Investigating geothermal geological development dynamics based on information visualization
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.
