黄、渤海区沉积物中磷的分布

对1998年9月和1999年5月的渤海航次、1998年5月南黄海航次、1999年8月北黄海航次所采集的表层和柱状沉积物样品中总磷和无机磷的含量及分布进行了系统分析和讨论，结果表明：黄、渤海沉积物无机磷占总磷的70%-80%，以无机磷为主，有机磷次之。受海流及陆地河流注入的影响，渤海海区沉积物中无机磷的总磷含量的最大值出现在黄河口附近，而黄海海区沉积物中无机磷和总磷含量的最大值出现在南黄海的西南部；整个黄、渤海海区无机磷和总磷含量的最小值则出现在山东半岛的成山头附近与朝鲜半岛西海岸之间的海区。由于海流作用及生物扰动，所采集的柱状样品中磷的含量产生了一定的波动，但总体趋势还是表层沉积物中磷的含量略高，向下销有减小。

Distribution of phosphorus in sediment of the Bohai and Yellow Sea

Surface and core sediment samples were taken in the Bohai Sea in September 1998 and May 1999, in the Yellow Sea in May 1998 and August 1999 to evaluate the distribution and content of phosphorus in sediment samples in the Bohai Sea and the Yellow Sea. The results demonstrate that the inorganic phosphorus is the main composition in total phosphorus, the phosphate contents in the surface sediments were slightly higher than in the deeper depth, the phosphorus contents reached the maximum near the Huanghe Estuary and the southwest of the Yellow Sea, and the minimum contents were found in the sea area between the Chengshan Cap and the western shore of the Korea peninsula.
