基于CiteSpace认识图谱分析粉煤灰利用研究特征

Research on Fly Ash Utilization Characteristics based on Citespace Cognitive Map Analysis

为了进一步探索粉煤灰利用相关领域的最新研究进展和热点,以CNKI数据库中中文期刊EI、SCI、核心期刊、CSSCI、CSCD中相关论文为数据基础,信息可视化软件CiteSpace为研究手段,对粉煤灰利用方面的文献从研究热点、时间分布、高频关键词、文章发表作者相关性与文章发表机构相关性进行了可视化分析,结果表明:(1)2010~2018年间,我国在粉煤灰资源化利用领域相关论文数量稳中上升;(2)目前国内粉煤灰资源化利用领域已经形成了较为完整的研究体系,大掺量粉煤灰水泥、高性能混凝土、有价金属提取、改性吸附是国内该领域发展的主要认识群组和热点研究方向;(3)研究人员和研究机构已经根据研究领域形成了较为密切的合作小组,也有部分研究人员和机构处于独立研究状态。粉煤灰利用的研究具有很强的学科交叉性,涉及环境科学、材料科学、物理学、化学、生物学等众多学科领域。

In order to further explore the latest research progress and research hotspots on fly ash utilization, classical literature and fronts, based on relevant papers of Chinese journals EI SCI core journals CSSCI and CSCD in China National Knowledge Infrastructrue (CNKI) database , using Information visualization software CiteSpace for mapping knowledge domain the visualization analysis is carried out in this paper on the fly ash utilization from the research hotspots, time distribution, high-frequency keywords, the correlation of authors and the correlation of publication institutions. The results showed that the number of papers related to the utilization of coal fly ash is steadily increasing from 2010 to 2018. A relatively complete research system in the field of coal fly ash utilization has formed in China. The main research hotspots and direction are high content fly ash cement, high performance concrete, valuable metal extraction and modification adsorption. Researchers and research institutions have formed relatively close cooperation groups according to the research field, and there are still some researchers and institutions are in the independent research state. The research of utilization of coal fly ash has a strong interdisciplinary nature, involving many disciplines such as environmental science, material science, physics, chemistry and biology.
