摘要

摘要: 建筑外环境低影响开发(LID)是实现城市高效径流控制与雨水资源利用的重要途径,但目前在LID设施布局时存在设施规模过大、径流利用效率低等建设浪费问题。基于建筑外环境径流特点,依据不同LID设施功能特征,耦合了SWMM模型与NSGA-II算法,构建兼顾径流控制、雨水资源利用率及LID设施成本的建筑外环境经济型低影响开发设计模式,以南阳一中校园为试验对象,运用该设计模式,获取其LID设施优化布局方案,并以2021年降雨模拟验证其径流控制与节水效果。模拟结果表明,在2021年降雨情景中实验对象LID设施优化布局方案的年径流控制率达82.0%,年可节约用水成本5.19万元。研究结果细化了LID设施布局应用场景,弥补了传统低影响开发设计方法对雨水资源利用、LID设施成本量化的缺失,有助于优化LID设施建设投资,推进我国"海绵城市"的高绩效、高质量建设。

Abstract: Low-impact development (LID) in the external environment of buildings is an important way to achieve efficient urban runoff control and rainwater resource utilization, however, there are some problems in the distribution of LID controls, such as excessive facility scale and low runoff utilization efficiency, which cause construction waste. Based on the runoff characteristics of the external environment of the building and the functional guidance characteristics of different LID controls, an economical design pattern of low-impact development in external environment of building was formed with SWMM model and NSGA-II algorithm, which took into account runoff control, rainwater resource utilization and cost of LID controls. Taking the campus of Nanyang No. 1 High School as the experimental object, the optimal distribution of LID controls was obtained by the design pattern, and its effect was quantified by simulation based on 2021 daily precipitation. The results showed that the annual runoff control ratio of the experimental object was 82.0%, and 51 900 yuan of water could be saved in 2021. The research results refined the application scenario of LID controls distribution, made up for the lack of traditional low-impact development that ignored quantification of rainwater utilization and LID controls cost, improved the optimization of the investment in LID controls construction, and promoted the high-performance and high-quality construction of "Sponge City".
