| 摘 要： | 利用自行研制的光生物反应器,以水库中典型的铜绿微囊藻(Microcystis aeruginosa)和斜生栅藻(Scenedesmus obliquus)为研究对象,研究了两种藻类在光照强度周期性波动条件下的抑制特性.结果表明,相对恒定时平均光照强度6100 lx而言,在光照强度周期性波动条件下,在培养至24天时,铜绿微囊藻生物量降低14%、颜色稍黄,斜生栅藻生物量降低24%、藻体严重泛黄;铜绿微囊藻的叶绿素a和类胡萝卜素含量分别降低12.7%和55.5%,斜生栅藻的叶绿素a和类胡萝卜素含量分别降低78%和74%;模拟内波的周期性波动光强下,两种藻的光合作用参数Fv/Fm、YⅡ和ETR下降,热耗散量NPQ增高,且光合作用受到抑制,生长代谢能力减弱,这为内波控藻提供了理论依据.
