| 摘 要： | 通过对长江口南槽水域营养盐时空变化的研究表明,南槽水域营养盐主要以硝酸盐为主,分布比较稳定;垂向分布特征明显,其中NH3N和NO-3N由表层到底层呈下降趋势;无机氮盐在小潮时含量较高,并且受涨落潮影响较小,总磷大潮时含量较高,受涨落潮影响较大;一个潮周期内营养盐的波动范围较小;营养盐的含量与水样中含沙量以及盐度的相关系数较低。

| Abstract: | The temporal and spatial distribution of nutrients in the South Passage of the Changjiang estuary is studied in this paper. Results showed that NO-_3-N is the mainly important nutrients in this district. The characteristic of upright distribution is obvious and the concentrations of NH_3-N, NO-_3-N go down from surface to bottom. The concentration of nitrogen is higher in neap tidal and has little effect by ebb and flood tidal, while the concentration of phosphate is higher in spring tidal and has large effect by ebb and flood tidal. The concentration of nutrients has little relativity with suspended sediment concentration and salt concentration. |
