摘要
以河南省巩义市某待建海绵生态小区为研究对象,运用SWMM软件,借用边际效益和成本效益分析方法,进行山地小区低影响开发(LID)设施组合比例的研究。结果表明:从边际效益递增的规律来看,可以提高下凹式绿地和透水铺装的比例,但在下凹式绿地率较高(60%)时,透水铺装率不宜超过70%;在实现相同的综合雨量径流系数和峰值流量削减率时,可能存在多种LID设施组合,存在成本优化的必要性;LID设施的优化组合是透水铺装率为60%与下凹式绿地率为60%的组合。
The composition ratios of low impact development ( LID) facilities in a mountain district were studied by using storm water management model ( SWMM ) and marginal and cost benefit analysis method in a planned sponge ecological district of Gongyi, Henan Province. The results indicated that the proportion of sunken lawn and permeable pavement could be improved from the law of increasing marginal benefit. However, the proportion of permeable pavement should not exceed 70% when the proportion of sunken lawn reached a high level ( 60%). There were several sets of LID combinations which could achieve the same integrated pluviometric runoff coefficient and peak flow reduction rate, so it was necessary to optimize the cost. The optimal composition of LID facilities was sunken lawn rate of 60% and permeable pavement rate of 60%.
