摘　　要：柴达木盆地南缘诺木洪地区地下水具有西北干旱盆地地下水水化学特征及分布规律,受盆地地貌、强烈蒸发极干旱气候条件控制和含水层岩性、埋藏条件、地下水渗流场的共同影响,形成了高山深盆特有的地下水水化学水平分带性。文中对地下水水质类型的形成演化过程进行了探讨,并就此类盆地地下水水化学类型缺失硫酸盐型水环带的成因机理进行了分析。The underground water of Nuomuhong area which located at the southern margin of Qaidam Basin has the same water chemical characteristic and distribution pattern of west-northern drought ba- sin of China. Under the comprehensive effect of groundwater runoff, lithology, topography, buried conditions and strong vaporation in drought climatic, the exclusively high mountain and deep basin horizontal zoning rule are developed. In this paper, the evolution process of underground water quali- ty type was discussed, And the formation mechanism of basin underground water type with sulfate ring shortage was analysied.
