富营养化富营养化eutrophication由于氮、磷含量过多而引起的水质污染现象。在人类活动的影响下,生物所需营养物质大量进入湖泊、河流和海湾等缓流水体,引起藻类及其他浮游生物迅速繁殖,水体溶解氧量下降,水质恶化,鱼类及其他生物大量死亡。一般认为水体中含磷20mg/m3和无机氮300mg/m3即为富营养化。水体出现富营养化现象时,由于浮游生物大量繁殖,水面往往呈蓝、红、棕、乳白等色,因占优势浮游生物的颜色不同而水的颜色各异。这种现象在江河湖泊中称为水华,在海洋中则称作赤潮。富营养化可使水的透明度降低,阳光难以穿透水层,而影响水中植物的光合作用,减少氧气的释放,使得水中溶解氧减少,从而造成鱼类等生物大量死亡。防止水体富营养化,首先应控制营养物质进入水体;其次可采取疏浚底泥,清除水草和藻类,引入清水冲稀和采用人工曝气等措施;此外,亦可在保证水体溶解氧的条件下,饲养草食性和杂食性鱼类,以消耗水体中的营养物质,减轻其富营养化程度。
