agricultural practice that combines production with sustainability. In the Eastern Amazon region, this system is used to harvest native fruits such as açaí and cacao. However, different management strategies may be associated with contrasting biochemical and molecular characteristics of these fruits. To evaluate these differences, a comparative observational analysis of açaí pulps and cacao seeds with adhering arils was performed using samples from two neighboring agroforestry systems in Tomé-Açu (Pará, Brazil), with one farm representing an organic management regime (AFS19) and the other representing a conventional management regime (AFS27). The analysis focused on trace element composition, metabolic diversity, and gene expression. The elemental composition of the fruits was broadly similar, although açaí from AFS19 had 35% and 38% higher concentrations of phosphorus and copper, respectively, while cacao from AFS27 had 17%–30% higher concentrations of calcium, manganese, magnesium, and sulfur. The metabolic profiles of both açaí and cacao from AFS19 were more diverse and included several putative compounds, such as apigenin and esculin, tentatively annotated only in samples from AFS19. Transcriptomic data showed that açaí pulps from AFS19 had higher expression of genes associated with antioxidative processes and stress resistance, whereas AFS27 showed higher expression of genes related to ripening, proteolysis, and flavonoid biosynthesis. In cacao seeds, AFS19 showed higher expression of transcripts associated with seed protection and carbohydrate metabolism on reserve mobilization, while AFS27 showed higher expression of genes related to pathogen resistance, seed coating, and maturation. Overall, the combined analysis revealed distinct biochemical and transcriptomic profiles between the two agroforestry systems, providing comparative data on fruit characteristics associated with contrasting management regimes in tropical agroforestry systems.","农林复合经营是一种将生产与可持续性相结合的农业实践。在东亚马逊地区，该系统被用于采收巴西莓（açaí）和可可等本土果实。然而，不同的管理策略可能与该类果实在生化和分子特征上的差异相关。为评估这些差异，本研究对来自巴西帕拉州托梅-阿苏（Tomé-Açu）两个相邻农林复合系统的巴西莓果肉和带假种皮的可可种子进行了比较性观察分析，其中一个农场代表有机管理方式（AFS19），另一个代表常规管理方式（AFS27）。分析聚焦于微量元素组成、代谢多样性和基因表达。果实的元素组成总体相似，但AFS19的巴西莓中磷和铜的浓度分别高出35%和38%，而AFS27的可可中钙、锰、镁和硫的浓度高出17%–30%。AFS19的巴西莓和可可的代谢谱均更为多样，并包含若干推定化合物，如芹菜素（apigenin）和秦皮苷（esculin），这些化合物仅在AFS19样品中被初步注释。转录组数据显示，AFS19的巴西莓果肉中与抗氧化过程和抗逆性相关的基因表达更高，而AFS27中与成熟、蛋白质水解和类黄酮生物合成相关的基因表达更高。在可可种子中，AFS19中与种子保护和碳水化合物代谢（储备动员）相关的转录本表达更高，而AFS27中与病原体抗性、种子包被和成熟相关的基因表达更高。总体而言，联合分析揭示了两类农林复合系统之间不同的生化和转录组谱，为热带农林复合系统中与不同管理方式相关的果实特征提供了比较数据。","Frontiers in Sustainable Food Systems","2026-10-16T00:00:00Z",64,{"impact":16,"substance":155,"depth":88,"authority":156,"freshness":20,"relevant":21,"comment":157},18,13,"该研究对比了亚马逊东部有机与常规管理下巴西莓和可可的生化与转录组差异，方法扎实、数据具体，但属区域性基础研究，公共影响有限，适合作为论文类资讯收录，不进入每日精选。",[159],{"name":151,"url":148},[28,161,162,163,164],"亚马逊水果","代谢组学","转录组学","有机管理",{"code":166,"slug":167,"name":168,"path":169,"parent_code":170},"B3","tea-coffee","茶叶与咖啡","\u002Ftopic\u002Fhorticulture\u002Ftea-coffee","B",[],{"status":106,"locked":13,"version":33,"method":34,"evidence":173},{"candidates":174,"agricultural_evidence":42},[175],{"code":166,"score":19,"supported":42,"title":176,"abstract":178,"tags":180},[177],"cacao",[179,177],"可可",[],[182,183],"Tomé-Açu 农林复合系统 巴西莓","可可 农林复合系统 转录组","Tomé-Açu农林复合系统巴西莓-5142","10.3389\u002Ffsufs.2026.1970644",{"doi":185,"openalex_id":187,"authors":188,"venue":151,"cited_by_count":69,"oa_url":201,"card":202,"direction":206,"ingested_from":70},"W7222624325",[189,191,193,195,197,199],{"name":190,"orcid":8},"R.

