城市道路雨洪综合管理是目前国内外研究的热点问题.深圳市在低影响开发雨洪综合管理方面进行了有益的探索与实践,其应用已初见端倪.对比了低影响开发市政道路与传统市政道路在排水系统设计方面的差异,详细剖析了深圳市光明新区已建低影响开发市政道路示范工程,并对其径流量控制与污染物控制效果进行评估.结果表明,该道路在暴雨设计重现期为2年一遇的情况下,年降雨量的66%可入渗消纳,转化为地下水资源;道路雨量综合径流系数可降低至0.36.污染物控制方面,该道路径流污染物控制量达392立方米,雨水经绿化带植生滞留槽入渗后,其中的TSS、TN、TP、重金属等污染物可得到不同程度的削减.

Stormwater management of municipal roads is the hot issue around the world. Shenzhen has many explorations and practices on stormwater management in recent years, and Low Impact Development (LID) idea was applied to guide the urban stormwater management. In this paper, the difference between traditional stormwater design and LID design is contrasted. The LID municipal road demonstration projects is analyzes in detail. And the effects of runoff volume reduction and pol utants removel are evaluated. The results show that 66% of yearly precipitation can be infiltrated in 2-years rainfall, and the comprehensive runoff coefficient wil be reduced to 0.36. Pol utants control aspect, the stormwater treatment volume for non-point sources pol ution control is about 392m3, and the TSS,TN,TP and heavy metals can be removed in various degree.
