摘要
利用 1998年 5月南黄海大面调查所得到的数据和相关的历史资料 ,对南黄海海水中P的现状及其分布变化规律进行了分析 :南黄海海水中P的含量底层略高于表层 ,且主要存在形式是DOP ;底层水中颗粒态磷和溶解态磷的形态间转化与表层不同 ,可能是通过DOP为煤介进行的 ;在南黄海海水中 ,溶解态磷酸盐的分布主要是受生物活动的影响 ,可以作为赤潮发生的一个预测因子 ;南黄海的大部分区域N、P供应充分 ,属于中等营养海区。
The studies on the distribution and variation of the specification of phosphorus in the southern part of the Yellow Sea were made. The biogeochemistry of phosphorus in the Yellow Sea was discussed. The phosphorus is slightly higher in the bottom than in the surface in the southern part of the Yellow Sea and dissolved organic phosphorus was the main form comparison with the historical data. The transfer forms between various forms of particulate and dissolved phosphorus were different in the bottom and aurface, probably due to the contribute of dissolved organic phosphorus. The distributions of dissolved inorganic phosphorus and dissolved organic phosphorus were mainly affected by the biological processes and could be as a prediction factor for the red tide. The supply on N and P in most of the areas in the southern part of the Yellow Sea is sufficient, without apparent limitation of N or P.
