本文研究了东海海水中无机颗粒物Fe,Al和Co的分布特征与水系及沉积物分布的关系。指出,上述元素在东海西北部含量最高,分布异常的主要原因是由于黄海沿岸流携带着大量悬浮物质引起的。又指出,在32°N,125°E附近,由于受几股流系的阻挡,流速减慢,较多的悬浮体被聚集在这里。据推测,无机颗粒物Fe,Al和Co的分布异常区的逐年平均中心位置和范围,可能也是海底软泥分布的中心位置和范围。 In this paper, the relationship between the distribution characteristics of Fe, Al and Co in the East China Sea sea water and the distribution of sediments and sediments was studied. It is pointed out that the above elements are the most abundant and distributed in the northwestern East China Sea due to the large amount of suspended matter carried by the Yellow Sea coast. Also pointed out that in the 32 ° N, 125 ° E in the vicinity, due to the blocking of several flow lines, the flow rate slowed down, more suspension is gathered here. It is speculated that the annual average center position and the range of the anomalous distribution of the inorganic particles Fe, Al and Co may also be the central position and the range of the sea mud distribution.
