摘要
通过对民勤沙区７眼机井７ａ来的地下水位观测及水质化学类型的分析测定，对地下水质的动态变化进行了研究，结果表明：随着地下水位的下降，水的矿化度有明显的下降趋势，水质化学类型变化的趋势是由硫酸、氯化物型转向重碳酸盐、氯化物型。
By observing and analysing underground water table of 7 am and chemical type of water quality of 7 driven well in sandy area of Minqin, the dynamtic varition of underground water quality have been studied in the paper. The results indicated that the mineralize degree of water declined obviously as underground water descend, and chemical type of water quality varied from sulfuric alid, chloride type to heavy carbonate chloride type.
