The consumption of oxygen in ice covered lakes is analyzed and related to biological oxygen demand and sediment oxygen demand. An approach for computing dissolved oxygen concentration is suggested assuming horizontally mixed waters and negligible vertical dispersion. It is found that the depletion of dissolved oxygen is mainly due to the transfer of oxygen at the water/sediment interface. The morphology of a lake is very important for how fast the dissolved oxygen concentration is reduced during winter.

冰覆盖湖泊中溶解氧消耗量对湖泊形态的依赖性

对冰层湖泊中的氧气消耗进行了分析，并与生物需氧量和沉积物需氧量相关。建议采用一种计算溶解氧浓度的方法，假设水体水平混合且垂直分布可忽略不计。发现溶解氧的耗竭主要是由于水/沉积物界面处的氧气转移。湖泊的形态对于冬季溶解氧浓度降低的速度非常重要。
