摘要 采用Citespace文献计量学软件对Web of Science和CNKI的土壤有机碳科学领域的文献进行了梳理统计。通过分析关键词的频次、中心性、聚类和突变词,厘清近30年国内外土壤有机碳研究领域的发展脉络,分析探讨相关研究的发展方向。结果表明:国际上土壤有机碳研究发展过程可分为3个阶段,研究内容经历了由以碳循环为核心的土壤有机碳动态学研究、全球变化为主的问题导向研究向以农业管理为主的土壤固碳封存研究转变。国内土壤有机碳研究发展时间较短,研究方法和研究体系不够完善,研究内容经历了由农业生产与发展为主的土壤有机碳基础研究,土壤有机碳的循环与分布为主的研究向碳储量与农田碳汇为主的研究转变。国内相关研究起步较晚,与国际相比在研究内容、研究尺度、问题导向、发展脉络上存在差异。目前,土壤有机碳储量和农业管理为核心的土壤固碳封存的相关研究是国内外土壤有机碳研究领域的总体发展趋势。 Citespace bibliometrics software was used to sort out the literature regarding soil organic science in Web of Science and CNKI. By analyzing the frequency, centrality and clustering of keywords, and mutation words, we clarify the development of soil organic carbon research at home and abroad over the last 30 years, as well as analyze and discuss the development direction of related research. The results show that the international development process of soil organic carbon research can be divided into three stages;the research content has changed from dynamics of soil organic carbon with carbon cycle as the core and the problem-oriented research based on global change to soil carbon sequestration in agricultural management;the development time of research on soil organic carbon in China is relatively short, and the research methods and research systems are not perfect;the research content has changed from the basic research based on agricultural production and development, and soil organic carbon circulation and distribution to reserves and farmland carbon sink;in comparison, domestic research on SOC started later, and has obvious difference with international research in the aspects of research content, research scale, problem orientation, and development context. At present, the research on soil organic carbon storage and soil carbon sequestration in agricultural management is the overall development trend of soil organic carbon research at home and abroad.
