| 摘 要： | 根据大比例尺地形测量数据,采用GIS技术对洋山港堵汊工程前后周边海底冲淤变化进行了初步分析.结果表明:工程建设前(1998～2004年),洋山港域的冲蚀速率大于外围海域.工程建设后的2004和2005年,洋山港域的平均刷深幅度明显小于外围海域;2005和2006年,洋山港域出现显著淤积(平均淤厚度0.29 m),而外围海域仍维持冲蚀状态.主要原因为建港期间的系列堵汊工程在一定程度上削弱了港域内的动力条件,导致冲蚀减弱并出现一定的淤积.

| Abstract: | This paper analyses the erosion-accretion change before and after the plugging offshoot project at Yangshan Harbor.To do this work,large scale topographic maps were used and GIS was adopted.The results show: before the project(19982004),the erosion of the sea area within Yangshan Harbor is stronger than that of the periphery around the harbor.After the project,the average depth of erosion within Yangshan Harbor was evidently less than that of the periphery between 2004 and 2005.It turned to accumulate at th... |
