摘　　要：Roadside green swales have emerged as popular stormwater management infrastructure in urban areas,serving to mitigate stormwater pollution and reduce urban surface water discharge.However,there is a limited understanding of the various types,structures,and functions of swales,as well as the potential challenges they may face in the future.In recent years,China has witnessed a surge in the adoption of roadside green swales,especially as part of the prestigious Sponge City Program(SCP).These green swales play a crucial role in controlling stormwater pollution and conserving urban water resources by effectively removing runoff pollutants,including suspended solids,nitrogen,and phosphorus.This review critically examines recent research findings,identifies key knowledge gaps,and presents future recommendations for designing green swales for effective stormwater management,with a particular emphasis on ongoing major Chinese infrastructure projects.Despite the growing global interest in bioswales and their significance in urban development,China's current classification of such features lacks a clear definition or specific consideration of bioswales.Furthermore,policymakers have often underestimated the adverse environmental effects of road networks,as reflected in existing laws and planning documents.This review argues that the construction and maintenance of roadside green swales should be primarily based on three critical factors:Wellthought-out road planning,suitable construction conditions,and sustainable long-term funding.The integration of quantitative environmental standards into road planning is essential to effectively address the challenge of pollution from rainfall runoff.To combat pollution associated with roads,a comprehensive assessment of potential pollution loadings should be carried out,guiding the appropriate design and construction of green swales,with a particular focus on addressing the phenomenon of first flush.One of the major challenges faced in sustaining funds for ongoing maintenance after swa
