摘要：

为了研究屋顶绿化对屋面径流水量水质的影响,对成都市2个不同类型绿色屋顶(绿A及绿B屋顶)2010年3月至2011年6月的屋面径流水量水质进行监测,以普通混凝土屋顶为对照屋顶.研究结果表明,两绿色屋顶总截流率近65%,且截流率随雨强的增大而减小.两绿色屋顶都能够提高雨水pH值近1.5.绿A屋顶径流TN、TP和CODcr质量浓度均值依次为2.07、0.08、23.8 mg/L,总负荷依次较对照屋顶降低了84.2%、19.0%、61.4%.绿B屋顶径流TN、TP和CODcr质量浓度均值依次为12.30、0.135、34.5 mg/L,TN和CODcr总负荷分别较对照屋顶降低了47.2%和48.1%,TP总负荷较对照屋顶升高了11.4%.研究表明：绿色屋顶的截流效果显著|与对照屋顶相比,绿A屋顶对屋面径流污染有改善作用,绿B屋顶加剧了屋面径流P污染.
Abstract:

To quantify the influence of greenroofs on runoff mitigation and runoff quality, a field experiment was conducted based on two greenroofs (named green A and green B) in Chengdu, China from March 2010 to June 2011, and the results were compared to a non-vegetated concrete control roof. Both two greenroofs had nearly 65% retention capacity on the whole monitoring period, and the retention capacity was reduced by the increase of rain intensity. Both two greenroofs increased rain pH value nearly 1.5. Runoff’s mean mass concentrations of total nitrogen(TN), total phosphorus (TP) and chemical oxygen demand (CODcr) from green A roof were 2.07, 0.08 and 23.8 mg/L. The total loads reduced 84.2%, 19.0%, 61.4% compared to concrete control roof. Runoff’s mean mass concentrations of TN, TP and CODcr from green B roof were 12.30, 0.135 and 34.5 mg/L. Compared to concrete control roof, the total loads of TN and CODcr reduced 47.2% and 48.1%, and the total load of TP increased 11.4%. Compared to concrete control roof, green A roof improved the runoff quality while green B roof aggravated the pollution of P.
