摘　　要：对研究区煤矿开采背景下的土壤和地表河进行了重金属含量分析,并进行了质量评价。结果表明,地表河S1～S8样点Zn、Cd、Cu、As含量最高的为S1,Cr含量最高的为S3,Ni含量最高为S4;S1、S4、S5水样污染因子均为Cd、Zn,S2、S3、S6水样污染因子为Zn,质量级别均为中等。综合因子指数最大的为S1,质量级别为中等,最小的为S8,质量级别为好。土壤T1～T6样地As、Cu、Cr、Cd、Pb、Ni、Zn含量最高的为T1,As、Cu、Cr、Pb、Ni含量最低的为T5,Cd含量最低的为T6,Zn含量最低的为T4,样地污染因子均为Cd,质量级多为很坏,综合质量级别为中等-坏-很坏。The effect of coal minning on water quality and soil in karst area were studied.In S1～S8 river samples,the contents of Zn,Cd,Cu,and As were highest in S1,the content of Cr and Ni were highest in S3 and S4 respectively.The pollution factors of S1,S4,and S5 were all Cd and Zn,while S2,S3,S6 was Zn,its quality level were all medium.The comprehensive factor index of S1 was the largest,its quality level was medium,while S8 was the smallest,its quality level was good.In T1～T6 soil samples,the contents of As,Cu,Cr,Cd,Pb,Ni,and Zn were the highest in T1,while the contents of As,Cu,Cr,Pb,and Ni were the lowest in T5,the contents of Cd and Zn were the lowest in T6 and T4 respectively.The Pollution factors of soil in T1～T6 were all Cd,the quality level were almost very bad,and the comprehensive quality level were medium-bad-very bad.
