摘　　要：漳河是海河南系的主要支流之一,也是京津冀地区的主要水源之一,了解漳河流域水化学特征对于海河流域水资源管理和京津冀地区的社会发展具有重要意义。本研究综合利用图解法分析了漳河上游地区地表水水化学特征及其主要影响因素,从水化学角度阐述了该区域水循环过程,并揭示了研究区水体主要离子来源。结果表明:①漳河上游地区地表水中的4种主要阳离子浓度由高到低分别为Ca^(2+)、Mg^(2+)、Na^(+)、K^(+),4种主要阴离子的浓度由高到低分别为HCO_(3)^(-)、SO_(4)^(2-)、Cl^(-)、NO^(-)_(3);②漳河干流和清漳河的水化学类型以HCO_(3)-SO_(4)-Ca-Mg型为主,浊漳河流域水化学类型表现出了明显的混合特征,浊漳河南源水化学类型为HCO_(3)-SO_(4)-Na-Ca型,西源水化学类型为HCO_(3)-Na-Ca型,北源水化学类型从HCO_(3)-SO_(4)-Ca-Mg型转换为HCO_(3)-SO_(4)-Cl-Na-Mg型;③水岩作用、阳离子交换以及人类活动影响了漳河上游地区水离子特征;此外,不同区域径流汇集也对流域水化学特征产生了重要影响。研究发现,水岩交互是漳河上游水体演化的重要过程。因此,关注山区岩溶过程对于流域水资源精准评估具有重要意义。Zhanghe River is one of the main tributaries of the Haihe River system and one of the main waterheads in Beijing-Tianjin-Hebei region.Understanding the hydrochemical characteristics of Zhanghe River Basin is of great significance to water resources management of Haihe River Basin and social development of Beijing-Tianjin-Hebei region.In this study,the characteristics of surface water hydrochemistry and its main controlling factors in the upper Zhanghe River area were analyzed by using a comprehensive graphical methods,and the hydrological cycle process in the region was described from the view of hydrochemistry,and the main sources of ions in the water bodies in the study area was revealed.The results showed that the concentrations of four major cations from high to low in surface water in the upper reaches of the Zhanghe River were Ca^(2+),Mg^(2+),Na^(+),K^(+).The concentrations of four major anions from high to low were HCO_(3)^(-),SO_(4)^(2-),Cl^(-),NO_(3)^(-).The hydrochemical type of the main stream of the Zhanghe River and the Qingzhanghe river was HCO_(3)-SO_(4)-Ca-Mg.However,the main chemistry of the Zhuozhanghe River was complex,and the main hydrochemical type of the southern source of the river was HCO_(3)-SO_(4)-Na-Ca,and in the western source was HCO_(3)-Na-Ca.The hydrochemical type in the northern source changed from HCO_(3)-SO_(4)-Ca-Mg to HCO_(3)-SO_(4)-Cl-Na-Mg.It is found that water-rock interaction is an important process in the evolution of water bodies in the upper Zhanghe River,so it is important to focus on mountainous karst processes for accurate assessment of water resources in the basin.
