基于低影响开发的清华学堂路雨洪管理与景观设计研究

Storm-water Management and Landscape Design Research on Xue Tang Road of Tsinghua Campus based on the Low Impact Development Technology

低影响开发强调通过源头控制保障城市水文循环。随着"海绵城市"建设的推进,LID在城市雨洪管理的应用日益受到关注。城市雨洪模拟技术作为城市防洪减灾关键技术之一,可以有效的模拟并预期暴雨来临时研究区域的雨洪情况。基于SWMM雨洪模型,设计了清华大学学堂路区域的LID措施,对比分析增设LID措施前后径流量及蓄水量的变化,并探讨了高密度校园环境下雨水链景观系统构建的策略。

Low impact development raises that maintaining the urban hydrologic cycle by source control. With the widely spread of ＂sponge city＂ construction, increasingly attention was paid to LID in the application of urban rain flood management. As one of the key technology in urban flood prevention, storm-water simulation technology could effectively simulate and forecast the rain flood situation of target area when heavy rainning comes. This study has designed the LID measures for Tsinghua campus as well as the Xue Tang Road area, and adopted SWMM model to establish their rain flood model, aiming at comparing the change of storage capacity and the runoff before and after utilizing LID measures and exploring how the LID practices work on Tsinghua campus storm-water management.
