- Abstract:
-
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.
