摘要
根据 1998年 4月到 2 0 0 0年 4月对湛江港海水的五期调查结果 ,讨论了海水中氮、磷含量及其营养盐分布特征。结果表明 ,湛江港海水中营养盐含量较高 ,超标严重 ;营养盐与盐度呈现出负相关的规律性 ,无机氮表层高于底层 ,无机磷底层高于表层 ;
From five surveying results in seawater of Zhanjiang Port obtained from April 1998 to April 2000,the concentrations of NO - 2-N,NO - 3-N,NO + 4-N,PO 3- 4-P and distribution characteristics of the nutrient in the seawater are discussed.The results show that the nutrient concentrations in this area were rather high,and most of them exceed the seawater standard remarkably.The nutrient concentrations displays the negative correlation with salinity,DIN was higher in the surface than the bottom and DIP was higher in the bottom than the surface.Different kinds of nutrient displays different annual variation.