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":16,"substance":155,"depth":88,"authority":156,"freshness":16,"relevant":21,"comment":219},"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。",[221],{"name":215,"url":212},[223,224,225,27,226],"遥感监测","土地利用变化","流域管理","空间规划",{"code":38,"slug":228,"name":229,"path":230,"parent_code":231},"biodiversity","生态保护与生物多样性","\u002Ftopic\u002Fenvironment\u002Fbiodiversity","H",[233],{"code":234,"slug":235,"name":236,"path":237,"parent_code":238},"I4","gis","GIS与空间分析","\u002Ftopic\u002Fdigital-agriculture\u002Fgis","I",{"status":106,"locked":13,"version":33,"method":34,"evidence":240},{"candidates":241,"agricultural_evidence":42},[242,247,255,262],{"code":38,"score":156,"supported":42,"title":243,"abstract":245,"tags":246},[244],"ecosystem service",[27],[224,27],{"code":234,"score":12,"supported":42,"title":248,"abstract":249,"tags":254},[],[250,251,252,253],"地理信息","空间分析","GIS","spatial analysis",[226],{"code":130,"score":256,"supported":42,"title":257,"abstract":258,"tags":261},7,[],[259,260],"遥感","remote sensing",[223],{"code":263,"score":124,"supported":42,"title":264,"abstract":265,"tags":267},"D",[],[266],"渔业",[],[269,270],"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":272,"openalex_id":274,"authors":275,"venue":215,"cited_by_count":69,"oa_url":288,"card":289,"direction":293,"ingested_from":70},"W7221789653",[276,279,282,285],{"name":277,"orcid":278},"Safril Kasim","https:\u002F\u002Forcid.org\u002F0009-0009-4679-4233",{"name":280,"orcid":281},"Hasddin Hasddin","https:\u002F\u002Forcid.org\u002F0000-0002-0114-5274",{"name":283,"orcid":284},"La Fariki","https:\u002F\u002Forcid.org\u002F0009-0003-7870-9028",{"name":286,"orcid":287},"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":290,"method":291,"finding":292,"direction":293,"opportunity":294},"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。","农业遥感与作物表型","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",{"id":297,"title":298,"url":299,"summary":300,"summary_zh":301,"content":8,"source_name":151,"source_url":299,"published_at":302,"category":11,"cover_url":8,"hotness":12,"is_selected":13,"score":303,"score_detail":304,"sources":307,"tags":309,"primary_topic":313,"secondary_topics":318,"classification":319,"search_phrases":333,"slug":336,"view_count":69,"doi":337,"paper":338,"created_at":350},5070,"Threshold effects in exchange rate pass-through to food prices in emerging market economies","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1960606","Whether food price movements in emerging market economies are associated more closely with energy costs or exchange rate fluctuations is an important question for food security policy. This study examines this issue using a balanced monthly panel of 17 emerging market economies from January 2006 to December 2023. Country-specific cumulative pass-through coefficients are first estimated and then examined in relation to observable structural characteristics. State dependence is assessed using a threshold specification based on observed 12-month food inflation, complemented by quantile regressions across the conditional distribution. The results indicate considerable heterogeneity