引汉济渭工程受水区供用水过程分析

Study on the Water Supply and Water Use Processes in the Benefited Areas in Water Diversion from Han River to Wei River Project

引汉济渭工程是陕西省为了解决关中地区缺水问题而规划建设的跨流域调水骨干工程。本文在社会经济发展分析基础上,对受水区水量需求结构进行了分析;并以旬为时间单位,对受水区生活、生产等用水过程进行了分析。在1955年至2007年系列年供水区可调水量及其它当地水源供水量基础上,对受水区供水过程进行了分析。由分析可知,为协调供水与用水过程不匹配问题,建设引汉济渭配套的调蓄工程成为必然选择。

Water Diversion from HanRiver to Wei River Project is an important water diversion project constructedto solve the shortage of water resources in the Guanzhong Area of ShannxiProvince. This study analyzes the water resources demand structure of thebenefited areas based on the analysis of social and economic development.Taking a period of ten days as the time scale, this study analyzes the wateruse process including the domestic water use and production water use. Based onthe time series from 1955 to 2007, this study analyzes the water supplyprocess, the water diversion quantity and regional water supply. It is knownfrom this study that a regulation project as a supplement of the waterdiversion project is necessary to coordinate the processes of water supplyand water use in the benefited areas in water diversion from Han River to WeiRiver Project.
