基于CiteSpace的中国河流水质评价研究热点和趋势分析

Research Status and Perspectives of River Water Quality Assessment in China Based on Citesspace

以CNKI数据库中1980至2019年9月的487篇文献为原始数据,基于文献计量学分析方法,利用CiteSpace软件探究中国河流水质评价研究现状及趋势。结果表明:中国河流水质评价研究的发文量总体呈上升趋势,作者之间合作关系弱,综合水质标识指数法、模糊综合评价法、综合污染指数法、主成分分析法等水质评价方法是中国河流水质评价的研究热点,中国河流水质评价研究往改善水体黑臭状况和进行水质监测研究方向发展。

A total of 487 articles published in the CNKI databases from 1980 to September 2019 were analyzed using bibiometric analysis with Citespace software.The aim of the study was to make a knowledge map about Chinese river water quality assessment research to explore the research status and perspectivesin this area.The results showed that the number of papers published aboutChinese river water quality assessment research was on the growing stage;the cooperation between authors was weak;water quality assessment methods such as comprehensive water quality identification index,fuzzy comprehensive evaluation,comprehensive pollution index and principal component analysis were the hot spots of river water quality assessmentin China;the research trend of river water quality assessment in China was to develop the malodorous black water improvement and monitoring research which is beneficial to water quality management.
