许昌市水资源多模式联合调度与合理配置

水资源短缺是制约城市经济社会发展的重要因素,合理配置和有效利用有限的水资源是解决水资源供需矛盾的有效途径。以许昌市国家水生态文明试点城市建设为例,在分析水资源开发利用现状的基础上,运用定额法对需水量进行预测。以多年平均水资源量为基础,2011年作为研究基准年,根据水资源取用方式、工程方案及各种水量需求等,利用MIKE BASIN建立水资源配置模型,对许昌市水资源供需平衡进行模拟,通过三次供需平衡分析,得到不同规划水平年水资源供需配置方案,最终达到水资源供需平衡,使有限的水资源发挥最大效益。研究结果表明,本地水资源结合南水北调、引黄调蓄、中水回用等多模式联合调度,可以满足许昌市中长期经济社会可持续发展用水需求,对未来许昌市水资源可持续利用具有重要的指导意义。

Multi-mode joint operation and rational allocation of water resources in Xuchang City,Henan Province

Water resources shortage is an important factor restricting the economic and social development of the city. Rational allocation and effective use of limited water resources is an effective way to solve the contradiction between water supply and demand. Xuchang City is taking as an example for national water ecological civilization city construction in this paper. The water demand is forecasted by the quota method according to the analysis of the status of water resources development and utilization. Based on the multi-year average water resources, 2011 is taking as the research base year. According to the water resources access, engineering scheme and various water demands, etc. MIKE BASIN is used to establish the water resources allocation model. The water supply and demand balance is simulated in Xuchang City. The water supply and demand allocation is obtained in different planning levels through three times of supply and demand balance analysis program, and ultimately to achieve water supply and demand balance, so that the limited water resources can maximize efficiency. The research results show that the local water resources can be combined with the multi-mode joint operation of South-to-North water diversion, Yellow River water diversion and reclaimed water reclamation to meet the water demand of Xuchang City in the medium-long term sustainable economic and social development. It also has significance guide for the future sustainable utilization of water resources in Xuchang City.
