摘要 地下热水水质是地下热水的重要特征之一,也是地下热水资源评价的主要内容,其为制定地下热水合理开发利用方案提供重要依据。研究地下热水水化学组分形成作用一直是国内外水文地球化学的研究重点。利用R型因子分析法对咸阳市区地下热水水样的水化学数据进行分析,分析研究可知:咸阳市区南部热水起源成因复杂,水化学成分多样HCO3·SO4-Na、Cl·SO4-Na型为主。北部热流体水化学类型主要为Cl-Na型,纵向上随深度增加基本不变化,其主要发生的水化学形成作用有溶滤作用和脱硫酸作用,次为阳离子交替吸附、脱碳酸作用和石膏的溶解作用。 As a key feature of geothermal water, water quality is an important index for resource evaluation and proper ex- ploitation and utilization of geothermal water. Therefore, hydro chemical component formation of geothermal water is always a research priority in the study of hydro geochemistry home and abroad. The R - mode factor analysis method is used in this pa- per to analyze the hydro geochemical date of water sample taken from Xianyang. The result indicates that hydro chemical com- ponent of geothermal water in Xianyang is mainly affected by leaching and desulfurization aciding, while cationic alternate ad- sorption decarbonation and gypsum dissolution also happen in geothermal water.
