| 摘 要： | 通过对辽东湾北部浅海区现代沉积基本特征分析,认为该区现代沉积类型有8种,以粉砂和粘土分布最广。双台子河以东地区水动力较西部活跃,现代垂向堆积速率,双台子河以西地区高于以东地区,近岸高于水下;沉积物向海横向推进速度,双台子河以西地区快于以东地区。

| Abstract: | Based on recent materials from our geological survey in the north shallow region of the Liaodong Bay during 1988-1989, the following sedimentation features have been found: (1) Average transportation rate of sediments from coastline to sea is 20m a year and the rate in the west is larger than that in the east of this region. (2) Sedimentation rate is about 2cm a year on the average and the rate in the west is also larger than that in the east. (3) Grain size of sediments is coarser in the east than in the west. Therefore, it can be thought that hydrodynamic energy is larger in the east than in the west in this region. |
