随着北京市城市化的快速发展,城区硬化地面不断增加,在目前城市防洪基础设施相对滞后的情况下,城市防洪压力越来越大。同时北京市又严重缺水,解决这一矛盾就具有十分重要的意义。通过北京市丰台区近年来的探索和实践,证明了雨洪利用是解决这一矛盾的有效途径,其在提高城市防洪能力的同时,又能有效缓解水资源紧缺。下面从循环水务和建设节水型社会的角度,议城市防洪与雨洪利用的关系。
With the rapid development of Beijing’s urbanization, the hardened ground in urban areas has been continuously increasing. Under the current situation that the urban flood control infrastructure lags behind, urban flood control pressure is increasing. At the same time, Beijing is seriously lacking in water and solving this contradiction is of great significance. Through the exploration and practice in Fengtai District of Beijing in recent years, it is proved that the utilization of rain and flood is an effective way to solve this contradiction. It can effectively alleviate the shortage of water resources while improving the urban flood control ability. The following from the perspective of recycling water and building a water-saving society, the relationship between urban flood control and utilization of rainwater.
