。本研究分析了孟加拉国迪纳杰布尔县两个保护区的共管效果，即达尔马普尔娑罗林和纳瓦布根杰国家公园。利用Landsat影像监测了1990年至2022年间的土地利用与土地覆盖变化。研究考虑了四个主要类别：森林、侵占区、裸地和水体。研究结果表明，1990年至2003年间，两处森林的森林覆盖均有所减少，但到2022年经历了显著恢复。达尔马普尔娑罗林面积从1990年的552.05公顷减少至2003年的469.95公顷，随后在2022年增至550.41公顷。纳瓦布根杰国家公园的森林覆盖从454.18公顷下降至393.72公顷，但在2022年恢复至432.36公顷，表明共管实施与森林恢复之间存在正相关关系。然而，2023年地面实况数据表明，尽管本地娑罗双树（Shorea robusta）仍占主导地位（达尔马普尔为60–65%；纳瓦布根杰为75–80%），但森林恢复中包含了大量在先前退化区域建立的外来人工林（金合欢属和桉属）。这表明森林组成发生了转变，同时冠层覆盖总体增加。利用混淆矩阵对2022年分类精度进行了评估，以120个地面实况点为参照，总体精度达到86.67%（Kappa = 0.82）。生产者精度和用户精度范围为78.57%至93.33%，主要混淆出现在裸地和侵占区类别之间。两处区域的裸地均呈现先增后减的趋势，而水体保持相对稳定。基于全球估值系数而非特定地点估算，与碳固存、生物多样性和水资源调节相关的生态系统服务价值（ESVs）也有所改善。利益相关者感知分析（包括林业官员和当地社区）显示，各方对共管给予强烈支持，理由包括森林覆盖增加、本地物种增多以及非法采伐减少。然而，在达到历史生物多样性水平方面仍存在挑战。本研究凸显了共管在发展中国家森林恢复和可持续土地治理中的潜力，并提供了基于证据的见解，以期为未来","Discover Environment","2026-10-09T00:00:00Z",71,{"impact":89,"substance":280,"depth":19,"authority":20,"freshness":17,"relevant":22,"comment":394},"基于Landsat遥感与GIS的孟加拉国保护区共管成效评估，方法规范、数据翔实，对发展中国家森林治理有参考价值，但与国内三农及农业信息化直接关联较弱。",[396],{"name":390,"url":387},[27,28,398,399,400],"土地利用","森林保护","社区共管",[],{"status":34,"locked":14,"version":35,"method":36,"evidence":403},{"candidates":404,"agricultural_evidence":14,"reason":53},[405,411,415,420,426],{"code":48,"score":406,"supported":41,"title":407,"abstract":408,"tags":410},11,[],[27,243,233,409],"ecosystem service",[398,27],{"code":40,"score":21,"supported":41,"title":412,"abstract":413,"tags":414},[45],[],[28],{"code":310,"score":17,"supported":41,"title":416,"abstract":418,"tags":419},[417],"GIS",[],[],{"code":421,"score":187,"supported":41,"title":422,"abstract":423,"tags":425},"H3",[],[424],"水资源",[],{"code":427,"score":187,"supported":41,"title":428,"abstract":429,"tags":431},"H4",[],[430],"carbon sequestration",[],[433,434],"孟加拉国 保护区 森林共管","Landsat 遥感 森林覆盖变化","孟加拉国保护区森林共管-4674","10.1007\u002Fs44274-026-01052-0",{"doi":436,"openalex_id":438,"authors":439,"venue":390,"cited_by_count":66,"oa_url":464,"card":465,"direction":470,"ingested_from":74},"W7221074353",[440,442,445,447,450,453,455,457,459,462],{"name":441,"orcid":9},"Md Manik Ali",{"name":443,"orcid":444},"Sudipto Saha Dipto","https:\u002F\u002Forcid.org\u002F0000-0001-6479-9593",{"name":446,"orcid":9},"Md Shafiqul Bari",{"name":448,"orcid":449},"Mahmuod Abubakar Bashir","https:\u002F\u002Forcid.org\u002F0000-0002-6296-8522",{"name":451,"orcid":452},"Nazmin Akter","https:\u002F\u002Forcid.org\u002F0009-0006-7337-2798",{"name":454,"orcid":9},"Sujan Kumar Shil",{"name":456,"orcid":9},"Md Farid Hasan",{"name":458,"orcid":9},"Md Asif Adnan Prince",{"name":460,"orcid":461},"Muhammad Madnee","https:\u002F\u002Forcid.org\u002F0000-0002-1362-7473",{"name":463,"orcid":9},"Abdullahi Omar Mohamud","https:\u002F\u002Flink.springer.com\u002Fcontent\u002Fpdf\u002F10.1007\u002Fs44274-026-01052-0.pdf",{"tldr":466,"method":467,"finding":468,"direction":72,"opportunity":469},"评估孟加拉国两个保护区共管策略对森林生态的影响，发现森林覆盖先减后增但树种组成改变。","用1990-2022年Landsat影像做土地利用分类，结合地面验证与利益相关者","共管后森林覆盖显著恢复，但恢复中混入大量外来树种，原生生物多样性未完全恢复。","可延伸研究共管政策下外来树种扩张对碳汇与生物多样性的长期权衡，并开发本地化生态服务估值模型。","智慧农业 \u002F 农业物联网","2026-10-11T23:30:17.636276Z"]
