摘要
根据2016年东海区断面调查资料,采用流动分析法对海水中磷酸盐(PO_4-P)、亚硝酸盐(NO_2-N)、硝酸盐(NO_3-N)、氨盐(NH_4-N)、硅酸盐(SiO_3-Si)5项营养盐进行了分布格局研究。结果表明,磷酸盐含量高值主要出现在东海北部及长江口和舟山群岛外侧海域,而黑潮区和台湾暖流海域则存在大片低值区;除黑潮区和台湾暖流海域表层无机氮(DIN)含量较低外,东海长江口邻近海域和江浙沿岸海域表层DIN含量均较高;硅酸盐含量分布除东海北部和江浙近海海域硅酸盐含量低于0.32 mg/L外,其余海区表层硅酸盐含量均低于该值。
Based on the data obtained from the survey of the east sea area in 2016,the distribution pattern of phosphate( PO4-P),nitrite( NO2-N),nitrate( NO3-N),ammonia salts( NH4-N) and silicate( SiO3-Si) in seawater were studied by flow analysis. The results showed as followed: the high phosphate content mainly appeared in the north East China Sea and the outer waters of the Yangtze river estuary and the Zhoushan islands,while the black tide area and the Taiwan warm waters had large area of low value,in addition to the lower surface inorganic nitrogen( DIN) of the black tide area and the Taiwan warm current,the adjacent waters of the Changjiang estuary of the East China Sea and the surface DIN of the coastal waters of the Jiangsu and Zhejiang provinces were higher; the content of silicate distribution was lower than 0.32 mg/L in the northern and coastal waters of the East China Sea,and the surface silicate content of the remaining sea areas was lower than that.
