| 摘 要： | 在绿色屋面的推广过程中,发现部分绿色屋面的雨水径流水质变差,成为潜在的新污染源.为了验证该现象,通过对三个绿色屋面及一个裸露屋面九场的雨水进行采样检测.对比绿色屋面与裸露屋面水质数据显示：pH值上升29％,说明绿色屋面可减轻酸雨对环境的影响；绿色屋面的电导率、硝酸盐、氨氮、总磷、化学需氧量、悬浮固体物指标分别上升606％、616％、117％、1 114％、537％、944％,绿色屋面存在水质变差的情况.研究显示绿色屋面径流水质与其使用期长短、维护情况、生长基质使用以及施肥行为有关.

| Abstract: | The rainwater runoff of some green roof was found to be of low water quality, which even became a new pollution source. The rainwater from three green roofs and a bare roof was collected and sampled to determine the effect of green roofs. The pH value of the rainwater from the green roofs was improved by 29%, illustrating that the green roof can reduce the impact of acid rain on the environment. Indicators of the rainwater from the greenroof such as conductivity, nitrate, NH3 - N, total phosphate （TP）, chemical oxygen demand （COD） and suspension solids （SS） increased by 606% ,616%, 117%, 1114%, 537%, 944%, showing that the rainwater runoff water quality de- creases. The results indicate that the runoff quality is related to the lifespan and maintenance of the green roof, the condition of growth substrate and fertilizer. |
