中文摘要：
中国东部陆架广泛发育潮流沙脊，其发育和演化过程是我国陆架边缘海环境演化的重要部分。西朝鲜湾潮流沙脊位于北黄海东部，属开敞型海湾沙脊，与东海陆架和江苏岸外等开阔陆架沙脊相比，具有鲜明的特色，但尚未开展实质性的研究。本项目拟选取西朝鲜湾潮流沙脊为研究对象，通过点(表层和岩芯沉积物、定点海流观测)-线(浅地层剖面)-面(多波束测深和侧扫声纳)三位一体的研究，刻画西朝鲜湾潮流沙脊的三维精细结构和海底微地貌特征，揭示其沉积动力机制；构建该海域晚第四纪以来具有年代地层格架的层序地层模式，揭示西朝鲜湾潮流沙脊的时空发育规律；阐明西朝鲜湾潮流沙脊的形成演化对海平面变化及区域"源-汇"效应的响应关系。研究成果将是开敞型海湾沙脊成因模式和演化机制的有益补充，有助于全面了解晚第四纪以来我国东部陆架的环境演化史，并为研究区工程建设、砂矿开采等提供科学依据。
