摘要:: 为研究LID设施空间格局对径流控制和雨水径流污染负荷的影响，以雨水花园为例，采用SWMM构建的城市雨洪过程模型进行数值模拟，根据雨水花园在研究区汇水面上、中、下游区布设位置的不同来拟定优化方案，计算不同设计降雨重现期下雨水花园不同空间格局对径流调控和雨水径流污染负荷削减的提升效果。结果表明：①对于3种方案，径流总量控制率与设计降雨重现期呈负相关，将雨水花园布设在下游时，对径流总量控制率的提升效果最好；②在不同设计降雨重现期下，不同优化方案均对雨水径流污染负荷具有一定的调控效果，且雨水花园位于下游时对雨水径流污染负荷的净化效果最好，雨水花园对TSS和COD的削减效果整体要好于对NH₃-N和TP的削减效果。

Abstract:: To investigate the influence of LID facilities spatial pattern on runoff control rate and rainwater runoff pollution load, an urban stormwater process model established by SWMM was used for numerical simulation in a rain garden. According to the different locations of the rain gardens at the upstream, midstream and downstream of the catchment surface, the optimization schemes were formulated, and the effects of different spatial patterns of the rain gardens on the runoff control and rainwater runoff pollution load reduction under different return periods were calculated. For the three schemes, the total runoff control rate was negatively related to the return periods of the design rainfall, and the rain garden located downstream had the best improvement effect on the total runoff control rate. Under different design rainfall return periods, different optimization schemes had certain regulation effect on the rainwater runoff pollution load, and the rain garden located downstream had the best purification effect on the rainwater runoff pollution load. In addition, the reductions of TSS and COD were better than those of NH₃-N and TP in the rain garden as a whole.
