摘要： 为研究煤系地层内地下水、土壤元素含量特征以及质量状况，通过对研究区地下水及土壤化学成分进行了分析及质量评价。结果表明，地下水水化学类型以SO42--Ca?Mg和HCO3--Ca为主，微量元素含量最高的为Mn，平均值为4.92 mg/L；其次为Zn，平均值为0.47 mg/L；含量最少的为Cu，平均值为0.03 mg/L；pH平均值为5.00，属于酸性水；溶解性总固体(TDS)、总硬度(HB)、溶解氧(COD)平均值分别为1011.44 mg/L、659.65 mg/L、8.33 mg/L。土壤微量元素含量最高的为Cr，平均值为148.00 mg/kg，其次为Zn，平均值为107.76 mg/kg，含量最少的为Cd，平均值为0.43 mg/kg。质量评价表明地下水硫酸盐、Mn、Cr、Ni、pH、HB、TDS、COD均超标，综合质量级别为Ⅴ级。土壤污染超标元素为Cu、Cd、Ni，内梅罗综合指数为1.35，质量级别为中等。

Abstract: In order to discuss the element content and quality of groundwater and soil in coalstrata, chemical composition of groundwater and soil were analyzed and evaluated. The results showed that: water chemistry type of groundwater were most SO42--Ca?Mg and HCO3--Ca, in trace elements, contents of Mn was highest and its average was 4.92 mg/L; next was Zn and its average was 0.47 mg/L; the content of Cu was least and its average was 0.03 mg/L; pH of groundwater was 5.00 and belonged to acid water; average of TDS, HB, COD were 1011.44 mg/L, 659.65 mg/L, 8.33 mg/L. In trace elements of soil, the content of Cr was highest and its average was 148.00 mg/kg, next was Zn and its average was 107.76 mg/kg, the content of Cd was the least and its average was 0.43 mg/kg. Quality evaluation was showed: SO42-, Mn, Cr, Ni, pH, HB, TDS, COD were exceeded standard, comprehensive quality level was level of Ⅴ. Contents of Cu, Cd, Ni were all exceed standard, comprehensive index was 1.35 and comprehensive quality level were medium.
