摘要
地热能作为一种清洁可再生能源,近年来引起广泛关注,研究成果丰硕。为理清国内地热研究热点与发展态势,基于中国知网(CNKI)2000—2019年发表的文献,使用“地热”“地热流体”“浅层地热”“地热电站”“干热岩”等相关主题或关键词,利用CiteSpace软件进行可视化分析,生成作者合著网络、机构合著网络、关键词共现网络、Timeline时间线视图和突现词信息等相关图表。并从作者、研究机构两个层面分析国内文献中地热研究的主要贡献力量、知识来源、知识结构现状、跨学科特征、主要研究领域和前沿研究热点,明确国内地热当前研究热点集中在“开发利用”“干热岩”“地源热泵”上,其发展形势可观,但在理论研究、技术开发及环境保护等方面仍需加强。
As a kind of clean and renewable energy,geothermal energy has aroused wide public concern.With developing rapidly,great achivement have been made in this respect especially in recent years.In order to clarify the research focuses and trends of geothermal research in China,visualization analysis was used based on CiteSpace and literatures published from 2000 to 2019 in CNKI.According to the keywords such as geothermal,geothermal fluid,shallow geothermal energy,geothermal plant,hot dry rock and so on,the results contain following aspects:co-authorship network mapping,co-institute network mapping,co-occurrence network mapping,Timeline view and the burst term information.From the diagrams above,the main contribution of geothermal research,source,status quo of knowledge structure,interdisciplinary characteristics,main fields and frontiers are also analyzed from the perspectives of authors and institutions.Ultimately,it is concluded that the hotspots of geothermal research in China are focused on“development and utilization”,“hot dry rock”and“ground source heat pump”.Although its prospect is considerable,theoretical research,technological development and environmental protection still need to be improved.
