Methods Focusing on China’s major rice-producing areas (MRPAs), we developed a spatially explicit resilience framework that integrates internal adaptive capacities and external socio-economic conditions, and examined the spatial and temporal patterns of cultivated land system resilience using three representative years (2000, 2010, and 2023). We quantified resilience, diagnosed dominant constraints via an obstacle model, and developed differentiated regulation pathways based on the identified constraints. Results Results show that: (1) overall resilience increased with fluctuations, with a growing role of socio-economic conditions alongside persistent environmental constraints. This improvement coincided with infrastructure development and policy interventions, although urbanization pressures may have constrained resilience in peri-urban areas. (2) resilience exhibited marked spatial differentiation. Large-scale agricultural regions maintained higher resilience, coinciding with favorable natural endowments and relatively well-developed infrastructure, whereas fragmented and highly urbanized areas remained more vulnerable amid intensified human–land conflicts. (3) dominant obstacles shifted from natural background constraints to socio-economic factors over time. Four regulation zones were identified: background-restricted low-resilience, external-stress resilience risk, resource-constrained lagging recovery, and market-sensitive hidden risk. Discussion These findings provide a diagnostic basis for differentiated management by tailoring strategies to region-specific resilience constraints.","引言 耕地系统面临土地利用变化、农田边际化和饮食升级等多重趋同压力，因此理解其韧性对于维持农业功能和粮食安全至关重要。方法 本文以中国水稻主产区为研究区，构建了一个整合内部适应能力与外部社会经济条件的空间显式韧性框架，并选取2000年、2010年和2023年三个代表性年份，考察耕地系统韧性的时空格局。我们量化了韧性水平，通过障碍度模型诊断了主导约束因子，并基于识别出的约束条件提出了差异化调控路径。结果 结果表明：(1) 总体韧性呈波动上升趋势，社会经济条件的作用不断增强，而环境约束持续存在。这一改善与基础设施建设和政策干预相吻合，尽管城市化压力可能制约了城郊地区的韧性提升。(2) 韧性表现出显著的空间分异。大规模农业区域维持了较高的韧性，这与有利的自然禀赋和相对完善的基础设施相吻合，而破碎化程度高和高度城市化的区域在人地矛盾加剧的背景下仍较为脆弱。(3) 主导障碍因子随时间推移从自然本底约束转向社会经济因素。研究识别出四类调控分区：本底限制型低韧性区、外部胁迫型韧性风险区、资源约束型滞后恢复区和市场敏感型隐性风险区。讨论 这些发现为因地制宜制定差异化策略、针对区域特定韧性约束实施差异化管理提供了诊断依据。",null,"Frontiers in Sustainable Food

for national food security, yet traditional ground-based estimation methods in Bangladesh often lack precision. This study develops a robust machine-learning framework to map Boro rice in the Manikganj district by integrating Sentinel-1 Synthetic Aperture Radar (SAR) and Sentinel-2 optical imagery. To overcome the challenge of seasonal cloud cover, Sentinel-1 VH polarization was utilized to identify unique backscatter reductions during the transplantation phase (late February to early March) caused by specular reflection from flooded fields. By combining these SAR signatures with high-resolution spectral indices (NDVI, EVI, and BSI) from Sentinel-2 during peak growth stages, the research captures the distinct phenological signatures of paddy rice. A pixel-based Random Forest algorithm was applied within the Google Earth Engine (GEE) platform, utilizing about 200 field-verified reference points per sub-district (1,385 in total) for training and validation. The results demonstrated high classification performance, with overall accuracies ranging from 88.1% to 94.9% across the seven sub-districts. Furthermore, a comparison with official government statistics revealed a minimal total area difference of only 2.34%, underscoring the reliability of this integrated satellite approach for operational crop monitoring.","准确的当季作物制图对国家粮食安全至关重要，然而孟加拉国传统的基于地面估计的方法往往缺乏精度。本研究开发了一个稳健的机器学习框架，通过整合Sentinel-1合成孔径雷达（SAR）和Sentinel-2光学影像，对马尼格甘杰县的Boro水稻进行制图。为克服季节性云覆盖的挑战，研究利用Sentinel-1 VH极化识别插秧期（2月下旬至3月上旬）由淹水田块镜面反射所引起的独特后向散射降低特征。通过将这些SAR特征与Sentinel-2在生长旺盛期的高分辨率光谱指数（NDVI、EVI和BSI）相结合，研究捕捉到了水稻独特的物候特征。在Google Earth Engine（GEE）平台上应用了基于像元的随机森林算法，利用每个乡约200个实地验证参考点（共计1，385个）进行训练和验证。结果表明分类性能较高，七个乡的总体精度在88.1%至94.9%之间。此外，与政府官方统计数据相比，总面积差异仅为2.34%，凸显了这种综合卫星方法在业务化作物监测中的可靠性。","OpenAlex","2026-10-18T00:00:00Z",79,{"impact":17,"substance":18,"depth":17,"authority":151,"freshness":20,"relevant":21,"comment":191},"方法扎实、精度可靠的水稻遥感制图研究，对农业遥感业务化监测有参考价值，但属区域性案例，影响层级有限。",[193],{"name":187,"url":184},[34,27,195,196,197],"机器学习","作物制图","遥感",{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},[],{"status":39,"locked":14,"version":40,"method":41,"evidence":201},{"candidates":202,"agricultural_evidence":46},[203,208,212,218],{"code":32,"score":17,"supported":46,"title":204,"abstract":205,"tags":207},[33],[34,33,206],"paddy",[34],{"code":51,"score":52,"supported":46,"title":209,"abstract":210,"tags":211},[],[27,55],[27],{"code":213,"score":214,"supported":46,"title":215,"abstract":216,"tags":217},"I2",4,[],[195],[195],{"code":58,"score":21,"supported":14,"title":219,"abstract":220,"tags":221},[],[],[197],[223,224],"Sentinel-1 Sentinel-2 水稻制图","孟加拉国 Boro 水稻 遥感","Sentinel-1Sentinel-2水稻制图-5319","10.31223\u002Fx5f22w",{"doi":226,"openalex_id":228,"authors":229,"venue":9,"cited_by_count":82,"oa_url":242,"card":243,"direction":247,"ingested_from":89},"W7222810209",[230,232,235,238,240],{"name":231,"orcid":9},"Mst.

