Standard multi-class classifiers optimize global accuracy but provide no mechanism to operationalize or control this asymmetric cost structure at inference time. We propose CascadeCropNet, a two-stage cascade architecture calibrated to satisfy a target recall constraint (Rec-Damaged >= 0.95) through threshold selection. A lightweight Sentinel model performs binary health triage; samples exceeding a calibrated damage probability threshold tau are escalated to a specialist Expert model for fine-grained diagnosis. This design provides explicit, deployment-time control over the safety-efficiency trade-off without retraining. Evaluated on the Eyes on the Ground dataset (23,804 images from Kenyan smallholder maize farms), the cascade achieves Rec-Damaged = 0.974 at tau = 0.5, reducing missed damage cases by up to 54% relative to a flat baseline. Under evaluation alignment, the representational gap reduces to +0.008 F1-macro, confirming the contribution is architectural rather than representational. Under input degradation, the system prioritizes escalation over confident misclassification, reflecting error containment through architectural isolation rather than intrinsic model robustness. These results demonstrate that cascade architectures can operationalize safety-oriented decision constraints through calibrated routing in settings where reliability matters more than aggregate accuracy. These properties depend on threshold calibration and deployment conditions and do not constitute guarantees under arbitrary distribution shift.\n\nComments:44 pages, 7 figures, 12 tables.

This exploratory qualitative study examined smallholder farmers’ lived experiences of FAW damage in hybrid and local maize in Siaya County, Kenya. Face-to-face semi-structured interviews lasting 30–45 min were conducted with 88 purposively selected farmers, and responses were analyzed thematically by two independent researchers. Farmers described FAW as recurrent and difficult to control; 43.2% reported infestation every season. Most participants (77.3%) perceived hybrid maize as more severely affected than local maize, whereas 9.1% perceived local maize as more affected and 9.1% reported similar effects. Participants associated infestation with reduced yields, impaired crop growth, lower-quality harvests, lost income, pesticide and labour costs, depleted maize stocks, food purchases, and stress related to financial and food uncertainty. Reported responses included pesticide use, repeated spraying, purchasing food, crop diversification, and reconsidering maize varieties. Because the study relied on farmers’ accounts rather than controlled varietal comparisons, the perceived differences cannot be attributed to seed characteristics independently of management and growing conditions. The findings indicate that farmers evaluate FAW damage through interconnected production, livelihood, food-security, and seed-choice concerns, supporting locally tested pest-management and seed advisory services.","草地贪夜蛾（Fall Armyworm, FAW）是撒哈拉以南非洲以玉米为基础的粮食系统面临的持续威胁，但人们对农民在不同种子类型和家庭生计条件下如何经历其影响知之甚少。本探索性定性研究考察了肯尼亚西亚亚县小农户在杂交玉米和本地玉米中遭受草地贪夜蛾危害的生活体验。研究对88名有意选取的农民进行了为期30至45分钟的面对面半结构化访谈，并由两名独立研究人员对回答进行主题分析。农民将草地贪夜蛾描述为反复发生且难以控制；43.2%报告每季均发生虫害。大多数参与者（77.3%）认为杂交玉米比本地玉米受害更严重，而9.1%认为本地玉米受害更严重，9.1%报告两者影响相似。参与者将虫害与产量下降、作物生长受损、收成品质量降低、收入损失、农药和劳动力成本、玉米库存耗尽、粮食购买以及与经济和粮食不确定性相关的压力联系起来。报告的应对措施包括使用农药、反复喷药、购买粮食、作物多样化以及重新考虑玉米品种。由于本研究依赖农民叙述而非受控品种比较，所感知的差异不能独立于管理和生长条件而归因于种子特征。