A comprehensive statistical study related to biochar was conducted by using the scientometric method. The publications are mainly in the form of articles (over 16 000), accounting for 87.7% of the total, which demonstrates that researchers have great interest in this research field. Among these articles, 96.8% were written and published in English and came from 2655 different journals. The rate of increase in the annual number of publications was rapid from 2010 to 2017, and it was predicted that the cumulative number of articles concerning biochar will exceed 20 000 by the year 2020. At least one article from 154 countries or regions has been published, and every continent except Antarctica has had articles published over the past 20 years period. The percentage of collaborative articles was 71.9% and the collaboration between the USA and China has been the most fruitful. In addition, the Chinese Academy of Sciences is the research institute with the most publications. Furthermore, over 60% of the articles were published as a result of the cooperation and connection between the Chinese Academy of Sciences and the University of Chinese Academy of Sciences. The article published in had the highest citation numbers, while had the most articles (4) that were selected as the top 20 for the most-cited articles. The agriculture research category had the highest average citations among the top four categories (, environmental sciences and ecology, agriculture, chemistry and engineering).
采用科学计量学方法对与生物炭相关的文献进行了全面的统计研究。这些出版物主要以论文形式呈现（超过16000篇），占总数的87.7%，这表明研究人员对该研究领域兴趣浓厚。在这些论文中，96.8%是以英文撰写和发表的，来自2655种不同的期刊。2010年至2017年期间，出版物年数量的增长速度很快，预计到2020年，有关生物炭的论文累计数量将超过20000篇。已发表的论文至少来自154个国家或地区，在过去20年里，除南极洲外各大洲均有论文发表。合作论文的比例为71.9%，美国和中国之间的合作最为卓有成效。此外，中国科学院是发表论文最多的研究机构。此外，超过60%的论文是中国科学院与中国科学院大学合作与联系的成果。发表在[具体期刊名未给出]的论文被引次数最高，而[具体期刊名未给出]有4篇论文入选被引次数最多的前20篇。在四大类别（环境科学与生态学、农业、化学与工程）中，农业研究类别的平均被引次数最高。
