摘 要: | The adsorption/desorption of phosphorus across the sediment -water interface is the main mechanism that controls the buffering capacity of DRP in coastal and estuarine water. Determination by three processes revealed that: 1) DRP flux from early diagenesis in surface sediment is F = 31.9ug/(m2.d ), which is only 1/1600 of the ammonia released; 2) at normal temperature and in the long term, the TDP released by adsorption /desorption across the sediment-water interface is a function of the major environmental factors; and 3) based on the determined SODR and assumed average water depth H(m) and residence time tR(d), the maximum flux of DRP can be estimated.
