摘　　要：通过室内模拟实验,研究曝气和种植漂筏薹草(Carex pseudocuraica)对富磷水体中磷去除的影响,并分析了水体中总磷含量与水体中其它几种化学组分的关系。研究结果表明,在整个实验过程中,曝气+植物处理下,水体中总磷的去除率稳步提高,而在其它3种处理下,总磷的去除率都波动变化。在曝气+植物处理、曝气+无植物处理、自然复氧+植物处理和自然复氧+无植物处理下,水体中总磷的平均去除率分别为98.15%、97.15%、96.00%和95.88%,曝气和植物共同作用对水体中总磷的去除效果优于单一曝气或植物下的去除效果。在4种处理下,建立了以水中Fe^(2+)、Fe^(3+)和总有机碳含量为自变量,以水体中总磷含量为因变量的线性多元回归模型。The combined effects of artificial aeration and planting of Carex pseudocuraica on total phosphorus removal in phosphorus-rich water were studied by laboratory simulation experiment. The relationships be- tween total phosphorus content and other chemical components in water were also analyzed. The results showed that the removal efficiencies of total phosphorus under aeration＋plant treatment had been climbing steadily during the whole experiment, while the removal efficiencies of total phosphorus were fluctuating un- der the other three treatments. The removal efficiencies of total phosphorus of overlying water were 98.15%, 97.15%, 96.00% and 95.88% under the aeration＋plant, aeration＋no-plant, ambient＋plant and ambient＋ no-plant treatment respectively, indicating that the combined effects of aeration and plant on removal efficien- cies of total phosphorus took an advantage over either single aeration or plant. We also established a multiple linear regression model, with total phosphorus contents as the dependent variable, while Fe2＋, Fe3＋and total or- ganic carbon contents as the independent variables.
