生物滞留系统作为城市环境中雨水管理的一种更自然的方法，已经获得了相当大的普及。生物滞留介质的选择经常被认为是对系统性能具有最终影响的关键设计参数之一。本次审查的目标是突出的数据，挑战媒体的重要性作为主导的设计参数，并认为，长期的性能是由媒体和生物滞留系统，特别是植被的活的组成部分之间的相互作用。一些关键的相互作用与植物根系对介质孔隙结构的影响有关，这对渗透、储存能力和处理有影响。另一个相关的相互作用涉及蒸散以及对生物滞留系统的水平衡和水质性能的相关影响。植被对媒体的影响突出和实际的，以及潜在的，植物介质相互作用对生物滞留性能的影响。
Bioretention systems have gained considerable popularity as a more natural approach to stormwater management in urban environments. The choice of bioretention media is frequently cited as one of the critical design parameters with the ultimate impact on the performance of the system. The goal of this review is to highlight data that challenge the importance of media as being the dominant design parameter and argue that the long-term performance is shaped by the interactions between media and the living components of a bioretention system, especially vegetation. Some of the key interactions are related to the impact of plant roots on media pore structure, which has implications on infiltration, storage capacity, and treatment. Another relevant interaction pertains to evapotranspiration and the associated impacts on the water balance and the water quality performance of bioretention systems. The impacts of vegetation on the media are highlighted and actual, as well as potential, impacts of plant-media interactions on bioretention performance are presented.
