充分发挥河湖功能,保证北京市防洪排涝安全,强化水资源管理,保护水生态环境,是城市河湖管理的主要任务。根据长期观测的河湖水文资料及闸坝运行情况,制定河湖闸坝调度运行方案,非汛期按河湖供水、景观、治污等要求,控制河湖水位和特定河段流速,汛期根据雨情和水情,适时有序开启闸门,降低河湖水位,留足调洪容积,保证安全行洪并避免河水顶托排水管网。北京市水资源紧缺,要充分利用城市河湖适时拦蓄洪水,蓄积和输送再生水,缓和北京水资源供需矛盾。
Give full play to the functions of rivers and lakes, ensure the safety of flood control and drainage in Beijing, strengthen the management of water resources and protect the aquatic environment, which is the main task of urban river and lake management. According to the long-term observation of rivers and lakes hydrological data and sluice dam operation, the formulation of sluice dam operation plan, non-flood season according to river and lake water supply, landscape, pollution control and other requirements, control of river and lake water levels and river flow rate, flood season according to the rain And water conditions, timely and orderly open the gate to reduce the water level of rivers and lakes, leaving adequate flood control volume, to ensure safe floods and to avoid the top water drainage pipe network. Beijing water shortage, it is necessary to make full use of urban rivers and lakes timely block flood, storage and transportation of reclaimed water to ease the water supply and demand in Beijing contradiction.
