| 摘 要： | 该文主要介绍了潮流对沉积作用的影响，沉积物的再悬浮和最大浑浊带的形成机制以及影响沉积物絮凝沉降的因素。潮流是搬运河口泥沙的主要动力，沉积在河口拦门沙的泥沙会在潮流的作用下向河口外继续搬运。沉积物的再悬浮和最大浑浊带密不可分，正是由于沉积物在周期性潮流的作用下引起再悬浮，为最大浑浊带的形成提供了条件。影响沉积物絮凝沉降的因素很多，有内因，也有外因。内因是颗粒物自身的性质；外因如盐度、流速、pH值等。

| Abstract: | The paper mainly discusses the effect of the tide on the sediment, the resupension, the formative mechanism of the turbidity maximum zone, and factors that affec the coagulation and sedimentation of the sediment. The tide is the main power that carries the sand of the estuary. The sand that settles on the estuary will be unceasingly carried outside the estuary by the tide. The resuspension of the sediment is connected with the turbidity maximum zone. It is the resuspension of the sediment caused by the seasonal tide that offers the formative condition of the turbidity maximum zone. The factors that affect coagulation and sedimentation of the sediment are many, including extrinsic factors and intrinsic factors such as salinity, velocity of flow and pH. |
