本文依据长海群岛底质粒度资料,结合区域水动力条件对表层沉积物作了系统分析,结果显示长海群岛区可分为以下五个沉积区:粗粒沉积区(细砂区)、岛源沉积区、水道沉积区、近岸混合类型沉积区和岸边沉积区,为海域底质增养殖环境提供了基础资料。
Based on the data of sediment particle size of Changhai Islands and the hydrodynamic conditions of the region, the sediment was analyzed systematically. The results show that the Changhai Islands can be divided into five sedimentary areas: coarse sedimentary zone (fine sand zone), island source sediment Area, waterway sedimentary area, near-shore mixed type sedimentation area and bank sedimentary area, providing the basic information for the enhancement of aquaculture environment in the sea area.
