摘要: 黑河源区河水水文地球化学特征的研究有助于了解黑河源区河水沿流域水质变化概况,对黑河源区生态环境的保护具有积极意义。以黑河源区干流为研究对象,对河水进行取样检测,结果显示:河水化学组成以K+、Na+、Ca2+、Mg2+和Cl-、NO3-、HCO3-、SO42-为主。通过聚类分析、舒卡列夫分类和Piper三线图分析发现主要离子中,阳离子主要来源于石灰岩风化产物,SO42-主要来源于蒸发岩矿物风化产物和人类活动,HCO3-主要来源于纯碳酸盐风化产物。通过对重金属污染调查发现,V、Co、Cu、Pb、Cr、Mn和Zn含量较高,矿山开采是重金属污染的主要来源。

Abstract: Research of the hydrogeochemistry in the source regions of the Heihe River is useful to search the basic changes in water quality along the river, and has positive significance for protecting the eco-environment in the regions. Through the previous researches, the lack of relevant background information about water quality in the source regions has improved. In this study, the source regions of the Heihe River are taken as the research object to understand the water quality of the river basin, through sampling and tasting the river water. The results show that the major chemical composition of the river water are K+, Na+, Ca2+, Mg2+ and Cl-, NO3-, HCO3-, SO42-. According to cluster analysis, Schukalev classification and trilinear diagram analysis, it was found that among the major ions, cations mainly comes from limestone weathering products, SO42- mainly comes from evaporating of mineral weathering products and human activities, and HCO3- mainly comes from pure carbonate weathering substances. Through heavy metal pollution surveying, it was found that the content of V, Co, Cu, Pb, Cr, Mn and Zn are much higher, and mine exploration is the main cause of heavy metal pollution.

Key words: Heihe River riparian areas, surface water, hydrogeochemistry, water quality analysis, cluster analysis
