山东半岛近岸海区全新世泥质沉积体研究现状

20世纪80年代以来，山东半岛近岸海区全新世泥质沉积体引起了地学界的关注，很多学者对其进行过研究并发表了众多相关论文。综合前人的研究成果认为，山东半岛全新世泥质沉积体受到黄海暖流和黄海沿岸流的共同作用，呈现出中间厚、向海向陆减薄的楔形，并沿山东半岛发育，其物质来源主要是黄河注入所带来的沉积物；在形成机制上，受到海平面上升、潮流和黄河入海口的迁移等多种因素的控制，成因复杂；在形成时间上，现今的研究成果普遍认为该泥楔形成于全新世冰后期海平面上升时期。对目前研究中仍存在的问题进行讨论，提出了山东泥楔的未来研究方向，指出应该建立多种水动力耦合作用下的泥沙输运与沉积模式，着重从海洋沉积动力学角度进行新的研究。

A REVIEW OF THE SEDIMENTATION OF THE HOLOCENE CLINOFORM OFF SHANDONG PENINSULA

Since the 1980s, the Holocene clinoform or the mud wedge around the Shandong Peninsula has raised great attention from marine geologists, and many papers have been devoted to this topic. In this paper, we made a review of the previous research results and published papers. The prevailing o- pinion believes that the wedge-like sedimentary body, which is thicker in the middle and becomes thin- ner on the two sides towards the land and sea, is formed under the interaction of the yellow sea warm current and the yellow sea coastal current around the Shandong peninsula. The sediments are mainly from the Yellow River. The formation mechanism of the deposits involves many factors, such as the tide, sea level rising and the shifting of the Yellow River mouth. It was formed in the period o{ Late Holocene deglaciation when the sea level was rising. We also discussed the problems remained. It is suggested that further researches should pay more attention to the marine sediment dynamics, and the transportation and sedimentation of the fine sediments under the hydrodynamic regime.
