基于低影响开发的城市园林绿地雨水管理系统新常态

New Normal Of Stormwater Management System To Urban Green Space Based On Low-Impact Development

针对传统城市绿地规划中着眼于景观化和服务游人功能化,城市雨洪、水污染却被忽略的问题,将LID(低影响开发)应用于城市绿地规划中,改变现状,建设海绵城市。LID技术是能够快速实现城市雨水的收集、净化和再利用的生态技术体系,是一种通过对源头进行分散控制的雨水管理实践形式。基于LID技术,分别将雨水源头控制、雨水过滤处理以及雨水的储存再利用同植物群落截留、透水铺装与绿色停车场、雨水花园和调蓄池等绿地规划的方法和技术相结合,形成以LID为技术支撑,以园林设计方法为依托。

In term of the issues lied in the traditional urban green space planning emphasized the site＇s landscape and functionality, urban rainfall flood and water contamination were neglected, low impact development（LID） will be used in urban green space planning to change the actuality and then to build the sponge city. LID is a ecological technology system which can quickly gather, purify, reuse the urban rainwater. It＇s also a practice case of rainwater management via distributed control of the source. Combining source-control, rainwater filtration, rainwater collected and stockpiled with plants interception, permeable pavement, green parking lot, rain garden, detention tank based on LID, and developing the new normal of rainwater management system in urban green space closed to natural hydrological cycle, which is supported by LID and based on garden design methods.
