An overview of climate change vulnerability: a bibliometric analysis based on Web of Science database

Based on worldwide scholars’ 3,004 papers published in 658 academic journals in the Web of Science database on the topic of climate change vulnerability from 1991 to 2012, this paper quantitatively analyzes the global scientific performance and hot research areas in this field by adopting bibliometric method. The results show that (1) the vulnerability researches on climate change have experienced a rapid growth since 2006, and the publications are widely distributed in a large number of source journals, while the top two productive institutions are the University of East Anglia and Potsdam Institute for Climate Impact Research; (2) the cooperation at author level is on the rise, and there are closer relationships in institutional and national levels; (3) the most widely focused research topics in this field include health issues in the socioeconomic system, food security in the field of agricultural system and the issue of water resource management, etc.; (4) according to the papers from the top journals, we find that the research areas for climate change vulnerability in those publications are located in the ecological diversity, ecosystem service, water resource management and electric power supply, etc.     

The top-cited wetland articles in science citation index expanded: characteristics and hotspots

The characteristics of wetland research were investigated by a bibliometric analysis of the top-cited wetland-related articles since 1899 based on the Science Citation Index Expanded database. The analyzed aspects included the distribution of journals, and publications by country, institution, and author, with five indicators including total articles, and independent, collaborative, first-author, and corresponding-author articles. Results showed that 188 articles on wetlands have been cited at least 100 times since their publication year to 2011. The most productive stage was 1991–2000, accounting for approximately seven-tenths of the top-cited articles. The US was the leading country, followed distantly by 25 other countries/territories. The US also held primacy in terms of productive institutions. The US Geological Survey ranked first according to the five indicators. The 188 top-cited articles had 637 authors, among whom W.J. Mitsch published the most first-author and corresponding-author articles. Furthermore, substance circulation (especially of carbon), wetland organisms and vegetation, and modeling methodology were the main focuses of wetland research in the past few years. In 2011, wetland organisms and vegetation were the hottest research topics. These results were coincident with a previous study on total publications, and revealed more-specific characteristics and hotspots of wetland research.

Frontiers in lunar science based on bibliometric analysisSCIEI北大核心CSCD

月球是人类开展深空探测的首选目标,月球探测是世界各国科技竞争的制高点。开展月球科学前沿研判,对我国实施深空探测战略、规划行星科学研究路径,进而赢得未来竞争优势至关重要。基于Web of Science数据库,本文利用文献计量学方法,对月球科学领域论文产出数量、学科和期刊分布、主要国家和领先机构的竞争力、国际合作等进行了深度分析,并通过聚类分析获得当前研究热点,梳理出五大研究领域和七大前沿问题。过去20年,我国在月球科学研究取得了长足进步,但仍然存在优秀论文少、顶尖学者少、学术期刊少的问题。未来月球科学可能在三个方向上实现突破:月球的水仍将是国际月球探测和研究的重点;月球内部结构探测或是我国弯道超车的机遇;新的月球样品将进一步揭示月球形成和演化的奥秘。本研究结果可以为我国未来月球探测和研究的规划与组织提供参考。     

基于文献计量学分析水文地球化学研究进展及趋势

水文地球化学研究在可持续发展中起到重要作用,然而目前对该领域的阶段性总结分析研究还较少。本文使用文献计量学可视化分析方法,以1982年1月1日到2021年11月17日被Web of Science收录的有关水文地球化学的检索信息为基础,使用CiteSpace和 VOSviewer等软件对水文地球化学研究现状和趋势进行分析。结果表明,水文地球化学论文发文量与被引量整体呈现上升趋势,2010年以后发文数量是2010年以前发文数量的两倍,水文地球化学研究仍然具有较大的发展空间。其中,中国积极参与水文地球化学领域的研究,近几年的发文量增长幅度高于美国、德国、加拿大等发达国家,这与中国国家自然科学基金会的资助以及各个科研机构的研究分不开。通过关键词分析,1982年至2021年水文地球化学研究的主题为:地下水质量与人体健康、同位素的研究与应用、元素的迁移转化和微生物作用以及地下水-地表水水文地球化学过程。文献计量工具方法与“水岩相互作用国际学术会议”统计共同表明:不同空间尺度和环境下的水岩相互作用、同位素技术的开发与应用、生物地球化学以及地下水质量是未来水文地球化学领域的主要研究趋势。     

Hydrogeology and groundwater ecology: Does each inform the other?

The known, perceived and potential relationships between hydrogeology and groundwater ecology are explored, along with the spatial and temporal scale of these relations, the limit of knowledge and areas in need of research. Issues concerned with the subterranean part of the water cycle are considered from the perspective of the biology of those invertebrate animals that live, of necessity, in groundwater and the microbiological milieu essential for their survival. Groundwater ecosystems are placed in a hydrogeological context including the groundwater evolution along a flowpath, the significance of the biodiversity and of the ecosystem services potentially provided. This is considered against a background of three major components essential to the functioning of groundwater ecosystems, each of which can be affected by activities over which hydrogeologists often have control, and each, in turn, may have implications for groundwater management; these are, a place to live, oxygen and food (energy). New techniques and increasing awareness amongst hydrogeologists of the diversity and broad distribution of groundwater ecosystems offer new opportunities to develop cross disciplinary work between hydrogeologists and groundwater ecologists, already demonstrated to be a field for collaboration with broad benefits.