1](http:\u002F\u002Fpic1.nmgnews.com.cn\u002F003\u002F011\u002F304\u002F00301130409_236751ec.png)\n\n从三系法到两系法，我国杂交水稻品种不断迭代升级，为保障国家粮食安全作出了重大贡献。但传统杂交水稻制种存在制种工作较繁琐，制种投入大、风险较高的问题，在一定程度上制约了优良杂交水稻组合在更大范围内的推广。如何固定水稻的杂种优势，使优良杂交品种能通过种子实现连续繁殖，是杂交水稻育种家长期追求的重大科学目标。\n\n1987年，中国工程院院士袁隆平提出了杂交稻由“三系法”向“两系法”，最终向“一系法”发展的伟大战略构想。“一系法”的核心便是固定杂种优势，使优良杂交种能通过自身种子连续繁殖，实现“一次杂交、代代可用”。人工无融合生殖是一种通过重新设计植物生殖过程，使杂交种产生与自身遗传组成基本一致的克隆种子，为实现这一战略目标提供了新的技术路径。一旦能实现稳定产业化应用，该方法有望从根本上简化杂交稻种子生产体系，降低制种成本和风险，推动杂交稻向固定和连续繁殖优良杂合基因型转变。\n\n![Image 2](http:\u002F\u002Fpic1.nmgnews.com.cn\u002F003\u002F011\u002F304\u002F00301130410_12de709f.png)\n\n据此，崖州湾实验室牵头，协同中国农业科学院作物科学研究所、中国水稻研究所、湖南省农业科学院、安徽省农业科学院、袁隆平农业高科技股份有限公司和安徽荃银高科种业股份有限公司等优势团队，针对水稻克隆效率、结实能力、遗传背景适用性和田间稳定性等关键问题启动联合攻关。团队将生殖调控研究、材料创制、多代繁殖和田间评价相衔接，在“一系法”杂交水稻制种技术这一颠覆性原始创新攻关中取得了从高效克隆到多品种、多生态区应用验证的系列进展。\n\n中国科学院院士钱前介绍，团队首次将蒲公英孤雌生殖基因ToPAR引入水稻，与减数分裂改造技术相结合，在部分水稻材料中实现了同一株系克隆率达100%、结实率达93.54%，兼顾了水稻的高效克隆与正常结实能力。在此基础上，团队以嘉丰优3号为背景创制的L3材料完成了连续五代跟踪验证，为优良杂交组合遗传组成的跨世代传递提供了重要依据。\n\n为检验该技术的适用范围，团队对中国、南亚和东南亚具有代表性的20个杂交稻组合开展了验证，涵盖三系籼型、三系籼粳型和两系籼型，均获得了相应的无融合生殖材料，其中18个组合的克隆率超过90%。\n\n今年，团队进一步在北京、合肥、长沙、杭州和三亚等地生物育种专区布局了全国多生态区正季田间试验，在覆盖从北方稻区、长江中下游稻区到华南热带稻区的不同生态环境下，团队布局无融合生殖材料，考察不同纬度、光温条件和稻作生态环境下的材料表现，推动技术评价从单一材料向多遗传背景、多生态区拓展。\n\n结果表明，人工无融合生殖正在从“单个材料能够实现克隆繁殖”，向“不同优良组合能够转化、不同生态区能够验证”的方向推进。未来有望将经过多年生产验证的成熟杂交品种直接转化为能连续繁殖的“一系法”材料，显著缩短技术进入产业的周期，提高成熟杂交品种向“一系法”升级的效率。\n\n此次观摩会现场，团队示范设置了单本、二本、三本等栽插方式，将分子育种与栽培调控相结合，探索改善群体稳定性的配套措施。在所展示的栽培条件下，相关材料表现出了良好的群体长势和农艺性状。\n\n崖州湾实验室主任、中国科学院院士李家洋称，固定杂种优势是杂交水稻育种的重要研究方向，当前研究进展展现出了其良好的应用潜力。但与此同时，阶段性成果距离真正大规模生产应用还有诸多现实难题亟待攻克。环境对无融合生殖性状的影响、不同遗传背景下表现的稳定性、长期多代繁育的可靠性、配套栽培技术体系等问题还需持续系统研究。他建议下一步持续深化基础机理研究，进一步做实多生态、多代跟踪验证，力争形成一套稳定、可重复、适合生产应用的技术体系。","内蒙古科协
