基于CiteSpace的我国耕地碳排放研究现状分析与展望

Analysis and Prospect of the Research Status of Cultivated Land Carbon Emissions in China Based on CiteSpace

摘要: 本文通过CiteSpace软件对2010~2025年我国耕地碳排放领域的相关文献进行可视化分析，深入探讨该领域的研究现状、热点及前沿动态。研究发现，我国耕地碳排放研究可分为缓慢增长、平稳增长和快速增长三个阶段，其发文量变化与国际气候协定及国内相关政策的出台密切相关。在研究内容上，主要聚焦于耕地碳排放的测算方法、时空分异规律、影响因素以及与经济发展的关系等方面。关键词共现和聚类分析结果显示，“耕地”“碳排放”“碳汇”“土地利用”等为高频关键词，反映出研究集中于耕地系统的碳排放与碳汇功能及其影响因素；“碳中和”“碳减排”等关键词的突现则表明研究逐渐向应用层面转变。此外，耕地碳排放领域的研究力量相对分散，尽管已形成部分核心作者团队和机构，但整体合作网络密度较低，跨机构、跨学科的合作尚待加强。未来研究应进一步深化微观层面探讨，强化合作机制，优化研究方法与模型，以推动耕地碳排放研究向更深入、系统的方向发展，为我国碳中和目标的实现提供有力支撑。

Abstract: This paper uses CiteSpace software to visually analyze the relevant literature in the field of cultivated land carbon emissions in China from 2010 to 2025, and deeply discusses the research status, hotspots and frontier dynamics in this field. The study found that the research on carbon emissions from cultivated land in China can be divided into three stages: slow growth, steady growth and rapid growth. The change in the number of publications is closely related to the introduction of international climate agreements and domestic related policies. In terms of research content, it mainly focuses on the calculation method of cultivated land carbon emissions, the law of spatial and temporal differentiation, the influencing factors and the relationship with economic development. The results of keyword co-occurrence and cluster analysis showed that “cultivated land”, “carbon emission”, “carbon sink” and “land use” were high-frequency keywords, reflecting that the research focused on the carbon emission and carbon sink function of cultivated land system and its influencing factors. The emergence of keywords such as “carbon neutrality” and “carbon emission reduction” indicates that the research has gradually shifted to the application level. In addition, the research strength in the field of cultivated land carbon emissions is relatively scattered. Although some core author teams and institutions have been formed, the overall cooperation network density is low, and cross-institutional and interdisciplinary cooperation needs to be strengthened. Future research should further deepen the micro-level discussion, strengthen the cooperation mechanism, and optimize research methods and models, so as to promote the research of cultivated land carbon emissions to a more in-depth and systematic direction, and provide strong support for the realization of China’s carbon neutrality goals.
