基于CNKI的我国生物炭研究趋势文献计量学分析

为客观全面地分析我国生物炭领域的发展脉络及研究动态，利用CNKI中国期刊全文数据库的出版年份、论文数量、研究机构、资助资金等指标，结合Citespace关键词可视化分析方法，系统阐述我国生物炭研究领域的概况，综合分析我国生物炭研究的主要热点及趋势。结果表明：我国生物炭领域的研究处在快速发展阶段，总发文量呈指数增长；发文量最多的研究机构是南京农业大学，被引频次最多的是西北农林科技大学；我国生物炭领域的研究主要受国家层面的基金引导；南京农业大学的潘根兴发表生物炭文章最多，被引频次最多的作者是西北农林科技大学的耿增超；发文量和总被引频次最多的期刊均是《农业环境科学学报》，篇均被引用次数最多的期刊是《应用生态学报》；我国生物炭研究的热点主要集中在肥料、土壤有机碳、土壤养分、吸附、解吸、改良剂等方向。总体而言，我国生物炭研究热点从农业领域向环境领域转变，土壤环境污染修复、土壤质量改善和土壤可持续发展、碳库储量提升是我国未来生物炭研究的主要趋势。

Bibliometric analysis on research trend of biochar in China based on CNKI

In order to reflect the development of biochar in our country objectively and comprehensively, provide macroscopical guidance for further research and enlighten researchers to quickly understand the development of biochar research in China, based on the database of CNKI, using the indicators of publication year, the number of papers, research institutions, funding and so on, combined with the Citespace keyword visualization analysis method, the general situation of China''s biochar research field and the main hot spots and trends of biochar research in China were expounded systematically. The results showed that the research in the field of biochar in China was at the stage of rapid development, the total number of papers was increasing exponentially, the most frequently cited research institution was Nanjing Agricultural University, and the most frequently cited was Northwest A&F University. Research on biochar field guided by national fund. PAN Gen-xing of Nanjing Agricultural University published most biochar articles and the author cited most frequently was GENG Zeng-chao of Northwest A&F University. The journals with the highest number of articles published and the most frequently cited journals both gained by Journal of Agro-Environmental Science. The most cited journal per article was the Journal of Applied Ecology. The research focus of biochar in China was mainly in the fields of fertilizer, soil organic carbon, soil nutrients, adsorption, desorption, modifier and so on. In general, the research focus of biochar in China has changed from agriculture to environment. Remediation of soil environmental pollution, improvement of soil quality, sustainable development of soil and enhancement of carbon pool are the main trends of biochar research in China in the future.
