水生生物在湖泊生态除磷修复中的影响

研究了不同水深的洞庭湖区芦苇对湖泊中磷的净化效果。结果表明,芦苇在降低湖水磷含量中发挥着重要作用。生长旺季,浅水区和深水区的芦苇根区总磷最高去除率分别为55%和25%以上,表层去除率分别为35%和20%;在枯萎期,根区的总磷去除率也能分别达到30%和20%以上,表层仍能保持15%。结果表明,通过适时收割芦苇,可有效降低湖水中总磷含量。...

The purifying effect of reed on lake phosphorus content with different water depths in the Dongting Lake was studied. The results showed that reed played an important role in reducing lake phosphorus content. During the growth season, the highest total phosphorus（TP） removal rate of shallow and deep water area of reed root zone were 55% and 25%,and the surface removal rate of 35% and 20%, respectively. And in the withering state, the TP removal of root zone could be up to more than 30% and 20%, and maintained 15% in the surface layer. The result shows that TP can be effectively reduced through timely harvesting of reeds in the lake.
