通过对2006年夏季对北黄海的现场调查,对该海域磷的形态和分布特征进行了探讨.结果表明: 夏季北黄海海域总磷(TP)浓度的变化范围是0.00～1.63 μmol/L,其中溶解无机磷(DIP)是最主要的存在形式,占TP的44%,溶解有机磷(DOP)略低,颗粒磷(PP)最少,总磷的分布呈现由南向北逐渐增高的趋势.北黄海海域水体中各种形态磷(除DOP外)均是表层低于底层,表底层PP的含量相差不大, 表层以DOP为主要存在形态,而底层则以DIP为主,大部分DIP浓度高的区域恰好是DOP浓度的低值区,一定程度上存在着负相关关系(r=-0.34).这样的分布趋势除了受生物活动的影响外,在底部海域还与黄海冷水团密切相关.

Based on the data collected in summer 2006, the forms and distribution of phosphorus in the North Yellow Sea were discussed. The total phosphorus(TP)in summer ranged from 0.02 to 1.63 μmol/L.The uppermost form was DIP, and PP was the least. The concentration of TP was gradually increasing from south to north. All forms of phosphorus except for DOP were higher in the bottom than in the surface. Content of PP was oppositely even. DOP was the leading form in the surface layer, however, it was DIP in the bottom. DIP and DOP were negative correlation in a certain extent and the correlation factor was -0.34. The distributions of DIP and DOP were mainly affected by the biological processes, but it also related to the Yellow Sea Cold Water Mass in the bottom of the sea.
