摘要
设施蔬菜碳排放核算已成为设施园艺领域节能降碳的研究重点。目前已有较多国外学者应用生命周期评价(LCA)在设施蔬菜领域进行研究,然而国内相关研究起步较晚。本文通过梳理该领域内近20年的国内外研究成果,选取53篇涵盖不同地区设施蔬菜生产的文献进行深入分析。在进一步对其功能单位、系统边界和环境影响评价分析的过程中,比较大宗农资产品碳排放因子和单位农产品生产的碳排放量差异,指出碳核算存在的主要问题。最后提出设施蔬菜LCA的技术框架,即从摇篮到消费者的全环节,总结了节能减排的主要方式。本综述可为后续设施蔬菜碳核算及其对环境影响的定量评估和综合技术寻优提供支持。
Carbon emission accounting for greenhouse vegetable production has become the research priority.At present,many foreign scholars have applied life cycle assessment(LCA)to conduct research in the field of greenhouse vegetable production.However,domestic research started relatively late and few relevant studies in recent years.This paper reviews the research progress both domestically and internationally over the past two decades,selecting 53 relevant articles covering greenhouse vegetable production in various regions for in-depth analysis.In the process of further analyzing its functional unit,system boundary and environmental impact assessment,the differences between the carbon emission factors of bulk agricultural materials and carbon emissions per unit of agricultural product production were compared,and the main problems existing in carbon accounting were pointed out.Finally,the paper proposes a technical framework in greenhouse vegetable production,namely the entire process from cradle to consumer,and summarizes key strategies for energy conservation and emission reduction.This review aims to support future carbon accounting efforts,environmental impact assessments of greenhouse vegetable production,andcomprehensive optimization of related technologies.
