- 摘要:
- 结合低影响开发(LID)建设需求，从缓解城市洪涝风险的角度出发，以典型城市区域万泉河流域为例，基于InfoWorks ICM构建综合洪涝模型，参考北京市地方标准，在保持70%透水铺装占比不变的情况下，采用改进层次分析法开展下凹式绿地及雨水调蓄池的LID空间布局优化研究。结果表明，LID措施能削减径流、缓解内涝。同时综合考虑安全效益与经济效益，得到径流总量平均削减率为41.70%、峰值流量平均削减率为40.16%、积水总量平均削减率为61.08%、积水面积平均削减率为56.74%、经济费用共计4.82 亿元/a的“70%下凹式绿地+70%透水铺装+每千平方米硬化面积配建调蓄容积为30 m3的雨水调蓄池”优化组合方案。
- Abstract:
- Combining the need of low impact development (LID) construction and mitigating the risk of urban flooding, an integrated flood model based on InfoWorks ICM was constructed by taking a typical urban area—the Wanquan River watershed as an example. With reference to the local standards of Beijing, the proportion of 70% permeable pavements was kept unchanged, and LID spatial layout of sunken green land and rainwater storage tank were optimized by using improved analytic hierarchy process. The results showed that the LID measures could reduce runoff and mitigate waterlogging. At the same time, the security and economic benefits were comprehensively considered, and the optimized combination scheme was obtained, which was “70% sunken green land + 70% permeable pavement+ rainwater storage tanks with a volume of 30 m3 per thousand square meters of the impervious areas”. After implementation of the optimized combination scheme, average reduction rate of total runoff volume was 41.70%, average reduction rate of peak flow was 40.16%, average reduction rate of total water volume was 61.08%, average reduction rate of the waterlogging area was 56.74%, and economic cost was 482 million yuan per year.
