摘　　要：为确定巴里坤-伊吾盆地地下水优先控制污染物,文章采用盒须图法和累积频率法对地下水中无机指标的背景值进行厘定,使用以分类组合为基础的改进内梅罗指数法筛选地下水无机优先控制污染物;采用基于检出率、检出浓度和污染物毒理学性质构建的有机优先控制污染物识别方法对有机污染物进行筛选;采用绝对主成分分析-多元线性回归模型和土地利用类型分析优先控制污染物来源。结果表明:无机优先控制污染物有TH、TDS、Na^(+)、Cl^(-)、SO_(4)^(2-)、NO_(3)^(-)、Fe和F^(-),其中,TH、TDS、Na~+、SO_(4)^(2-)和Cl^(-)主要受到与水-岩相互作用有关的自然影响因素,F^(-)和NO_(3)^(-)主要来源于农业生产活动,Fe主要来源于矿业、工业活动;有机优先控制污染物为1,2-二氯苯,来源于农业生产中化肥农药的使用。In order to determine the priority control pollutants of groundwater in the Barkol-Yiwu Basin,the background val⁃ues of inorganic indicators in groundwater were determined by the box whisker diagram method and the cumulative frequency method,and the improved Nemero index method based on the classification combination was used to screen the inorganic pri⁃ority control pollutants in groundwater.Organic priority control pollutants identification method based on detection rate,detec⁃tion concentration and toxicological properties of pollutants was used to screen organic pollutants.The absolute principal com⁃ponent analysis-multiple linear regression model and land use type analysis were used to preferentially control the source of pollutants.The results showed that the inorganic priority control pollutants were TH,TDS,Na^(+),Cl^(-),SO_(4)^(2-),NO_(3)^(-),Fe and F^(-).Among them,TH,TDS,Na^(+),SO_(4)^(2-)and Cl^(-)were mainly affected by natural factors related to water-rock interaction,F-and NO_(3)^(-)was mainly derived from agricultural production;Fe was mainly originated from mining and industrial activities.The or⁃ganic priority control pollutant was 1,2-dichlorobenzene,which was derived from the use of chemical fertilizers and pesti⁃cides in agricultural production.
