摘要
基于Web of Science与CNKI数据库,利用文献计量分析方法,分析生物炭影响土壤有机碳领域的发文情况、研究力量、关键文献和研究热点。结果表明:年发文量呈上升趋势;中、美两国在该领域占据主导地位;南京农业大学、西北农林科技大学、中国科学院等研究机构具有较高的国际影响力。潘根兴、Ok Young Sik分别是中、英文发文量较多的学者,Johannes Lehmann是共被引频次较高的学者。该领域研究热点为生物炭制备工艺及原料来源对土壤固碳减排、土壤质量及作物产量的影响。未来应加强长期定位实验探索生物炭影响土壤有机碳矿化的内在机制,并注重生物炭的生态风险评估。
This paper used the bibliometric analysis to analyze the number of publications,sources of researchers(i.e.,countries,institutions,and scholars),key literature,and research hotspot based on Web of Science and CNKI.The results showed that the annual number of published papers significantly increased.China and USA played a dominating role in this field.Research institutions,such as Nanjing Agricultural University,Northwest A&F University,Chinese Academy of Sciences,have got much international influence.Pan Genxing and Ok Young Sikis the scholars with more publications in Chinese and English,respectively.Johannes Lehmann is the scholar with highest co-citation frequency.At present,the research focus in this field is the effects of biochar preparation technology and raw material source on carbon sequestration and carbon emission reduction,soil quality and crop yield.In the future,long-term positioning experiments should be strengthened to explore the internal mechanism of biochar affecting soil organic carbon mineralization under different soil types,and attention should be paid to the ecological environmental risk assessment of biochar.
