摘要
依据《地下水水质标准(DZ/T0290-2015)》,采用单因子评价法对新疆喀什地区西部62组水样进行地下水质量现状评价。结果表明,喀什地区西部地下水质量极差,以Ⅴ类水为主,潜水、浅层承压水和深层承压水点位超标率分别为100.0%、96.3%和100.0%;影响地下水质量的评价指标主要有SO^(2-)_4、总硬度、TDS、Na^+、Fe、Mn和Cl^-等。研究区地下水水质极差主要与干旱的气候条件、原生地质环境、地下水开采、生活和工业污染以及农业活动等的影响有关。
The single-factor evaluation method was used to evaluate the groundwater quality status based on the 62 groundwater samples of western Kashgar area,Xinjiang in 2014.The results showed that the groundwater quality was poor and groundwater quality category was mainly for the V class water.The exceeding standard rates of phreatic water,shallow confined groundwater and deep confined groundwater were 100.0%,96.3% and 100.0%,respectively.The main evaluation indexes of influencing groundwater quality were SO^（2-）_4,total hardness,TDS,Na~＋,Fe,Mn and Cl^-,etc.The reasons for poor groundwater quality were associated with the arid climatic conditions,protogenic geological environment,groundwater exploitation,the influence of domestic and industrial pollution and agricultural activities.