in exchange rate pass-through across countries. The mean cumulative coefficient is 0.213, with individual estimates ranging from −0.012 to 0.807. Pass-through also appears to vary with the inflation environment. Threshold estimates suggest a transition point between 6.8 and 7.6 percent annual food inflation, above which the response of food prices to exchange rate movements tends to become stronger. Within-country mean-group estimates provide further support for this interpretation, suggesting that the observed regime differences are not solely attributable to country composition. The estimated effect is higher in the high-inflation state in all eight economies for which both states can be reliably estimated. By comparison, the cumulative effect of crude oil prices is modest: 0.008 over 6 months, which is not statistically distinguishable from zero, rising to 0.064 over 18 months and becoming statistically detectable. The results do not provide consistent evidence of comparable state dependence in either the energy price or global commodity price channel. Similarly, structural indicators such as food import dependence, energy dependence, and fertilizer import dependence do not appear to account systematically for cross-country variation in pass-through. Overall, the findings suggest that exchange rate movements may play a relatively greater role in consumer food price dynamics than energy price movements in the emerging market economies considered, particularly during periods of elevated food inflation. The results also suggest that macro-financial stability may be relevant for food price stabilization and that the effectiveness of trade-based policy measures may depend on the relative importance of exchange rate transmission.","对于新兴市场经济体的粮食价格波动与能源成本还是汇率波动关联更密切，这是粮食安全政策的一个重要问题。本研究利用2006年1月至2023年12月17个新兴市场经济体的平衡月度面板数据考察了这一问题。首先估计了各国特定的累积传递系数，然后考察其与可观测结构性特征的关系。状态依赖性通过基于观测到的12个月粮食通胀率的阈值设定进行评估，并辅以条件分布上的分位数回归。结果表明，汇率传递在不同国家之间存在相当大的异质性。平均累积系数为0.213，各国估计值从−0.012到0.807不等。传递效应似乎也随通胀环境而变化。阈值估计表明，年度粮食通胀率在6.8%至7.6%之间存在一个转变点，高于该点时粮食价格对汇率波动的反应趋于增强。组内均值组估计进一步支持了这一解释，表明所观察到的状态差异并非仅归因于国家构成。在能够可靠估计两种状态的八个经济体中，高通胀状态下的估计效应均更高。相比之下，原油价格的累积效应较为有限：6个月内为0.008，与零无统计显著差异，18个月内升至0.064并具有统计可检测性。结果并未提供一致证据表明能源价格渠道或全球商品价格渠道存在类似的状态依赖性。同样，粮食进口依赖度、能源依赖度和化肥进口依赖度等结构性指标似乎也无法系统性地解释传递效应的跨国差异。总体而言，研究结果表明，在所考察的新兴市场经济体中，汇率波动在消费者粮食价格动态中可能比能源价格波动发挥相对更大的作用，尤其是在粮食通胀高企时期。结果还表明，宏观金融稳定可能与粮食价格稳定相关，而贸易类政策措施的有效性可能取决于汇率传递的相对重要性。","2026-10-15T00:00:00Z",79,{"impact":155,"substance":305,"depth":155,"authority":156,"freshness":16,"relevant":21,"comment":306},22,"基于17个新兴市场国家2006—2023年月度面板数据，发现食品通胀6.8%—7.6%的门槛效应，对粮食安全与宏观政策有参考价值，但属学术论文，公共传播性有限。",[308],{"name":151,"url":299},[26,94,310,311,312],"食品价格","新兴市场","汇率传导",{"code":136,"slug":314,"name":315,"path":316,"parent_code":317},"yield-food-security","单产提升与粮食安全","\u002Ftopic\u002Ffield-crops\u002Fyield-food-security","A",[],{"status":106,"locked":13,"version":33,"method":34,"evidence":320},{"candidates":321,"agricultural_evidence":42},[322,327],{"code":136,"score":256,"supported":42,"title":323,"abstract":324,"tags":326},[],[94,325],"food security",[94],{"code":328,"score":124,"supported":42,"title":329,"abstract":330,"tags":332},"F3",[],[331],"fertilizer",[],[334,335],"新兴市场 汇率传导 食品价格","食品通胀 门槛效应","新兴市场汇率传导食品价格-5070","10.3389\u002Ffsufs.2026.1960606",{"doi":337,"openalex_id":339,"authors":340,"venue":151,"cited_by_count":69,"oa_url":299,"card":344,"direction":348,"ingested_from":70},"W7222138848",[341],{"name":342,"orcid":343},"Fatma