选取白洋淀优势沉水植物轮藻(Chara sp.)作为建群种,研究其修复白洋淀富营养化水体的效果。室内模拟实验表明,轮藻群落对水体叶绿素a和营养盐的抑制效果明显,实验结束时,水体叶绿素a、氨氮、总氮和总磷含量分别为实验开始时的24.85%、39.2%、30.7%和23.2%。野外不同轮藻覆盖度围隔实验结果表明,围隔中轮藻覆盖度为80%时,水体中叶绿素a、氨氮、磷酸盐和总磷含量减少最明显。实验结果表明,轮藻作为建种群修复白洋淀富营养化水体是可行的。

Charophyte as a dominant submerged plant in the Baiyangdian Lake was selected to test the ability of eutrophic water restoration. The indoor simulation experiment showed Chara sp. community had reduced chlorophyll and nutrients contents. Chlorophyll-a, ammonia nitrogen, total nitrogen and total phosphorus re- duced to 24.85%, 39.2%, 30.7% and 23.2% of the initial concentration respectively. The field trial experiment of the charophyte coverage regulation showed that the controlling effect on the concentrations of chloro- phyll-a, ammonia nitrogen, phosphate, and total phosphorus in water was t...
