为了解国内外地下水污染领域研究现状和重点，梳理2009-2019年国内外学术期刊收录的地下水污染领域高质量文献8117篇，利用可视化软件CiteSpaceV.5.6.R3绘制科学知识图谱。通过对地下水研究领域论文发文量、研究内容、研究机构和发文作者统计、聚类和可视化，多维度发掘地下水污染研究的整体形势。结果显示：地下水污染研究领域科研论文发文量总体呈增长趋势，研究重点主要围绕污染物特征、污染评价和污染修复等3个方面展开，硝酸盐、砷污染已成为地下水污染的研究重点；中国地质科学院水文地质环境地质研究所和吉林大学对国内地下水污染领域的发展具有重要贡献，且研究团队随时间呈分散式、多元化发展；中国地质大学、中国科学院和美国地质调查局是最具国际影响力的机构，中国地质大学（武汉）王焰新院士团队在地下水污染研究领域极具国际影响力。在我国生态文明建设需求下，地下水污染修复由理论研究向污染场地应用转化仍是当前研究的趋势。

To understand the research status and key points in the field of groundwater pollution at home and abroad,8117 high quality pieces of literature in the field of groundwater pollution were collected from academic journals from 2009 to 2019, and the scientific knowledge map was drawn by the visualization soft ware CiteSpaceV.5.6.R3. Through the statistics, clustering, and visualization of the paper volume, research content, research institutions, and authors of groundwater research, the overall situation of groundwater pollution research is explored in multiple dimensions.The results show that: the total amount of scierrtific research papers in the field of groundwater pollution research is increasing, the research fouses on three aspects: pollutant characteristics, pollution evaluation, and pollution remediation, nitrate and arsenic pollution has become the research focus of groundwater pollution; the Institute of Hydrogeology and Environmental Geology of the Chinese A cademy of Geological Sciences and Jilin University have made im portant contributions to the development of domestic groundwater polution, and the research team has developed decentralized and diversified over time China University of Geosciences, Chinese Academy of Sciences, and USGS are the most inf luential institutions in the world. Wang Yanxin's team of academicians from China University of Geosciences(Wuhan) has great international influence in the field of groundwater pollution research. Under the demand of ecological civilization construction in China, the transformation of groundwater pollution remediation from theoretical research to the application of contaminated sites is still the current research trend.
