纤维素类物质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,因而纤维素类物质降解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纤维素降解物质研究趋势。数据来源于Web of Science中Science Citation Index-Expended,对1992-2009年间该库收录的相关文献进行计量分析。结果表明:近几年,纤维素降解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,日本东京大学发文量位列第一;环境工程领域中影响因子较高的期刊《Bioresource Technology》对该领域的发文量较大。环境、生物及相关的能源学科和材料、医学学科是纤维素降解的主流领域。涉及的学术领域刊主要有《Biotechnology&Applied Microbiology》、《Polymer Science》、《Biochemistry&Molecular Biology》。此外,关键词分析结果表明:生物量、生物降解、热解、发酵、酶解等研究方向在近18年内逐渐成为研究热点。
As a kind of renewable biomass energy, cellulosic material is of great significance to solve the world’s energy shortage. Therefore, cellulosic material degradation technology has drawn more and more attention. The paper quantitatively analyzes the research trend of cellulose degradation materials from the perspective of literature measurement. Data from Web of Science in Science Citation Index-Expended, from 1992 to 2009 during the library included in the relevant literature measurement analysis. The results show that in recent years, the volume of cellulose degradation significantly increased. Within the statistical time frame, the United States issued the largest volume of papers. Among the research institutes, the volume of papers published by the University of Tokyo ranked the first. Bioresource Technology, a periodical with a high impact factor in the field of environmental engineering, issued a large volume of papers in this field. Environment, biology and related energy disciplines and materials, medical disciplines are the mainstream of cellulose degradation. The main academic areas are “Biotechnology & Applied Microbiology”, “Polymer Science”, “Biochemistry & Molecular Biology”. In addition, the keyword analysis results show that biomass, biodegradation, pyrolysis, fermentation, enzymatic hydrolysis and other research directions in the past 18 years has gradually become a research focus.
