最后对植物坝前上游段推移质泥沙的输移特性进行了研究，初步探明了植物“柔性坝”的固沙机理。
Lastly, studies transportation characteristic of bed load sediment of upstream end before vegetation dam. Preliminarily clear sand-binding mechanism of vegetation "flexible dam".
说明植物坝可以减小泥沙的起动拖曳力，降低上游泥沙的起动频率，并能使运动的泥沙在坝上游沉积下来。
These show that vegetation dam can reduce starting drag force and starting frequency of sediment in upper reaches. And can make athletic sediment deposit.
由试验得出，植树后底坡越大，流量对植物坝的壅水影响越不明显，即底坡对植物坝壅水的影响要比流量的影响大。
The experiment showed that the bigger the base slopes after planting trees are, the more obviously the backwater of vegetation dam the discharge influences.
