Abstract:
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.
