【摘要】 2021年，对太白山山顶大爷海，二爷海，三爷海和玉皇池四个冰川湖泊进行水样采集。通过Gibbs图、Piper三线图、主要离子比值法得出太白山冰川湖泊水化学成分的特点、水化学类型及其成因。结果表明：四湖泊水体均呈弱碱性，大爷海、三爷海和玉皇池湖泊的阳离子组成主要成分为Ca²⁺，阴离子组成的主要成分为-HCO₃^-，水化学类型为Ca（Mg）-HCO₃型湖泊；二爷海阳离子组成主要是Na⁺，阴离子组成的主要成分为-HCO₃^-，水化学类型为Na-HCO₃型湖泊。Gibbs图分析得出二爷海化学离子组成同时受岩石风化和大气降水的双重控制；而其余三湖泊主要受岩石风化作用控制。更多还原

【Abstract】 In 2021, water samples were collected at four glacial lakes of Taibai Mountain--Daye lake, Erye lake, Sanye lake and Yuhuangchi lake. The component characteristics, hydrochemical types and causes of water chemical composition of glacier lakes in Taibai Mountain were obtained by Gibbs diagram,Piper triangle diagram and main ion ratio method. The results show that the water bodies of the four lakes are weakly alkaline. The main cationic component of the Dadye lake, Sanye lake and Yuhuangchi lake is Ca²⁺, the main anion component of them is HCO₃^-,and the chemical types of the lakes is Ca（Mg）-HCO₃. The main cationic composition of Erye lake is Na+, and the main anion composition is-HCO₃^-, and the hydrochemical type is Na-HCO₃. The Gibbs diagram shows that the chemical ion composition of Eryehai is controlled by both rock weathering and atmospheric precipitation. The other three lakes are mainly controlled by rock weathering.更多还原
