中国农业碳效应研究的现状、热点与趋势

Research on Status,Focus,and Developing Trend of Agricultural Carbon Effect in China

探究中国农业碳效应研究的现状、热点与趋势,可以为后续研究者提供参考,有助于提高该研究领域的广度与深度。以2009—2021年中国知网收录的708篇高水平期刊论文为基础数据,使用CiteSpace软件对作者、机构和关键词等信息进行可视化分析。结果表明:①研究现状方面,年发文量经历快速增长和稳定发展2个阶段,发文作者呈现“大体分散、局部集中”状态,大部分发文机构独立开展研究;②研究热点方面,发现了农业碳排放、碳排放、低碳农业、温室气体、农田生态系统和碳汇等核心关键词,识别出农业碳排放、土壤固碳、碳足迹、低碳农业、农业碳排放效率和碳减排6个聚类,找到了土壤固碳、土壤有机碳、低碳农业、温室气体减排、低碳经济、固碳减排、温室气体、对策、碳汇、lmdi模型、固碳速率和农业碳排放效率12个突现词,当前研究热点可以归纳为农业碳源/碳汇研究、农业固碳研究、农业碳减排研究、农业碳足迹研究和低碳农业研究五大类;③研究趋势方面,初现关键词集中在2009—2014年出现,农业碳效应研究呈现研究热度阶梯式上升、研究主题断崖式减少和研究方法逐渐多样化等趋势。最后,从中小区域、综合视角、全产业链、农户行为和粮食安全5个方面对未来研究方向进行展望。

Examining the research status, focus, and developing trend of the agricultural carbon effect in China can provide references to researchers and improve the breadth and depth of research on the agricultural carbon effect. In this study, 708 high-quality papers published from 2009 to 2021 in the Chinese Academic Journal Network Publishing Database were retrieved as basic data. CiteSpace software was used for a visualized analysis of information, including authors, institutions, and keywords. The results suggested that, in terms of research status, the number of papers experienced a high-speed growth period and a stable growth period;With their authors being mostly scattered and only some being concentrated. Most institutions conduct their research independently. In terms of research focus, the core words found throughout the existing research were agricultural carbon emissions, carbon emissions, low-carbon agriculture, greenhouse gas, farmland ecosystem, and carbon sink. Six clusters were identified, namely agricultural carbon emissions, soil carbon sequestration, carbon footprint, low-carbon agriculture, agricultural carbon emissions efficiency, and carbon emissions reduction.Additionally, 12 burst terms were observed, namely soil carbon sequestration, soil organic carbon, low-carbon agriculture, greenhouse gas emissions reduction, low carbon economy, carbon sequestration and emissions reduction, greenhouse gas, countermeasures, carbon sink, lmdi model, carbon sequestration rate, and agricultural carbon emissions efficiency. Five categories of research focus were summarized, namely agricultural carbon source/sink, agricultural carbon sequestration, agricultural carbon emissions reduction, agricultural carbon footprint, and low-carbon agriculture. In terms of research trends, the keywords were concentrated in papers published from 2009 to 2014. Research on the agricultural carbon effect shows trends of increasing research popularity, decreasing research topics, and increasing research methods. Finally, the prospect of the agricultural carbon effect in China was based on five aspects: mid-small areas, comprehensive perspective, the entire industry chain, farmer behavior, and grain security.
