Physical and Chemical Characteristics of Water in Lake Hongfeng during the Disappearance of Seasonal Stratification

  • 摘要: 以云贵高原典型的人工河道型水库红枫湖为研究对象,对近2年来4个代表性湖区季节性热分层消亡期水体的理化特征进行了原位监测. 结果表明:红枫湖水体季节性热分层历经发生、发展和消亡的周期性演化过程,对湖泊水环境的变化起着重要的控制作用. 秋季初期,气温骤降易于引起季节性热分层的突发性消亡,表现为水体垂向混匀. 以2010年为例,分层消失使得上层水温由28.6 ℃降至23.0 ℃,ρ(DO)(溶解氧浓度)由9.6 mg/L降至4.0 mg/L,pH由8.8降至7.9,电导率由0.32 mS/cm升至0.36 mS/cm,局部湖区出现鱼类死亡现象;短时间内的剧烈垂直混合,致使沉积物营养盐扰动释放,上部水体ρ(TP)增加了约0.01 mg/L,ρ(TN)增加了0.1 mg/L. 红枫湖水体垂向混合可对湖泊水环境产生重要影响,其影响的水体深度和环境效应一方面与气温变幅等因素有关,另一方面还受湖泊温跃层位置和底层水体的绝对温度等因素控制,在预测该类突发性水质恶化事件及评估其环境影响时需予以考虑.
