摘要
概括了长江口河口湿地的特征以及影响因素,应用验证良好的FVCOM建立大范围的三维潮流数值模型,分析海平面上升对湿地面积和潮流垂向结构的影响,在各种地形条件、水力边界和计算参数都一致的条件下,模拟了平均海平面抬升0.5 m情况下长江口地区湿地面积、潮流垂向结构的变化。
The characteristics and influencing factors of the estuary wetland of the Yangtze Estuary are sum - marized in this paper. The three -dimensional tidal current numerical model is established by using the FVCOM model, which includes the large scale of the Yangtze Estuary, the Hangzhou Bay and the adjacent sea area. Analysis of the influence of sea level rise on the vertical structure of wetland area and tidal current. Under the same topography, boundary and computing param - eter, the change of estuarine wetlands and vertical distribution of tidal current is simulated after sea level rising 0.5 meter.
