摘要
为研究既有小区海绵化城市改造方案,以武汉市洪山区某既有小区为例,建立SWMM雨洪径流模型,根据场地条件、空间需求及下垫面特征的可行性分析确定不同LID组合方案,模拟了研究区域不同重现期下各组合方案径流控制和污染负荷情况,从生态、社会、经济三方面对各组合方案的模拟结果进行综合效益分析。结果表明,生物滞留设施的生态效益和社会效益较高;布设渗渠、植草沟和生物滞留设施的LID组合措施,对研究区域的径流控制、洪峰和污染物削减效果最好,社会效益和经济效益良好,为较优方案。
In order to study the sponge urban transformation scheme of existing communities, taking an existing community in Hongshan District of Wuhan as an example, a SWMM rainfall-runoff model was established. Different LID combination schemes were determined according to the feasibility analysis of site conditions, space requirements and underlying surface characteristics. The runoff control and pollution load of each combination scheme under different recurrence periods in the study area were simulated. The simulation results of each combination scheme were analyzed from the ecological, social and economic aspects. The results show that the ecological and social benefits of biological retention facilities were high. The combination of LID facilities for laying infiltration trench, vegetative swale and biological detention facility has the best effect on runoff control, flood peak and pollutant reduction in the study area, and has good social and economic benefits, which is the best scheme.