研究结果表明，农民通过生产、生计、粮食安全和种子选择等相互关联的关注来评估草地贪夜蛾危害，这支持开展本地化测试的害虫管理和种子咨询服务。","Frontiers in Sustainable Food Systems","2026-10-02T00:00:00Z",65,{"impact":87,"substance":17,"depth":88,"authority":19,"freshness":13,"relevant":21,"comment":89},8,16,"基于88户肯尼亚小农户访谈的质性研究，揭示草地贪夜蛾对杂交与本地玉米影响的农户感知差异，对非洲玉米病虫害防控与种子推广有参考价值，但属区域案例、公共影响有限。",[91],{"name":83,"url":80},[93,94,36,60,95],"种业振兴","粮食安全","病虫害防治",{"code":34,"slug":35,"name":36,"path":37,"parent_code":38},[98],{"code":41,"slug":42,"name":43,"path":44,"parent_code":45},{"status":47,"locked":14,"version":48,"method":49,"evidence":100},{"candidates":101,"agricultural_evidence":54},[102,107,112,119,124],{"code":34,"score":103,"supported":54,"title":104,"abstract":105,"tags":106},15,[35],[36,35],[36],{"code":41,"score":103,"supported":54,"title":108,"abstract":110,"tags":111},[109],"smallholder",[60,109],[60],{"code":113,"score":75,"supported":54,"title":114,"abstract":115,"tags":118},"F4",[],[116,117],"农药","pesticide",[],{"code":120,"score":65,"supported":54,"title":121,"abstract":122,"tags":123},"A8",[],[94],[94],{"code":125,"score":21,"supported":14,"title":126,"abstract":127,"tags":128},"F1",[],[],[93],[130,131],"肯尼亚 草地贪夜蛾 玉米","杂交玉米 本地玉米 虫害","肯尼亚草地贪夜蛾玉米-3989",3,"10.3389\u002Ffsufs.2026.1925312",{"doi":134,"openalex_id":136,"authors":137,"venue":83,"cited_by_count":148,"oa_url":80,"card":149,"direction":153,"ingested_from":155},"W7215042180",[138,141,143,145],{"name":139,"orcid":140},"George Ariya","https:\u002F\u002Forcid.org\u002F0000-0003-2286-9455",{"name":142,"orcid":8},"Beatrice Cheserek",{"name":144,"orcid":8},"Violet Kadenyeka Mugalavai",{"name":146,"orcid":147},"Lizzy A.

However, its distributional effects across farm households remain underexplored. Drawing on Sen’s capability approach, this study investigates the impact of agricultural insurance coverage on income inequality among farm households. Methods Using a two-wave panel dataset of 627 corn-growing households in Liaoning Province, China, from 2021 to 2022, we employ a two-way fixed effects model to estimate the effect of agricultural insurance coverage on farm household income inequality. We further test the robustness of the baseline results through a series of checks, including replacing the dependent variable, controlling for village-level fixed effects, adding village-level controls, clustering bootstrap standard errors at the village level and alternative model specifications. Exploratory analysis and heterogeneity analysis are also conducted. Results The empirical results yield four main findings. First, higher agricultural insurance coverage is positively associated with income inequality among farm households, and this pattern remains robust across multiple tests. Second, the observed association with inequality is concentrated in operating income, with no significant corresponding patterns for wage income, property income, or transfer income. Third, exploratory analysis suggests that agricultural insurance coverage is linked to greater land transfer-in primarily for high-income households, a relationship that is consistent with the observed increased income inequality. Fourth, this association is more pronounced among households with greater realized production loss and among those living in areas without income insurance policies. Discussion This study enriches the literature on agricultural insurance by highlighting its unintended distributional consequences. Although agricultural insurance plays an important role in risk management, its potential to widen inequality implies that policy design should not rely on insurance alone. Greater attention to equity requires complementary redistributive instruments, alongside efforts to make insurance more inclusive for disadvantaged farmers.","引言 随着气候变率和生产不确定性日益威胁农业生计，农业保险已成为气候风险管理和稳定农户收入的重要工具。