基于文献计量的汉江流域研究态势分析

基于Web of Science(WOS)和中国知网(CNKI)文献数据库,采用文献计量学的原理方法,对2000—2020年间汉江流域相关研究的发文量、国际合作、主要作者、主要机构、期刊分布和关键词等进行了分析。结果表明:2000—2020年期间WOS和CNKI数据库收录汉江流域相关的论文分别有560篇和553篇,且基本保持稳定增长状态。WOS中相关论文涉及的国家有46个,其中我国的发文量占比86%,主要与美国、澳大利亚等国家合作。来自中国科学院武汉植物园的张全发研究员共发表43篇中外文论文,位列全球之首,且为WOS数据库中作者合作网络的中心。WOS数据库中论文发表在Journal of Hydroloy期刊的数量最多,占比4%以上;CNKI数据库中《长江流域与资源环境》发文量最多,占比7.7%。“气候变化”和“丹江口水库”是两个数据库中共同的高频关键词,表明汉江流域主要关注丹江口库区及气候变化对流域的影响。该研究成果可以为汉江流域未来的研究提供科学支撑。

Bibliometric Analysis of Research Trend of Hanjiang River Basin

The number of research papers,cooperative nations,core authors,major institutions,source publications and key words of Hanjiang River research from 2000 to 2020 are analyzed by using bibliometric approach based on WOS and CNKI databases.Results demonstrate that: the WOS and CNKI databases collected 560 and 533 research papers regarding Hanjiang River Basin from 2000 to 2020,respectively,and this number maintained a steady growth.Authors from 46 countries involved in papers indexed by WOS,of which 86% are from China,mainly in cooperation with the United States and Australia.Chinese researcher Zhang Quan-fa from Wuhan Botanical Garden of Chinese Academy of Sciences has published 43 papers in total,ranking first in the world,staying in the center of the author's cooperation network in the WOS database.The Journal of Hydrology published the largest number of papers in the WOS database,accounting for more than 4%,while the Yangtze River Basin,Resources and Environment ranks top in the CNKI database,covering a proportion of 7.7%.Climate Change and Dangjiangkou Reservoir are common high-frequency keywords in the two databases,indicating that the Hanjiang River Basin is mainly concerned with the Danjiangkou Reservoir area and the impact of climate change on the river basin.The research findings offer scientific support for future research on the Hanjiang River Basin.