İlknur ÜNÜVAR","https:\u002F\u002Forcid.org\u002F0000-0001-5371-8604",{"tldr":345,"method":346,"finding":347,"direction":348,"opportunity":349},"研究17个新兴市场汇率对食品价格的传递效应及其通胀阈值。","2006-2023年月度面板，阈值回归与分位数回归估计传递系数。","汇率传递异质性大，食品通胀超6.8%-7.6%后传递显著增强，油价影响微弱。","农业人工智能与决策模型","可结合宏观金融稳定与食品通胀阈值，研究汇率传递对粮食安全政策与贸易措施有效性的影响。","2026-10-16T23:30:06.270998Z",{"id":352,"title":353,"url":354,"summary":355,"summary_zh":356,"content":8,"source_name":357,"source_url":354,"published_at":358,"category":11,"cover_url":8,"hotness":12,"is_selected":13,"score":359,"score_detail":360,"sources":363,"tags":365,"primary_topic":8,"secondary_topics":369,"classification":370,"search_phrases":387,"slug":390,"view_count":69,"doi":391,"paper":392,"created_at":422},4886,"Mapping Fuel Categories in Mediterranean Regions with Sentinel-2 and PlanetScope Satellite Acquisitions","https:\u002F\u002Fdoi.org\u002F10.5194\u002Fisprs-archives-xlviii-m-13-2026-9-2026","Accurate and spatially explicit mapping of forest fuel types is essential for developing integrated wildfire risk management strategies, estimating fire danger, and modeling fire propagation in fire-prone Mediterranean ecosystems. While time series of Copernicus Sentinel-2 multispectral imagery at 10 m spatial resolution have proven effective for regional fuel mapping, severe spectral and spatial ambiguities persist in distinguishing complex canopy structures, heterogeneous shrublands, and pastures. This study explores the synergistic integration of Sentinel-2 time series and high-resolution PlanetScope satellite acquisitions (3 m spatial resolution) to produce a 10 m fuel type map (9 classes) over a pilot area in Sardinia, Italy. A total of 114 features were synthesized, combining dynamic Sentinel-2 metrics (kNDVI, FAPAR, NDMI, ReNDVI harmonics), PlanetScope seasonal kNDVI zonal statistics and Gray-Level Co-occurrence Matrix (GLCM) textural features, and static terrain\u002Fcanopy parameters. Using an XGBoost machine learning classifier trained on 245 photo-interpreted Regions of Interest (80\u002F20 spatial split), three sets of features were compared. The combined model achieved a test overall accuracy of 74.46%, compared to 74.05% for Sentinel-2 alone and 74.66% for PlanetScope alone. Notably, incorporating PlanetScope textural features significantly improved classification metrics for dense canopy classes, increasing the F1-score of broadleaf evergreen trees and needleleaf evergreen trees. The PlanetScope GLCM kNDVI autumn entropy emerged as the most important feature overall. Conversely, PlanetScope performed poorly on the grass class. These findings highlight the critical trade-offs and high complementarity between fine spatial texture and broad spectral coverage for operational wildfire management.","在易发生火灾的地中海生态系统中，准确且具有空间明确性的森林可燃物类型制图对于制定综合野火风险管理策略、估算火险以及模拟火蔓延至关重要。尽管10 m空间分辨率的哥白尼Sentinel-2多光谱影像时间序列已被证明对区域可燃物制图有效，但在区分复杂冠层结构、异质性灌丛和草地时，仍存在严重的光谱和空间模糊性。本研究探索了Sentinel-2时间序列与高分辨率PlanetScope卫星影像（3 m空间分辨率）的协同集成，以在意大利撒丁岛的一个试验区生成10 m可燃物类型图（9类）。共合成114个特征，结合了动态Sentinel-2指标（kNDVI、FAPAR、NDMI、ReNDVI谐波）、PlanetScope季节性kNDVI分区统计和灰度共生矩阵（GLCM）纹理特征，以及静态地形\u002F冠层参数。使用在245个照片判读感兴趣区（80\u002F20空间划分）上训练的XGBoost机器学习分类器，比较了三组特征。组合模型的测试总体精度为74.46%，而仅使用Sentinel-2为74.05%，仅使用PlanetScope为74.66%。值得注意的是，纳入PlanetScope纹理特征显著改善了密集冠层类的分类指标，提高了阔叶常绿乔木和针叶常绿乔木的F1分数。