摘　　要：在分析、归纳前人对杭州湾流场研究成果的基础上 ,本文采用包含钱塘江河口、长江口及舟山群岛海域在内的大范围 ( 3 5 0 0 0km2 )数学模型 ,模拟 1981年夏季和 1983年冬季全国海岸带调查的大范围同步实测流场。在良好验证的基础上 ,就杭州湾入射潮波流路、涨落潮流矢分布、等潮位线、余流、盐度分布及无质量标记点迹线追踪等方面 ,分析、探讨杭州湾流场特性。成果可为更合理地规划整治。Based on analysis and induction of predecessor’s study results for flow field of Hangzhou Bay, the field survey data for Hangzhou Bay during the summer and winter have been verified well by means of the EU-FEM mathematical model. The characteristic of flow field of Hangzhou Bay has been analyzed and studied in respects of the flow path, velocity patterns, isograms of tide level, residual flow and salinity. The study results can be used as an important reference in the plan, development and utilization of Hangzhou Bay.
