| 摘 要： | 根据2005年9月黄河口淡-咸水混合过程中表层水体CO2分压(pCO2)和盐度的同步观测资料,对黄河口淡-咸水混合过程中pCO2的变化规律进行了初步探讨.研究结果表明:黄河口pCO2与盐度总体上保持着良好的负相关关系,但在盐度5左右水体pCO2存在亏损现象,这种现象可能是由于河口水体受海水影响,其离子强度突然增加而导致黄河水体中的过饱和碳酸盐发生沉降作用引起的.

| 关 键 词： | 黄河口 CO2分压(pCO2) 总碱度(TAlk) |

| Abstract: | The investigation of distributions of CO2partial pressure(pCO2)and salinity(S) in surface water of Huanghe Estuary was carried out in the Sep.2005.The results showedthat the pCO2and S are the negative correlation in Huanghe Estuary.However,because of the seawater reinforce,the ionic strength abruptly leads to the supersaturated carbonate precipitation in Salinity around 5 which make the pCO2 behave as the loss in the estuary. |

| Keywords: | Huanghe Estuary the carbon dioxide partial pressure(pCO2) total alkalinity(TAlk) |
