摘要
为了解沉积物-水界面作为水体HCO^-3的源还是汇,选择云南洱海和泸沽湖两个湖泊,通过界面精细剖面和平衡计算,揭示了HCO^-在界面的地球化学行为。结果表明,界面作为HCO^-3的源,并非汇,通过沉积物和水相作用可以影响上覆水体的酸碱平衡关系。
In order to understand sediment-water interaction as source or sink of HCO_3 ̄-,through studying detail profiles of HCO_3 ̄-and balance budget,the paper chose lake Lugu and Erhai are chosed to describe HCO_3 ̄- geochemical behavior at the sediment-water interface.The results showed that the interface is the source of HCO_3 ̄- of the overlying water mass, not the sink,and that it Can affact acid-alkaline balance of the overlying water mass by means of diffusion.
