为揭示贵州省稻田土壤重金属的超标状况和空间分布特征,采集了92个稻田土壤样品,用icp-ms测定了样品的重金属含量,并运用单因子污染指数法、富集因子法和空间分析法对数据进行了分析处理。结果表明,贵州省稻田土壤的as、cd、cr、cu、ni、pb、sb和zn平均含量分别为(19.7±17.1)、(0.577±0.690)、(91.1±38.6)、(40.5±32.8)、(37.1±20.3)、(35.5±32.0)、(3.59±8.81)和(135±128) Mg/kg  89.1%的点位重金属超标,67.4%的点位为轻微(超标1~2倍)和轻度(超标2~3倍)超标  Ni、as、cd主要由地质高背景成因导致  在成矿区和成矿带上,出现源于人为活动的重金属超标,在一些点位和区域达到了中度超标(超标3~5倍)至重度(超标大于5倍)超标。