然而，其对不同农户的分配效应仍缺乏充分探讨。本研究基于森的可行能力方法，考察农业保险覆盖对农户收入不平等的影响。方法 使用2021年至2022年中国辽宁省627个玉米种植户的两期面板数据，采用双向固定效应模型估计农业保险覆盖对农户收入不平等的影响。我们进一步通过一系列检验验证基准结果的稳健性，包括替换因变量、控制村级固定效应、加入村级控制变量、在村级聚类自助法标准误以及替代模型设定。同时进行了探索性分析和异质性分析。结果 实证结果得出四个主要发现。第一，较高的农业保险覆盖与农户收入不平等呈正相关，且这一模式在多项检验中保持稳健。第二，观察到的与不平等的关系集中于经营收入，而工资性收入、财产性收入或转移性收入未呈现显著的相应模式。第三，探索性分析表明，农业保险覆盖与高收入农户更多转入土地相关，这一关系与观察到的收入不平等加剧相一致。第四，这种关联在实际生产损失较大的农户以及居住在无收入保险政策地区的农户中更为明显。讨论 本研究通过揭示农业保险的非预期分配后果，丰富了农业保险文献。尽管农业保险在风险管理中发挥重要作用，但其扩大不平等的潜力意味着政策设计不应仅依赖保险。更加关注公平需要 complementary 再分配工具，同时努力使保险对弱势农户更具包容性。","2026-09-10T00:00:00Z",77,{"impact":88,"substance":18,"depth":17,"authority":19,"freshness":87,"relevant":21,"comment":242},"基于辽宁627户玉米种植户两期面板数据的实证研究，揭示农业保险覆盖扩大反而加剧农户收入不平等，并指出其通过高收入户土地转入的传导机制，对农业保险政策设计具有重要警示价值。",[244],{"name":83,"url":236},[30,246,247,248,249],"收入不平等","玉米种植","农户收入","土地流转",{"code":34,"slug":35,"name":36,"path":37,"parent_code":38},[252],{"code":64,"slug":253,"name":254,"path":255,"parent_code":45},"rural-finance","农村金融与保险","\u002Ftopic\u002Frural-services\u002Frural-finance",{"status":47,"locked":14,"version":48,"method":49,"evidence":257},{"candidates":258,"agricultural_evidence":54},[259,264,269,274],{"code":34,"score":103,"supported":54,"title":260,"abstract":262,"tags":263},[261],"corn",[36,261],[247],{"code":64,"score":103,"supported":54,"title":265,"abstract":267,"tags":268},[266],"agricultural insurance",[30,266],[30],{"code":41,"score":65,"supported":54,"title":270,"abstract":271,"tags":273},[],[272],"land transfer",[249],{"code":275,"score":65,"supported":54,"title":276,"abstract":277,"tags":278},"G6",[],[248],[248],[280,281],"收入不平等 农业保险 农户收入 土地流转","收入不平等 农业保险","收入不平等农业保险农户收入土地流转-2128","10.3389\u002Ffsufs.2026.1856386",{"doi":283,"openalex_id":285,"authors":286,"venue":83,"cited_by_count":148,"oa_url":236,"card":301,"direction":153,"ingested_from":155},"W7212115989",[287,290,293,296,298],{"name":288,"orcid":289},"Bo Hu","https:\u002F\u002Forcid.org\u002F0000-0001-8527-3750",{"name":291,"orcid":292},"Wenbo Zhang","https:\u002F\u002Forcid.org\u002F0000-0003-4672-1420",{"name":294,"orcid":295},"Chunli Wan","https:\u002F\u002Forcid.org\u002F0000-0002-6027-4869",{"name":297,"orcid":8},"Naihe Jiang",{"name":299,"orcid":300},"Fengjie Xie","https:\u002F\u002Forcid.org\u002F0000-0003-0688-3126",{"tldr":302,"method":303,"finding":304,"direction":153,"opportunity":305},"基于辽宁玉米户面板数据，发现农业保险覆盖扩大反而加剧农户收入不平等。","2021-2022年627户两期面板数据，双向固定效应模型及多种稳健性检验。","保险覆盖与收入不平等正相关，主要来自经营收入，高收入户土地转入更多。","可研究保险与数字信贷、补贴等政策组合对农户收入分配公平性的协同调节机制。","2026-09-11T23:30:07.758358Z",{"id":308,"title":309,"url":310,"summary":311,"summary_zh":312,"content":8,"source_name":313,"source_url":310,"published_at":314,"category":12,"cover_url":8,"hotness":13,"is_selected":14,"score":315,"score_detail":316,"sources":319,"tags":321,"primary_topic":326,"secondary_topics":327,"classification":334,"search_phrases":351,"slug":354,"view_count":148,"doi":355,"paper":356,"created_at":371},5592,"Evaluation of Concept-Rank Collapse Audits for Computer Vision Agriculture Disease Classifiers Under Low-Label Regimes: An Interpretability Capacity Bound for Smallholder Fungicide Selectivity","https:\u002F\u002Fdoi.org\u002F10.5281\u002Fzenodo.23545193","Concept-based interpretability