    摘要:

    贵州省土壤全硒含量的范围为0.064-1.326mg/kg,平均值0.369mg/kg。全境上壤含硒有由北向东南和随地势下降而逐步增加的趋势。全省可划分为:1.低硒区2.中低硒区3.中硒区4.中高硒区。贵州多数地区土壤属中等含硒水平,少数上壤富硒,同时还有少量缺硒土壤分布。

    Abstract:

    The total Se contents of soils in Guizhou Province range from 0.064mg/kg to 1.326mg/kg, with an average of 0.369mg/kg, tending to increase as the terrian decends from north to south east. The whole province can be divided into four Se regions: (1) the region of low Se content; (2) the region of medium-low Se content; (3) the region of medium Se content; and (4) the region of medium-high Se content. In general, most of the soils in Guizhou have a medium Se level, and only a small part belong to Se-rich soils. Besides, there exists some distribution of low Se content soils in Guizhou province.
