摘要
利用2002、2005、2010年石岛湾沿岸海图资料,对0m等深线位置的变化进行了对比,计算了0m等深线变化速率,分别模拟和描绘了赤山宾馆-留口大桥-黄海造船厂岸段的岸线变化,分析了岸线演变致因。研究结果表明,石岛湾研究岸段的侵蚀情况严重,部分岸段存在冲淤情况,自然因素和人类活动因素不同程度地加速了石岛湾海岸侵蚀。
By means of studying the 0 misobaths on the sea charts(2002,2005,2010),compared 0 mbathymetric position change,calculated the change rate of 0 misobaths,the shoreline variation of the Chishan Hotel-the bridge-huanghai shipyard Bank segment are respectively simulated,and shoreline evolution causes are analyzed.The results showed that the coastal erosion circumstances along the Shidao Bay serious,there are a part of bank erosion and deposition.Natural factors and human activities factors accelerate Shidao Bay coastal erosion to varying degrees.
