基于文献计量的干旱地区地下水领域研究进展

Research progresses of arid area groundwater based on bibliometrics analysis

对于水资源匮乏的干旱地区来说,地下水资源的保护、研究、利用意义重大。本文以文献计量学为基础,根据中国知网文献数据库提供的数据,搜集2000年至2020年的所有关于“干旱区地下水”这一主题的研究论文,并运用Citespace、Excel等软件得到该主题的发文量、研究者、科研机构、关键词的共现网络,在这些工作的基础上整理出国内近20 a有关干旱地区地下水方面的研究进展。研究结果表明:“干旱区地下水”方面的论文数量自2002年之后每年稳步增加;出现频次较高的关键词包括地下水、干旱区、水资源、地下水埋深、塔里木河下游、数值模拟、地下水位、生态环境、西北干旱区、人类活动等;研究前沿越来越细化、科学问题越来越具体、研究手段越来越丰富多样,比如采用同位素技术分析地下水的来源。该研究领域经过起步阶段、平稳发展阶段,目前已进入活跃阶段和持续阶段。

It is of great significance to protect,study and utilize groundwater resources in arid areas where water resources are scarce.Based on bibliometrics and the data provided by the bibliometrics database of CNKI,in this study,we collected all research papers on the topic of"groundwater in Arid Zone"from 2000 to 2020,and used Citespace,Excel and other softwares to get the number of papers published,researchers,research institutions and the co-occurrence network of keywords on this topic.On the basis of these works,the research progresses of groundwater in arid areas of China in recent 20 years were summarized.The results showed that the number of papers on groundwater in arid area has been increasing steadily since 2002.Keywords with high frequency included groundwater,arid area,water resource,groundwater depth,lower reaches of Tarim River,numerical simulation,groundwater level,ecological environment,arid area of northwest China,human activity among others.The research frontier is more and more detailed,the scientific problems are more and more specific,and the research methods are more and more diverse.As an example,isotope technology has been used to analyze the source of groundwater.After the initial stage and steady development stage,the research field has entered the active and continuous stage.
