摘　　要：岸边布置植物柔性坝是促使河势稳定、生态修复的有效措施。通过室内模型试验,探讨了在岸边布置不同排列方式的挺水植物对水流的影响。结果表明,植物柔性坝对植物坝体段和植物坝后段的水流具有明显的阻水作用,且阻水效果随挺水植物的布置方式不同而不同;长度为1/3河道宽的单侧布置的植物坝仅对植物坝一侧河岸起到稳定水流作用,而双侧布置的植物坝则能够在阻水效果相近的情况下起到保护两岸的作用。Shore plant flexible dam is an effective measure to stable regime and ecological remediation. In this article, the impact of different arrangement of emerged plants in the shore on the water flow is discussed through indoor model test. The results show that the plant flexible dam has water-blocking effect mainly on segments of dam body and dam back; different arrangements have different resistance range of water flow; unilateral arrangement of plant dam with length of 1/3 river width only can stable water flow on the plant dam side of the river, whereas bilateral arrangement of plant dam can protect both sides of river bank in the case of similar water-blocking effect.
