利用文献计量分析的方法，以web of science为数据源，VOSviewer为可视化工具，对1940-2021年开展的人工湿地研究进行了分析。结果表明:①已有研究多集中在中试规模以下人工湿地的污染物去除效果，关于大型人工湿地的污染物去除效果以及与之相应的人工湿地管理和微生物机理方面的研究属于新的研究热点;②针对大型人工湿地的研究，尤其是对其生态系统服务价值、微生物作用机理和温室气体排放等方面的研究尚不足。基于上述分析，指出未来需要以人工湿地大规模推广应用为导向，广泛开展新工艺、新材料研究，深入挖掘人工湿地在新污染去除、减污降碳以及丰富生物多样性等方面的潜在价值，强化人工湿地运行效果监测分析和总结运行管理经验将是下一步人工湿地研究和应用领域的重要发展方向。
Development Status and Prospect of Constructed Wetland Technology Based on Bibliometric Analysis
Constructed wetland,which has both pollutant removal and landscape effect,has been widely concerned by researchers and engineers.Using the method of bibliometric analysis,Web of Science as data source and VOS-viewer as visual tool,this paper analyzes the research on constructed wetlands from 1940 to 2021.The results showed that:① Most of the existing studies focused on the pollutant removal effect of constructed wetlands be-low the pilot scale,and the studies on the pollutant removal effect of large-scale constructed wetlands and the cor-responding management and microbial mechanism of constructed wetlands are new research hotspots.② The re-searches on large-scale constructed wetlands,especially on their ecosystem service value,microbial action mecha-nism and greenhouse gas emissions are insufficient.Based on the above analysis,it is proposed that in the future,the large-scale promotion and application of constructed wetlands should be guided by extensive research on new technologies and new materials.Extensive research on new technologies and new materials should be carried out.Further exploring the potential value of constructed wetlands in new pollution removal,reducing pollution and carbon,enriching biodiversity,strengthening the monitoring and analysis of the operation effect of constructed wetlands and summarizing operation and management experiences will be an important development direction in the field of constructed wetlands research and application in the future.
