摘要
以合肥市某工业园区部分区域为对象,研究LID措施对雨洪的消减效果。采用SWMM模型模拟分析了绿色屋顶和下沉式绿地措施中的敏感参数最佳取值范围,LID措施之间的影响。研究结果表明:绿色屋顶的土壤厚度控制在105~135mm效果最佳;下沉式绿地的表面层深度=110mm,土壤厚=290mm时接近最佳值;上游LID措施会持续促进下游LID发挥更大作用。
Based on an industrial park in Hefei, the effect of LID measures on rain flood reduction was studied. The range of sensitive parameters of green roof and sunken green belt, the influence of LID facilities, the transformation mode of reservoir and the relationship between reservoir volume change and other LID scale were discussed by SWMM model simulation. The results showed that the better soil thickness of green roof was controlled at 105~135 mm. The better surface layer depth and soil thickness of submerged green space were controlled at 110 mm and 290 mm. Upstream LID measures promoted downstream LID to play a greater role.
