摘要
为缓解城市内涝问题,从海绵城市角度出发,比较量化不同LID组合的效益。针对北京市的一个小区项目,利用暴雨管理模型(SWMM)以及层次分析法(AHP),分析了包含不同布置比例的生物滞留设施、草地、下沉式绿地、透水路面和蓄水池的3种方案。其中方案三在满足年总径流减少75%的条件下,提升了研究区雨水利用能力并且改善了景观效果。研究实现了不同LID设施的比例优选、综合效益优选,对促进海绵城市的发展进步具有参考意义。
The benefits of different low-impact development(LID) combinations are compared and quantified from the perspective of sponge cities to alleviate the problem of urban waterlogging.For a residential project in Beijing, the stormwater management model(SWMM) and the analytic hierarchy process(AHP) are used to analyze three different schemes with different layout scales of bioretention facilities, grassland, sunken green space, permeable pavements, and reservoirs.Among them, Scheme 3 improves the rainwater utilization capacity of the study area and the landscape effect under the condition that the total annual runoff is reduced by 75%.The research achieves the optimization of the ratio of different LID facilities and the optimization of comprehensive benefits, which is of referential significance for promoting the development of sponge cities.
