舟山海域岛屿星罗棋布、汊道众多、流态复杂。采用河口海岸数值模型（MIKE 21）及全球潮波模型（TPXO.6）对舟山本岛南部海域的潮流场进行模拟。应用该模型分析连岛围涂和边滩围涂对边海域的潮流、潮量的影响，结合经验公式分析海域的冲淤变化，结果表明连岛围涂改变了汊道之间水流交换，较大幅度改变流态，而边滩围涂虽减少进潮量，却使主流外挑，对周边影响较小。
舟山海域島嶼星囉棋佈、汊道衆多、流態複雜。採用河口海岸數值模型（MIKE 21）及全毬潮波模型（TPXO.6）對舟山本島南部海域的潮流場進行模擬。應用該模型分析連島圍塗和邊灘圍塗對邊海域的潮流、潮量的影響，結閤經驗公式分析海域的遲淤變化，結果錶明連島圍塗改變瞭汊道之間水流交換，較大幅度改變流態，而邊灘圍塗雖減少進潮量，卻使主流外挑，對週邊影響較小。

Dotted with islands , Zhoushan sea area has many braided channels and complex flow pattern . In this paper , an estuarine and coastal numerical model (MIKE21 ) and a global tidal wave model (TPXO.6 ) was adopted to simulate the tidal current field of the southern waters of Zhoushan Island.The model was used to analyze the impact of tied island reclamation and beach reclamation on the tide and tidal volume of edge -to -edge waters . Empirical formula was combined with the model to analyze the sea scouring - erosion variation . Results show that tied island reclamation changed the water exchange between channels and changed the flow pattern significantly , while the side beach reclamation reduced tidal volume , but kept the mainstream outward , exerting a smaller effect on the surrounding .
