随着城市化的快速发展,城市面临的洪涝灾害和水资源匮乏等共性问题日益严重。本文采用暴雨管理模型 SWMM 对研究场地水文效应进行评估,模拟了不
同绿色雨水基础设施 GSI 单独布置和组合布局对削减场地暴雨径流的影响。研究表明,在场地尺度上,GSI 对降低地表径流,缓解峰值流量均有一定的作用,但
受到用地规模等因素的限制,GSI 虽然能起到一定的控制雨水径流作用,但对径流量的削减能力随着设计降雨重现期的增大而减小,需要同雨水管网等灰色基础
设施统筹协调。经过参数率定建立的场地 SWMM 模型可辅助进行不同 GSI 布局方案水文效应的评估比选,从而为场地空间的布局优化提供依据。 |

Abstract: |
Flooding and short of water resources is becoming more and more serious problem because of fast urbanization. In situational analysis, four layout
of Green Stormwater Infrastructure(GSI) were put forward by evaluating their hydrology using Storm Water Management Model(SWMM). It is proved that GSI
such as green roof and water garden can be used to reduce runoff of stormwater and increase storage capacity of rain. But their performance is still limit so that
should be combined with drainage system. Also SWMM can help to optimize the layout of GSI. |
