| 在快速城镇化进程中，由于硬质下垫面面积比例增
加，导致城市内涝问题日益突出。选取厦门市杏林湾地区作为
研究对象，以绿色经济与低影响开发为目标，运用SWMM技
术构建降雨-径流模型，分别对低影响开发前后的地块进行暴
雨重现期2年一遇和5年一遇情景的模拟，确定地块内涝易发
区域积水节点，根据节点位置布设低影响开发(LID)措施，以
此提高研究区对内涝灾害的承受能力。情景模拟结果为：杏林
湾选区在重现期2年一遇时，地块东部海湾口处容易出现内涝
现象；重现期5年一遇降雨导致杏林湾选区排水系统出现大范
围节点溢流，主要集中在湾区滨水空间及海湾口处。通过对易
涝区增设LID措施降低径流总量、削减洪峰小时流量，从而使
年径流控制率提升至77.5%，降低城市内涝灾害风险。 |

| Abstract: |
| In the process of rapid urbanization, the urban
waterlogging problem becomes increasingly prominent because the
ratio of hard underlying surface area increases. Taking the Xinglin
Bay block in Xiamen as an example, the rainfall-runoff model was
constructed by using the SWMM technology based on the principle
of green economy and low-impact development. The rainstorm
recurrence period for P=2a and P=5a conditions were simulated
for the plots before and after the low-impact development. It
determined the nodes of the rain-prone areas through the current
rainfall simulation. LID measures were deployed to alleviate surface
runoff according to the location of the rain-prone areas. The bay
mouth of the eastern part of Xinglin Bay are prone to waterlogging
in the Xinglin Bay district during the two-year recurrence period.
The rainfall occurs every five years in the recurrence period which
leads to the overflow of the drainage system for Xinglin Bay which
mainly concentrated in the waterfront space and the bay mouth. By
establishing LID measurements, the rate of annual runoff control
in the new area is increased to 77.5%, which is accompanied by
the reduction of the total runoff, the peak hourly discharge, the
rainstorm runoff coefficient and the risk of urban rainstorm and
waterlogging. |
