摘要
对黄海陆架区的 7条测线的表层沉积物样品进行了总磷 (TP)的分析测定 ,阐述了调查海区TP的平面分布特征 ,通过分析水动力条件、粒度及磷的自生作用等因素 ,探讨了TP聚集区和分散区的成因 ,发现沉积物的粒径与TP含量的相关性较差 ,与其他区域P的丰度进行比较后 ,认为黄海表层沉积物中P为非陆源性的 ,并处于“弱贫化”状态。
Total phosphorus contents in surface sediment samples in Yellow Sea were analyzed. The characteristic of TP planar distribution was described in the survey area. There existed several TP accumulation areas and dispersion areas. It was resulted from hydrodynamic condition, grain size, authigenesis of P and ect. factors. The relativity between TP contents and grain size of sediments was found rather low. By comparison P abundance in survey area with that in other areas, it was believed that P in surface sediment of Yellow Sea was non-terrigenous and was in the condition of weak depletion.
