| 摘 要： | 长江河口盐水入侵一直是困扰上海市工农业生产及生活用水的一个重大问题。文章通过建立"长江口—杭州湾"大范围的二维水流盐度数学模型,在验证的基础上,重点分析了长江口盐水入侵总体格局、北支盐水倒灌、南支盐度分布格局等问题,并指出由于横沙通道的涨落潮流不平衡,北槽会有部分盐水倒灌进入北港;基于数学模型,对北支倒灌盐通量进行了初步计算。

| Abstract: | Salinity intrusion in the Yangtze River Estuary is a serious problem for the industrial and agricultural production and living in Shanghai City. A 2D large scale tidal current and salinity transport model of the Yangtze River Estuary and Hangzhou Bay was developed. Based on calibration and validation, some key problems such as overall pattern of salinity intrusion in the Yangtze River Estuary, the saltwater spilling over from the north branch and salinity distribution in the south branch were analyzed. Because the flood tidal current is not equal to the ebb tidal current in Hengsha Watercourse, some saltwater can spill over from the north passage to the north channel. Salt flux from the north branch into the south branch was preliminarily analyzed by using the mathematical model. |
