摘要
生物炭素有“黑色黄金”之称,在农业领域得到广泛应用。为了揭示生物炭农田应用领域研究热点与发展趋势,利用文献计量学方法和CiteSpace软件系统梳理了该领域主要研究力量(国家、机构、作者),归纳了该领域的主要研究主题。研究发现:在生物炭农田利用领域,中国学者表现十分活跃,但国际影响力有待进一步加强。经过15年的发展,该领域涌现出大量研究热点和研究前沿,2007—2011年的研究热点是生物炭的土壤改良效果,该阶段的研究前沿是污泥基生物炭的安全施用与土壤改良效果。2012—2016年的研究热点是生物炭的碳封存与温室气体减排效应,该阶段的研究前沿是温室气体的转化与减排机理。2017—2021年的研究热点是生物炭的土壤修复效果,该阶段的研究前沿是生物炭(改性生物炭、生物炭复合物等)对重金属、有机污染物的矿化/降解机理。
Biochar is known as“black gold”and widely used in agriculture.In order to reveal the hotspots and emerging trends in the research area of biochar application in farmland,Citespace software and bibliometrics method were used to sort out the main research terms on the country,institution and author levels,and summarizes the main research topics in this field.The results show that Chinese scholars are very active in the research area of biochar application in farmland,but their international influence needs to be further strengthened.After 15 years of development,a number of research fronts and hotspots have emerged in this research area,and mainly including the research hotspot in the research period of 2007-2011 is the soil amelioration effect of biochar and the research front in this period is security application of sludge derived biochar and its soil amelioration effect.The research hotspot in the research period of 2012-2016 is the effect of biochar on carbon sequestration and greenhouse gas emission reduction,and the research front in this period is the transformation and emission reduction mechanism of greenhouse gases.The research hotspot in the research period of 2017-2021 is the soil remediation effect of biochar,and the research front in this period is the immobilization/degradation mechanism of heavy metals/organic pollutants by biochar and its derivatives.
