渤海湾沉积物中氮、磷的空间分布特征研究

对2003-07在渤海湾采集的柱状沉积物中氮、磷的分布进行研究。结果表明,渤海湾柱状沉积物中氮、磷空间分布特征是近岸高,远岸低;近岸P含量达0.410mg/g,远岸含量为0.233mg/g。其中磷主要以无机磷形式存在,无机磷约占总磷的50%以上;渤海湾沉积物中氮含量较高,平均达5.96mg/g。

Spatial distribution of phosphorus and nitrogen in core sediments of Bohai bay

Core sediment samples,collected in July 2003 in the Bohai Bay,were analyzed in this article.The results show that the concentration of nitrogen and phosphorus near seacoast in core sediment of Bohai Bay are higher than those far seacoast.The concentration of near seacoast is (0.410) mg/g,while that of far seacoast is 0.267 mg/g.Inorganic phosphorus (IP) is the main component in the sediment of Bohai Bay,which accounts for about 50% in total phosphorus.At the same time,the concentration of nitrogen in core sediment of Bahai Bay is high,the average content 5.96 mg/g.
