- 結(jié)合低影響開發(fā)(LID)建設(shè)需求，從緩解城市洪澇風(fēng)險的角度出發(fā)，以典型城市區(qū)域萬泉河流域為例，基于InfoWorks ICM構(gòu)建綜合洪澇模型，參考北京市地方標(biāo)準(zhǔn)，在保持70%透水鋪裝占比不變的情況下，采用改進層次分析法開展下凹式綠地及雨水調(diào)蓄池的LID空間布局優(yōu)化研究。結(jié)果表明，LID措施能削減徑流、緩解內(nèi)澇。同時綜合考慮安全效益與經(jīng)濟效益，得到徑流總量平均削減率為41.70%、峰值流量平均削減率為40.16%、積水總量平均削減率為61.08%、積水面積平均削減率為56.74%、經(jīng)濟費用共計4.82 億元/a的“70%下凹式綠地+70%透水鋪裝+每千平方米硬化面積配建調(diào)蓄容積為30 m3的雨水調(diào)蓄池”優(yōu)化組合方案。
- 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.
