渤海三大海湾之一的莱州湾位于渤海南部,凹入山东半岛的北缘,湾口两起黄河口,东至龙口。注入莱州湾的主要河流有黄河,小清河,潍河等。我们曾对莱州湾东缘三山岛至虎头崖之间50多公里长的沿海地带进行了调查(图1),研究了此范围内沉积物的粒度、重矿物特征及变化,以便查清其物质来源和运移趋势。 Laizhou Bay, one of the three major bays in the Bohai Sea, is located in the southern Bohai Sea and recessed into the northern margin of the Shandong Peninsula. The mouth of the mouth of the Laizhou Bay is surrounded by two mouths of the Yellow River and east of Longkou. The main rivers injected into Laizhou Bay are the Yellow River, Xiaoqing River and Weihe River. We conducted a survey of more than 50 kilometers of coastal areas between Sanshandao and Hutatsu Cliffs on the eastern margin of Laizhou Bay (Figure 1) and studied the sediment grain size, heavy mineral characteristics and changes in this area in order to find out Material sources and migration trends.
