【摘要】 可视化图谱可以将文献之间的关系可视化呈现，有助于发现文献之间的联系和趋势，并辅助对研究热点和主题进行识别和分析。而文献计量分析工具则可以对大量的文献数据进行量化分析，如文献产出规模、学科分布、高产作者和研究机构的排名等，有助于全面了解该领域的发展动态。通过结合可视化图谱和文献计量分析工具，可以更加深入全面地分析研究热点和主题的变化趋势，以及研究方法和地区间的差异。在本文中，为了解国内外地热地质领域研究的发展动态，对地热地质领域的世界范围内文献开展了定量定性分析，从论文产出规模、学科分布、高产作者与研究机构、研究主题及研究热点变化等方面开展了深入分析，并对未来的研究方向作出预测。研究结果表明：地热地质相关学术论文在近几年里逐渐增加，相关研究呈现多学科交叉融合的态势；美国和中国是论文产出最大的2个国家，尽管中国在发文总量和影响力上略逊于美国，但近年来后发优势明显，成果产出超越美国；“地热资源”“干热岩”“数值模拟”“水文地球化学”是学者共同关注的研究热点；地球物理、地球化学、地热学是目前研究地热地质的主要研究方法；随着时间推移，“EGS”的研究热度会逐渐下降，而“Induced seismicity”的研究热度会逐步上升。这些发现为地热地质领域的未来发展提供了有价值的参考，同时也展示了信息可视化和文献计量分析在该领域中的重要应用。更多还原

【Abstract】 Visual mapping can be used to examine relationships within the literature, and to identify connections and trends that can in turn be used to analyze popular areas and themes in prevalent research.Bibliometric analysis, on the contrary, provides a quantitative analysis of a large amount of data on the literature, such as the scale of its output, distribution of disciplines, and the rankings of prolific authors and research institutions, that can be used to comprehensively understand developments in the field.Visual mapping can be combined with tools of bibliometric analysis to examine the changing trends of areas and themes of research as well as the differences between methods of research and regions in this regard.This study reports quantitative and qualitative analyses of the literature on geothermal geology, including the scale of its output, distribution of disciplines within it, prolific authors and research institutions, and changes in its themes and subjects, and uses them to make predictions about directions of future research in the field.The results showed that academic publications on geothermal geology have gradually increased in recent years, and the relevant research has tended to be multi-disciplinary.The United States and China are the top producers of research in the field.While China has a slightly lower research output and influence in the area, it has gained certain prominent advantages in recent years, and its recent output has surpassed that of the United States.Geothermal resources, dry heat rocks, numerical simulations and hydrogeochemistry were found to be the most popular keywords in the field, while geophysics, geochemistry, and geothermology were the main general areas of research on geothermal geology.The intensity of research on “enhanced geothermal systems(EGS)” is expected to gradually decrease while that on “induced seismicity” will gradually increase.These findings provide a valuable reference for the future development of geothermal geology, and verify the usefulness of information visualization and bibliometric analysis for examining research.更多还原
