城市道路与雨水利用

通过分析城市化对城市水文系统的影响,指出城市排水不利是产生城市洪涝灾害的主要原因,给出城市道路建设和城市雨水蓄集联合运用的模式。通过城市道路,充分利用由于城市发展而增加的地表径流,不仅可以减小暴雨洪峰流量,减轻市政排水压力,解决道路积水和城市防洪、排涝等问题,还可以控制径流污染,缓解城市水危机,改善城市生态环境,从而实现道路建设和水资源的可持续发展利用。

Urban Road and Rainwater Utilization

The paper analyses these influence,points out that utilization and urban unsuccessful rainwater drainage system results in the flood disaster occur,and gives a connection method of urban development with rainwater utilization.By urban road,surface runoff are effectively utilized which has been increased by urbanization,can not only reduce the storm water runoff,decrease the pressure of drain,resolve the problem of road accumulated water,and control flood etc,but also can control the runoff pollution,alleviate the water crisis,improve the ecosystem environment.Thus,both sustainable development of road construction and water resource use have been realized.
