摘　　要：确定矿集区土壤地球化学基准值是矿山环境地质调查与评价的重要任务,而遴选出合适的地球化学基线值的定值方法是该问题的关键。以江西德兴铜矿集区表层土壤地球化学数据为依据,运用地球化学对比法、相对累积频率方法和标准化的方法分别计算了德兴铜矿集区表层土壤6种重金属元素的地球化学背景值,并将其与江西省土壤背景值对比。结合成土母岩重金属含量分析了各种基准值定值方法的适用性,结果证明标准化方法较适用于确定研究区表层土壤地球化学基准值。The determination of geochemical baseline in an ore concentration area is the basic task for investigating and evaluating the mine environmental geology, and the selection of appropriate method for calculating geochemical baseline is the key to this problem. With the topsoil in the Dexing copper ore concentration area as the research object, the authors employed geochemical comparison method, relative cumulative frequencies method and normalization procedure to calculate geochemical baselines of six heavy metals in the topsoil in the study area. Then, these geochemical baselines were compared with geochemical backgrounds of Jiangxi Prov-ince. In addition, an analysis was made in the light of heavy metal content of mother rocks. It is concluded that the geochemical base-line determined by normalization procedure is the relatively suitable one.
