摘要

摘要: 连云港近岸海域沉积物的粒度在空间上具有"近岸细、远岸粗"的分布特征.为了探讨粒度的这种空间分布特征,利用端元分析模型和多变量分析方法对108个底质样品粒度特征进行了分析,结果表明,可以把连云港近岸海域沉积物划分为具有一定动力意义的3个粒级组,它们代表不同能量环境下形成的沉积物:潮流沉积、潮流-波浪混合沉积和波浪沉积,这些沉积物对应于前三角洲沉积物、动力改造沉积物以及原地海滩沉积物.

Abstract: Spatial distribution characteristics of grain-size being "fine in nearshore,but coarse in offshore" have been found along the Lianyungang coastal zone.For discussing this distribution,108 samples collected from this region were analyzed with the end-member analysis model and the multivariables analysis method.Results show that the sediment along the Lianyung ang coastal zone can be divided into three grain-size groups with certain dynamic significance,corresponding to the sediment of prodelta,the dynamo-reworking sediment,and the sediment of in situ deposited on sedentary beach,which deposit under different environments,i.e.,depositional environments of tidal current,wave and both of them.
