基于文献计量的秸秆生物炭研究进展

Research Progress of Straw Biochar Based on Bibliometrics

生物炭化利用是秸秆资源化利用的一个新方向,为阐明我国学者在秸秆生物炭方面开展的研究及发展趋势,在中国知网论文数据库,以“秸秆生物炭”为主题词进行文献检索,并对相关文献进行计量分析,揭示主要研究主题和研究机构。在文献分析的基础上,系统阐述裂解温度、时间对秸秆生物炭主要性质的影响,以及秸秆生物炭的施用对土壤主要理化性质及碳、氮物质循环的影响。结合主要研究进展,提出秸秆生物炭化肥替代定量评价、生物炭与土壤结合的微观特征与机制是未来研究的重要方向,以期为秸秆生物炭的科学高效利用提供参考依据。

Biochar utilization is a new direction of straw resource utilization.In order to clarify the research and development trend of straw biochar,straw biochar was used as the main topic for literature search in China National Knowledge Network paper database,so as to reveal the main research topics and research institutions.On the basis of literature analysis,effects of pyrolysis temperature and time on the main properties of straw biochar were systematically described,as well as the effects of straw biochar application on main physicochemical properties and carbon and nitrogen cycling in soil.Combining with the major research advances,it was suggested that quantitative evaluation of microcosmic characteristics and mechanism of biochar and soil binding was an important direction for future research,aiming at providing references for the scientific and efficient utilization of straw biochar.
