西安市引汉济渭与黑河引水工程多水源联合调配模拟

目的]建立陕西省西安市引汉济渭与黑河引水工程多水源联合调配模拟模型,为西安市水资源可持续发展提供决策依据。方法]在分析西安市供水工程和用水户基础上,绘制水资源系统网络概化图,构建了多水源联合调配模拟模型,确定调配规则。通过典型年和长序列年法求解模型,得到不同来水频率情况下的多水源联合调配方案。结果] 2020水平年,来水频率分别为50%,75%和95%时,引汉济渭调水量分别占西安市需水量的39.74%,37.59%和35.33%;在特别枯水年,引汉济渭供生活用水达1.19×10~8 m~3,占西安市生活需水总量的36.28%。结论]计算结果表明,引汉济渭工程通水后,西安市水资源短缺局面得到缓解,调水量对保障西安市供水安全发挥了极大的作用。

Joint Operation Simulation of Multi Water Sources of Hanjiang River to Weihe River Water Transfer Project and Heihe River Diversion Project in Xi'an City

Objective] A simulation model of the multi-source joint allocation for the Hanjiang to Weihe River water transfer project and Heihe River diversion project of Shaanxi Province was established. This was aimed at providing a basis for the sustainable development of water resources in Xi''an City.Methods] Based on the analysis of the water supply project and the consumers of water in Xi''an City, the mixing rule was determined. This was achieved by constructing a network generalization map of the system of water resources and by building a simulation model of the multi-source joint allocation. Through a long series of calculations, the joint deployment scheme for different water supply frequencies was obtained.Results] In 2020, when the incoming water frequency will be 50%, 75% and 95% respectively, the water supply of the Hanjiang River will be 39.74%, 37.59% and 35.33%, respectively. In the special dry year, the water supply of the Hanjiang River was 1.19×10⁸ m³, accounting for 36.28% of the total water demand in Xi''an City.Conclusion] The water shortage in Xi''an City can be effectively alleviated by the implementation of the water diversion project, which has played a significant role in ensuring the safety of the water supply in Xi''an City.
