基于InfoWorks ICM模型的城市小区LID组合方案成本效益研究
Cost-effectiveness of LID combination schemes for city area based on Info Works ICM model
摘要
Abstract
In response to the problem of cost and benefit imbalance in the construction of low impact develop-ment(LID)rainwater systems,a residential area in Tianshui City,Gansu Province was selected as the re-search area to construct an InfoWorks ICM one and two dimensional coupled model.The total runoff control rate,peak runoff reduction rate,water accumulation area reduction rate,water accumulation reduction rate,suspended solids(SS)reduction rate and chemical oxygen demand(COD)reduction rate of different LID combination schemes under different rainfall return periods were quantitatively analyzed for the study of cost-ef-fectiveness of LID facilities,with the consideration of their life cycle cost.The results show that the LID com-bination scheme with green roof is less cost-effective,but it has a strong adaptability to heavy rainfall,and is more suitable for rainstorm prone areas.The LID combination schemes are highly cost-effective in reducing the area and volume of water accumulation,and can effectively alleviate waterlogging;however,the cost-effective-ness of COD reduction rate is relatively low,and further optimization is needed.The combination of rainwater buckets,biological retention facilities and permeable paving,as the most cost-effective solution,is more suit-able for the construction of LID rainwater systems in the study area.The research results have important refer-ence significance for the optimization design of LID rainwater systems.关键词
