中文摘要	运用水化学方法,通过对祖厉河这一黄河上游重要支流的多次实地考察和采样,结合区域水文地质条件,对祖厉河流域水体盐分的空间变化特征进行分析,并揭示流域水体的演化过程。结果表明,流域水体TDS普遍较高,总体以咸水为主。水中阳离子以Na~+为主,阴离子则以Cl~-、SO_4~(2-)为主。水化学类型方面,源区地下水以Mg-Ca-Na-HCO_3型水为主,河水则以Na-Mg-Cl-SO_4型水为主。流域内水体盐分主要来源于阳离子交替吸附作用、上游地下水淋滤地层盐分后以泉的形式向河流排泄以及河流径流过程中侵蚀两岸高盐分土壤或含盐地层。径流过程中,当地干旱的气候环境使水体进一步蒸发浓缩,这是流域内水体TDS进一步增高的外在水化学演化过程。总之,由于多种来源的盐分,特别是源区高TDS地下水排泄、流域内强烈的土壤侵蚀以及干旱的气候条件等多重作用过程,是祖厉河TDS显著增高失去水资源功能的主要机制。
英文摘要	The hydrochemical investigation and sampling were carried out in the Zuli River,one of the tributaries in the upper Yellow River.This paper analyzed the spatial distribution characteristics and evolution process of the salty water in the Zuli River Basin.The results show that the TDS of the water body in the Zuli River Basin is generally high,and the water is salty.The hydrochemical types of groundwater samples from the source area are dominated by the Mg-Ca-Na-HCO_3.River samples are highly mineralized and dominated by the Na-Mg-Cl-SO_4 type.The high salinity in the Zuli River Basin is characterized of the cation exchange and absorption,the groundwater discharge into the river after leaching salt stratum in the upstream,and eroding the soil salts in both sides of the river.During the runoff process,the arid climate makes the water body further evaporating and concentrating,which is the external hydrochemical evolutionary process of the TDS further increasing in the catchment.In short,the multiple sources of salinity,especially the high TDS groundwater discharge of the source area,the strong soil erosion and arid climate in the basin,are the main reasons causing the loss of water resources function and the significant increase of TDS.
