中文摘要:

为控制白洋淀的水体富营养化状况,在所选实验水域建立由不同类型的食物链组成的围隔生态系统。从2010年8月份到10月份每周采样一次,共8次,测定水体中的pH、溶解氧(DO)、透明度(SD)、高锰酸盐指数(CODMn)、总氮(TN)、氨氮、总磷(TP)、叶绿素a的浓度,研究围隔生态系统对于水质的影响作用。实验结果表明:实验初期围隔内水质明显好转,富营养化程度降低。在各个实验组中金鱼藻组对于水质的改善作用最为明显,对SD、DO、CODMn、TP、TN、NH 4+-N、叶绿素a等水质指标的改变率分别达到192%、204%、73.8%、21.3%、56.0%、75.0%、28.6%,使水体的富营养化指数减低为初始值的74%。

英文摘要:

The enclosures with different food chains were seted in Baiyangdian lake in order to control eutrophication.From August 2010 to october water samples in Baiyangdian like were collected once a week,eight times together.Through measuring the concentration of pH,DO,SD,CODMn,TN,NH+4-N,TP and chlorophyll-a,the paper researched the effect of enclosure ecological system to water quality.The result shows that the water quality turned better obviously and the level of eutrophication reduced at early time of experime...
