2012年7月21日,怀柔区遭遇到罕见的强降雨,城镇排涝系统建设和管理中的很多缺陷逐渐暴露出来。通过调查和研究,提出结论和建议:(1)应大力推进雨水就地资源化,控制城区积涝的源头;(2)应将雨水和地表水、地下水、中水纳入水资源统筹管理体系,同时在汛期将各类涉水工程设施统筹管理,共同为城镇排涝工作服务;(3)建议在新城规划建设中,建立并完善雨水资源化工程体系,实现区域水资源总量和地下水资源量的平衡。希望本研究能对中小城市和小城镇基础设施建设起到积极的作用。
On July 21, 2012, Huairou District experienced rare heavy rains. Many shortcomings in the construction and management of drainage systems in cities and towns have gradually been exposed. Through the investigation and research, conclusions and suggestions are put forward: (1) The source of rainwater should be vigorously promoted to control the source of waterlogging in urban areas; (2) Rainwater, surface water, groundwater and intermediate water should be integrated into the integrated management system of water resources, At the same time, all kinds of wading engineering facilities will be managed in flood season and serve as urban drainage work together. (3) It is suggested that a system of rainwater resources engineering should be established and perfected in the planning and construction of new towns, so as to realize the total amount of regional water resources and groundwater resources balance. It is hoped that this study can play an active role in infrastructure construction in small and medium-sized cities and small towns.
