摘    要:根据2009年春、夏季大辽河近人海河段的大面站和连续站观测,分析了水体溶解氧(dissolved oxygen,DO)的时空分布规律,并对近人海河段上游低氧区的成因进行了初步探讨.结果表明,水体溶解氧含量在空间分布上呈人海口高、河段上游低,表层高、底层低的趋势;时间分布上呈白天高、夜间低,春季高、夏季低的趋势.夏季溶解...

关 键 词:溶解氧  低氧  大辽河  河口

Abstract:Based on field surveys in the upper estuarine zone of the Daliaohe River in Spring and Summer of 2009,the spatial and temporal distributions of dissolved oxygen were analyzed and the mechanism of hypoxia were preliminarily discussed.The results indicated that DO concentrations were higher in the river mouth and lower in the upper reaches,higher in surface layers and lower in bottom concerning its spatial distribution.For its temporal distribution,DO concentrations were higher in daytime and lower at night,h...
Keywords:dissolved oxygen  hypoxia  the Daliaohe River  estuary
