西藏冷曲河谷地区地下水资源合理开发利用研究

Study on rational development and utilization of groundwater resources in the Lengqu River Valley region of Tibet

地处西藏冷曲河谷地区的八宿县是连接西藏与四川主干线318国道重要城镇之一,水资源的匮乏成为制约该县经济发展的主要因素。通过地质调查、水文地质钻探等工作,查明西藏冷曲河谷地区松散岩类孔隙水和碎屑岩类裂隙水的含水层类型及分布特征,提出安全饮水、农业灌溉、乡镇水源地等供水方案和松散岩类、碎屑岩类地下水开发利用方案,对于科学合理开发地下水资源,缓解八宿县水资源短缺具有重要现实意义。

Basu County,located in the Lengqu River Valley in Tibet,is one of the important towns on the national highway 318,the main line connecting Tibet and Sichuan.The lack of water resources has become a major factor restricting the county′s economic development.Through geological surveys,hydrogeological drilling,and other work,the aquifer types and distribution characteristics of loose rock pore water and clastic rock fissure water in the Lengqu River Valley region of Tibet were identified.Water supply plans for safe drinking water,agricultural irrigation,township water sources,and the development and utilization of loose rock and clastic rock groundwater were proposed,which has important and practical significance for the scientific and rational development of groundwater resources and the alleviation of water resource shortage in Basu County.
