摘要
稻田减排降碳是实现农业碳中和的重要研究领域,全面梳理水稻碳足迹研究脉络和领域发展前沿,为未来相关研究提供参考借鉴。采用文献计量学方法,在综合分析近30多年来(1990-2023年)水稻碳足迹研究相关文献基础上,对该领域研究历程、聚焦主题及发展趋势进行梳理探讨。结果表明:稻田碳足迹研究受到领域学者的广泛关注,2009年后文献数量快速增长,近10年来发文量贡献率达89.2%。领域形成明显的核心研究力量,中国、美国和印度是主要的文献发表国家,发文量占全球总量的75.9%;该研究领域发文量排名前10研究机构中有6个机构来中国,中国科学院发文量位居首位。关键词共现热点分析表明,水稻碳足迹研究呈现跨学科发展趋势,在稻田碳排放数量及过程、土壤碳固持速率及潜力、不同管理措施的固碳减排效果等方面取得较大进展,稻田碳固持、碳排放的微生物机制和水稻生产的生态、经济、资源利用等效益综合评价是该领域的研究热点。未来应逐步建立科学合理、标准统一的碳足迹评价方法体系,重点关注农户生产尺度稻田碳足迹定量评估,加强基于碳足迹研究情景分析的实证研究,为降低稻田碳足迹、实现水稻低碳绿色发展提供支撑。
Reducing carbon emission of rice field is an important research area for achieving carbon neutrality in agriculture.Comprehensively reviewing the history and frontier of this field could provide guideline for related research in the future.In this paper,based on a detailed analysis of literature related to carbon footprint research of rice field over the past 30 years(1990-2023)and using bibliometric methods,we explored the research process,focus themes,and development trends in this field.The results indicated that carbon footprint in rice fields had received widespread attention from scientists in the area.The number of literatures grew rapidly since 2009,and the contribution rate of published literature in the past ten years had reached 89.2%.A clear core research forces had been observed in the area.China,the United States,and India were the main countries for publishing literatures,which accounting for 75.9%of the total world publications.Ranking of the numbers of publication showed that six of the top ten research institutions were from China,and the Chinese Academy of Sciences ranked first.The analysis of keywords co-occurrence hotspots indicated that the research on carbon footprint of rice field showed an interdisciplinary development trend.Significant progress had been made in the quantity and process of carbon emissions from rice fields,the rate and potential of soil carbon sequestration,and the effects on carbon sequestration and emission reduction of different management measures.The microbial mechanisms of carbon sequestration and carbon emissions in rice fields,as well as the comprehensive evaluation of the ecological,economic and resource utilization benefits of rice production,were the hotspots in this research area.In the future,a scientific,reasonable and standardized carbon footprint evaluation method system should be gradually established.It was necessary to focus on the quantitative assessment of carbon footprint in rice fields at the production scale of farmers.The evidence-based validation
