雨洪利用是缓解首都缺水局面、减轻城市沥涝威胁和防洪压力、改善水生态环境的一项重要措施。中德合作“北京城区雨洪控制与利用技术研究与示范”项目已经针对北京市的特点,在学习和借鉴国外先进技术和经验的基础上,较系统地开展了相关的研究,并建设了代表5种类型、小区总面积达60hm2的6个雨洪利用示范区。这些示范区在建成之后、特别是在2004年7月的3场特大暴雨中发挥了重要作用,在削减径流、增加可利用水量、补给地下水、改善社区环境等方面表现出良好的效果,深受广大居民的好评。社会各界纷纷到示范区参观学习,这为雨洪利用在全北京市的推广应用奠定了理论、技术和社会基础。为了从政策上支持雨洪利用的推广应用,北京市于2003年3月颁布了《关于加强建设工程用地内雨水资源利用的暂行规定》,提出了实施雨洪利用措施可申请减免防洪费的鼓励政 Flood and flood utilization is an important measure to alleviate the water shortage situation in the capital, reduce the urban flood and waterlogging threat and flood control pressure, and improve the aquatic environment. Sino-German cooperation “Beijing Urban Rainfall Control and Utilization Technology Research and Demonstration” project has targeted Beijing’s characteristics, learning and drawing on advanced foreign technology and experience on the basis of a more systematic study carried out and the construction of a representative 5 types, 6 honghong district of total area of ​​60 hm2 use of the demonstration area. After their completion, these demonstration zones played an important role especially in the three torrential rains in July 2004 and showed good results in reducing runoff, increasing available water, replenishing groundwater and improving community environment. The majority of residents praise. All walks of life have visited the demonstration area to visit and study, which laid the theoretical, technical and social foundation for the popularization and application of rainwater utilization in all Beijing. In order to support the popularization and application of rainwater utilization from a policy perspective, Beijing Municipality promulgated the Provisional Regulations on Strengthening the Utilization of Rainwater Resources in Construction Land for Construction in March 2003, and proposed the encouragement that rainwater utilization measures can be applied to reduce or prevent flood damage Politics
