海绵城市建设下LID模拟研究综述及案例分析

Review and Case Analysis of LID Modeling Research for Sponge City Construction

低影响开发(Low Impact Development, LID)模式以自然水文、源头调控、分散管理的设计理念为核心,更加符合我国海绵城市建设的雨水管理战略.融合LID建模的城市雨洪模拟是海绵城市雨水体系建设的关键技术之一,然而现阶段针对LID模型设置和参数分析的研究十分有限.本文通过对近几年在主流期刊上发表的LID模拟文献进行汇总和梳理,选取6种常见LID模型进行模块分析和参数收集,旨在通过系统调研和综述,提供适用于不同地区LID模拟的数据支持.最后,选取两类相关的LID措施(绿色屋顶和透水路面),在研究区域实现了LID模型建立、雨水调控模拟和效能评估的目的.

Low impact development is taking the design idea of natural hydrology,source control and decentralized management as the core,which is more in line with the strategy of rainwater management for the sponge city construction.Urban storm simulation which contains LID modeling is one of the key technologies for the rainwater system construction of the sponge city.However,at the present stage,the research of the LID model setting and parameter analysis is very limited.By sorting and analyzing the LID simulation publishing in the mainstream literature and journals in recent years,six common LID models were selected for module analysis and parameter collection,aiming to provide data support for LID simulation in different regions through systematic survey and review.Finally,two kinds of related LID measures(green roof and permeable pavement)were selected,and the establishment of LID model,rainwater control simulation and effectiveness evaluation were realized in the research area.
