摘要
根据1991年在大亚湾西南部水域进行全年性环境调查的结果,综合讨论该水域磷、硅酸盐含量分布特征.调查结果表明,磷、硅酸盐春季较低,冬季最高,跟叶绿素a密切相关,其中磷、硅表、底层含量差值与水温、溶解氧表、底层差值呈负相关.该水域P:∑N:Si比值为1:5:58.
Based on the investigation data in the waters of southwest Daya Bay from December 1990 through December 1991,the distribution of phosphate and silicate is dealt with in this pater. It is indicated that the annual average value of phosphate and silicate were 0. 36μmol/L and 20.1μmol/L and the concentration values were higher in winter and lower in spring. The difference between the surface and bottom value of phosphate and silicate was negatively correlated with the difference between that of temperature and DO. The ratio between P, ∑N and Si was P:∑N:Si=1:5:58 in the waters.
