Abstract:

In order to accurately grasp the international development trend of groundwater research,the hot research area and the research power distribution,discuss the advantage and disadvantage of research of China,top 10% papers ranked by cited number from all the papers published between 1950 ~ 2015 in SCIE and SSCI database of Web of Science are quantitative analyzed by Thomson Data Analyzer ( TDA) and UCINET software. The results show that: USA,Canada and UK are the top3 influential country in groundwater research. 7 of the top10 influential institutions are from USA and the United States Geological Survey ( USGS) is the most influential institution among the top10. Environmental science and ecology,water resources and engineering science are the most related subject with groundwater research. Soil,arsenic and nitrate are found being the top3 hotspots between 20 themes of recent 10 years. Rsearches of international groundwater place greater emphasis on the impact of agricultural production on groundwater,however,China have many researches on the prevention and control of arsenic pollution and the simulation analysis of groundwater pollution process. In addition,there are many researches on agricultural science but lack of researches on Oceanography in China. Meanwhile,there are problems like low output of high cited papers,short of international cooperation,weak study of key fields and deficiencies of characteristic research in China groundwater research. At last,some suggestions for further groundwater research in china are put forward.
