摘　　要：基于现场实测水文泥沙及地形资料,研究了岱山北侧海域的水沙环境及海岸演变特征。研究结果表明:研究海域属典型的淤泥质海岸,水深条件好,波流动力总体较强、水体含沙量较高,底质泥沙颗粒较细,泥沙来源较为丰富;研究海域近期受围填海等人为活动影响,海岸线大幅向海推进,近岸浅滩区域出现了大幅度的淤积,深槽区域出现了较大幅度的冲刷;在该区域进行人为工程应尽量避免较大幅度地改变当地的水动力条件,避免对海洋环境产生不利影响。Based on the measured hydrological and topographic data at north of Daishan Island,the hydrodynamic and sedimentary environment and coastal evolution characteristics were analyzed in this paper.The main research conclusions are showed as follows:the study area is a typical muddy coast,with good water depth conditions,strong wave and current dynamics,high sediment content,fine bed sediment and rich sediment sources;affected by human activities such as reclamation,the coastline of the study area has been greatly pushed out,and seabed at the shoal area experienced a significant siltation process and that at the deep area experienced a significant scouring process;in all,when man-made engineering should be done in this area,great changes in local hydrodynamic conditions shall be avoided as far as possible,otherwise it will have an adverse impact on the marine environment.
