基于WOS数据库的饮用水源地评价知识图谱分析

Knowledge mapping analysis of drinking-water source evaluation based on Web of Science

基于Web of Science(WOS)数据库中收录的饮用水源地评价学术论文,综合运用知识图谱构建工具和传统文献研究方法,建立了饮用水源地评价知识图谱,分析了其年代发展演化过程,并给出其未来发展趋势。结果表明:该领域经历了早期积累、持续发展和快速发展三大阶段,呈现以环境科学、环境工程和水资源学为核心,多学科交叉融合发展态势;研究主题丰富,主题数量和热度分布总体上呈现不断扩展和持续集中并存的发展态势;不同国家或地区对饮用水源地评价研究的偏好主要由本地区主要饮用水源地类型及其面临的污染胁迫类型所决定;当前的重要研究前沿热点涉及新兴污染物的危害、污染物去除工艺效果、湖库水源地富营养化、水质评价方法、水污染的人类健康风险、污染物检测新技术、气候变化对饮用水的影响、工农业生产与饮用水安全、水生态系统健康等9个方面。指出未来应充分归纳各类饮用水源地的系统特征及其对评价主题的约束作用,建立智慧的饮用水源地监测-评估-预测-预警-响应集成技术体系,加强饮用水源地系统健康定量表征、演化模式和驱动机制研究。

Based on the documents on drinking-water source evaluation included in Web of Science(WOS),the knowledge domain map of drinking-water source evaluation was established by the comprehensive use of bibliometrics tools and traditional literature review methods,the historical development and evolution process was analyzed,and the future development trend was also given.The results show that this field has experienced three stages of early accumulation,sustained development and rapid expansion,showing a trend of multi-disciplinary integration with environmental science,environmental engineering and water resources as the core.The research topics are abundant,showing a trend of continuous expansion,but the heat distribution of the topics generally show a continuous concentration trend.The preference of different countries or regions for drinking-water source evaluation research is mainly determined by the major type of drinking-water sources and the main pollution stress that they face.At present,the important research frontiers and hot spots involve 9 aspects,such as the harm of emerging pollutants,the effect of pollutant removal process,the eutrophication of lakes and reservoirs,water quality assessment methods,human health risks of water pollution,new technologies for pollutant detection,the impact of climate change on drinking-water source,the relationship of industrial or agricultural production and drinking-water safety,and the ecosystem health in drinking-water source.In the future,it is necessary to fully summarize the system characteristics of different types of drinking-water sources and establish an intelligence-integrated technology system of monitoring,assessment,forecasting,early-warning and response for drinking-water sources.Particular attention should be paid to the quantitative characterization,evolution modes and driving mechanism of drinking-water source system health.
