摘　　要：介绍了北京冬奥会延庆赛区水资源供需情况,并对水资源利用方案进行比选。基于完整年尺度的水资源分析显示,延庆赛区奥运年需从外部调水57.09×10^(4)m^(3),其中地表水47.11×10^(4)m^(3),自来水9.98×10^(4)m^(3);非奥运年需从外部调水16.35×10^(4)m^(3),全部为自来水。基于逐日分析的水资源利用方案显示,非奥运年再生水系统与融雪水、雨水系统分设方案再生水回用率仅为26.01%,远低于再生水、融雪水、雨水系统统一调蓄方案再生水回用率(56.85%),从水资源管控、景观环境营造、场馆运营等方面进行对比,再生水、融雪水、雨水系统统一调蓄方案对水资源的管理更为高效。This article mainly introduces the water resources supply and demand situation of Beijing Winter Olympic Games Yanqing zone,and comparably selects the water resources utilization schemes.The analysis of water resources based on the scale of the whole year shows that Beijing Winter Olympic Games Yanqing zone will need 570900 m-of water from the outside during the Olympic year,including 471100 m-of surface water and 99800 m-of tap-water.In the non-Olympic year,simply 163500 m-of tap-water will be diverted to the venues,which is enough to the requirement.Based on the daily analysis of water resources utilization planning suggestions,it shows that in the separate scheme,the reuse rate of the reclaimed water system,snowmelt water and rainwater system in the non-Olympic year is only 26.01%,which is far lower than 56.85%of the reclaimed water system,snowmelt water and rainwater system in the unified regulation and storage scheme.Therefore,from the perspective of water resources management,water environment construction and venue operation,a more effective unified storage and regulation scheme is proposed for the utilization of water resources.
