| 摘 要： | 对渤海77个表层沉积物的8种化学成分进行了分析,指出其含量与黄海和东海接近,属正常陆架海范畴,化学成分含量受沉积物粒度控制。根据R型因子分析,判断出控制化学成分分布的三个主要因素,并据此将渤海划分成三个地球化学区。

| Abstract: | Eight chemical compositions were analysed for the 77 surface samples from the Bo-hai Sea. The results reveal that their contents, which are all controlled by grain size of the sediments, are not only close to those in the Huanghai Sea and the East China Sea, but also within the range commonly occurring in a normal continental shelf. Based on the R- model factor analysis, the distributions of these compositions are mainly governed by three factors -. the modern hydrodynamic conditions and mechanical differentiation, the strong influence of the material delivered by the Huanghe River and the physical and chemical conditions. On the basis of the results obtained, the Bohai Sea can be divided into three geochemical regions. |
