上海市南汇东滩水域位于长江口和杭州湾交汇处，受径流、潮流、波浪等综合因素的影响，该水域水流挟沙力计算比较复杂。为了确定适用于南汇东滩水域的水流挟沙力计算公式，比较分析了河口区域常用的挟沙力计算公式，选取统计拟合方法、张瑞瑾挟沙力公式以及邓家泉挟沙力公式，分不同潮期，采用实测资料进行分析拟合验证。结果表明，邓家泉挟沙力计算公式较适宜该水域水流挟沙力计算。
上海市南彙東灘水域位于長江口和杭州灣交彙處，受徑流、潮流、波浪等綜閤因素的影響，該水域水流挾沙力計算比較複雜。為瞭確定適用于南彙東灘水域的水流挾沙力計算公式，比較分析瞭河口區域常用的挾沙力計算公式，選取統計擬閤方法、張瑞瑾挾沙力公式以及鄧傢泉挾沙力公式，分不同潮期，採用實測資料進行分析擬閤驗證。結果錶明，鄧傢泉挾沙力計算公式較適宜該水域水流挾沙力計算。

The water zone of Nanhui East Shoal in Shanghai City is sited at the intersection of Yangtze River Estuary and Hang-zhou Bay. Influenced by comprehensive factors of runoff, tide flow and wave etc. , the calculation for flow sediment-laden ca-pacity in the water zone is complicated. In order to determine the flow sediment-laden capacity formula suitable for the water zone, we analyze and compare the common-used flow sediment-laden capacity formulas for estuary area and select the statisti-cal fitting method, Zhangruijin Formula and Dengjiaquan Formula for flow sediment-laden capacity to carry out analysis-fitting and verification of the suitability of the formulas in different tide periods by the measured data in the water zone. The analysis and verification result shows that Dengjiaquan Formula is more suitable for calculation of flow sediment-laden capacity in the water zone of Nanhui East Shoal.
