自然地理朝鲜陆缘海,包括黄海东部在内,其面积约为500000平方千米。济州岛与对马岛之间的浅海区称为朝鲜南海。黄海的特征为宽阔、平坦、海底地形变化不大,平均水深约55米(最大水深不超过100米)。黄海东部分布着许多岛屿,沿岸绵延着潮坪,水深小于70米处有许多与海岸线斜交的潮成沙脊。海底在东部三分之二处逐渐增深。陆架海底向东南加深成为冲绳海槽向北的延伸部分。海底岩石露头仅见于朝鲜半岛之西济州岛向海延伸不远处,以及济州岛西南的索科特拉岩。济州岛周围的海底较深,超过100米。
Natural geography North Korea Luyuan Sea, including the eastern part of the Yellow Sea, including an area of about 500000 square kilometers. The shallow sea between Jeju Island and the Falklands is called the South China Sea. Yellow Sea is characterized by wide, flat, small changes in seabed terrain, the average depth of about 55 meters (maximum depth of not more than 100 meters). There are many islands in the eastern part of the Yellow Sea, with tidal flats extending along the coast. There are many tidal sand ridges crossed with the coastline at depths of less than 70 meters. Seabed gradually deepened in two thirds of the east. The deepening of the shelf seabed to the southeast became an extension of the northward extension of the Okinawa Trough. Seabed rock outcrops are found only a short stretch of sea to the west of Jeju Island in the Korean Peninsula and Socotra Rocks to the southwest of Jeju Island. The seabed around Jeju Island is deeper, more than 100 meters.
