| 摘 要： | 舟山群岛海域潮能丰富,近年来大面积的围垦工程影响了邻近海域的潮流结构与潮能分布特征。基于FVCOM(finite volume coastal ocean model)三维水动力数值模型,选取1984年、2010年、2019年三个代表年份,探讨围垦工程影响下舟山群岛海域潮流结构与潮能分布的时空变化状况。结果显示:1984年至2010年间围垦面积相对不大,且较为分散,主要改变外海进入杭州湾各通道的潮能分配,对能量耗散的影响较小。2010年至2019年间的围垦工程缩窄了潮汐通道,流速增大使得螺头水道及邻近水道的潮能增加,近底流速增大与较强湍流涡旋的产生,使得围垦工程周边海域能量耗散更为集中。

| Abstract: | Tidal flow structures and tidal energy in Zhoushan Archipelago sea area are impacted by the land reclamation nearby. The spatial and temporal changes of the tidal flow structure and tidal energy distribution due to land reclamation in Zhoushan Islands were examined using the FVCOM (finite volume coastal ocean model). The results show that from 1984 to 2010, the reclamation area was relatively small, and which mainly changed the tidal energy distribution of the channels from the open sea to Hangzhou Bay, and had little effect on the energy dissipation. From 2010 to 2019, the reclamation projects narrowed tidal channels greatly and the spatial distribution of tidal energy flux in Luotou waterway, and its adjacent waterways was significantly increased. The increase of the near bottom velocity and the generation of strong turbulence vortex made the energy dissipation more concentrated around the reclamation project. |
