随着湿地研究的发展,小微湿地开始受到研究者和政策制定者的共同关注。我国小微湿地的研究尚处于起步阶段,仅有少数文献介绍了小微湿地的概念、管理和营造技术。为了深入了解小微湿地的研究现状,检索了web of science核心数据库1990年至今关于小微湿地相关的研究论文,并运用CiteSpace软件对检索到的3072篇小微湿地研究文献的逐年发表数量、学科分布、核心作者与国家地区、关键词和文献被引用情况进行了可视化分析,追溯探讨了小微湿地的发展和研究动态及热点。结果显示,1990年以来,针对小微湿地的研究呈持续上升态势;小微湿地研究涉及生命科学、环境、生态、水产等137个学科,可以归为16个聚类,主体研究的各个聚类间有着继承和衍生关系,交叉重叠较多;小微湿地对全球变化的响应与适应及在"碳中和"中的贡献、小微湿地的生态服务功能及适应性管理、小微湿地对面源污染的净化功能可能是未来几年的研究热点,城市小微湿地的研究和工程运用也将成为本研究领域的增长点。
With the development of wetland research, small and micro wetlands are receiving more and more attention of researchers and policy makers. However, the research of small and micro wetlands in China is still in its starting, with few literatures introducing the concept, management and construction technology. In order to understand the research status of small and micro wetlands, CiteSpace visualization and quantitative methods were used to analyze 3072 published papers on small and micro wetlands, which were collected from Web of Science Core Collection of Science Citation Index Expanded Database. The number of papers published annually, subjects’ distribution, information of core authors and core countries, keywords and citation by other papers were analyzed. The future development, research trends and hotspots of small and micro wetlands were discussed as well. The results showed that the number of published papers has increased steadily since 1990. The study of small and micro wetlands involved 137 subjects such as life sciences, environmental sciences, ecology, aquatic products science and so on, which could be classified into 16 clusters. There were overlapping among clusters of the main studies as one cluster may have inheritance and derivative relationship from another. The response and adaptation of small and micro wetlands to global change and their contribution to carbon neutralization, the purification effect of small and micro wetlands on wastewater, especially the treatment of non-point source pollution, how the ecological function of small and micro wetlands serve the rural revitalization, the research and engineering application of urban small and micro wetlands may become the growth points in this research field.
