基于Citespace分析的秸秆能源化利用技术研究进展

Advancement of Energetic Utilization of Straw Biomass Research Based on Citespace Analysis

秸秆的处理处置是农业农村生态环境保护重点关注的方向,了解秸秆资源化利用领域研究应用的热点和前沿,有助于我国制定并优化相关的政策规划。基于文献计量软件Citespace及Web of Science核心数据库,对秸秆能源化领域进行了可视化分析,展现秸秆能源化利用的国际趋势。结果表明,20多年来论文发文量呈现不断增长的趋势,排名前四的国家分别为中国、美国、德国、法国。中美两国科学家在各自领域形成了强大的科研团队,发文量Top10学者中共有9名中美学者。秸秆能源化利用研究主要围绕生物质生产燃料的机理研究、基于物理方法的秸秆能源化利用、秸秆厌氧发酵生产甲烷、氢气以及能源化利用过程中的环境影响等5个主要研究主题开展。秸秆能源化研究仍处于快速发展期,未来秸秆的预处理、生物发酵、全生命周期研究仍将是研究热点。

The treatment and disposal of straw is one of the key focuses of agricultural and rural ecological environmental protection.Through understanding the hotpots and frontiers of energetic utilization of straw biomass,it is helpful to develop and optimize the policies and strategies for straw utilization.With taking the core collection of Web of science as data sources and using the Citespace knowledge mapping analysis tool,this research conducts the visual analysis and presents the global tendency of straw energy utilization field.The results show that the amount of international literatures is increasing in 20 years and the Top 4 countries include China,United States,Germany and France.Scientists from China and the United States have built strong research teams in their respective fields.Nine scholars in the top10 in terms of the publication number are from China and the United States.The research on the straw energy utilizations mainly focus on five topics:the mechanism of biomass fuel production,physically energetic utilization of straw biomass,the anaerobic fermentation of straw to produce methane and hydrogen,and the environmental impact during the energetic utilization process of straw biomass.The research on straw energy utilization is still in a rapid development period,and the pre-treatment,biological fermentation,and full life cycle research of straw will continue to be hotspots in the future.
