摘要
本文初步分析了宁夏海原盆地地下水化学、同位素特征,认为:地下水化学分布存在着一定的分带性,符合干旱区盆地的水质演化规律。水-岩相互作用从补给区的以溶滤-混合作用为主逐渐演变成排泄区的以溶滤-蒸发作用为主。
The features of chemistry and isotope for the groundwater in Haiyuan Basin, Ningxia Municipal Region are preliminarily analyzed. The results show that a stripe zone exists in the chemical distribution of the groundwater, which is in conformity with the evolution law of water quality in arid basin. The water-rock interaction is changed from the dissolution-mixture action in recharge area to the dissolution-evaperation action in discharge area.
