摘　　要： 采用植生混凝土河道护坡模拟装置,分别在植生混凝土砌块上种植百喜草、紫花苜蓿、白三叶、早熟禾、黑麦草、红三叶、狗牙根等7种植物,考察不同植生混凝土对污染河水的净化效果。结果表明,黑麦草混凝土砌块的净化效果最好,对COD、NH4+-N、TN、TP和浊度的去除率分别为59.4%、84.2%、38.9%、95.1%和71.0%;而空白植生混凝土对污染河水也有一定的净化作用,对COD、NH4+-N、TN、TP和浊度的去除率分别为35.4%、52.5%、23.2%、68.9%和61.2%。 The effect of simulated concrete embankment on water purification was studied in seven kinds of planting concrete blocks with different slope-protecting plants （ Paspalum notatum, Medicago sativa L. , Trifolium repens , Poa pratensis L. , Lolium perenne L. , Trifolium pratense , Cynodon dactylon L. ）. The main object was to investigate the water purification effect of the planting concrete, which was a new type of embankment material. The results showed that the planting concrete blocks with Lolium perenne L. had the best performance, and the removal rates of COD, NH4^＋ - N, TN, TP and turbidity were 59.4% ,84.2% , 38.9% , 95.1% and 71. 0% respectively. Blank planting concrete also had good purlfication effect, and the removal rates of COD, NH4 -N, TN, TP and turbidity were 35.4%, 52.5%, 23.2%, 68.9% and 61.2% respectively.
