摘要：

为研究热分层和富营养化对湖库溶解氧变化特征的影响,于2014年1月12月对周村水库水温、溶解氧、叶绿素以及初级生产力的季节变化及垂向分布进行了监测.结果表明:水温和溶解氧的分层期均为4～11月份;分层期叶绿素在20～50μg/L之间,初级生产力为2.16～2.23g O2/（m3·d）,光补偿点在1～3m之间;恒温层在5月中旬进入厌氧状态;由于光补偿点位置较高,5～8月份氧跃层位置为1～6m,高于温跃层上界面;而氧跃层位置偏高造成溶解氧在垂向上的极值一般在表层,且变温层溶解氧浓度梯度较大;9～11月份温跃层的下移使得氧跃层和厌氧区界面同时下移,厌氧区界面与温跃层上界面的位置变化始终同步,而氧跃层受水体耗氧作用的影响在热分层结构相对稳定时会再次上移.热分层和水体富营养化均对溶解氧的浓度和分布有重要的影响.
