以青海东部富硒土壤为对象，研究了该区土壤及生物体中硒元素的含量、分布及迁移转化等地球化学特征。结果表明，该区土壤硒含量受古近系西宁群控制，土壤处于富硒水平，土壤呈碱性，且Se6+占总硒比例较高，土壤有效硒高，利于植物、动物及人体吸收。发现大蒜、小麦、油菜、牧草等作物对硒吸收能力较强，处于富硒土壤区的人群头发和家畜毛羽硒含量均较高。这一研究结果对该地区富硒土壤合理开发利用，具有重要的指导意义。

Geochemical Characteristics such as range, distribution and transformation of selenium in soils and organisms were measured with the study of rich selenium soils in the East of Qinghai Province. The results indicated the range of soil selenium was controlled by Xining Group, Paleogene System. The soils were alkaline at a rich Se level. Selenium with a valence of six was high in total selenium proportion. The content of available selenium was fairly rich, which had the advantage of being absorbed by plants, animals and human bodies. Some crops such as garlic, wheat, canola, pasture, have the strong absorptive ability of selenium. Both the human hair and farm animal hair and feather, from the district of seleniumrich soil, contain higher selenium. This result has important guidance purpose to the reasonable development of rich selenium soils in this area.

Key words: The East of Qinghai Province, Soil Se, Geochemical Characteristic, Enrichment factor.
