连云港近岸海域沉积物粒度端元模型分析

End-member Modeling Analysis of Sediment Grain Size in Lianyungang Coastal Area

为了研究连云港近岸海域沉积物粒度中所蕴涵的沉积信息,利用端元分析模型对连云港近岸海域108个沉积物样品粒度数据进行了反演。结果表明,连云港近岸海域沉积物分布区存在着3个具有一定动力意义的粒级组,代表了不同能量环境下形成的沉积物,并初步探讨了沉积物来源及其演变,这些结果对进一步研究连云港近岸海域沉积环境具有重要意义。

In order to obtain the sediment information of the grain size in Lianyungang Coastal Area, 108 grain size samples were studied by End-member Modeling. Results show that three dynamic populations representing different energy environment sediments exist in Lianyungang Coastal area. Besides, the source and evolution of these sediments are discussed. Such a study is of great significance for researches on the sediment environment in the area under discussion.
