The massive amounts of publication data are highly valuable, because in addition to the advancement in science, technology, and policy, such data can provide critical information and guidance on what have been published, what topical changes have evolved, and what are the trending fields deserving more attention. In the 21st century, biochar has played an indispensable role in the long-term global development strategies in response to "Carbon neutralization", "Agricultural management", and "Environmental restoration", and accumulated many high-quality publications. Herein, this study provides a new data-driven bibliometric analysis strategy and framework for mining the core content of massive literature data, and aims at bringing unique insights for the research prospects as well as opportunities of biochar. The results show that biochar researches have made great progress from 1999 to 2020, but cross-disciplinary teamwork should be further emphasized. The research frontier identification reveals that sewage treatment, efficient removal, and functional composite materials will be the issues which must be paid continual attention at present and in the future. Furthermore, studies on global climate impact, biomass resource utilization, carbon sequestration, carbon cycle, and even the negative effects of biochar have gradually begun to be taken seriously.
大量的文献数据具有很高的价值，因为除了科学、技术和政策的进步外，这些数据还可以提供关于已经发表的内容、出现的主题变化以及值得更多关注的热门领域的关键信息和指导。在 21 世纪，生物炭在应对“碳中和”、“农业管理”和“环境修复”的长期全球发展战略中发挥了不可或缺的作用，并积累了许多高质量的出版物。在此，本研究提出了一种新的数据驱动的文献计量分析策略和框架，用于挖掘大量文献数据的核心内容，旨在为生物炭的研究前景和机遇提供独特的见解。结果表明，1999 年至 2020 年，生物炭研究取得了很大进展，但应进一步强调跨学科团队合作。研究前沿的识别表明，污水处理、高效去除和功能复合材料将是当前和未来必须持续关注的问题。此外，对全球气候影响、生物质资源利用、碳封存、碳循环，甚至生物炭的负面影响的研究也逐渐开始受到重视。
