摘　　要：文章以福州市鼓楼区研究对象,分析了该区域道路系统的现状,计算了研究区域内排水管道的排水能力,针对现存道路及排水体系在排水方面的缺陷提出优化措施,并采用数值方法计算了采用优化措施对不同重现期下的雨水径流量和四种污染物的削减幅度。结果表明,采用优化措施后,研究区域在不同重现期下的降雨入渗量增加,地表径流量减少,雨水径流中悬浮颗粒、化学需氧量、总氮、总磷四种污染物的浓度显著降低。Taking Gulou District in Fuzhou City as the research object,this paper analyzes the current situation of the road system in this area,calculates the drainage capacity of the drainage pipeline in the study area,puts forward optimization measures for the defects of the existing road and drainage system in drainage,and uses numerical method to calculate the reduction amplitude of rainwater runoff and four pollutants under different return periods by using the optimization measures.The results shows that after adopting optimization measures,the rainfall infiltration in the study area increases under different return periods,the surface runoff decreases,and the concentrations of suspended particulates,chemical oxygen demand,total nitrogen and total phosphorus in rainwater runoff decreases significantly.
