为分析地表水-地下水相互作用研究的现状和趋势，挖掘知识基础与研究热点，基于1985—2020年Web of Science（WoS）数据源，利用CiteSpace软件对检索的文献进行分析，梳理地表水-地下水相互作用领域的研究成果。结果表明：该领域发文数量分为缓慢增长、波动增长、稳定增长3个阶段，引文量逐年上升，反映该领域越来越受到研究学者的关注；地表水-地下水相互作用研究涉及多门学科，为研究提供了广泛的思路和手段。Journal of Hydrology、Environmental Earth Science、Hydrological Processes在该领域载文数量排名前3；研究力量主要分布在美国、中国和澳大利亚等；发文作者多且分散，在研究时段内发文数量最多的作者是Chunmiao Zheng（郑春苗）教授；中国科学院、美国地质调查局和澳大利亚弗林德斯大学等机构影响力较大。该领域研究的发展趋势为：较单一的地下水研究→地表水-地下水相互作用研究→陆地-水域生态系统的水体交互作用对各因素的响应研究。研究热点为：热追踪定量探究地表水-地下水交互的作用与强度；研发或改进数值模型对作用界面及不同研究对象水体交互作用进行模拟；探究水循环驱动下地表水地下水交互作用对人类活动及气候系统等的生物学、物理学和化学过程的响应。未来将注重地表水-地下水交互作用的多尺度多学科交叉研究，增强团队间合作交流。

The complex interaction between surface water and groundwater interferes with the hydrological cycle affect the ecological status of the basin.Engineering measures for artificial collection of surface water and groundwater not only play a key role in solving the uneven distribution of water resources and the contradiction between water supply and demand,but also cause a series of ecological problems.Therefore,it is particularly important to explore the relevant mechanism of the interaction between surface water and groundwater.Through bibliometric analysis,it helps researchers grasp the current research status and hotspots in this field,which provides references for related research. Based on the Web of Science (WoS) data sources from 1985 to 2020,CiteSpace bibliometric software is used to quantitatively analyze the literature on the interaction of surface water and groundwater.By analyzing the cited documents,authors,research organizations,key words,and other elements,combined with the knowledge map,it displays the current research status,frontiers,and hotspots of this field. From 1985 to 2020,the total amount of scientific research papers in this field can be divided into three stages:slow growth-fluctuating,growth-steady growth and the increase in the number of published articles.The number of articles published in Journal of Hydrology,Environmental Earth Science,Hydrological Processes ranks top three.Research forces in this field are mainly concentrated in the United States,China,Australia.The author who published the most in the research period is Chunmiao Zheng.Chinese Academy of Sciences,U.S.Geological Survey,and Flinders Univ S Australia are the most influential institutions in the world.The knowledge graphs show the top ten cited documents in this field and the top 5% key words of the literature frequency.The keywords generate six cluster tags:hyporheic zone,hydrogeochemistry,climate change,soil moisture,riparian,and submarine groundwater discharge. More scholars are paying attention to this field,which contains several interdisciplinary subjects,providing a wide range of ideas and methods for research.The changing trend of research in this field is single groundwater research→groundwater-surface water interaction research→errestrial-aquatic ecosystem water interaction research on the response to influencing factors.The research hotspots in this field in recent years are exploring the water flux,permeability and discharge of groundwater-surface water interaction through heat tracing,developing and improving numerical models to improve the fit of the model to the interaction interface and the interaction of water bodies in different research areas,analyzing the response of water interactions to the biological,physical and chemical processes of human activities and the climate system under the concept of biogeochemical cycles.In the future,the multi-scale interdisciplinary research of surface water-groundwater interaction and enhance cooperation among teams should be focused on.
