Soil degradation by concentrated runoff and soil erosion induces major environmental and economic damages, notably in agricultural areas under temperate climates. The use of herbaceous vegetation aims to increase the hydraulic resistance and thus reduce runoff and soil erosion while retaining sediments on site. However, the identification of the most suitable species to mitigate runoff is often specific to a phytogeographical territory and hampered by the intraspecific variability, which reduces the transposition of a solution to other territories and the ability to quantify the effects of the vegetation. Using a plant trait‐based approach allows understanding and characterising the direct effects of the vegetation on runoff and soil erosion mitigation as well as on the sediment retention increase. Here, we review the influence of plant aboveground functional types and traits of herbaceous vegetation on the hydraulic resistance and sediment retention and the contentious effects of the functional diversity on the hydraulic resistance and sediment retention, within agricultural catchments. Using this knowledge, we propose applications of the trait‐based approach to design and manage herbaceous hedges for sediment retention and soil erosion control. This review synthesises recent advances regarding the effects of the functional traits on runoff and sediment retention and defines a trait‐based selection method of the plant species for runoff and soil erosion control.

农业流域基于草木的基于性状的沉积物截留和径流控制：综述

集中的径流和水土流失对土壤造成严重的环境和经济损害，特别是在温带气候下的农业地区。草本植物的使用旨在增加水力阻力，从而减少径流和土壤侵蚀，同时保留沉积物。但是，确定最合适的物种以减轻径流通常是特定于植物地理区域的，并且受到种内变异性的阻碍，这减少了溶液向其他区域的迁移以及量化植被影响的能力。使用基于植物特征的方法可以了解和表征植被对径流和水土流失缓解以及对沉积物保留量增加的直接影响。这里，我们回顾了农业流域植物地上功能类型和草本植物性状对水力阻力和沉积物保持的影响以及功能多样性对水力阻力和沉积物保持的竞争作用。利用这些知识，我们建议应用基于特征的方法来设计和管理用于保护沉积物和控制土壤侵蚀的草本篱笆。这篇综述总结了有关功能性状对径流和沉积物滞留的影响的最新进展，并定义了基于性状的植物种类选择方法，用于径流和土壤侵蚀控制。
