| 摘 要： | 通过建立小型围隔区,研究了沉水植物对富营养化水体中氮、磷等污染物的净化效果,以及对底泥中磷含量的影响.结果表明:(1)在放养沉水植物的围隔水体中各种营养盐浓度明显低于对照围隔;(2)沉水植物对磷的吸收能够有效地保持底泥中磷的含量,而在对照围隔中的底泥中磷元素含量却不断增加;(3)经50天后,水体中TN、NH4 -N、TP、PO43--P和CODMn平均去除率分别为36.3%、70.5%、54.6%、65.4%和43.1%. |

| Abstract: | The effects of submerged plants on the purification efficiency of nutrient contaminations and phosphorus concentration in sediment were studied by using constructed pony enclosures. The results showed that: (1) The nutrient concentrations in the enclosures that planted submerged plants were lower than control enclosure obviously; (2) The submerged plants can use phosphorous in sediment effectively by absorbing while the concentration of phosphorous in sediment of control enclosure was increasing during the study; (3) After 50 days , the average removal ratios for total nitrogen, ammonia nitrogen , total phosphorous, phosphate and COD_ Mn in planted enclosures were 36.3%, 70.5%, 54.6%, 65.4%and 43.1%, respectively. |
