基于文献计量学近20年国内外地下水数值模拟研究进展及展望

RESEARCH PROGRESS AND PROSPECT OF NUMERICAL SIMULATION OF GROUNDWATER BASED ON BIBLIOMETRICS IN THE PAST TWO DECADES HAINAN ISLAND BASED ON MAIN CONTROL ELEMENTS

地下水数值模拟作为解决地下水问题的重要手段,前人的大多数文献综述对地下水数值模拟领域进行了系统的总结,但缺乏量化分析,仅通过综述并不能全面揭示地下水数值模拟领域发展情况。本研究通过整理地下水模拟研究领域2000—2021年CNKI数据库发表的950篇高质量论文和Web of Science^(TM)核心合集数据库发表的4669篇高质量论文,作为数据源,基于CiteSpace软件从发文量、研究机构和作者共现、关键词聚类和突现等知识图谱几个方面进行对比分析。结果表明:2000年以来,地下水数值模拟领域的发文量整体呈增长态势,说明该研究方向获得广泛的关注。国内外相关研究多以学校或研究院所为单位,多学校及研究院所、国内与国外学者以及研究团队之间的合作交流不显著,呈分散式、多元化发展。其中南京大学的吴吉春团队、吉林大学的卢文喜团队,在CNKI数据库和Web of Science^(TM)核心合集数据库中发文量均较高,提高了我国在地下水数值模拟研究领域的国际影响力。但我国整体中介中心性较低,表明我国研究成果在国际上的影响力还有很大提升空间。当前地下水资源、重金属污染防控及海平面上升引起的海水入侵是地下水数值模拟领域的研究热点。综上,地下水数值模拟研究领域正处于活跃的发展状态,未来的研究视角也将更为多样化,不同机构、地区、国家间的学术交流合作也将会更密切。该研究可为全面了解2000年以来地下水数值模拟领域的整体研究现状以及发展趋势提供参考。

As an important way to solve the groundwater problem,most of the previous literature reviews have given a systematic summary in the field of groundwater numerical simulation,but there is a lack of quantitative analysis,and the review alone cannot fully reveal the development of groundwater numerical simulation.By collating 950 high-quality papers published in the CNKI database and 4669 in the Web of Science^(TM)core collection database from 2000 to 2021 as a data source,a comparative analysis was carried out based on the CiteSpace software,with the knowledge graphs such as co-occurrence of publication volume,research institutions and authors,keyword clustering and burst detection,etc.The results showed that:since 2000,the overall volume of publications in the field of numerical simulation of groundwater has shown an increasing trend,indicating that this research direction has received widespread attention.Most of the relevant researches in domestic and abroad are based on universities or research institutes,and the cooperation and exchange is not significant among universities and research institutes,domestic and foreign scholars.In general,the researches have shown the characteristics of scatteration and diversification.Among them,Wu Jichun’s team at Nanjing University and Lu Wenxi’s team at Jilin University published a large amount of articles in the two databases above,improving China’s international influence in the field of numerical groundwater simulation.Overall,though,the between centrality in China is low,indicating that there is still room for improvement in the international influence of China’s research results.At present,groundwater resources,heavy metal pollution prevention and control and seawater intrusion caused by sea level rise are the research hotspots in the field of numerical simulation of groundwater.In summary,the research of numerical simulation of groundwater is in a state of active development,and the future research perspectives will be more diversified,and the academic exchanges and cooperation between different institutions,regions and countries will be promoted.The study can provide a comprehensive understanding of the overall research status and development trend in the field of numerical simulation of groundwater since 2000.
