摘　　要：雨水利用是解决城市发展过程中所产生的河道行洪压力增大、河湖被径流污染、积滞水易发等问题和缓解城市缺水局面的重要措施,在小区实施雨水利用措施后将对市政雨水管线的设计产生一定影响。基于对雨水利用示范工程多年的观测数据,分析了雨水收集存储回用、透水地面、下凹式绿地等雨水利用措施对雨水管线设计中径流系数、汇流时间等参数的影响。Rainwater utilization is a kind of solution to the problems, such as increased pressure of river flooding, non-point pollution in rivers and lakes, standing water in downtown, which are generated in the process of urbanization. It is also an important measure to relieve urban water shortage. The imple- mentation of rainwater utilization measures in subdistricts will produce certain effect on the design of mu- nicipal storm sewer. According to many years observation data in rainwater utilization demonstration engi- neering, the effect of different rainwater utilization measures, such as rainwater harvesting, storage and reuse, pervious pavement, and sunken greenbelt, on runoff coefficient, concentration time and so on for storm sewer design is analyzed.
