| 摘 要： | 通过对山东半岛南部海域147个表层沉积物样品和周边入海河流46个表层沉积物样品进行粒度与元素地球化学测试,系统地研究了主要地球化学元素含量及分布特征,探讨了其影响因素。结果表明:研究区表层沉积物常量元素SiO2、CaO、K2O含量低于我国近海海域平均值,Al2O3、MgO、TFe2O3含量高于我国近海海域平均值,微量元素中重金属含量均高于我国近海海域平均值。表层沉积物粒度、周边入海河流和人类活动是影响元素地球化学分布的主要原因。

| Abstract: | 147 surface sediment samples and 46 river samples were collected from the offshore area of the South Shandong Peninsula and surrounding rivers for study of the distribution pattern of major elements and its controlling factors. The results show that the main elements of SiO2, CaO and K2O are lower than the average of these elements in other coastal areas, whereas Al2O3, MgO, TFe2O3 and heavy metal elements are higher. Grain size of surface sediments, input of surrounding rivers and human activities are the main reasons for the element distribution pattern. |
