摘要
选取绿色屋顶的组成部分作为研究对象,探究不同植物、新型土壤种类、土壤层厚度的参数组合对绿色屋顶单体的径流量削减影响。通过实验发现,采用蛭石与泥炭土3∶1混合而成的土壤层厚度为50 mm的参数组合的径流量削减效果比珍珠岩与泥炭土3∶1土壤层厚度为150 mm的实验组合更好。同时以沭阳市某小区为研究区域构建SWMM模型,模拟不同重现期该绿色屋顶对居民区的径流量削减效应。结果表明绿色屋顶能削减洪峰流量,推迟峰现时刻。
The components of green roof was selected as the study object and this paper investigated the effects of parameter combination among different plants, new soil types and the thickness of soil layer on runoff reduction of green roof monomer. It was found through experiments that the runoff reduction effect of the parameter combination of vermiculite and peat with 3： 1 and 50 mm thick was better than that of perlite and peat with 3： 1 and 150 mm thick. Meanwhile, an area of Shuyang city was taken as the research area to construct the SWMM model. It simulated the effects of the green roof on runoff reduction in residential areas during different recurrence periods. The results showed that the green roof could reduce the peak discharge and delay the peak time.
