Bioretention is a typical low impact development (LID) practice that helps reduce peak urban stormwater runoff and runoff pollutant concentrations (e.g., heavy metals, suspended solids, organic pollutants), which has become an important part of urban stormwater management over the past 15 years. To understand the research hotspots and frontiers in the field of bioretention facility research and provide a reference for research into bioretention facilities, we conduct a statistical analysis of global bioretention literature published during 2007-2021 using the Web of Science core database and the data visualization and analysis software VOSviewer and HistCite. The number of published articles related to bioretention facilities shows a rising trend over the study period, with research from China contributing greatly to global research on bioretention facilities. However, the influence of articles needs to be increased. Recent studies mainly focus on the hydrologic effect and water purification effect of bioretention facilities and on the removal of nitrogen and phosphorus nutrients from runoff rainwater. Further studies should focus on the interaction of fillers, microorganisms, and plants in bioretention facilities and its impact on the migration, transformation, and concentrations of nitrogen and phosphorus; the purification effect and mechanism of specific emerging contaminants in runoff; the selection and configuration optimization of filler materials and plant species; and the optimization of the design parameters of the model for bioretention systems.
生物滞留是一种典型的低影响开发（LID）实践，有助于减少城市暴雨径流和径流污染物浓度（如重金属、悬浮物、有机污染物）峰值，在过去 15 年中已成为城市雨水管理的重要组成部分。为了了解生物滞留设施研究领域的研究热点和前沿，并为生物滞留设施的研究提供参考，我们使用 Web of Science 核心数据库和数据可视化与分析软件 VOSviewer 和 HistCite 对 2007-2021 年期间发表的全球生物滞留文献进行了统计分析。在研究期间，与生物滞留设施相关的已发表文章数量呈上升趋势，中国的研究对全球生物滞留设施研究做出了巨大贡献，但文章的影响力有待提高。最近的研究主要集中在生物滞留设施的水文效应和水质净化效应以及对雨水径流水体中氮磷营养物质的去除上。进一步的研究应侧重于生物滞留设施中填料、微生物和植物的相互作用及其对氮磷迁移、转化和浓度的影响；特定新兴污染物在径流中的净化效果和机制；填料材料和植物物种的选择和配置优化；以及生物滞留系统模型设计参数的优化。
