摘　　要：以2014年地下水污染调查数据为基础,依据《地下水质量标准》(GB/T14848-2017),采用单指标评价方法对新疆和田河流域绿洲区43组潜水样进行地下水质量评价。结果表明,绿洲区地下水质量总体很差,无Ⅰ类水和Ⅱ类水,72.1%的水样为Ⅴ类水,决定地下水水质类别的关键指标有溶解性总固体、总硬度、Cl-、SO2-4、Na+、Fe和F-等。水平方向上,浅层潜水质量差别不大;垂直方向上,浅层潜水水质劣于中深层潜水。绿洲地下水质量差主要与气候条件、地层岩性、水文地质条件等自然条件及人类活动有关。According to GB/T14848-2017 Standard for Groundwater Quality,the single-factor evaluation method was used to evaluate groundwater quality in oasis area of Hotan river basin based on the pollution survey data of 43 phreatic water wells in 2014.The results showed that groundwater quality in oasis was poor and 72.1% of groundwater samples were Ⅴ class water.The key indexes influencing groundwater quality were TDS,TH,Cl-,SO2-4,Na+,Fe and F-,etc.In horizontal direction,shallow phreatic water quality was not very different,while in the vertical direction,shallow phreatic water quality was inferior to the medium deep phreatic water.The poor groundwater in oasis area was mainly associated with climatic conditions,formation lithology,hydrogeological condition and other natural conditions and human activities.
