住区低势绿地设计的关键参数及其影响因素分析

Critical parameters and influencing factors analysis on low elevation greenbelt in residential area

通过对低势绿地雨水量平衡及其影响因素的分析,讨论了低势绿地下凹深度、低势绿地面积负荷率、淹水时间等关键参数,提出了低势绿地的设计思想和设计方法,并对北京地区某住区实例进行了分析,为住区低势绿地设计提供了方法和依据。

Based on analysis of rainwater balance and influencing factors of greenbelt with low elevation, the critical parameters such as depth, area proportion and submerged duration etc. were discussed. The principle and method in design of low elevation greenbelt were put forward. Some examples of residential areas in Beijing were presented.
