摘要
随着各地海绵城市建设的推进,模型评估在海绵城市低影响开发设计中得到广泛运用,准确的LID设施模型参数确定是其应用可靠的关键性问题。以厦门海绵城市试点建设为契机,采用Morris分析方法,对SWMM模型中的几类LID设施模型参数进行敏感性分析。研究结果表明,表面粗糙系数对于植草沟设施而言是高敏感参数,土壤导水率对于绿色屋顶、生物滞留池设施而言是高敏感参数,土壤导水率和表面粗糙系数对于透水铺装设施而言是高敏感参数。
With the advancement of sponge city construction in various cities, model evaluation has been widely used in the low-impact development design of sponge cities. Accurate LID facility model parameter determination is a key issue for its application reliability. Taking the Xiamen sponge city pilot area as an example, this paper uses the Morris analysis method to analyze the sensitivity of several types of LID facility model parameters in the SWMM model. The results show that the surface roughness is a highly sensitive parameter for the planting ditch facility. The soil hydraulic conductivity is a highly sensitive parameter for green roof and bioretention pond facilities. The soil hydraulic conductivity and surface roughness are for permeable paving facilities. It is a highly sensitive parameter.
