| 摘 要： | 影响土壤硒区域贫民是的因子很多。本文通过主因子地计算，在影响土壤硒的诸因子中提纯出四个主因子（即土壤类型，土壤母质，土地利用类型及植被类型），并对我国４１个土类中的硒进行了区划，最后针对不同区域确定出土壤硒的安全阈值。这将为我国判定土壤硒的环境质量标准提供科学依据。

| Abstract: | Many factors can affect the regional differentiation of soil selenium. Among them, soil type, soil texture, land use type and vegetation type are four main factors by pricipal component calculation. 41 Soil types. were regionalized in China according to the study, and the safety threshold of soil selenium contents in different regions was determined. The results would provide scientific basis for formulating the environmental quality standard of soil selenium in China. |
