基于知识图谱的北运河流域水环境研究进展分析

北运河流域属海河水系,先后流经北京市、河北省廊坊市和天津市,是维持北京、廊坊、天津的重要生态廊道。为了落实国家和地方《水污染防治行动计划》,改善北运河流域水环境质量,北运河流域愈发受到科研工作者的关注。文章使用CNKI中国期刊全文数据库统计了20年内(2000-2019年)关于北运河流域水环境研究文献。通过共被引、共现关键词等分析探讨北运河流域水环境研究的基础以及研究热点与前沿。结果表明:研究分为初期萌芽阶段、中期井喷阶段和后期稳定阶段,在此期间重要贡献者较多,研究呈现多样性与深入性。北运河流域水环境各研究主题间界限清晰,领域分化鲜明,研究角度较少,研究方式相对单一。未来北运河流域水环境研究将会基于多种水质评价方法得出的水质变化规律和污染物的来源与特征,进行有针对性的治理研究,以改善目前恶劣的水质情况。

Knowledge Mapping Analysis on Water Environment of Beiyunhe River Basin

Beiyunhe River Basin belongs to Haihe River system,which is an important ecological corridor flowing through Beijing,Langfang,Hebei and Tianjin.In order to implement"Action Plan for Prevention and Control of Water Pollution"and improve the water environment quality,Beiyunhe River Basin has attracted increasing attention from researchers.In this paper,by using the CNKI database to achieve the data of water wnvironment of Beiyunhe River Basin in the past 20 years(2000-2019).Through co-citation,keyword co-occurrence analysis,the research foundation,hotspots and frontiers of water environment of Beiyunhe River Basin were explored.The results showed that:the research can be divided into the initial budding,the medium blowout,and the later stable stage.During this period,there are many important contributors,and the research shows diversity and in-depthness.The research topics of water environment of Beiyunhe River Basin are clearly defined,the fields are distinct,angles are few and methods are relatively single.In the future,the study on water environment of Beiyunhe River Basin will conduct targeted governance studies to improve water quality based on the water quality change rules and the sources and characteristics of pollutants derived from various water quality assessment methods.
