研究了东、黄海海域典型站位柱状沉积物中总磷(TP)、无机磷(IP)及有机磷(OP)的含量及其分布特征.东海、黄海海域3种形态磷的浓度范围分别如下:东海:TP 13.73～19.85 μmol·g~(-1),IP 11.39～16.03 μmol·g~(-1)和OP 2.11～3.81 μmol·g~(-1);黄海:TP 14.44～18.33 μmol·g~(-1);IP 11.79～15.88 μmol·g~(-1)和OP 2.45～2.65 μmol·g~(-1).两海区沉积物中IP/TP和OP/TP变化范围分别为79%～88%和12%～21%.IP是研究海域沉积物中磷的主要存在形式,陆源输入为影响沉积物磷浓度的主要因素.地处长江口附近的E4站和东海中部海区的E6站分别为所有调查站位中各形态磷浓度的最高和最低者.不同海区柱状沉积物中各形态磷浓度的垂直分布特点不同.其分布特征在一定程度上反映了相应历史时段该站位营养盐输入水平、自然条件和人类活动的重大变化.
研究瞭東、黃海海域典型站位柱狀沉積物中總燐(TP)、無機燐(IP)及有機燐(OP)的含量及其分佈特徵.東海、黃海海域3種形態燐的濃度範圍分彆如下:東海:TP 13.73～19.85 μmol·g~(-1),IP 11.39～16.03 μmol·g~(-1)和OP 2.11～3.81 μmol·g~(-1);黃海:TP 14.44～18.33 μmol·g~(-1);IP 11.79～15.88 μmol·g~(-1)和OP 2.45～2.65 μmol·g~(-1).兩海區沉積物中IP/TP和OP/TP變化範圍分彆為79%～88%和12%～21%.IP是研究海域沉積物中燐的主要存在形式,陸源輸入為影響沉積物燐濃度的主要因素.地處長江口附近的E4站和東海中部海區的E6站分彆為所有調查站位中各形態燐濃度的最高和最低者.不同海區柱狀沉積物中各形態燐濃度的垂直分佈特點不同.其分佈特徵在一定程度上反映瞭相應歷史時段該站位營養鹽輸入水平、自然條件和人類活動的重大變化.

The concentrations and distribution of the TP, IP and OP in core sediment of the Yellow and East China Seas were examined. The concentrations of phosphorus in sediments of the Yellow Sea were 14.44～18.33 μmol·g~(-1) for TP, 11.79～15.88 μmol·g~(-1) for IP and 2.45～2.65 μmol·g~(-1) for OP. The phosphorus levels in sediments of the East China sediments were 13.73～19.85 μmol·g~(-1) for TP, 11.39～16.03 μmol·g~(-1) for IP and 2.11～3.81 μmol·g~(-1) for OP respectively. IP and OP in the investigated stations of the Yellow and East China Seas represented 79%～88% and 12%～21% of TP, respectively. IP was the main form of phosphorus in core sediment of the investigated regions, of which terrigenous input was the major source. The concentrations of phosphorus at Stations E4 and E6 were the highest and lowest among all stations investigated, respectively. The concentrations of TP, IP, OP varied with depth, which increased gradually with depth in the upper layer of the core sediments in regions mainly affected by the riverine input. While the concentrations of phosphorus decreased gradually with depth in the upper layer in areas off the shore. The concentration and distribution features of phosphorus in core sediment were related to anthropogenic activities and environmental condition changes.
