| 摘 要： | 利用2种植物带(芦苇、香蒲与芦苇)对受非点源污染河水进行植物带处理污染物的降解效果模拟试验研究。结果表明，植物带处理污染物的降解效果明显优于无植物带，且以混合植物带效果最好。香蒲与芦苇植物带对COD、TN、TP和NH3-N去除率的周平均值分别为31.62%、37.84%、30.65%和34.31%。植物带能够截留地表径流中的颗粒物，提高水域中的溶解氧含量，对防止水土流失与改善流域水质均有显著作用。

| Abstract: | The non-point source polluted river water is treated by the degradation of riparian vegetation buffer belt, i.e. reed vegetation belt, reed and bulrush integration vegetation belt. The results indicate that the degradation effect with vegetation belt is better than that without vegetation belt, and the degradation effect of reed and bulrush integration vegetation belt is the best. The weekly removal rates of bulrush and reed integration vegetation belt to COD, TN, TP and NH3-N are 31.62%, 37.84%, 30.65% and 34.31%. The vegetation belt can withhold the particles in surface runoff and enhance the dissolved oxygen (DO) content in river, which is important to prevent water and soil erosion and to improve the water quality. |
