摘要
非点源污染已经成为水污染的主要形式,也是学界的研究热点。以Web of Science (WOS)核心数据库中1997~2017年的期刊文献作为数据源,以“Non-point pollution (非点源污染)”为检索词进行检索,采用Bibexcel对检索结果进行统计分析,并借助可视化软件Pejak绘制共词网络图,同时采用SPSS软件对提取出的28个超高频关键词进行系统聚类分析,划分为4个群集。最后从研究方法、研究视角和研究对象三个方面对相关文献进行特征分析,探讨国外非点源污染研究特征及研究热点,从而为我国非点源污染研究提供有益参考。
Non-point source pollution has become the main form of water pollution, and it is also a research hotspot in the academic circle. Using the 1997~2017 journal literature in the core database of Web of Science (WOS) as the data source, the search was conducted by using “Non-point pollution” as the search term, and the results of the search were statistically analyzed by Bibexcel. The visualization software Pejak was used to draw the common word network diagram, and the 28 highest frequency keywords extracted by SPSS software were systematically clustered and analyzed into four clusters. Finally, the characteristics of relevant literatures are analyzed from three aspects: research methods, research perspectives and research objects. The research characteristics and research hotspots of non-point source pollution in foreign countries are discussed, which provides a useful reference for non-point source pollution research in China.
