摘　　要：通过现场试验对水体水质指标、植物的适应性与抗逆性以及植物体内的TN、TP指标进行了检测,筛选出适合西安市景观水体生物浮床的最优植物——美人蕉、适合人工湿地的最佳挺水植物——水菖蒲。对各项指标的综合分析结果表明,以美人蕉和鸢尾为主、其他植物为辅,并与生物膜相结合而构建的人工生物浮床具有较合理的生物群落结构,其对景观水体的治理效果高于人工湿地,这证明了人工生物浮床和生物接触氧化技术相结合的可行性和优越性。The water quality index, plant adaptability and resistance, TN and TP indexes in plants were detected through field test. Canna indica that is well adapted to bio-floating rafts in Xi ＇ an land- scape waters and Acorus calamus that is well adapted to constructed wetlands were selected. The compre- hensive analysis results of the indexes show that the artificial bio-floating rafts that composed mainly of Canna indiea and Iris tectorum accompanied by other plants, and combined with biofilm have quite rea- sonable biological community structure. The treatment effect of landscape waters by the artificial bio-floating rafts is higher than that by constructed wetlands. This shows the feasibility and superiority of combining artificial bio-floating rafts with biological contact oxidation technology.
