阿瓦提县地下水化学特征及其形成机理

Study on Chemical Characteristic of Groundwater and Formation Mechanism in Awati County

根据研究区37组样品水化学测试结果,利用SUFFER软件根据样点测试值绘制等值线图分析。由于区内各地段起主导作用的水文地球化学作用不同,地下水水化学特征形成具有在水平与垂直分布上的双重特征。分析结果表明:在研究区平面上,由北向南,地下水矿化度总体由低变高,水化学类型由HCO3.SO4—Mg.Ca型向C l.SO4—Na型过渡。在垂直方向上,地下水在200m勘探深度内存在"上咸下淡"和"上淡下咸"两种类型。

According to the chemistry test results of 37 water samples in Awati county, this paper used SUFFER software to draw contour in order to analyze groundwater chemical characteristic and formation mechanism. The groundwater has dual chemical characteristic in horizontal and vertical direction as the different function of hydrology geochemistry. The resuh shows that on the same plane from the north to the south the degree of mineralization increases and chemical type from HCO3 · SO4 - Mg · Ca transfers to Cl · SO4 - Na. On the vertical direction groundwater has two types in the 200m depth,that is from fresh to salty and from salty to fresh.