PlanetScope GLCM kNDVI秋季熵成为总体最重要的特征。相反，PlanetScope在草地类上表现较差。这些发现凸显了精细空间纹理与广域光谱覆盖在业务化野火管理中的关键权衡和高互补性。","˜The œinternational archives of the photogrammetry, remote sensing and spatial information sciences\u002FInternational archives of the photogrammetry, remote sensing and spatial information sciences","2026-10-12T00:00:00Z",72,{"impact":361,"substance":305,"depth":18,"authority":156,"freshness":16,"relevant":21,"comment":362},12,"方法新颖、数据扎实的遥感制图论文，对林火风险管理有参考价值，但属细分领域研究，公共影响有限。",[364],{"name":357,"url":354},[366,367,223,29,368],"Sentinel-2","机器学习","林火风险",[],{"status":371,"locked":13,"version":33,"method":34,"evidence":372},"needs_review",{"candidates":373,"agricultural_evidence":13,"reason":386},[374,380],{"code":375,"score":256,"supported":42,"title":376,"abstract":377,"tags":379},"I2",[],[367,378],"machine learning",[367],{"code":130,"score":381,"supported":42,"title":382,"abstract":383,"tags":385},5,[],[384],"multispectral",[366,223],"农业相关性需要复核",[388,389],"Sentinel-2 PlanetScope 燃料类型制图","撒丁岛 林火燃料 遥感","Sentinel-2PlanetScope燃料类型制图-4886","10.5194\u002Fisprs-archives-xlviii-m-13-2026-9-2026",{"doi":391,"openalex_id":393,"authors":394,"venue":357,"cited_by_count":69,"oa_url":415,"card":416,"direction":421,"ingested_from":70},"W7221532579",[395,398,401,403,406,409,412],{"name":396,"orcid":397},"Federico Filipponi","https:\u002F\u002Forcid.org\u002F0000-0002-1419-3734",{"name":399,"orcid":400},"Daniela Stroppiana","https:\u002F\u002Forcid.org\u002F0000-0002-5619-4305",{"name":402,"orcid":8},"Forough Rajabi",{"name":404,"orcid":405},"Debora Voltolina","https:\u002F\u002Forcid.org\u002F0000-0001-9186-0644",{"name":407,"orcid":408},"Bachisio Arca","https:\u002F\u002Forcid.org\u002F0000-0002-2834-2753",{"name":410,"orcid":411},"Michele Salis","https:\u002F\u002Forcid.org\u002F0000-0002-0499-9726",{"name":413,"orcid":414},"Francesco Zucca","https:\u002F\u002Forcid.org\u002F0000-0003-4119-5484","https:\u002F\u002Fisprs-archives.copernicus.org\u002Farticles\u002FXLVIII-M-13-2026\u002F9\u002F2026\u002Fisprs-archives-XLVIII-M-13-2026-9-2026.pdf",{"tldr":417,"method":418,"finding":419,"direction":293,"opportunity":420},"融合Sentinel-2时序与PlanetScope高分影像，用XGBoost绘制地中海9类可燃物类","Sentinel-2时序谐波、PlanetScope kNDVI与GLCM纹理及","联合模型精度74.46%，PlanetScope纹理显著提升密冠层F1，但草地类表现差。","可探索多源高分纹理与光谱互补机制，优化稀疏植被与草地类别的特征设计。","智慧农业 \u002F 农业物联网","2026-10-14T23:30:11.734574Z",{"id":424,"title":425,"url":426,"summary":427,"summary_zh":428,"content":8,"source_name":429,"source_url":426,"published_at":430,"category":11,"cover_url":8,"hotness":12,"is_selected":13,"score":303,"score_detail":431,"sources":433,"tags":435,"primary_topic":8,"secondary_topics":439,"classification":440,"search_phrases":470,"slug":473,"view_count":69,"doi":474,"paper":475,"created_at":490},4584,"Farmland Transformation Reshapes Ecosystem Services Through Multi-Level Landscape Reconfiguration: Evidence from China’s Songnen Plain","https:\u002F\u002Fdoi.org\u002F10.3390\u002Fagriculture16202188","Global agricultural expansion has profoundly reshaped terrestrial landscapes, yet the ecological consequences of farmland transformation across multiple spatial scales remain insufficiently understood. This study investigates how farmland dynamics influence ecosystem service (ES) provision in China’s Songnen Plain by integrating long-term land-use trajectories, remote sensing data, and landscape ecological analysis. Using