中文摘要	黑河是我国西北地区较大的内陆河，横跨山地，盆地和沙漠三大地貌类型区，用水矛盾尤其是经济建设与生态环境用水矛盾突出。该文在对黑河流域自然概况及水文特征研究的基础上，重点对黑河的水化学特征进行了较为全面的研究。分析了干扰河水的主要离子成分，水化学类型，河水的矿化度，总矿度，总碱度及河水的微量元素组成，并对水质状况进行了评价，提出了水环境保护的意见和建议。
英文摘要	Heihe is a relative larger inland river of Northwest China. It spans three major land form types of mountain, basin and desert areas. The water resources are extremely deficient. The water problem is outstanding, especially in the contradiction between economic construction and ecological environment. This paper, based on the investigation of the hydrologic characteristics in the Heihe watershed, focuses on studies of the chemical properties of the water there. A large section of the Heihe are dominated with HCO_3~- in anion and Ca~(2+) in cation, with orders in milligram equivalent percentage of HCO_3~- > Cl~- > SO_4~(2+) in anion and Ca~(2+) > Mg~(2+) > Na~+ + K~+ in cation. However, different orders occur at the hydrologic station of Zhengyixia, namely, HCO_3~- > SO_4~2 > Cl~- in anion and Na~+ + K~+ > Mg~(2+) > Ca~(2+) in cation. According to conventional hydro-geological methods, three types of river water can be classified by taking the major aqueous anions and cations milligram equivalents as criteria, i.e., bicarbonate, sulfate and chloride. Tests show that most of the samples belong to bicarbonate types. According to the sampling test, the total mineralization of river water varies between 365 ～ 751mg/l, total hardness varies between 3.93 ～ 10.46 me/l, and total alkality, between 3.17 ～ 7.30 me/l. This paper also analyses the trace element of river water in the Heihe and makes an assessment of the water quality of the region and policy implications to water conservation are presented.
