下凹式绿地用于城市雨水径流控制浅析

Brief Analysis on Application of Low Elevation Greenbelt to Control Urban Rainwater Runoff

下凹式绿地是是基于源头控制的一种城市雨水低影响开发技术,对城市雨水径流有一定的蓄滞和净化效果。介绍了下凹式绿地的应用情况,归纳总结了其水文效应和净化效果,并对净化效果的影响因素进行了分析,以期为下凹式绿地的设计和提效提供参考。

Low elevation greenbelt is an urban rainwater low-impact development technology based on the source control, and has certain effect of retention and purification. This paper introduces the application of low elevation greenbelt, summarizes its hydrological effect and purification effect, and analyzes the impact factors of purification effect in order to provide the reference for the design and effect improvement of the low elevation greenbelt.