annual 30 m land-use\u002Fland-cover datasets from 2000 to 2020, we identified diverse farmland transformation pathways, including stable cultivation, reclamation, abandonment, fallow, afforestation, and urban encroachment. The InVEST model was applied to quantify three key ecosystem services: food supply, soil conservation, and carbon storage, while grid-level Partial Least Squares Regression (PLSR) was employed to identify their major drivers. Results revealed substantial spatial and temporal heterogeneity in ecosystem services. Food supply and soil conservation generally increased during the study period, whereas carbon storage exhibited a declining trend. Landscape-level characteristics, particularly Shannon diversity index (SHDI), aggregation index (AI), and patch density (PD), were identified as dominant factors regulating ecosystem service variation. Class-level indicators, including farmland area (FA) and mean patch area (MPA), also showed significant but comparatively weaker effects. This study provides new insights into the ecological consequences of intensive farmland transformation and highlights the importance of optimizing multi-scale landscape configurations to balance agricultural production and ecosystem sustainability.","全球农业扩张深刻重塑了陆地景观格局，但农田转型在多个空间尺度上的生态效应仍缺乏充分认识。本研究通过整合长期土地利用轨迹、遥感数据和景观生态分析，探讨了农田动态如何影响中国松嫩平原的生态系统服务（ES）供给。基于2000—2020年逐年30 m土地利用\u002F土地覆盖数据集，我们识别了多种农田转型路径，包括稳定耕作、开垦、撂荒、休耕、退耕还林和城市侵占。应用InVEST模型量化了粮食供给、土壤保持和碳储量三项关键生态系统服务，并采用格网级偏最小二乘回归（PLSR）识别其主要驱动因子。结果表明，生态系统服务存在显著的空间和时间异质性。粮食供给和土壤保持总体上在研究期间呈增加趋势，而碳储量则表现出下降趋势。景观尺度特征，特别是香农多样性指数（SHDI）、聚集度指数（AI）和斑块密度（PD），被识别为调控生态系统服务变化的主导因子。类型尺度指标，包括农田面积（FA）和平均斑块面积（MPA），也表现出显著但相对较弱的影响。本研究为集约化农田转型的生态后果提供了新见解，并强调了优化多尺度景观格局以平衡农业生产与生态系统可持续性的重要性。","Agriculture","2026-10-09T00:00:00Z",{"impact":155,"substance":305,"depth":155,"authority":156,"freshness":16,"relevant":21,"comment":432},"基于2000—2020年30米土地利用数据与InVEST模型，揭示松嫩平原农田转型对生态系统服务的多尺度影响，方法与数据扎实，对黑土地保护与农业可持续布局有参考价值。",[434],{"name":429,"url":426},[436,437,223,438,27],"农业遥感","黑土地保护","土地利用",[],{"status":371,"locked":13,"version":33,"method":34,"evidence":441},{"candidates":442,"agricultural_evidence":42,"reason":469},[443,447,451,458,464],{"code":38,"score":16,"supported":42,"title":444,"abstract":445,"tags":446},[],[27,244],[438,27],{"code":130,"score":16,"supported":42,"title":448,"abstract":449,"tags":450},[],[259,260],[436,223],{"code":452,"score":73,"supported":42,"title":453,"abstract":454,"tags":457},"H2",[],[455,456],"土壤","soil",[],{"code":459,"score":124,"supported":42,"title":460,"abstract":461,"tags":463},"J3",[],[462],"全球农业",[],{"code":465,"score":21,"supported":13,"title":466,"abstract":467,"tags":468},"H1",[],[],[437],"多个产业证据相当，需要确认主归属",[471,472],"松嫩平原 农田转型 生态系统服务","InVEST模型 碳储量 土壤保持","松嫩平原农田转型生态系统服务-4584","10.3390\u002Fagriculture16202188",{"doi":474,"openalex_id":476,"authors":477,"venue":429,"cited_by_count":69,"oa_url":426,"card":485,"direction":293,"ingested_from":70},"W7221099965",[478,480,483],{"name":479,"orcid":8},"Ruhao Xue",{"name":481,"orcid":482},"Bonoua Faye","https:\u002F\u002Forcid.org\u002F0000-0003-4465-6792",{"name":484,"orcid":8},"Hu Xie",{"tldr":486,"method":487,"finding":488,"direction":206,"opportunity":489},"基于松嫩平原2000-2020年土地利用数据，揭示耕地转型通过多尺度景观格局重塑生态系统服务。","30米土地利用数据、InVEST模型与网格级偏最小二乘回归（PLSR）。","食物供给与土壤保持增加而碳储量下降，景观格局指数是主导驱动因子。","可探究不同耕地转型路径对碳储量的非线性影响及多尺度景观优化配置阈值。","2026-10-10T23:30:27.812095Z"]
