| 摘 要： | 针对低影响开发(LID)措施可有效削减洪峰流量和污染负荷,对降低洪涝灾害风险、保护生态环境具有重要作用,但其补偿机理尚不明确的问题,基于SWMM模型,采用控制变量法分别计算了不同大小的渗渠LID措施和相应透水率。结果表明,渗渠LID措施的补偿效果随渗渠LID措施的增大而增大,且渗渠LID措施大小与透水率之间存在定量补偿关系,可确定其补偿效果,为渗渠LID的布设提供了依据,也为LID措施的进一步发展提供了一种新思路。

| Abstract: | Although low impact development (LID) measure can shave peak discharge and reduce pollution load effectively and plays an important role in reducing the water logging risk and protecting ecological environment, their compensation mechanisms are still unclear. Based on SWMM model, control variable method is adopted to calculate permeability LID channel measures with different sizes and the corresponding permeable rate. The results show that the compensation effect of permeability channel LID measures improves with increase of permeability channels measures; there is a certain quantitative relationship of compensation between the size of the seepage drainage and permeable rate so as to determine the compensation effect. Therefore, it provides the basis for permeability channel layout and an new idea for further development and application of LID measures. |
