Abstract:

气泡释放是天然水体中水-气交换的重要途径之一.采用改进的倒置漏斗型气泡通量监测装置于2012年38月期间对三峡支流澎溪河高阳平湖库湾水域进行气泡释放通量的监测研究.研究期间,研究水域CH4气泡释放通量变化范围为0.01~23288.64μmol/(m2·d);CO2气泡释放通量变化范围为0~799.89μmol/(m2·d).不同常规采样点CH4、CO2气泡释放通量均呈现出高度的时空异质性特征.但CH4气泡释放通量显著高于CO2气泡释放通量,且二者释放过程具有同步性.同国外已有水库监测结果相比,澎溪河回水区高阳平湖库湾水域CH4、CO2气泡释放通量位于中等水平.CH4气泡释放通量约为同期CH4扩散通量的0~1893.90%,超量释放下CH4气泡释放通量可达同水域CH4扩散通量的6270.5%±390.0%.CO2气泡释放通量仅占同期扩散通量绝对值的0~21.74‰,超量释放下,CO2气泡释放通量亦仅为同期扩散通量绝对值的40.33‰±0.93‰.CH4气泡释放通量在支流库湾水域对总通量的贡献不可忽视.
