摘要
以南宁市某绿色屋顶海绵设施作为研究对象,运用KOSIM水文模型模拟计算了其对雨水径流的控制效果。分析了各个相关参数对绿色屋顶控制效能的灵敏程度,结果表明有效调蓄容积对绿色屋顶效能的影响程度最大。此外,还研究了绿色屋顶对径流总量控制率和对污染物总量控制率二者之间的函数关系,结果表明二者呈线性相关,为探索海绵设施对污染物的净化效果提供了方法。
The green roof in Nanning city as a kind of sponge facilities was studied.KOSIM hydrological model was used to simulate the control efficiency of runoff by the green roof.The effective storage volume was proved to be the key influential factor after the sensitivity of the green roof runoff control performance to each parameter was analyzed.In addition,the functional relationship between the total runoff control rate and the total pollutant control rate of green roof was also investigated.It was found that the runoff control rate and pollutant control rate were linearly correlated,which could provide a way to explore the purification effect of sponge facilities on pollutants.
