为充分发挥灰色基础设施与绿色海绵设施的协同作用，降低区域径流总量、提升生态环境质量与城市韧性，以陕西省西咸新区数据六路为研究对象，构建了透水铺装道路与生态沟渠耦合的灰绿结合排水系统，并利用SWMM软件，分别模拟传统开发和耦合系统在不同重现期(2 a、5 a、10 a、20 a、50 a)下雨水径流量及水质污染物的变化规律。结果表明：灰绿结合系统有较好的径流峰值削减与水质净化作用，径流峰值削减率依次为70.6%、54.2%、46.6%、40.6%、36.6%,道路径流系数分别为0.40、0.59、0.68、0.77、0.87,可以有效缓解城市内涝；同时在2 a一遇的低重现期下，灰绿结合系统对COD、SS、TP、TN的总量削减率依次为：87.68%、87.12%、89.77%、89.17%,浓度削减率依次为48.06%、55.34%、40.67%、42.13%,削减效果显著，与试验研究结果一致。研究成果能够为城市雨洪管理与防涝体系构建提供借鉴。
Abstract：To give full play to the synergy between grey infrastructure and green sponge facilities, reduce the total amount of regional runoff, and improve the quality of the ecological environment and urban toughness, we took the Shuju6′ road in Xixian new area of Shaanxi Province as the research object, and constructed a grey-green combined drainage system coupled with permeable paved road and ecological ditch, and used SWMM software to simulate the variation law of rainwater runoff and water quality pollutants of traditional development and coupling system in different return periods(2 a, 5 a, 10 a, 20 a, 50 a). The results show that the grey-green combination system has good effects on peak runoff reduction and water quality purification. The runoff peak reduction rates are 70.6%, 54.2%, 46.6%, 40.6% and 36.6% respectively. The road runoff coefficients are 0.40, 0.59, 0.68, 0.77 and 0.87 respectively, which can effectively alleviate urban waterlogging; At the same time, under the low recurrence period of 2 a, the total reduction rates of COD, SS, TP and TN by the grey-green combination system are 87.68%, 87.12%, 89.77% and 89.17% respectively, and the concentration reduction rates are 48.06%, 55.34%, 40.67% and 42.13% respectively. The reduction effect is remarkable, which is consistent with the experimental research results. The results can provide references for the construction of urban rainwater and flood management and waterlogging prevention system.
