摘要

针对娘子关泉域水化学分析不能即时评价且偏主观性的问题,加入离子空间分布图,对娘子关泉域岩溶地下水的13个水化学特征指标运用描述性统计、水化学类型、TDS和总硬度分布图等进行分析,并辅助以Pearson相关分析探究其成因。结果表明,个别水样超过地下水环境质量标准,Fe~(3+)、Na~+具有较大空间变化,其他元素相对稳定;除少部分为微咸水和软水、微硬水、硬水,大部分地区为淡水和极硬水;地下水水化学类型以HCO_3-Ca·Mg、SO_4·HCO_3-Ca、SO_4·HCO_3-Ca·Mg型为主,部分补给区和径流区已转变为硫酸盐类型为主的水。该水化学特征成因主要受工矿产业影响,其次受水岩作用和农业、生活污染的影响。
        Aiming at the problem that Niangziguan spring water chemistry analysis can not be evaluated immediately and is partial to subjectivity,the ion spatial distribution map is added.Thirteen indicators of karst groundwater in Niangziguan spring area were analyzed by descriptive statistics,hydrochemical types,TDS and the total hardness distribution map,and Pearson correlation analysis was used to explore the cause of formation of karst groundwater in Niangziguan spring area.The results show that individual water samples exceed the environmental quality standard of groundwater,Fe3+and Na+have great spatial variability and other elements are relatively stable;Except for a small part of brackish water and soft water,micro-hard water and hard water,most areas are fresh water and extremely hard water;The groundwater hydrochemical types are mainly HCO3-Ca·Mg,SO4·HCO3-Ca,SO4·HCO3-Ca·Mg,the partial recharge areas and runoff area has been transformed into sulfate type water.The hydrochemical characteristics are mainly affected by industry and mineral industry,followed by water-rock interaction,and agricultural and domestic pollution.
