摘要
夏德日河是泽曲河的支流,是青海省泽库县县城附近重要的河流。地下水做为水资源不可或缺的一部分,在保障城镇居民生活与生产用水及支撑社会经济发展中发挥着重要作用。本文以泽库县夏德日河河谷(县城段)为研究对象,通过水文地质、物探、水文地质钻探及样品采集测试等工作,基本查明了夏德日河河谷(县城段)水文地质条件,计算分析了地下水天然资源量及可开采潜力,为该地区地下水资源开发利用提供基础数据。经计算,夏德日河东河谷县城段松散岩类孔隙潜水地下水天然资源量为9441 m^(3)/d,夏德日河西河谷县城段地下水天然资源量为1907 m^(3)/d。夏德日河东河谷县城段地下水可开采资源量为3577.8 m^(3)/d,矿化度0.339 g/L,水质好,水量丰富,开采量有保证,可作为县城的后备水源。该评价思路对该地区其他河流地下水资源量的评价具有参考价值。
The Xiaderi River is a tributary of the Zequ River and an important river near the Zeku County,Qinghai Province.As an indispensable part of water resources,groundwater plays a vital role in ensuring the living and production water supply for urban residents and supporting social and economic development.Taking the Zeku County section of the Xiaderi River Valley as the research object,through hydrogeological geophysical prospecting,hydrogeological drilling,and sample collection and testing,this paper investigates the hydrogeological conditions,calculates and analyzes the natural resources and exploitable potential of groundwater in,and provides basic data for the development and utilization of groundwater resources in this area..According to the calculation,the natural resource amount of phreatic water in the pore of loose rocksthe eastern Xiaderi River Valley of county section is 9441 m^(3)/d,and that in the western Xiaderi River Valley of county section is 1907 m^(3)/d.The exploitable resource amount of groundwater in the eastern Xiaderi River Valley of county section is 3577.8 m^(3)/d,with a salinity of 0.339 g/L.The water quality is good,the water quantity is abundant,and the exploitation quantity is guaranteed,which can serve as the backup water source for the Zeku county.This evaluation idea has reference value for the evaluation of the groundwater resource of other rivers in this region.
