摘要
西洋水道是江苏岸外海底沙脊群内一条涨落潮流速大、宽深直的潮流通道.本文在野外调查获得第一手资料的基础上分析了其水文泥沙特征,利用GIS方法分析了其近30多年来的地形演变特征.得出的结论认为,西洋水道从60年代到90年代不断冲宽刷深,目前基本上处于冲淤动态平衡状态或微冲状态,是一条稳定的潮流通道.
Xiyang Channel, wide-and straight-formed, is a tidal channel in the sand ridges, offshore of Jiangsu Province, in the Yellow Sea, through which flood and ebb tidal flow is strong. Based on in situ investigation, the dynamic and material features of the channel are analysed. The morphologic variations for over thirty years past are approached using GIS method. It is concluded that the channel is under the stable conditions.
