| 本文基于低影响开发理念及海绵城市建设,以河南省扶沟县城南新区作为研究区域,采用SWMM模型,研究分析了雨水涵养池在不同上下游区域、不同布设密度和不同降雨重现期的情况下,其对雨水径流的调控效果和污染物的削减作用,并通过对比分析后确定空间布局最优方案。结果表明相同降雨重现期和布设密度时,雨水涵养池布设在上游区域对污染物削减效果明显,排放口洪峰削减大;并且相同降雨重现期,涵养池布设在上游区域时,其分布越分散,污染物和洪峰的削减效果越好。 |
| 英文摘要: |
| Based on the low impact development concept and the construction of sponge city, this paper takes the Chengnan New District of Fugou County,Henan Province as the research area,and uses SWMM model to study the the effect of Rainwater Conservation Ponds(RCPs) on the regulation of rainwater runoff and the reduction of pollutants under several scenarioes of different regions,layout densities and rainfall return periods.As a result,the optimal space layout case of RCPs is determined through comparative analysis and scenario simulation. The result shows that when the rainfall return periodkeeps constant,it is better to reduce pollutants and flood peaks for RCPs arranged upstream area than downstream area.At the same time,it is also indicated that the more dispersed the distribution of RCPs in upstream area,the more obvious effect of reducing pollutants and flood peak. |
