东海陆架的动力沉积作用(英文)

DYNAMIC SEDIMENTATION ON THE EAST CHINA SEA SHELF

本文全面地讨论了潮流、风暴和环流等动力作用对东海陆架沉积作用的影响。根据作用于陆架的主要动力营力可将陆架划分为三个动力沉积区:潮流沉积区、环流沉积区和复合沉积区。东海陆架表层沉积物与现代水动力条件处于平衡状态,因此,中、外陆架的广阔砂带应属原地现代沉积,而不是晚更新世的残留沉积。

The influence of dynamic factors, such as tidal currents, storms and circulation on the sedimentation on the East China Sea Shelf has been discussed comprehensively in the article. Based on the main dynamic agents the East China Sea Shelf can be classified into three dynamic sedimentary provinces: tidal, circulation, and compound. The surficial sediments of the East China Sea Shelf are in equilibrium with recent hydrodynamic conditions, thus, the widespread sands are of autochthonous origin, rather than the relict sediments of the late pleistocene.
