摘要
为了测定长江口外海域悬沙浓度,根据2006年8月观测数据,以设定的反映悬沙分布特性的指标变量——悬沙特征系数为基础,根据得出的分析结果测算出来不同的悬沙垂直分布结果,并与实际观测的悬沙浓度进行对比.通过完善提出的悬沙浓度垂向悬沙浓度剖面实用模型,根据实际资料反映出来的数据验证模型的正确性和有效性,从而为由海表悬沙浓度推测水下悬沙浓度奠定基础.
Based on the observation data of suspended sediment concentration （SSC） collected in the areas adjacent to the Changjiang Estuary in August, 2006, this paper proposed an index, the Characteristic Coefficient of SSC （CCoSSC） , to describe the suspended sediment properties. CCoSSC shows that there are two kinds of distribution types near the Changjiang Estuary. The practical model of CCoSSC was built and tested by observation data. Therefore, the possibility to reproduce the profile of SSC for the application surface SSC by satellite remote sensing is provided.
