北京城市雨洪管理初步构想

城市化进程的加快使城市内产生了"水多"、"水少"、"水脏"等问题.单纯的建筑与小区雨水利用对设计标准内的降雨有很好的控制和利用效果,但对较大降雨和超标准降雨则难以应对.基于降雨产流、管网汇流和河道行洪的预报、监测与模拟的全面城市雨洪管理则是解决这一难题的重要措施.介绍了国内外城市雨洪管理的现状,针对北京城市雨洪管理存在的问题和不足,提出了北京城市雨洪管理的基本思路和需要进一步研究的关键问题,旨在推进北京城市雨洪管理的实施和"宜居城市"的建设.

Initial Concept of Stormwater and Flood Management in Beijing City

The acceleration of urbanization progress brings some water problems such as flood wa-ter, water scarcity, water pollution and so on. The rainwater harvesting measures in buildings and resi-dential areas have better effect on control and utilization of design storm. But it is difficult to deal with larger storm especially over-design storm. Therefore, it is necessary that an integral stormwater and flood management in the whole city should be established based on the prediction, monitoring and simulation of rainfall runoff, stormwater drainage network and flood river to solve this problem. Based on the current condition of Beijing City, the initial concept of stormwater and flood management and some key problems needing further study are put forward with a view to promote the implementation of Beijing City stormwater and flood management and the construction of livable city.
