| Abstract: |
| Sediment distribution is important for morphodynamic evolution and shoreline changes in coastal zones and estuaries. In the study, the data of 230 surface sediment samples collected from the Xiamen Bay sea area in September 2008 are used to investigate the spatial distribution and sediment transport pathway. The grain size distribution of surficial sediments in the Xiamen Bay area is shown distinctly in this study. In addition, the Grain Size Transport Analysis model is used for conveying trend analysis of the sediment in this area, particularly for determining the sediment movement trend. The results indicate that eight sediment types are present for samples, with clayey silt comprising the highest percentage in the study area at 65.22%. Moreover, in the different subareas, the characteristics of grain size parameters are obviously different owing to different sediment sources and hydrodynamic conditions. Furthermore, runoff, tides, and waves are the main forces dominating sediment dynamics on the seabed and tidal flats, and the sediment movement trend is closely related to hydrodynamic conditions. |

| 沉积物分布对河口海岸地区的地貌演变和岸线变化非常重要。本文收集了2008年9月厦门湾海域的230个表层沉积物样品的数据,研究其表层沉积物空间分布和运输特征。厦门湾海域表沉积物的粒度分布特征非常明显。同时在应用GSTA模型对沉积物进行输运趋势分析的基础上探讨该区域泥沙运移趋势。结果表明,该海域有八种沉积物类型,粘土质粉砂占有比例最高,为65.22%;而且在不同的分区,由于不同的沉积物源和水动力条件,粒度参数特征也有所不同。径流、潮汐和波浪是海床表层沉积物、滩涂变化的主要控制动力,泥沙运动趋势与水动力条件密切相关。 |
