摘要
为研究汉阴县地下水化学特征,共采集100件泉水或井水样品,运用数理统计、Piper三线图等方法分析了汉阴县地下水特征。结果显示研究区内地下水中Ca^(2+)为优势阳离子,HCO_(3)^(-)为优势阴离子。地下水中Ca^(2+)、HCO_(3)^(-)的变异系数较小,其在研究区地下水中的含量较稳定;Na^(+)、Mg^(2+)、SO_(4)^(2-)和Cl^(-)变异系数较大,其在研究区地下水中的含量变化较大;表明Na^(+)、Mg^(2+)、SO_(4)^(2-)和Cl^(-)是敏感因子易随外界环境因素影响发生变化。p H均值为6.9,总体上呈弱酸性,部分呈中性或弱碱性,地下水p H稳定,众数集中,在区域上变化很小。汉阴县地下水化学类型以HCO_(3)-Ca型为主,以HCO_(3)-Ca·Mg(Ca·Na)、HCO_(3)-Ca·Mg·Na、HCO_(3)·SO_(4)-Ca(HCO_(3)·SO_(4)-Ca·Mg)型等为辅。查明了汉阴县地下水的水化学特征,可为汉阴县农村或城镇饮用地下水安全提供参考依据。
In order to study the chemical characteristics of groundwater in Hanyin County,a total of 100 spring or well water samples were collected and analyzed by mathematical statistics and Piper Plot.The results show that Ca^(2+)is the dominant cation and HCO_3~-is the dominant anion in groundwater in the study area.The variation coefficient of Ca^(2+)and HCO_3~-in groundwater is small,and the variation coefficient of Na~+、Mg^(2+)、SO_4^(2-)and Cl~-in groundwater is large,and the variation coefficient of Ca^(2+)and HCO_3~-in groundwater is small,and the variation coefficient of Na~+、Mg^(2+)、SO_4^(2-)and Cl-in groundwater is large.The results showed that Na~+、Mg^(2+)、SO_4^(2-)and Cl~-were sensitive factors,which were easy to change with environmental factors.The average p H value is 6.9,it is weak acidity in general,neutral or weak alkalinity in part,the p H of groundwater is stable,the mode is concentrated,and the change is small in region.The chemical types of groundwater in Hanyin County are mainly HCO_3-Ca,supplemented by HCO_3-Ca·Mg (Ca·Na),HCO_3-Ca·Mg·Na and HCO_3·SO_4-Ca (HCO_3·SO_4-Ca·Mg).The water chemistry characteristics of groundwater in Hanyin.
