Integrated water-energy-food-environment (WEFE) planning is therefore needed to identify strategies that can reduce environmental burdens for a fixed wheat-production functional unit. This study develops a farm-scale WEFE nexus optimization model for 1 ha of wheat production and compares five scenarios: baseline, circular economy, decarbonization, water scarcity, and integrated sustainability. The model evaluates alternative water-supply, nutrient-recovery, and electricity-generation pathways using cost, life-cycle greenhouse gas emissions, circularity, and nexus performance indicators. Under the baseline compromise solution, total cost and greenhouse gas emissions were 549.67 USD ha −1 and 1537.72 kg CO₂-eq ha −1 , respectively, with a renewable-energy share of 60.46% and irrigation circularity of 12.73%. The integrated scenario achieved the strongest overall performance, reducing greenhouse gas emissions by about 49% to 784.79 kg CO₂-eq ha −1 , increasing fertilizer recovery to 40%, and raising the renewable-energy share to 92.70% under the fixed wheat-production requirement. These results show that coordinated water reuse, nutrient recovery, and electricity decarbonization provide greater sustainability gains than single-sector interventions. The study contributes a nexus-based optimization framework for evaluating circular and low-carbon agricultural transitions in water-stressed cereal production systems.","华北平原的集约化小麦生产对区域粮食安全至关重要，但也对地下水资源、化肥需求、能源利用和温室气体排放构成巨大压力。因此，需要开展水-能-粮-环境（WEFE）综合规划，以确定在固定小麦生产功能单位下能够降低环境负担的策略。本研究构建了一个针对1公顷小麦生产的农场尺度WEFE关联优化模型，并比较了五种情景：基准情景、循环经济情景、脱碳情景、水资源短缺情景和综合可持续情景。该模型采用成本、生命周期温室气体排放、循环性和关联性能指标来评估替代性供水、养分回收和发电路径。在基准折中方案下，总成本和温室气体排放分别为549.67美元\u002F公顷和1537.72千克CO₂当量\u002F公顷，可再生能源占比为60.46%，灌溉循环率为12.73%。综合情景实现了最佳整体表现，在固定小麦生产需求下，温室气体排放减少约49%至784.79千克CO₂当量\u002F公顷，肥料回收率提高至40%，可再生能源占比提升至92.70%。这些结果表明，协同推进水的回用、养分回收和电力脱碳比单一部门干预能带来更大的可持续性收益。本研究为评估缺水谷物生产系统中的循环和低碳农业转型提供了一个基于关联的优化框架。",null,"Frontiers in Sustainable Food Systems","2026-09-09T00:00:00Z","论文",10,false,79,{"impact":17,"substance":18,"depth":17,"authority":19,"freshness":20,"relevant":21,"comment":22},18,22,13,8,1,"华北平原小麦水-能-粮-环境耦合优化研究，量化了减碳49%、肥料回收40%等结论，方法新颖数据扎实，对缺水区小麦绿色生产有参考价值。",[24],{"name":10,"url":6},[26,27,28,29,30],"小麦","水肥一体化","循环农业","绿色低碳","华北平原",0,"10.3389\u002Ffsufs.2026.1897603",{"doi":32,"openalex_id":34,"authors":35,"venue":10,"cited_by_count":31,"oa_url":38,"card":39,"direction":43,"ingested_from":45},"W7212082572",[36],{"name":37,"orcid":9},"Gaodi Yang","https:\u002F\u002Fwww.frontiersin.org\u002Fjournals\u002Fsustainable-food-systems\u002Farticles\u002F10.3389\u002Ffsufs.2026.1897603\u002Fpdf",{"tldr":40,"method":41,"finding":42,"direction":43,"opportunity":44},"构建农场尺度水-能-粮-环境耦合优化模型，比较五种情景以优化华北平原小麦生产的可持续性。","农场尺度WEFE耦合优化模型，评估水、养分、电力路径，用成本、生命周期温室气体、","综合情景温室气体减排约49%，肥料回收率升至40%，可再生能源占比达92.7%，优于单部门干预。","农业绿色发展与碳","可将该WEFE耦合优化框架扩展到其他缺水作物系统，并耦合农户行为与政策激励进行情景分析。","openalex","2026-09-10T23:30:07.730098Z"]
