农业碳排放研究进展及热点可视化分析——基于CNKI和WOS数据库

为明确当前农业碳排放发展现状和研究前沿，整理并筛选了2010—2023年CNKI数据库和Ｗeb of Science核心合集收录的农业碳排放相关文献，并应用 CiteSpace和VOSviewer分析软件对农业碳排放相关文献进行对比分析与可视化呈现。结果表明：1）2010—2023年，国内该领域发文量呈上升趋势，2016年后发文量显著增加；虽然中国作者发表文献量少于国外作者，但近年来发展迅速，国际影响力逐步提高。2）中国农业碳排放研究已经形成相对稳定的团队，分别在农业经济关系、协同减排方式、生物炭等领域开展了大量研究，但中国与其他国家研究团队联系相对较少，仍需要进一步加强。3）国内外发文最多机构均为中国高校，中国科学院、中国农业大学与华中农业大学对中国农业碳排放发展做出积极贡献。4）中国被引次数最高的文献是《中国农业碳排放时空特征及影响因素分解》，国际共被引最多的文献是Greenhouse gas mitigation in agriculture。5）农业碳排放测算、农业碳减排相关方法与政策研究依然是当今热门研究方向，除此之外，经济发展与农业碳排放相互关系研究逐渐成为当前热点。

Advances in agricultural carbon emission research and visualization analysis of hotspots：Based on the CNKI and WOS databases

To clarify the current status and frontier of agricultural carbon emissions research， this study systematically reviewed and selected relevant literature from the CNKI database and Web of Science core collection from 2010 to 2023. By using CiteSpace and VOSviewer software， comparative analysis and visualization of agricultural carbon emissions literature were conducted. The results indicate： 1） From 2010 to 2023， the number of publications in this field in China has been on the rise， with a significant increase after 2016. Although the quantity of Chinese publications is less than that of foreign scholars， Chinese researchers have shown rapid development and a gradual increase in international influence. 2） China’s research on agricultural carbon emissions has formed a relatively stable team， conducting extensive research in areas such as agricultural economic relations， collaborative emission reduction methods， and biochar. However， there is relatively limited collaboration between Chinese research teams and those of other countries， indicating the need for further strengthening. 3） The most prolific institutions in terms of domestic and international publications are Chinese universities， with the Chinese Academy of Sciences， China Agricultural University， and Huazhong Agricultural University making significant contributions to the development of China’s agricultural carbon emissions. 4） The most highly cited document in China is ‘Research on spatial-temporal characteristics and affecting factors decomposition of agricultural carbon emission in China’， while the most internationally cited document is Greenhouse gas mitigation in agriculture； 5） Carbon calculation of agricultural emissions， research on methods and policies related to agricultural carbon reduction， remain popular research directions. In addition， the study of the mutual relationship between economic development and agricultural carbon emissions has gradually become a current research hotspot.
