摘    要:胶州湾属基岩海湾型潮汐通道,湾口内、外发育较为典型的涨、落潮流三角洲,地貌体系较为完整。总的说来,胶州湾涨潮流占优势,但涨、落潮优势流路平面分异明显:落潮流三角洲中央以落潮优势流为主,两侧涨潮流占优势;涨潮流三角洲中部以涨潮优势流为主,两侧落潮流占优势,涨、落潮优势流在内、外汊道口之间发生交叉。由于水流的非正向入射,潮汐通道地貌体系不对称,潮流三角洲在湾内东侧发育、在湾外东北侧发育。

关 键 词:潮汐通道  地貌体系  涨、落潮优势流

Abstract:The Jiaozhou Bay is a tidal inlet of bedrock bay type, the typical flood and ebb tidal deltas are developed inside and outside the bay mouth, and the geomorphologic system in the bay is complete. Generally peaking, the flood current is dominant in the Jiaozhou Bay, there is an obvious horizontal differentiation between flood-dominated and ebb-dominated flow paths, and the geomorphologic system in the tidal inlet is controlled by the tidal current. The ebb-dominated current is dominant in the central ebb tidal delta, and the flood-dominated currents are dominant on both sides of the ebb-dominated current; the flood-dominated current is dominant in the central flood tidal delta, the ebb-dominated currents are dominant on both sides of the flood-dominated current, and the flood-dominated current and ebb-dominated current cross between the inner bay mouth and the outer bay mouth. The obliquely inflowing current forms an asymmetric geomorphologic system in the tidal inlet, the tidal deltas are more developed on the east side of inner bay and on the northeast side of outer bay.
Keywords:tidal inlet  geomorphologic system  flood- and ebb-dominated currents
