摘要

摘要: 基于连云港近岸海域夏冬季大面积多站表层沉积物样品的粒度分析结果,采用Gisedtrend粒径趋势分析方法,研究了沉积物的运移趋势,探讨了粒径趋势分析的影响因素,结果表明,连云港近岸海域沉积物运移趋势较显著,在海州湾海域沉积物运移趋势为西南向,表现为湾顶淤积;在港口南部海域沉积物运移趋势显示为汇聚区。特征距离、采样网格、周围环境和粒度组分影响粒径趋势的分析结果;综合考虑岸线、岛屿、人工边界等自然环境以及多源粒度组分能够提高粒径趋势分析结果的合理性。

Abstract: On the basis of the grain size analysis of surface sediment samples collected from Lianyungang coastal waters in winter and summer respectively,sediment transport trends are studied using the method of Gisedtrend,and influence factors are also discussed. The results show that the sediment transport trends in Lianyungang coastal waters are obvious. The sediment transport trends in the Haizhou Bay are southwest ward,which is consistent with the silting on the top of the bay. The sediment transport trends south of the port area are convergent. A characteristic distance,a sampling grid,a surrounding environment,and grain size fractions have a direct effect on a grain size trend analysis. Taking into account the influence of coastline,island,artificial boundary as well as the grain size fractions can enhance the reasonability of the grain size trend analysis.
