水生植物水质净化国内研究现状及发展趋势的知识图谱可视化分析
Visual Analysis of Knowledge Map of Domestic Research Status and Development Trend of Water Purification by Aquatic Plants

水生植物水质净化是解决城市河道水污染的重要手段，随着我国对生态环境的重视及污水治理投入的增加，越来越多的学者投入水生植物水质净化机理研究，为探讨该领域的研究热点及发展趋势，以CNKI收录的相关文献为研究对象，利用CiteSpcae软件，分别对论文作者、发文机构、关键词、关键词聚类图谱等进行矢量化图谱分析。分析结果表明发文量逐年增加，受政策影响较大；发文作者之间的联系较弱，基本没有形成稳定的合作团队；发文机构主要在北方和沿海或者资源较多的区域，缺乏学术合作；研究内容涵盖不同水生植物水质净化与水生植物结合不同手段水质净化2个方面。从研究内容上看，研究更加精细化、多元化、实践研究演进；“水质净化作用”、“衡水湖”、“富营养化”、“净化效果”、“组合”一直是研究的热点。
Aquatic plant water purification is an important means to solve urban river water pollution. With China’s attention to the ecological environment and the increase of investment in sewage treatment, more and more scholars have invested in the research on the mechanism of aquatic plant water purification. In order to explore the research hotspot and development trend in this field, taking the relevant literature included in CNKI as the research object and using CiteSpace software, the author Vectorization atlas analysis is carried out for document issuing organization, keyword and keyword clustering atlas. The results show that the number of documents is increasing year by year, which is greatly affected by the policy. The relationship between the authors is weak, and there is basically no stable cooperation team. Lack of academic cooperation between the main sending institutions and coastal areas or areas with more resources. The research content covers two aspects: water purification by different aquatic plants and water purification by different means combined with aquatic plants. From the perspective of research content, the research is more refined, diversified and practical. “Water purification”, “Hengshui Lake”, “eutrophication”, “purification effect” and “combination” have always been the research hotspots.
