| 中文摘要 |
| 通过云南泸沽湖─半封闭深水湖泊湖水和沉积物孔隙水中Ca2+、K+、Na+、HCO3-等基本组分及pH等剖面分布的研究,结果表明,这些基本组分可以自底部沉积物向上覆水体扩散迁移。定量地估算了扩散通量及其对上覆水体的影响程度,说明湖泊沉积物-水界面作用在控制整个水体水化学基本组成中起着重要的作用。 |
| 英文摘要 |
| hrough the study on Ca2+、K+、Na+、HCO3- and pH profiles of water column and porewater of Lake Lugu,Yunnan,a half-close and deep lake,it was found that Ca2+、K+、Na+ and HCO3- in the sediments could diffuse to overlying water and their diffusive flux and their influence extent on overlying water could be quantitatively estimated.At also indicates that the interreactions between sediment and water play a significant role in controlling basic chemical composition of some lakes. |
