摘　　要：对盐城市近岸表层沉积物中元素地球化学特征进行了采样分析,结果表明,表层沉积物中元素不仅与河流等陆源物质来源有关,而且与古潮滩沉积再搬运、再沉积以及人类围垦及排放污染活动有关。同时,多数元素在近岸河流入海口处(射阳港)的含量表现出相对富集的特征,港口和近岸河流排污对此影响较大。The geochemical characteristics of the macro and micro-elements in the surface sediments of the typical positions of Yancheng nearshore were analyzed. Results showed that the nearshore sediment source in Yancheng was not only relevant with the sediment source of river transportation, but also with the re-transport and re-deposition of the paleo-tidal flat sediments. The nearshore materials of Yancheng came not only from the earth crust but also from human activities. Due to the input of wastewater, meanwhile, the contents of most elements were close to their highest values near the outlets of rivers.
