再生水研究的发展态势与研究热点分析——基于CiteSpace的图谱量化研究

Development trend and research hotspots of reclaimed water research: visualize quantitative research based on CiteSpace

全球水资源短缺形势日益严峻,再生水作为水资源替代品受到越来越多的学者关注,对再生水研究领域进行科学的梳理显得尤为必要。该文以Web of Science核心数据库中1988年至2018年近30年的4263篇文献为原始数据,应用知识图谱工具Cite SpaceⅤ绘制再生水研究知识图谱,以各阶段再生水研究前沿为基础,从微观、中观、宏观的角度分析了近30年来再生水研究的发展状况,并识别了近三年来再生水研究热点,最后对再生水后续研究提出了跨学科合作和加强管理应用研究的建议。

With the increasingly severe situation of water resource scarcity,reclaimed water attracts more and more scholars’attention.It is necessary to present a scientific overview on reclaimed water research field.We collected 4263 articles from the"Wed of Science"core database as original date,and used the Knowledge Mapping software CiteSpaceⅤto describe the knowledge maps of reclaimed water research.Based on the research of reclaimed water at various stages,we analyzed the development status of reclaimed water research in recent thirty years from three scales:micro-level,middle-level and macro-level.Results of the study show that:1)Research priorities at various stages change constantly.2)There are three research groups about waste water reuse technology,security control and risk assess management,and reclaimed water application management has respectively become the main research direction at each stage.3)Research on reclaimed water around the word has gradually become the heated topic.4)Research hotspots in recently years about reclaimed water include"China","irrigation","in vitro bioassay","public acceptance"and"risk assessment".Finally,suggestions about strengthening interdisciplinary cooperation and paying more attention to research on reclaimed water management are proposed.
