中文摘要：
通过分析钻孔和浅地层剖面资料，研究了胶州湾及青岛前海潮流沉积体系。该体系包括大沽河洋河潮控三角洲和与狭口海湾密切相关的涨、落潮流三角洲。潮流作用在各三角洲的形成过程中为主要的沉积动力。前者发育在湾西侧，形成了河口沙坝和分流间湾等沉积相；后者分布在湾口两侧，以潮道和潮流沙脊为主要特征。根据对各沉积相特征的分析，认为潮流沉积体系的演化已整体趋于稳定。
英文摘要：
Based on an analysis of drill and stratigraphy profiles, the tital depositional system in the Qingdao area is studied. The Dagu-Yanghe tidal delta, a facies system, is formed on the west side of Jiaozhou bay, where the river mouth bar and interdistributory bay are the major sub-facies. The flood-tidal delta and ebbtidal delta are in close proximity of the inlet. Tidal channel and tidal sand ridge facies is the dominant facies of the tidal-delta. The formation of the system is governed primarily by tidal-current processes. It is concludesd that the evolution of the depositional system is becoming steady, and its development depends on sealevel changes in the future.