methods for plant-disease classifiers are typically evaluated by whether their concept activations correlate with human-annotated labels, but this criterion is silent on a prior question: whether the classifier's internal representation retains enough concept-rank structure for any audit to be informative. the present analysis formalises that prior question as an interpretability capacity bound. A classifier is modelled as a concept-rank operator whose singular values govern how much concept-level signal survives the projection from pixel space to class logits, and a collapse audit is defined as the ratio of retained concept-rank energy to total concept energy. Under a low-label regime, where concept annotations are scarce and the audit must be estimated from few labelled examples, the bound predicts that audit reliability degrades as a function of the concept-rank spectrum and the label budget. The analysis is a theoretical and methodological contribution: it derives the bound, states the conditions under which a collapse audit is identifiable, and characterises the operating characteristics of the audit as a decision procedure under a declared variance structure (between-cluster SD = 6.0, residual SD = 4.5, intraclass correlation = 0.64). Power was estimated across 2000 design cells for cluster counts of 8, 16, 24 and 32 and effect sizes of 3, 5 and 8 percentage points; 52 clusters were required for 5 percentage points at 80% power. The bound reframes concept audits as capacity tests rather than fidelity tests, with consequences for how smallholder fungicide-selectivity decisions should be supported by interpretable disease classifiers.","面向植物病害分类器的基于概念的可解释性方法，通常以其概念激活是否与人工标注标签相关作为评价标准，但该标准对一个更先前的问题保持沉默：分类器的内部表征是否保留了足够的概念秩结构，从而使任何审计具有信息量。本分析将该先前问题形式化为一个可解释性容量上界。分类器被建模为概念秩算子，其奇异值支配着从像素空间到类别logits的投影中概念级信号得以保留的程度，并将坍缩审计定义为保留的概念秩能量与总概念能量之比。在低标签情形下，概念标注稀缺且审计必须由少量标注样本估计，该上界预测审计可靠性会随概念秩谱和标签预算的函数而退化。本分析是一项理论和方法论贡献：推导出该上界，陈述坍缩审计可识别的条件，并在声明的方差结构（簇间SD = 6.0，残差SD = 4.5，组内相关系数 = 0.64）下刻画审计作为决策程序的操作特征。在2000个设计单元中，针对簇数为8、16、24和32以及效应量为3、5和8个百分点的情形估计了功效；在80%功效下达到5个百分点需要52个簇。该上界将概念审计重新框定为容量检验而非保真度检验，并对可解释病害分类器应如何支持小农杀菌剂选择性决策具有启示意义。","Zenodo (CERN European Organization for Nuclear Research)","2026-10-21T00:00:00Z",69,{"impact":87,"substance":317,"depth":17,"authority":166,"freshness":13,"relevant":21,"comment":318},21,"理论方法论文，提出可解释性容量上界并给出审计功效分析，对智慧农业病害识别可信度有参考价值，但属小众方法学研究、缺乏田间实证，暂不宜进入每日精选。",[320],{"name":313,"url":310},[322,323,60,324,325],"智慧农业","农业人工智能","植物病害识别","可解释性",{"code":41,"slug":42,"name":43,"path":44,"parent_code":45},[328],{"code":329,"slug":330,"name":331,"path":332,"parent_code":333},"I2","agricultural-ai","农业AI与大模型","\u002Ftopic\u002Fdigital-agriculture\u002Fagricultural-ai","I",{"status":47,"locked":14,"version":48,"method":49,"evidence":335},{"candidates":336,"agricultural_evidence":54},[337,341,346],{"code":41,"score":166,"supported":54,"title":338,"abstract":339,"tags":340},[109],[109],[60],{"code":329,"score":13,"supported":54,"title":342,"abstract":344,"tags":345},[343],"computer vision",[],[323,324],{"code":347,"score":21,"supported":14,"title":348,"abstract":349,"tags":350},"I1",[],[],[322],[352,353],"农业人工智能 植物病害识别 可解释性 智慧农业","农业人工智能 植物病害识别","农业人工智能植物病害识别可解释性智慧农业-5592","10.5281\u002Fzenodo.23545193",{"doi":355,"openalex_id":357,"authors":358,"venue":313,"cited_by_count":148,"oa_url":310,"card":365,"direction":369,"ingested_from":155},"W7223137323",[359,361,363],{"name":360,"orcid":8},"Akshay Ramgoolam",{"name":362,"orcid":8},"Priya