中文摘要:

采用微宇宙培养法,模拟研究了不同曝气方式(底泥曝气、水曝气)对富营养化景观水体中浮游藻类群落结构的影响及影响因子。结果表明:水曝气使得水体溶解氧(DO)急剧增加,从而促进了水体藻类的生长,优势藻种由绿藻门急剧迁移到黄藻门的黄丝藻属;由于泥曝气对底泥中P释放的抑制作用,及浊度增加导致占藻类主要成分的蓝藻门藻类的不断消亡,而明显的抑制了藻类的生长,优势藻种也由绿藻门迁移到硅藻门。因此,在景观水处理技术中加入人工曝气时,应采用泥曝气的方式。

英文摘要:

Tank microcosm was used to simulate effects of different aeration ways(aerating to sediment,aerating to water) on alga communities in eutrophic landscape water body,and their affecting factors were studied.The results showed that aerating to water could greatly enhance the alga growth and make DO increase in the eutrophication process of landscape water body,and the dominant alga in water body was rapidly changed from Chlorophyta to Xanthophyta.As aerating to sediment restrained the release of P from sedime...
