Abstract:

Straw biochar plays an important role in environmental governance and resource recycling. In order to grasp the development process of straw biochar and clarify the focus and preface direction of this research field, this article uses CiteSpace visualization software to conduct bibliometric and knowledge graph analysis on the data retrieved from the Web of Science (WOS) core collection database. The results show that the annual publication volume is on the rise, with China ranking first with a total of 3141 articles; among the global research institutions, Chinese Academy of Sciences, Ministry of Agriculture and Rural Affairs and Institute of Soil Science are representative institutions for straw biochar research; the research results in this field are mainly published in high impact factor journals such as Science of the Total Environment and Bioresource Technology, Wang Hailong from China is the scholar with the highest number of publications; the research hotspots and directions mainly include the raw materials and preparation conditions of straw biochar, the application and mechanisms of straw biochar in carbon sequestration and emission reduction, soil improvement, and pollution remediation. Overall, straw biochar is a hot topic in the resource utilization of agricultural waste. In the future, the modification and preparation of straw biochar, as well as the mechanism and long-term effects of mitigating climate change and repairing environmental pollution, will be the research hotspot and trend.
