摘要
通过分析东天山北麓平原区160组地下水化学样品检测结果,采用舒卡列夫分类法和Piper三线图解法,研究了地下水化学分带特征。南部山前冲洪积砾质平原地下水化学类型为HCO_3·SO_4型,中部细土平原逐渐向SO_4·HCO_3型过渡,北部沙漠区以SO_4·Cl型为主,地下水溢出带为Cl·SO_4型。根据水化学剖面分析地下水各组分含量在径流途经中的变化趋势,分析结果表明,沿地下水径流方向由南向北,地下水中的硫酸盐、氯化物和钠都呈现出逐渐增大的变化规律,导致了水中溶解性总固体逐渐增大,水质逐渐变差。
Based on the analysis of the detection results of 160 groups of groundwater chemical samples in the plain at the northern foot of Dong Tians mountain,the characteristics of groundwater chemical zonation were studied by using Shug Kalev classification and Piper trigraph method.The chemical type of groundwater in the southern piedmont alluvial gravel plain is HCO3·SO4,the middle fine soil plain gradually turns to SO4·HCO3,the northern desert area is dominated by SO4·Cl,and the groundwater overflow zone is Cl·SO4.According to the hydrochemistry profile analysis of the variation trend of the content of various components in the groundwater in the runoff path,the analysis results show that along the direction of groundwater runoff from south to north,the sulfate,chloride and sodium in the groundwater show a gradual increase in the change law,resulting in the total dissolved solids in the water gradually increased,the water quality gradually deteriorated.
