    摘要:

    为使绿色屋顶技术在城市雨洪管理中有效发挥作用,寻求一种高效可靠的评估绿色屋顶应用对城市流域径流影响的方法。以伊利诺伊州CDS-51流域为例,利用Matlab程序建立IUHM-GR(Illinois urban hydrologic model-green roof)组合模型,考虑不同绿色屋顶覆盖率,以及透水-不透水、不透水-透水、组合情况等不同径流方式的情况,分析了绿色屋顶的应用对流域径流的影响。结果表明:绿色屋顶具有较好的蓄滞效果,可有效削减流域径流总量和峰值,且绿色屋顶覆盖率比绿色屋顶径流方式对流域径流有更大的影响。

    Abstract:

    In order to make the green roof technology play an effective role in urban stormwater management, this paper seed an efficient and reliable method to evaluate the effect of green roof application on urban runoff. Taking calumet drop shaft 51(CDS-51)of Illinois as a case study, IUHM-GR(Illinois urban hydrologic model-green roof)combined model was established via Matlab, which considered different green roof coverage ratios and runoff conditions(pervious-impervious, impervious-pervious, and combined conditions)and analyzed the effect of green roof application on watershed runoff. The results show that the green roof has good water storage capacity and can effectively reduce the total runoff volume and peak value. Moreover, the green roof coverage ratio has a greater impact on runoff than the green roof runoff condition.
