摘要
Abstract
Based on surficial samples,depth data and Landsat remote sensing images,the characteristics of surface sediment,shoreline change,and scouring and silting pattern have been studied in the offshore area up to the 8 m of isobath from the Sanshan Island to Haibeizui.Results show that there are 4 types of surface sediment in the study area,i.e.sandy silt,silty sand,pebbly sand and sand.Shoreline is retreating in the whole region.The retreating rate from the Sanshan Island to Haibeizui is 2.5m/a in 1995-2005,and 2 m/a in 2005-2015.The retreating rate of shoreline from Haibeizui to Shihuzui is 2.5 m/a during 1995-2005,and 3.5 m/a during 2005-2015.The study area is under erosion during the period of 2004～2015.Due to the effect of offshore construction programs,the bay to the southwest of Haibeizui cape is under deposition during the period of 2004-2007.It turned to erosion from 2007 to 2015;the west of Haibeizui from 300 m to 1 200 m in width is under an erosion state during 2004-2007,and became deposition during 2007-2015.Wave is the dominant factor of erosion and deposition.Human activities,such as offshore constructions,have played significant roles.关键词
