摘要
菊花岛周围海域38个站表层沉积物的铁、锰、铝、钛、磷、有机质、氮、铜、锌、铅、镉、镍和汞等化学要素含量的Q型因子分析计算表明,本区可划分为三个化学元素沉积区:1.海流悬浮沉积区;2.近岸波浪作用区;3.波浪海流作用区。柱状沉积物中铁等化学元素的迁移、富集受氧化——还原界面的控制。
The results of chemical analysis for the surface samples and the core samples from sea bed around Juhua Island have shown that Fe, Mn, Al, Ti, P, organi matter, N, Cu, Zn, Pb, Cd, Ni and Hg accumulate in clay sediment. Q-factor analysis reveals that the study area can be divided into three characteristic zones: 1. suspended deposit zone where sea currents dominate, 2. nearshore wave action zone, and 3. wave-current interaction zone. The concentrations of Fe, Mn, P, organic matter, N, Cu, Zn, Pb and Ni in the first zone are the highest, those in the second zone are lower, and those in the third zone are the lowest.
