西藏盐井盐泉地下热卤水水化学特征分析

地下水化学成分受地质、水文地质、岩性等因素的控制，水化学特征研究对水资源的利用、管理及保护具有重要的指导作用。西藏自治区芒康县盐井乡境内，沿澜沧江近岸边长约1．5km范围内出露有50余处矿化度较高、水温为中高温、无色、味咸的天然盐泉。这种地下热卤水的分布特征、水化学特征和化学组分的形成，受地质构造、地下水径流通道、径流速度等条件的影响，因此通过对其水样水化学特征的研究，进一步阐明盐泉形成的基本规律。

Study on Analysis of Thermal Brine Water in Yanjing County of Xizang

Chemical components of groundwater were formed by geoglogy,hydrogeology,lithology and other factors.The study of water resource were important to supervise utilization,management and protection of water.There were more than 50 natural salt springs giving off along the Lancangjiang river in Yanjing Town of Mangkang county,Xizang.The characters of distribution,hydrochemistry and chemical components of these brine water with high TDS were influenced by geological construction,track and speed of flow and so on.Therefore,this paper tried to clarify the basic rules and effective factors of salt spring by studying the hydrochemical characters.
