摘　　要：通过对南黄海中部E2站位沉积柱样部分微量元素的特征研究,讨论了近200a来与南黄海中部沉积物相关的主要环境气候演变.铅和金、铂族元素显示人类现代工农业活动对环境的影响在南黄海中部沉积物有明显记录;过渡金属元素和不活泼元素的记录显示小冰期(泛指1550～1850年)的结束,气温的升高对南黄海中部沉积区的氧化-还原条件和黄河流域的风化程度产生了影响;黄河的改道对南黄海中部沉积物陆源碎屑的输入产生影响.By the study of the geochemistry characteristics of trace elements for the sediments of Core E2 from the southern Huanghai Sea,combining with characteristics of environment and climate changes in the last 100～200 a,the results exhibit that Pb and Au,and Pt family showing the influence of modern moving of industry and agriculture on environment have been recorded in the sediments of the southern Huanghai Sea;inactive trace elements and transitive metals elements showing the rising of temperature after the ended modern small ice age had great influenced the condition of oxidation-reduction of sediment zone and the efflorescence of the Huanghe River valley;the changed its course of the Huanghe River had been influenced on the terrestrial input of the sediment for the southern Huanghai Sea.