Bundhoo Appadoo",{"name":364,"orcid":8},"Jean-Noël LEspérance",{"tldr":366,"method":367,"finding":368,"direction":369,"opportunity":370},"提出可解释性容量上界，评估低标签下概念秩崩溃审计的可靠性。","将分类器建模为概念秩算子，推导容量上界并做2000格功效模拟。","审计可靠性随概念秩谱与标签预算下降；5个百分点效应需52个聚类达80%功效。","农业人工智能与决策模型","可将容量上界用于小农户杀菌剂选择性决策的可解释模型审计与标签预算设计。","2026-10-22T11:21:10.425290Z",{"id":373,"title":374,"url":375,"summary":376,"summary_zh":377,"content":8,"source_name":313,"source_url":375,"published_at":314,"category":12,"cover_url":8,"hotness":13,"is_selected":14,"score":378,"score_detail":379,"sources":381,"tags":383,"primary_topic":386,"secondary_topics":387,"classification":389,"search_phrases":404,"slug":407,"view_count":148,"doi":408,"paper":409,"created_at":423},5590,"Evaluation of Concept-Probe Temporal-Stability Audits for Computer Vision Agriculture Disease Classifiers Under Seasonal Phenology Drift: An Interpretability Decay Bound for Smallholder Fungicide Timing","https:\u002F\u002Fdoi.org\u002F10.5281\u002Fzenodo.23545234","Concept-probe audits are increasingly used to certify that a crop-disease classifier's internal representations track the pathological concepts a smallholder would act on, but a probe certified at one point in the season may silently decouple from those concepts as phenology shifts the visual statistics of the field. the present analysis treats that decoupling as a formal object. It defines a temporal-stability audit as a sequence of concept-probe accuracies measured across defined phenological windows, and it derives an interpretability decay bound: the rate at which probe accuracy can fall before the fungicide-timing decision it is meant to support becomes unreliable. The bound is expressed as a function of the probe's initial margin, the drift in concept prevalence between windows, and the classifier's sensitivity to the drifted features, and it yields a certified audit interval rather than a single-point certificate. The paper then characterises the operating characteristics of the audit design under a declared variance structure, using a replication-based evaluation of the before-after-control-impact estimator with between-cluster SD = 6.0, residual SD = 4.5 and intraclass correlation = 0.64.

Agroecology offers a promising pathway to enhance resilience and support inclusive rural development. In this context, Tunisia’s olive sector provides a relevant case for examining agroecological transitions in semi-arid smallholder systems. This study evaluates the degree of agroecological transition among smallholder olive farms in the Elles region of northwestern Tunisia using the FAO Tool for Agroecology Performance Evaluation (TAPE). Based on a sample of 60 farms, the analysis applies the Characterization of Agroecological Transition (CAET) index, grounded in the 10 Elements of Agroecology, to compare four production systems: (i) olive monoculture, (ii) diversified cropping, (iii) olive–livestock integration, and (iv) integrated olive–crop–livestock systems. Economic, social, environmental and institutional performance were explored using the TAPE Core Criteria of Performance (Step 2) and examined in relation to CAET scores. Results reveal a clear agroecological gradient, with diversified and integrated systems achieving markedly higher CAET scores (up to 52%) compared to monoculture systems (31%). Spearman correlations show strong associations between CAET and key dimensions, including synergy (ρ = 0.79), human and social values (ρ = 0.78), and diversity (ρ = 