摘要
本文以丁字湾等基岩海湾为例，论述了黄渤海沿岸海湾－溺谷型潮汐汉道的地貌结构，尤其着重于口门段深槽及涨、落潮三角洲。认为涨、落潮三角洲的发育状况与入湾河流的供沙量、纳潮水域容量、被浪作用、潮差以及口少卜海域的开阔程度有关；泻湖型潮汐汉道的落潮三角洲的典型模式可以应用于海湾－溺谷型潮汐汉道，但涨潮三角洲因受基岩海湾的复杂岸线的限制而不能充分发育。本文还讨论了海湾型潮汐汉道与半开敞海湾在动力和形态中的差异。
This article analyses the Seomorphology of bsy and drowned-valley type tidal inlet along the Huanshai and Bobal Seas' coasts with reference to the Dinzoiwan my and the like, particularly that of their estuary flood and ebb-tidal delay.The authors consider that the development of the deltas is related to tidal range, wave conditions, Sediment amount flowing into the bays, bsy volume and unenclosure of sea waters off their gorse. The reanrch Shows the standard pattern of ebb-tidal delay of lagoonal-type tidal inlet,wnich is proposed by Hayes and et al,can be applicable to the hay and drowned-valley type inlet,but the flood-tidsl delay cannot fully develop because it is limited by the complicated shoreline of the rocky bay.The poper also discusses the differences between the bay and drowned-vally type tidal inlet and semi-open bay in seomorphology and dynamics.
