| 摘 要： | 于１９８９年５月在黄河口海区采集４个沉积物柱状样,以原子吸收法测定其碳酸盐组分中Ｃａ,Ｍｇ,Ｆｅ,Ｎａ,Ｍｎ元素的含量。结果表明,含量分布基本遵循“元素粒度控制律”,即沉积物粒度细时,元素含量超于富集。结果还证明,受黄河水影响越大,沉积物碳酸盐Ｍｎ／Ｆｅ比值越高,可以以此判断沉积物受黄河水影响的程度;ＣａＣＯ３含量亦存在类似现象。相关分析表明,碳酸盐组分中Ｍｎ含量与ＣａＣＯ３含量相关较好,而Ｆｅ与

| Abstract: | The contents of Ca, Mg, Fe, Na and Mn in the carbonate fraction of 4 sediment core samples from the Huanghe River Estuary were measured with FAA method in Mal, 1989. The result shows that since 1855 the Huanghe River channel moved northward to flow into Bohai Sea, the CaCO3 content in the sediment is obviously higher in the area influenced by the river water. The highest content occured in the cores 4-3 and 9-2 in the sections affected heavily by the river water, with the maximum value of 14%, and the minimum value of 4% found to be in the depth of 30 cm, core 3-3, sedimentated during the period of the Huanghe River flowed into Qingshuigou, with little influence on the sample. The result also shows that the element contents correspond to "the rule of the granularity controlling", i.e., the finer the sediment particle size, the higher the element content, and that the heavier the sediment is affected by the Huanghe River material, thte greater the Mn/Fe ratio is, which can be reversely used to determine the effects level of the sediment by the Huanghe River. The CaCO3 content has a similar phenomenon to the Mn/Fe ratio.The correlation analysis gives that the Mn content of the carbonates has a good relationship with the CaCO3 content, but Fe does not. |
