几十年来，河岸带一直用于地下水流中 NO 和地表流中总 P (TP)、沉积物和农药的水质管理。直到最近，人们才在河岸地区对可溶性活性磷 (SRP)、汞、新兴污染物和温室气体 (GHG) 通量（NO、CO 和 CH）的归宿和迁移进行了研究。总体而言，河岸带能够有效地减少地下流中新出现的污染物，并且只有在富含汞的湿有机土壤占主导地位时，才能成为景观中甲基汞生产的热点。然而，河岸地区在 SRP 去除或温室气体排放方面并没有提供一致的效益。尽管大多数现有的河岸模型几乎完全专注于 NO 去除，但河岸模型的最新发展表明，使用易于访问的数字环境数据集来模拟和扩展除 NO 去除之外的河岸功能的潜力，包括 SRP、TP 和 GHG 动态。为了进一步为流域综合管理工作提供信息，应该对各种做法（包括河流恢复、地下排水、两级沟渠、海狸坝类似物、反硝化生物反应器和渗透性反应屏障、人工湿地和短期林业作物）如何影响河岸水和空气质量功能进行更多研究。河岸带效益不仅应在水和空气质量方面进行讨论，还应在娱乐、野生动物栖息地和其他生态系统服务方面进行讨论。需要更多的研究来充分解决与多污染物多用途景观背景下的河岸带管理相关的潜在水质或空气质量权衡问题。
Riparian zones have been used for water quality management with respect to NO in subsurface flow and total P (TP), sediments, and pesticides in overland flow for decades. Only recently has the fate and transport of soluble reactive P (SRP), Hg, emerging contaminants, and greenhouse gas (GHG) fluxes (NO, CO, and CH) been examined in riparian zones. Overall, riparian zones are efficient at reducing emerging contaminants in subsurface flow and only function as hot spots of methylmercury production in the landscape when dominated by Hg-rich wet organic soils. However, riparian zones do not provide consistent benefits with respect to SRP removal or GHG emissions. Although most existing riparian models almost exclusively focus on NO removal, recent developments in riparian models demonstrate the potential for using easily accessible digital environmental datasets to simulate and scale up riparian functions beyond NO removal to include SRP, TP, and GHG dynamics. To further inform integrated watershed management efforts, more research should be conducted on how various practices, including stream restoration, subsurface drainage, two-stage ditches, beaver dam analogues, denitrification bioreactors and permeable reactive barriers, artificial wetlands, and short-rotation forestry crops affect riparian water and air quality functions. Riparian zone benefits should be discussed not only with respect to water and air quality, but also in terms of recreation, habitat for wildlife, and other ecosystem services. More research is needed to fully address potential water quality or air quality tradeoffs associated with riparian zone management in a multicontaminant-multiuse landscape context.
