摘　　要：在柴达木格尔木河流域,随着内陆流域水系的产生与地表径流的消亡,从山区至盐湖区钾(K)硼(B)锂(Li)等有益元素的分布可以划分为淋溶-径流区、径流-蒸发区与溶滤-蒸发浓缩富集区3个具有显著特点的水文化学分带。河水中,K、B、Li含量随矿化度升高而升高,且呈正相关关系。在盐湖区,K、B、Li等资源性元素明显富集。研究发现,格尔木河东部主流(秀水河)是格尔木河水中B和Li的主要贡献者。In the Qaidam Golmud River drainage area,with appearance of the inland river system and disapearance of surface runoffs,the distribution of potassium（ K）,boron（ B）,lithium（ Li） and other beneficial elements from the mountains to the Salt Lake area,along the Golmud River can be divided into three distinctly hydrogeochemical zones： leaching-runoff zone,runoff-evaporation area and filtration-evaporation enrichment zone. The contents of K,B and Li in river waters increase with increasing salinity and there are positive correlations among these elements. The river waters at saline lake area are remarkably enriched in K,B,Li and other resource elements. It is found that the Xiushui River of eastern mainstream of Golmud River is the major contributor to B and Li in waters of Golmud River.
