| 摘 要： | 为了解廉州湾东岸海滩修复前后海岸地形的变化规律,本文以分析沙滩测量特性为前提,对修复沙滩特定剖面进行变形监测;并运用高程-距离绘制剖面图,同时对潮下带进行水下地形测量;应用GIS建立DEM,对比等高线,还重点分析了台风对沙滩地形的影响。结果表明,修复沙滩经过2年的时间,海岸线向陆域方向移动,滩肩变窄;0 m等高线向海方向移动20 m,-0.5 m等高线向海方向移动30 m;台风对沙滩的侵蚀是直接性的,且形成垂直断面;台风过后经历0.5年时间沙滩基本处于平衡状态。

| Abstract: | For understanding before and after repairing Variation of coastal topography of the Lianzhou bay of east Coast , Based on a-nalysis of beach survey characteristics , we conduct deformation monitoring of specific beach profile and use elevation -distance to draw profiles,In order to contrasting depth contours ,we measure underwater topography in subtotal belt and build DEM Appling GIS , We also focus on the effect of typhoon on beach topography .The result showed that Repairing the beach for two years:1) the coastline moves towards the land, the coast is narrowed;2) The 0 m contour moves 20 m in the direction of the sea, -0.5 m contour moves 30 m in the direction of the sea;3) typhoon erosion of the beach is direct , vertical section of beach formed after typhoon , after the ty-phoon, the beach is basically in equilibrium for half a year . |
