摘　　要： 通过测定水中TDS、F-、Cr6+、电导率及土壤TDS等指标了解甘肃省环县各乡镇井水水质情况,分析了F-、Cr6+与TDS之间的相关性。结果表明,土样中TDS含量较水样中TDS含量稳定,高含量TDS土样主要集中在环县中东部,而高含量TDS水样集中在环县东部;水中TDS及对应土壤TDS含量呈正相关性,水中F-、Cr6+含量均与TDS含量呈负相关性;环县西南部水体中所含F-浓度偏高,应针对性地建设水处理设施。 The well water quality in Huan County of Gansu province was detected from its total dissolved solids （TDS）,F^-,Cr^6＋,electric conductivity and soil TDS to analyze the correlation among F^-,Cr^6＋,and TDS.The results showed that the TDS content in soil was more stable than that in water,soil sample with high TDS was mainly grouped in the middle-east of Huan County,while water sample with high TDS was mainly grouped in the east of Huan County;There was a positive correlation between the water TDS content and soil TDS content in the research area,and there was a negative correlation between the F^-and Cr^6＋ content and TDS content;The water F-concentration of southwest Huan County was relatively high,therefore the water treatment facilities would be built accordingly.
