摘要
随着经济社会发展,非点源污染已经成为重要的污染来源,学术界对其研究亦已广泛而深入,分析近30 a的非点源污染研究发展历程,有助于探寻本领域的发展演化过程、研究主题分布、追踪研究前沿。基于Web of Science核心数据库,以non-point source pollution or diffused pollution为主题词,采用文献计量工具CiteSpace对检索结果进行关键词和文献分析。通过绘制关键词时区图,揭示了不同时期研究的进展情况,并绘制了非点源污染研究主题突现演化图。经过对经典文献时区图的分析,深入挖掘了非点源污染研究内容的演进过程,得到了非点源污染的知识结构图,在此基础上分析了国内外在非点源污染研究方面的热点和探索方向。结果表明:(1)国内在该领域的相关研究发展迅速,影响力不断提升,但与国外仍存在差距;(2)在构建人与自然和谐共生、良性循环的生态文明趋势下,非点源污染防治体系必将是今后的研究热点;(3)随着非点源污染研究的深入,其在研究的广度和深度上都不断深化;(4)借助新技术,非点源污染在定量分析和防治技术方面更具创新性;(5)经过前期几十年的研究积累,研究逐渐从微观的机理方面转向宏观系统治理方面。
With the development of economy and society,non-point source pollution has grown up to be an important source of pollution where extensively and deeply academic researches also have been conducted. Analyzing the development process of non-point source pollution research in the past 30 years will assist in exploring the development and evolution process,the distribution of research topics,and the tracking of its research frontiers. Based on the Web of Science core database,we analyzed the retrieval results with keywords and literature using the bibliometric tool CiteS pace with non-point source pollution or diffused pollution as the subject words. Through drawing time-zone maps of non-point source pollution keywords,the progress of the research in different periods was revealed,and the emergent evolution map of non-point source pollution research topic was drawn.After analyzing the time-zone map of classic literature,this paper deeply excavated the evolution process of non-point source pollution research content,and obtained the knowledge structure diagram of non-point source pollution. On this basis,we analyzed the research hotspots and exploration directions of non-point source pollution at home and abroad. The results show that:(1)Domestic research in this field has developed rapidly and its influence has been increasing,while gaps still remain among foreign countries;(2) Under the trend of building a harmonious symbiosis between man and nature and a virtuous cycle of ecological civilization,the non-point source pollution prevention and control system will be a research hotspot in the future;(3) With the deepening of research on non-point source pollution,such research scope and depth will continue to increase;(4) With the help of new technologies,non-point source pollution is more innovative in quantitative analysis and prevention and control technologies.(5)After decades of research accumulation,research has gradually shifted from micro-mechanism research to macro-system governance research.
