摘要
选择吉林省西部典型苏打碱化土壤地区,对其地下水的基本水化学指标进行了测定,分析了地下水电导率与含盐量、矿化度和离子含量的关系。针对地下水离子组成的特点,对该区地下水的苏打碱化特征进行了分析。最后分别以电导率、矿化度和钠吸附比(SAR)为指标,对该区地下水质进行了初步评价与分级。
A typical sodic soil area in the west of Jilin province was selected for test region. Primary hydrochemical indexes of groundwater were determined. Relationships between electrical conductivity and salt content, mineralization of water, ions content were analyzed. Alkalization characteristics of groundwater were described based on its ionic compositions. Selected electrical conductivity, sodium adsorption ratio （SAR） and mineralization of groundwater for evaluating indicators, groundwater qualities were evaluated at the end.
