海绵城市建设LID技术方案优选研究——以徐州某高校区域为例

Study on the optimization of LID technical scheme for the construction of sponge City——University in Xuzhou for an Example

本文首先归纳了以往研究人员在LID技术方面的成果,分析现有技术存在的问题。结合现有的技术指南,使用Topsis工具建立LID技术方案优选模型。为了达到同步验证的目的,笔者采用徐州某高校区域数据进行应用研究,比选了4个LID技术方案。在比较中,作者综合考虑了技术方案在径流参数方面和预算指标方面的优劣程度,得出了最优方案,优选结果与之前成果保持一致,即最优方案可以明显改善溢流和内涝情况,方案经济可行。

For studying the optimization design methods of LID technology, the author first summarized the previous researchers＇ achievements in LID technology. Combining existing technical guidelines, the LID technology optimization model was established by using the Topsis Method. For achieving the purpose of verification at the same time, the author used the empirical data of a university in Xuzhou to study and compare 4 LID technology solutions. In these comparisons, the author comprehensively considered the degree of the technical scheme in terms of runoff parameters and budget indicators; the preferred result is consistent with the previous results; that is to say, the optimal scheme can obviously improve the overflow and waterlogging situation, and is optimal in the engineering economy.
