| 摘 要： | 洋山深水港区是由大、小洋山南、北两支岛链组成,形成东窄西宽面向杭州湾开口的喇叭状水域,文章结合洋山港建设以来现场实测水文、地形资料,分析了1998～2007年洋山海域通道内地形冲淤演变情况,将洋山港通道内地形变化特征概括为:随着边界的变化,地形冲淤调整迅速;南北格局呈现出"南淤北冲"的规律;长时间尺度来看,近期地形总体趋于相对平衡,略有冲刷;短时间上看,年内冲淤变化大。为洋山港港区进一步的规划方案论证提供基本依据。

| Abstract: | Yangshan Deepwater Harbor lies in the Qiqu archipelago,which is located about 32 kilometer northwest to Luchaogang harbor in Nanhui district.The sea area is composed of south and north island chains.Based on the observation data of suspended sediment concentration and landform data from 1998 to 2007,the characteristics of landform change in the channel of Yangshan sea area are analysed.The results show that the change of landform is rapid along with the boundary change;it is obvious that the south area of c... |
