摘　　要：我国城市化的快速发展致使城市机动车道路雨水径流量显著增大,雨水水质明显恶化。采用土柱模拟生物滞留池,考察了其对城市机动车道路雨水径流水质的改善效果,以确定适宜的生物滞留池填料构成。结果表明,在自然装填状态下,生物滞留池种植土壤填料中营养土的含量为5%～10%(相应壤质土的含量为30%～25%,砂的含量为65%)时,对雨水径流中氨氮、TN、TP、COD和SS的去除效果较好。The rapid development of the urbanization experienced in China has led to large volume and poor quality of stormwator runoff on traffic roads, A laboratory hioretention soil column study was conducted to investigate the performance of bioretention pond for improving the quality of stormwater run- off on traffic roads. The aim of the study was to choose a reliable medium in the bloretention pond, In the nature filling state, when the nutrient content in media in bioretention pond was 5% to 10% （the content of loamy sand was 30% to 25%, and that of sand was 65% ）, NH3 - N, TN, rip, COD and SS in traffic road runoff could be removed effectively.
