厌氧发酵产沼气研究趋势的文献计量分析

沼气作为一种可再生生物质能源,对于解决世界能源紧缺问题具有重要意义,因而厌氧发酵产沼气技术受到人们越来越多的关注。文章从文献计量角度定量分析厌氧发酵产沼气研究趋势。数据来源于Web of Science中Science Citation Index-Expended以及Derwent Innovations Index数据库,并对1992-2009年间该库收录的相关文献及相关专利进行计量分析。结果表明:近年来,厌氧发酵产沼气领域发文量显著增长。统计时间范围内,美国发文量居榜首。研究机构中,俄罗斯科学研究院发文量位列第一。环境、生物、能源相关学科是厌氧发酵产沼气的主流领域。学术期刊主要有Bioresource Technology、Water Research、Applied and Environmental Microbiology。此外,关键词分析结果表明:反应过程、反应器、预处理、混合发酵等研究方向成为近18年内的研究热点。

Bibliometric Analysis of Research Trends of Anaerobic Digestion for Methane Production

Technique of anaerobic fermentation for methane production has arisen increasing attentions,since the methane as regeneration bioenergy is important to solve the world’s energy shortage problem.Bibliometric approach was used to quantitatively assess current research trends on anaerobic digestion for methane,by using the data from Science Citation Index-Expended database and Derwent Innovations Index of the Web of Science.A metric analysis was made on related literature and patents in the two databases,which was indexed from 1992 to 2009.Results indicated that in recent years there had been a notable growth trend in publication outputs,Russian Academy of Sciences held primacy over the most publications.Mainstream of anaerobic digestion for methane research was in the environmental,biotechnology and energy related fields.Three journals including Bioresource Technology,Water Research,Applied and Environmental Microbiology were the most popular ones in this field.In addition,keyword analysis shows that the process,reactor,pretreatment and codigestion were the hotspot of the latest 18years.