0.71). Several TAPE economic performance indicators, including monthly income, which ranged from approximately 1,349 TND in monoculture systems to 4,892 TND in diversified olive–crop–livestock systems, were positively associated with higher CAET scores, suggesting that agroecological transition may not necessarily imply a trade-off between productivity and sustainability. However, limited collective action, weak market integration, and insufficient extension services constrain broader adoption. These findings highlight the potential of diversification as a key lever for agroecological transition and underscore the importance of targeted policy support.","农业集约化提高了产量并促进了经济增长，但也产生了威胁长期可持续性的重大环境与社会挑战，凸显了对更可持续耕作模式的需求。农业生态学为增强韧性和支持包容性农村发展提供了一条有前景的路径。在此背景下，突尼斯橄榄产业为研究半干旱小农系统中的农业生态转型提供了相关案例。本研究利用联合国粮农组织农业生态性能评价工具（TAPE），评估突尼斯西北部埃勒斯地区小农橄榄农场的农业生态转型程度。基于60个农场的样本，分析采用以农业生态学十大要素为基础的农业生态转型特征（CAET）指数，比较四种生产系统：（i）橄榄单作，（ii）多样化种植，（iii）橄榄—畜牧结合，以及（iv）橄榄—作物—畜牧综合系统。研究利用TAPE核心性能标准（第二步）探讨经济、社会、环境和制度绩效，并将其与CAET得分进行关联分析。结果揭示了明显的农业生态梯度，多样化与综合系统的CAET得分（最高达52%）显著高于单作系统（31%）。斯皮尔曼相关性分析显示，CAET与关键维度之间存在强关联，包括协同性（ρ = 0.79）、人文与社会价值（ρ = 0.78）和多样性（ρ = 0.71）。若干TAPE经济绩效指标——包括月收入，其从单作系统的约1，349突尼斯第纳尔到橄榄—作物—畜牧多样化系统的4，892突尼斯第纳尔不等——与更高的CAET得分呈正相关，表明农业生态转型未必意味着生产力与可持续性之间的权衡。然而，集体行动有限、市场整合薄弱和推广服务不足制约了更广泛的采纳。这些发现凸显了多样化作为农业生态转型关键杠杆的潜力，并强调了有针对性的政策支持的重要性。",71,{"impact":166,"substance":165,"depth":432,"authority":19,"freshness":20,"relevant":21,"comment":433},17,"基于FAO TAPE方法对突尼斯小农户橄榄系统农生态转型的实证研究，数据扎实、结论有新意，但属区域性案例，公共影响有限。",[435],{"name":83,"url":427},[60,437,438,439,440],"农业转型","生态农业","突尼斯","油橄榄",{"code":41,"slug":42,"name":43,"path":44,"parent_code":45},[],{"status":47,"locked":14,"version":48,"method":49,"evidence":444},{"candidates":445,"agricultural_evidence":54},[446,450,457,463,470,476],{"code":41,"score":166,"supported":54,"title":447,"abstract":448,"tags":449},[109],[109],[60],{"code":451,"score":75,"supported":54,"title":452,"abstract":453,"tags":456},"C",[],[454,455],"畜牧","livestock",[],{"code":45,"score":75,"supported":54,"title":458,"abstract":459,"tags":462},[],[460,461],"农村发展","rural development",[],{"code":464,"score":75,"supported":54,"title":465,"abstract":466,"tags":469},"H6",[],[467,468],"农业生态","agroecology",[],{"code":471,"score":133,"supported":54,"title":472,"abstract":473,"tags":475},"H7",[],[474],"干旱",[],{"code":477,"score":21,"supported":14,"title":478,"abstract":479,"tags":480},"H8",[],[],[438],[482,483],"突尼斯 油橄榄 小农户","TAPE 农生态 评估","突尼斯油橄榄小农户-5548","10.3389\u002Ffsufs.2026.1903591",{"doi":485,"openalex_id":487,"authors":488,"venue":83,"cited_by_count":148,"oa_url":427,"card":509,"direction":513,"ingested_from":155},"W7223108121",[489,491,493,496,499,501,504,507],{"name":490,"orcid":8},"Rihab Mejri",{"name":492,"orcid":8},"Meriem Oueslati Zlaoui",{"name":494,"orcid":495},"Inès Gharbi","https:\u002F\u002Forcid.org\u002F0000-0003-2558-2134",{"name":497,"orcid":498},"Asma Souissi","https:\u002F\u002Forcid.org\u002F0000-0002-8680-5875",{"name":500,"orcid":8},"Ghada Ferchichi",{"name":502,"orcid":503},"Rania Soula","https:\u002F\u002Forcid.org\u002F0000-0002-6086-9176",{"name":505,"orcid":506},"Boubaker Dhehibi","https:\u002F\u002Forcid.org\u002F0000-0003-3854-6669",{"name":508,"orcid":8},"Mohamed Zied Dhraief",{"tldr":510,"method":511,"finding":512,"direction":513,"opportunity":514},"用FAO TAPE工具评估突尼斯西北小农橄榄农场生态农业转型程度。","FAO TAPE框架与CAET指数，调查60个农场比较四类种植系统。","多样化与综合系统CAET得分达52%，单作仅31%，且收入更高。","农业绿色发展与碳","可将TAPE与CAET指标数字化，构建小农生态转型监测与决策支持系统。","2026-10-22T11:20:15.716064Z"]
