摘　　要：为评估透水路面对提高科技园区防洪排涝能力的影响,助力海绵科技园区建设,本文应用低影响开发理论,通过建立沧州中欧绿色产业园SWMM模型,研究了透水路面对研究区域径流水量与水质的影响规律。结果表明,设置透水路面后,降雨设计重现期为1年时,径流总量、峰值流量以及TP和TN两种污染物浓度总量和浓度峰值削减率均较高,但是随着设计重现期的提高,径流量及污染物浓度的削减效果逐渐降低;路面阻塞对透水路面发挥渗透能力有较大影响,研究成果可为透水路面的设计及运维提供理论参考。In order to evaluate the influence of permeable pavement on improving the flood control and drainage capacity of science and technology park,and to help the construction of sponge science and technology park,this paper applies the low-impact development theory and establishes the SWMM model of Cangzhou Zhongou Green Industrial Park to study the influence law of permeable pavement on runoff quantity and water quality in the study area.The results show that when the design return period of rainfall is one year after setting permeable pavement,the total runoff,peak flow,the total concentration and peak concentration reduction rate of TP and TN are higher,but with the increase of design return period,the reduction effect of runoff and pollutant concentration gradually decreases.Pavement blockage has a great influence on the permeability of permeable pavement.The research results can provide theoretical reference for the design and operation of permeable pavement.
