全球经济持续发展与环境变化的双重背景下，粮食生产与消费过程对环境的影响愈发显著，特别是粮食生命周期中温室气体排放问题，已成为气候变化和生态平衡的一项重要挑战。综合分析国际和国内粮食生命周期碳排放研究进展可揭示该领域研究趋势和前沿热点。本研究通过检索Web of Science(WoS)和中国知网(CNKI)数据库的中英文文献，运用科学知识图谱以及CiteSpace文献可视化工具进行深入分析和可视化呈现。结果表明:2003 年国际上开始出现粮食生命周期碳排放相关研究，国内于 2009 年开始关注此问题，两者均呈稳步增长态势;国际和国内研究侧重点不同，国际研究包括粮食生产与消费、整个粮食系统及供应链的综合研究，注重粮食系统及供应链的碳排放管理;国内研究侧重于粮食生产端、区域差异研究。未来国内粮食生命周期碳排放相关研究应更注重粮食生产与消费平衡，外卖服务等新兴行业需引发关注。粮食生命周期碳排放的区域差异对区域粮食可持续生产和消费的发展至关重要。混合生命周期评估将成为主流研究方法，全面评估粮食生命周期碳排放的多个方面。政策效果也将成为重要的研究焦点，以推动粮食生命周期碳减排。
Current Status and Development Trend of Food Life-cycle Carbon Emissions Research
The impact of food production and consumption processes on the environment has become increasingly apparent in the context of ongoing economic development and the environment.Especifically,the issue of greenhouse gas emissions in the life cycle of food has emerged as a major challenge in the realm of climate change and ecological balance.A comprehensive analysis of international and domestic research progress on food life cycle carbon emissions can reveal the research trends and frontier hotspots in this area.By conducting searches in English and Chinese literature databases,including the Web of Science(WoS)and China National Knowledge Infrastructure(CNKI),utilizing the scientific knowledge graph and the CiteSpace literature visualization tool,an in-depth analysis and visual representation were carried out.The results showed that research on carbon emissions from food lifecycle began to emerge internationally in 2003,while domestic attention to the issue began in 2009,and both had exhibited steady growth in their respective research activities.While Chinese research had largely emphasized the food production aspect,international research had taken a more holistic approach,encompassing research on both food production and consumption,the entire food system,and the supply chains.In addition,there was a greater emphasis internationally on the management of carbon emissions within food systems and supply chains,whereas Chinese research was more skewed towards the study of regional disparities.In the future,research on carbon emissions in the food lifecycle was likely to place increased emphasis on the equilibrium between food production and consumption,with emerging industries like food delivery services gaining attention.Regional disparities in food lifecycles'carbon emissions were crucial for the sustainable development of regional food production and consumption.Hybrid life cycle assessment was poised to become a mainstream research method,with future research comprehensively evaluating multiple aspects of food life cycle carbon emissions.The effectiveness of policies is also set to be a key focus of future research aimed at driving carbon reduction in the food life cycle.
