| 摘 要： | 控制着辽河口海区悬浮体运移的主要动力是河流迳流、潮流和余流．它们对最大浑浊带中河水与海水的混合，密度流循环以及悬浮物的沉降和运移共同起作用．悬浮物向海运移与河口区最大浑浊带有关，即与河流迳流、潮流和余流作用所控制的悬浮物数量有关。悬浮物向海运移似乎遵循两个周期：１．小潮—大湖周期；２．河流迳流丰枯周期．最大运移发生在大潮期和河流迳流丰水期。

| Abstract: | The river flow, tides and residual flow are the main dynamics controlling suspended sediment transport and dispersion in and out of the Liaohe estuary. They combine to control mixing of river and sea water, density current circulation and the trapping of suspended sediments in the turbidity maximum. Seaward transport of sediments is related to the position of the maximum in the estuary, which is a function of river flow and the amount of sediments in suspension. This seaward transport seems to follow two cycles: (1) a neap-spring tidal cycle, and (2) a seasonal river flow cycle. The maximum transport occurs during spring tides and high river flow. |
