| 摘 要： | 根据2008年9月采集的九龙江口-厦门湾大范围表层沉积物样品以及收集到的实测水文资料,分析研究九龙江口-厦门湾表层沉积物的粒度分布特征,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:九龙江口-厦门湾海域沉积类型较多,主要以黏土质粉砂为主,显示出该区域以细颗粒物质沉积为主的沉积特性,同时不同区域沉积物分布特征又略有差异,揭示了九龙江口-厦门湾各海区沉积物颗粒的粗细、水动力条件以及沉积环境的不同.应用GSTA模型对表层沉积物运移趋势分析结果显示,来自九龙江径流的物质一部分在九龙江口受到潮流作用沉积,一部分通过厦门湾口往外海输运,还有少量在涨潮流的作用下进入厦门西海域,该趋势与水动力条件密切相关.

| Abstract: | Grain size parameter is the most important information of sediment which can point out the characteristics of distribution and transportation.Based on analysis data of 230 samples which were collected from the sea area of Jiulongjiang estuary and Xiamen bay in Sep.2008,a study on the grain size properties distribution of seabed surface sediment in the study sea area is conducted.At the same time,through the GSTA(Grain Size Transport Analysis) model,a conveying trend analysis of sediment in this basin has be... |
