摘　　要：研究了人工湿地系统中植物生长趋势和水体DO的变化,探讨了污染物的去除与湿地植物生长趋势和水体DO的相关性。结果表明:垂直潜流人工湿地系统对石油类污染物的净化效果很好,且两两系统之间对石油类的去除效果没有显著差异(P>0.05)。石油类污染物去除率与DO相关性较强(r=0.986,P<0.05),与植物生长趋势相关性不显著;栽种植物的湿地系统脱氮除磷的能力均高于对照组。The changes of plant growing trend and DO of the water body in constructed wetland systems have been studied. The correlativity of pollutant removing,with wetland plant growing trend and DO of water body are discussed. The results show that the vertical-flow constructed wetland system has pretty good purifying effect on petroleum pollutants. And,every two constructed wetlands has no significant difference in the removing effect on petroleum（P0.05）. The petroleum pollutants removing rate has strong correlativity with DO（r=0.986,P0.05） but does not have obvious correlativity with plant growing trend. The denitrification and dephosphorization capacities of planting plants in wetland system are all higher than that of the control group.
