沙颍河流域水资源配置思路与计算模型EI北大核心CSCD

针对沙颍河流域水资源供需矛盾日益突出问题,根据沙颍河实际情况,提出了沙颍河流域水资源配置原则及流程,基于MIKE BASIN软件建立了沙颍河流域水资源配置模型,利用该模型对2015—2016年沙颍河流域河南段进行水资源配置计算。结果表明:水资源配置前,在生态流量保证率为100%的情况下,除中牟断面以上区间,其他区间均存在不同程度的缺水情况;根据模型水量配置结果,从颍河等处向郑州、开封等缺水城市调水的方案,可缓解流域河南段整体缺水状况,说明该模型可有效地进行水资源配置。

Thoughts and calculation model for water resources allocation in Shaying River Basin

In view of the increasingly prominent contradiction between supply and demand of water resources in the Shaying River Basin, according to the actual situation of the Shaying River, the principle and process of the water resources allocation in the Shaying River Basin are proposed, and the water resources allocation model is established based on MIKE BASIN software. The model is applied to water resources allocation in Henan section of the Shaying River Basin from 2015 to 2016. The calculation results show that under the ecological flow guarantee rate of 100%, except the upstream area of the Zhongmo control section, there are different degrees of water shortage in the ranges between other control sections before water resources allocation; according to the results of water resources allocation with the model, the scheme of water transfer from the Yinghe River and other rivers and reservoirs to Zhengzhou City, Kaifeng City, and other water-deficient cities can reduce the degree of water shortage in Henan section of the Shaying River Basin, demonstrating that the model is effective for water resources allocation.
