本文研究结果认为,东海陆架近岸区底部上覆水中的SO_4~(2-)浓度,在夏季丰水期普遍低于表层间隙水中的浓度,并由此产生指向上覆水的SO_4~(2-)负通量;秋季的情况正好相反。其原因与季节性的淡水稀释、硫的化学成岩以及生物扰动等因素有关。
The results show that the concentration of SO 4 2- in the overlying water at the bottom of the nearshore area of the East China Sea shelf is generally lower than that in the surface water during the summer wet season and the concentration of SO 4 4- ) The negative flux; the fall is the opposite. The reason is related to seasonal dilution of freshwater, chemical diagenesis of sulfur and bioturbation.
