摘　　要：以湛江金沙湾海滩养护前后不同时期沉积物粒度监测数据、海底高程扫描数据和遥感影像为依据,运用Arc GIS 3D Analyst进行沉积物和海底地形分析,得出湛江市金沙湾海滩养护工程实施前后不同时期海底沉积物、地形表面和动态剖面变化情况。结果表明,湛江金沙湾海滩侵蚀区域集中在风车广场对出海域和原红嘴鸥码头附近,后期应重点考虑对此区域进行修复重建。Based on sediment granularity monitoring data,seabed elevation scanning data,and remote sensing images of the Jinshawan beach in Zhanjiang before and after nourishment,the sediments and seabed topographies were analyzed using ArcGIS 3D Analyst.And then,the changes of the seabed sediments,topography surface and dynamic profile of the beach were analyzed.The results show that the eroded area of the Jinshawan beach focus on the waters back on Windmill Square and near the old Hongzuiou Dock,and it is should be emphasized the restoration work for the eroded area.
