摘要
分析了最近在南黄海获取的283个站位的表面沉积物样品,获取了粒度、元素含量等多项指标。对粒级含量、元素含量做了相关分析,得出如下结论:并非所有元素分布都受沉积物粒度控制;具有粒度效应的元素不受所有粒级控制;元素含量与各粒级的含量呈"\"、"/"、"N"、反"N"4种关系。这些发现对剔除元素分布的粒度效应,为利用元素分布来识别沉积物物源提供了基础性认识。
The surface sediment samples collected from 283 stations in the southern Yellow Sea were analysed, and the sediment granularity and chemical composition data were obtained. It is shown from the correlation analysis between sediment granularity and chemical composition that not all the chemical composition distributions are controlled by the sediment granularity, and the scatter diagrams of correlation between chemical composition and granularity show 4 patterns, `\′shaped, `/′shaped, `N′shaped and inverse `N′shaped patterns. The above study results provide scientific basis for eliminating the granllarity effect of chemical composition distribution and identifying the sediment source by using the chemical composition distribution.
