河渠或沟道植树是利用生物措施来治理泥沙的一种有效方法 ,河渠或沟道植树又称为植物“柔性坝”。本研究通过室内水槽模型试验 ,探讨了植物“柔性坝”的布置方式、种植密度对河渠水流的影响。由实验得出 ,植物“柔性坝”可以起到阻缓水流、拦截泥沙的作用 ,并且植物“柔性坝”的种植密度和坝长不同 ,阻水作用亦不同。试验表明 ,坝长的阻水作用较坝的密度要大得多
Planting trees in canals or channels is an effective method of harnessing biological measures to manage sediment. River canals or trenches are also called plant “flexible dams.” In this study, the model experiment of indoor sink was carried out to discuss the effect of plant “flexible dam” arrangement and planting density on river flow. The experiment shows that plant “flexible dam” can play a role of blocking water flow and intercepting sediment, and planting density and dam length of plant “flexible dam” are different, and water blocking effect is also different. Tests show that the dam length of the water blocking effect is much greater than the density of the dam
