摘　　要：通过1250000多目标区域地球化学调查、取样和化验,获得了晋中太谷县北部地区表层土壤27项指标数据,研究其分布特征,并依据相关规范进行了土壤质量评价。结果表明,太谷县北部地区土壤养分主要以中等—缺乏为主,在整个研究区内占比为94.20%,土壤环境质量综合等级总体上为一等清洁。耕、园地的土壤质量较好,以优质的一等和良好的二等土壤为主,占各自土地类型面积的55.70%和50.84%,研究区内土壤质量总体较好,硒土壤适量区广泛分布,当地政府应合理引导当地居民进行富硒农产品的开发,创造更大的经济价值和社会效益。Through a 1250000 multi-target regional geochemical survey,sampling and testing,27 indices of topsoil in the north area of Taigu County,Central Shanxi are obtained to study their distribution characteristics and evaluate soil quality according to relevant standards.The result indicates that soil nutrients in the north area of Taigu County are predominantly moderate to deficient,accounting for 94.20%of the entire study area.The overall soil environmental quality is rated as Grade I,indicating a clean status.The soil quality in cultivated and garden lands is relatively good,predominantly featuring Grade I(high quality)and Grade II(good quality)soils,which account for 55.70%and 50.84%of the respective land types.The overall soil quality in the study area is good,with extensive distribution of selenium-rich soils.The local government should strategically guide local residents to develop selenium-rich agricultural products,creating greater economic value and social benefit.
