| 摘 要： | 水中悬浮固体会影响沉水植物正常的生长，沉水植物反过来也会影响水中悬浮固体的浓度和沉降。实验研究了两种典型的沉水植物——轮叶黑藻和亚洲苦草在静止水体中对悬浮固体的作用，并与空白组进行了比较。结果表明：轮叶黑藻在一定条件下可明显降低水中悬浮固体的浓度，亚洲苦草则效果较差，另外沉水植物的种植都可以有效降低底部沉积物的量。 |

| Abstract: | Suspended solid in the Water will affect the normal growth of submerged plants, in turn, submerged plants will affect the concentration of suspended solid and it's settlement in the water. The experiment has studied the effect of two submerged plants -- Hydrilla verticillata and Vallisneria spiralis to suspended solid in static water and compared them with the blank cell. The result indicates that Hydrilla verticillata can significantly reduce the concentration of suspended sediment in the water under certain conditions,at the same time can reduce the sediment settlement in the bottom. But Vallisneria spiralis has seldom helpful impaction. |
