北京水资源严重紧缺,雨洪利用是减轻北京城市汛期防洪压力、缓解北京水资源紧缺的重要措施。北运河是北京唯一一条常年有水而且水量极为丰沛的河道,每年有大量的雨洪未能有效利用。探讨在确保城市防洪安全的前提下,充分利用雨水资源,创造优美的水环境。 Beijing is in a serious shortage of water resources and utilization of rainwater and floods is an important measure to alleviate flood control pressure in Beijing during the flood season and to ease the water shortage in Beijing. The Grand Canal is the only waterway in Beijing that is perennial with abundant water and abundant amounts of rainwater are not used efficiently each year. Under the premise of ensuring the safety of urban flood control, we should make full use of rainwater resources to create a beautiful water environment.
