基于文献统计的农业领域生物炭研究现状

Trends of Biochar Research on Agronomic Application Based on Literature Analysis

基于Web of Knowledge、中国知网和维普数据库,对文献数量、类别、国家、研究趋势及高被引论文国别进行了文献计量学分析。统计数据表明,自2006年开始,有关生物炭的文献数量呈显著增加,2014年发表的生物炭英文文献数量分别为2010年、2011年、2012年和2013年文献数量的6.2倍、3.7倍、2.4倍和1.5倍;发表文献总数前3位国家分别为美国、中国和澳大利亚;每篇文献平均引用次数前3位的分别为英国、澳大利亚和美国。基于文献分析结果,从生物炭生产行业标准、生物炭基肥的研究、生物炭土壤改良长期效应和生物炭副产物的利用几个方面对生物炭在农业领域研究中存在的问题进行了剖析,明确了农业领域生物炭的研究趋势,展望了其研究前景,为科研与决策者提供参考。

In this review, literatures from Web of Knowledge, China National Knowledge Infrastructure(CNKI) and VIP database on biochar research are summarized and classified. The reference number in China and abroad, the top 10 countries according to reference number, the composition of reference type and etc are investigated to show the current situation of China in this field. It is showed that the total reference number in 2014 was 6.2, 3.7, 2.4, and 1.5 times than that in 2010, 2011,2012 and 2013. The United States, China and Australia rank the top 3 countries on the reference number, while, England,Australia and the United States have the highest citations of each paper on biochar research. Finally, the emerging research trends are described and the ongoing research is prospected of biochar research in agricultural field.
