在有光的条件下，浮游藻类和一些光自养生物对沉积物水界面溶解态的营养盐的直接吸收，从而减少了上覆水中可与沉积物可交换的营养盐的含量；

Many phytoplankton and autotroph absorb the DIN of the bottom water that decrease content of DIN in bottom water and change the fluxes of the DIN.

陆架浅海沉积物—海水界面上的溶解态生源物质通量的准确估算是海洋生态系统动力学研究中的关键性问题之一。

One of the key issues in the marine ecosystem dynamics studies is to accurately estimate the dissolved biogenic substance flux across the sediment-seawater interface in the shelf sea.
