    梅山港水道的冲淤演变

    SCOUR AND SILTING HISTORY OF MEISHANGANG CHANNEL

    • 摘要: 梅山港水道位于杭州湾以南、舟山群岛西侧的穿山半岛与梅山岛之间,是象山港口北岸沿岸小型潮流通道。根据历史资料,对梅山港水道岸线变迁、滩槽变化、纵剖面变化、横断面以及区域冲淤变化等进行了定量的研究。结合实测水文泥沙、地貌形态、沉积、人类开发活动等资料进行综合分析后认为:梅山港水道平面形态轮廓深受沿岸历史围涂筑塘的影响;梅山港水道整体上处于缓慢淤积的趋势;水道平面形态和泥沙运移特征具有涨潮槽的特性;七姓涂围涂工程等人类活动可能加剧梅山港水道的淤积过程。

       

      Abstract: The Meishangang Channel is located between Chuanshan Peninsula and Meishan Island in the south of Hangzhou Bay to the west of Zhoushan Archipelago. It is a small tidal channel at the north bank of the Xiangshan Harbor entrance. Based on historical data, we studied coastline changes, shoal and channel changes, longitudinal profile changes, cross-sections changes and regional erosion and deposition patterns in this paper. An integrated analysis was made with the data of the observed tidal current, suspended sediment load, geomorphology, deposition, and human activities. Our study reveals that the morphology of the Meishangang Channel is deeply affected by land reclamation and dam building, and it is in a slow sedimentation trend as a whole. The Channel, according to its plane form and sediment transport, is a kind of flooding channel. The Qixingtu Reclamation Project will speed up the siltation within the Meishangang Channel.
