| 中文摘要: |
| 以陕北红碱淖为研究对象，2020年6月对其湖泊水体选取9个采样点采样，分析阴阳离子的空间分布，并利用Piper三线图及离子比例关系分析离子来源及影响因素，探讨红碱淖水化学特征及其影响因素。结果表明：红碱淖水体阳离子测定值为Na+＞Mg2+ ＞Ca2+ ＞K+，阴离子测定值为HCO-3＞Cl-＞SO42-，水化学类型现状为HCO3·Cl-Na型，水化学特征主要受碳酸盐岩和蒸发盐岩共同作用。红碱淖主要受岩石风化溶解作用控制，人类活动对水化学特征也有一定的影响。 |
| 英文摘要: |
| Taking Hongjiannao Lake in northern Shaanxi as the research object, 9 sampling sites were selected for analyzing the spatial distribution of anions and cations in the lake in June 2020. The sources and influencing factors of the ions were studied according to Piper three line diagram and ion relations. The hydrochemical characteristics and influencing factors of Hongjiannao Lake were discussed. The results indicated that the concentration of cations in Hongjiannao Lake was Na+＞Mg2+＞Ca2+＞K+, and the concentration of anions was HCO-3＞Cl-＞SO2-4. The hydrochemical type was HCO3·Cl Na. The hydrochemical characteristics of Hongjiannao Lake were mainly affected by the weathering and dissolution of carbonate rocks and evaporites, human activities also had a certain influence effect. |
