摘要
为揭示长江洪水研究的现状与发展趋势,运用文献计量学等方法,基于SCIE与CSCD文献数据库对长江洪水研究的发文年代、国际合作、研究机构、核心作者、期刊分布、热点关键词等方面进行了系统性的分析。结果表明:①SCIE与CSCD发文量在1998年后迅速增长,尤其是SCIE文献增长显著,中国与美国、德国等发达国家合作发文较多;②中国科学院的英文和中文文献数量均居于领先水平,约占SCIE与CSCD总文献的31%和23%,中、外文核心作者分别约占作者总数的21%和27%, SCIE文献发表在《Journal of Hydrology》期刊最多,各约占总文献的4%,CSCD文献发表在《长江流域资源与环境》和《长江科学院院报》的最多,各占全部文献的7.28%;③长江洪水研究热点关键词频次>20的主要是三峡、降水、气候变化、沉积、洪涝灾害等,这些热点关键词反映了长江洪水发生机制及灾害缓解研究的发展态势。研究成果可以为未来长江洪水相关研究提供参考。
Bibliometric approach was employed in this paper to reveal the status and development trends of research on Changjiang (Yangtze) River flood based on SCIE and CSCD. The publication age, cooperative nations, core authors, author’s affiliations, and hot keywords were analyzed in detail. Results unveiled that:(1) the number of papers, in particular, SCIE papers, has surged after 1998, and the United States and Germany are top two countries which cooperate with China the most in the research.(2) The Chinese Academy of Sciences has been taking a leading role in contributing papers in English and Chinese languages, accounting for 31% and 23% of the total number of papers in SCIE and CSCD, respectively. Core authors of SCIE and the CSCD take up 27% and 21% of the total number of authors respectively. In SCIE, Journal of Hydrology was the top journal publishing research papers on Changjiang River flood, covering a proportion of 4%;in CSCD, Resources and Environment in the Yangtze Basin and Journal of Yangtze River Scientific Research Institute are top two periodicals publishing research papers on Changjiang River flood, each occupying a proportion of 7.28%.(3) Key words with a frequency over 20% included Three Gorges Reservoir, precipitation, climate change, sediment, and flood disaster. These key words had reflected the development of flood research in mechanism of disaster occurrence and disaster mitigation. Bibliometric information could provide reference for future flood related research in the Yangtze River Basin.
